The new Potain MCT 275 is the latest launch from Manitowoc, expanding the company’s popular MCT range of topless cranes built in China. This new model has been designed for easier transport and assembly, plus high efficiency and reliability on construction projects.

\n\n

The crane was launched yesterday (29 July) during a virtual launch event at Manitowoc’s Chinese factory in Zhangjiagang, where the 10 t version of the MCT 275 was displayed with its full 70 m jib. This model has taken advantage of the advances and innovation Manitowoc made with the introduction of the MCT 325 and was largely been inspired by it.

\n\n

“With the increasing popularity of precast concrete construction, topless cranes like the MCT 275 are becoming the go-to solution for the speed and simplicity they bring to jobsites,” said Kwong-Joon Leong, regional product manager for tower cranes at Manitowoc. “The topless design allows multiple units to overlap on site and with the MCT 275 we’re giving customers a new choice in the 10 t and 12 t range. With its standout 70 m jib, we believe this crane will appeal to a wide range of companies and projects.”

\n\n

Available in two versions, the MCT 275 features jib length configurations from 30 m up to 70 m, in increments of 5 m. At its 70 m jib end, the MCT 275 can handle 2.3 t for the 10 t version and 2.2 t for the 12 t version, making it an excellent performer for long-distance lifting.

\n\n

According to Manitowoc, the MCT 275 can be set up within 1.5 days on a well-prepared site, with the full jib and counter-jib erected in four lifts. The complete upper part of the crane can be transported in six containers.

\n\n

The MCT 275 is designed to work with the 2 m x 2 m L68 mast systems and can be utilised with fixing angles on a regular high-rise construction project. Users can also assemble the crane in an internal climbing configuration or mounted on a chassis, for maximum versatility.

\n\n

In addition, customers have a variety of options for the hoisting, slewing and trolley mechanisms. The 10 t version offers the 60 LVF25 as standard and the 75 HPL25 as option, while the 12 t version offers the 75 LVFC30 as standard and the 75 HPL30 as options.

\n\n

The 60 LVF 25 is a 45 kW-rated hoist that has a rope capacity of 500 m and can lift 2.5 t at up to 88 m/min. The 75 HPL25 is a 55 kW-rated hoist that features a rope capacity of 834 m and can lift 0.35 t at up to 215 m/min. The 75 LVFC30 is a 55 kW-rated hoist that provides a rope capacity of 766 m and can lift 1.5 t at up to 114 m/min. The 75 HPL30 is a 55 kW-rated hoist that has a rope capacity of 845 m and can lift 0.2 t at up to 220 m/min.

\n\n

In 2014, Manitowoc launched its first Potain topless crane from the Zhangjiagang factory, the MCT 385. Over the years, the company has continued to innovate and added the MCT 205, MCT 85, MCT 325, MCT 565 and now the MCT 275 to complement the range. Manitowoc said the MCT 275 will ultimately replace its popular hammerhead top-slewing crane model, the MC 235.

Xian Xintuo Construction Machinery has deployed a Potain MCT 325 L16 tower crane – it is known as the MCT 328 in China - to build a new vocational school in the Chinese province of Xian. With investment from the OPEC Fund for International Development, the new Shaanxi Youth Vocational College is expected to open in the first quarter of 2021 and will provide skills training for youth.

\n\n

“First off, we are fans of the Manitowoc brand because they provide an innovative, advanced and comprehensive range of lifting solutions,” said Li Xutang, general manager of Xian Xintuo Construction Machinery. “Secondly, the Potain MCT 325 L16 was ideal for us because we could use the crane on construction of two buildings.”

\n\n

Shaanxi Youth Vocational College is an extension of the Shaanxi Provincial Communist Youth League School, which was established in 1952. Once the new vocational school opens in 2021, it will house up to 8,000 students and offer courses ranging from economics to communications and arts.

\n\n

On site since November 2019, the MCT 325 L16 works 10 hours daily lifting building materials such as rebar, formwork, steel tube and wood. For this project, the crane was configured with its maximum 75 m of jib, at a 48 m working height. The 16 t capacity MCT 325 L16 is a new addition for Xian Xintuo Construction Machinery and is expected to remain on site until August 2020.

Terex has announced that its Terex Cranes and Franna businesses will start manufacturing their product lines in Hosur, India, from 2021. Terex Cranes, whose portfolio includes tower and rough terrain cranes, is based in Fontanafredda and Crespellano, Italy; while Franna, a global provider of mobile pick and carry cranes, is based in Brisbane, Australia.

\n\n

Terex already has a strong manufacturing presence in India having first entered the market in 2009. Today, the company employs 600 staff across the country, which comprises an R&D unit of over 150 engineers.

\n\n

India is one of the largest mobile crane markets in the world, according to market research organisation Off-Highway Research (OHR). In 2018 there were record crane sales in India with almost 12,000 units being sold in the region, which also showed a growing demand for tower cranes.

\n\n

Terex expects to use its global engineering experience to make a positive contribution to the crane industry in India. The company said that its T-Link telemetry system – which provides customers with real time information on the performance of their machine - is an example of this. Telematics can be fitted to a number of Terex Cranes and Franna machines, ultimately maximising machine uptime, enhancing parts and service availability and also provides factual, up to date information from the field.

\n\n

“This is an exciting investment for Terex as we continue to promote and grow the Franna brand globally,” said Danny Black, general manager of Franna. “We have already had very good experience in the Indian market. Now, we have the ability to directly bring our market-leading Franna technology with local homologation to improve safety and performance for the Indian market.

\n\n

“This expansion will allow us to support our growth plans without causing any disruption to our production capacity in Australia, and will allow us to be a valued competitor in India. Given our proven manufacturing capabilities with the success of other Terex brands in India, such as Powerscreen and Terex Finlay, we are confident this decision will provide a positive outcome for Franna.”

\n\n

Marco Gentilini, VP of Terex Cranes added, “It is a thrilling opportunity for Terex Cranes to build on the experience and knowledge of the team at Hosur. We have been monitoring the market and we believe it is time to start a new journey that will give us a boost in the important Indian domestic market, but also reinforce our presence in the region.”

The Demag AC 220-5 all-terrain crane features an overall length of 14.52 m and width of 3 m, making it one of the most compact cranes in the 220-t capacity class. It has a maximum main boom length of 78 m, and is able to reach up to 99 m with an optional main boom extension.

\n\n

Thanks to its innovative IC-1 Plus control system, the five-axle AC 220-5 can handle lifts that are normally carried out by larger cranes. To do this, the system calculates the crane’s lifting capacity for every boom position as a function of the superstructure’s slewing angle, and in real time to boot. This means that the lifting capacity for a specific radius is no longer limited to the lowest value for a pre-calculated 360° lifting capacity, as used to be the case. Instead, the crane can always take full advantage of the maximum available lifting capacity. This advantage is particularly useful when it comes to lifts requiring an asymmetrical outrigger setup.

\n\n

The AC 220-5 is also cost-effective. Many of the components in Demag five-axle machines – such as hoist 2, main boom extensions, runners, swing-away rooster sheaves and heavy-lift attachments – are interchangeable, resulting in easy maintenance and thus lower operating costs.

\n\n

The AC 220-5 is powered by Scania DC13 diesel engines with an output of 331 to 405 kW, complying with EU Stage V / Tier 4f (405 kW) or EU Stage III A / Tier 3 (331 kW) regulations. The power delivered by these engines is safely and reliably brought to the road by fully automatic ZF TraXon transmissions with 12 forward gears and two reverse gears via three or four driven axles. In addition, five-axle steering, combined with independent rear axle steering and dynamic launch control, makes the AC 220-5 highly manoeuvrable.

Antar Cranes Services Ptd Ltd offers a safe, productive solution for contractors who need to carry out glazing work, by using a combination of an Oktopus vacuum lifting device and a Maeda mini crawler crane (spider crane).

\n\n

The Oktopus Glass-Jack GL-CC 600 DES vacuum lifting device is able to handle up to 600 kg glass elements. Manufactured by German company Wirth Gmbh, the device can lift both flat and curved glass panels as well as window components.

\n\n

The suction frame of the Oktopus lifting device can be tilted hydraulically by 120°, rotated 360° and swivelled by ± 35°. All functions are operated with the help of a radio remote control. A 24-V DC operated vacuum pump generates the necessary negative pressure in the suction pads.

\n\n

The Oktopus lifting device has an optical and acoustical warning equipment to indicate its deviations from the nominal condition. Even in case of complete failure of energy supply, the vacuum remains for at least five minutes in each suction pad, so that the load can be lowered safely.

\n\n

The MC285CWM-3 mini crawler crane from Japanese manufacturer Maeda features a compact design, with only 750 mm in width. It provides a lifting capacity of 2.82 t x 1.4 m, maximum working radius of 8.205 m x 0.15 t, and maximum lifting height of 8.7 m (on the ground). The crane’s travel speed is 0-2.2 km/h, with a 20 degree gradeability.

\n\n

The MC285CWM-3 is a new model equipped with various functions, including a programmable moment limiter, crane/outrigger interlock system, digital feedback remote control (wireless), four-fall/two-fall hook block, voice warning system and data logger.

\n\n

Andrew Tan, general manager of Antar Cranes further highlighted the importance of both units as a combined solution. “Using the Maeda spider crane together with the Oktopus lifting device results in manpower savings, as users can minimise the number of workers on site. At the same time, it increases safety when handling large and heavy glass panels at height. Imagine the number of manpower needed to handle a 600 kg glass panel. Ultimately, it would make the entire project safer. Compared with the traditional method, this solution can achieve a higher productivity improvement and also more time- and cost-effective.”

Manta Equipment has received two brand-new Potain MCT 565 M25 topless cranes in Singapore and recorded immediate success with both. Hock Guan Cheong Builder purchased the first crane from the company and is using it for residential construction projects, while BHCC Construction is renting the second one for use on housing projects.

\n\n

“We chose the MCT 565 because the Potain topless crane has better lifting capacity compared to the similar class of cranes from other manufacturers,” said Benjamin Goh, marketing manager at Manta Equipment.

\n\n

The MCT 565 M25 offers a 25 t maximum load capacity and jib length configurations from 30 m to 80 m in 5 m increments. At its 80 m jib end, the crane can handle an impressive 4 t. Despite its increased size, this new model stays true to the design characteristics of Potain topless cranes, with easy transport and erection combining with excellent on-site performance.

\n\n

Manta Equipment is one of Asia’s leading tower crane rental companies. It serves primarily the construction and infrastructure sectors in Singapore, Hong Kong and Macau. In Singapore the company has been leasing Potain cranes to customers for over 25 years.

\n\n

“Since the MCT 565 launched at bauma China 2018, popularity is continuing to grow,” said Darren Tan, regional sales manager for tower cranes at Manitowoc Cranes – Greater Asia Pacific. “With many contractors preferring topless cranes and job sites using heavier construction materials, we expect to see more demand for the MCT 565, which is now the largest topless crane from Potain’s Asia Range.”

Featuring a lifting capacity of 650 m at a radius of 12 m and a maximum load moment of 9,152 meter-tonnes, the Demag CC 3800-1 lattice boom crawler crane is a cost-effective option for various projects. It is also suitable for erecting wind turbines with a hub height of up to 117 m without a Superlift system.

\n\n

The Demag CC 3800-1 comes with a 144-m main boom. However, the crane’s maximum system length can be extended all the way up to 171 m with the optional boom booster. The welded steel structure consists of up to seven sections with a length of 12 m and is designed to be directly mounted on the crane. It also boosts the main boom’s stiffness, further increasing its lifting capacity.

\n\n

When equipped with the boom booster and a lightweight rigid lattice jib, the CC 3800-1 can reach a maximum hook height of 185 m and lift loads of up to 71.5 t. Thus, the crane can tackle lifts that would normally be handled by cranes in the 750-t class.

\n\n

With the optional ‘Fall Protection Device’, the CC 3800-1 offers maximum safety during setup and disassembly. So if a person on the lifeline falls, the system is able to arrest their fall at a large distance from the ground, significantly lowering the risk of injury.

\n\n

The Superlift Split Tray, which is also optional, features quick coupling technology that makes it possible to easily uncouple the counterweight that is no longer needed after erecting the main boom. After doing this, the crane can simply move with the Superlift counterweight that is actually needed, saving assembly time, minimising the amount of personnel needed, and eliminating the need for an assist crane.

\n\n

The optional Flex Frame unit can be used to replace the standard telescopic cylinder. As such, the Superlift counterweight radius can be adjusted to any dimension between 13 m and 21 m with the full counterweight. This means less counterweight needs to be set up and removed, significantly reducing setup times.

\n\n

Available as Demag PC 3800-1 pedestal crane

\n\n

Demag also offers the CC 3800-1 crawler crane in a different form as the PC 3800-1 pedestal crane, which outdoes its ‘brother’ by 100 meter-tonnes with a load moment of 9,252 meter-tonnes. The Demag PC 3800-1 is available as a complete crane or as an additional carrier, and the quick coupling system makes it possible to easily switch between the crawler and pedestal carriers.

\n\n

A Demag PC 3800-1 equipped with axle lines can be easily configured for an axle load limit of 12 t or a total vehicle weight of less than 100 t, depending on the relevant regulations determining whether a vehicle is street-legal.

\n\n

At the work site, a 390-kW Mercedes Benz diesel engine delivers ample power under all operating conditions. Moreover, the crawler tracks can be controlled independently of each other, as well as in opposite directions, with a tractive force of 1,400 kN per side.

The latest telescopic crawler crane from Link-Belt, the 75-t TCC-800, comes with a new four-section 11.8 – 36.5 m full-power boom that reaches a maximum tip height of 56.2 m with full boom and Link-Belt’s SmartFly pinning system.

\n\n

The SmartFly system helps to ensure proper fly erection and stowage sequence while minimising work at height. The TCC-800 offers optional one or two-piece 10.6 – 17.6 m fly.

\n\n

According to Link-Belt, the TCC-800 will begin field-testing soon and its first shipments is scheduled to take place in the fourth quarter of 2020. The company said the crane’s predecessor, the top-selling TCC-750, has been a cornerstone of the telecrawler market since its initial debut in 2008.

\n\n

New to Link-Belt’s telecrawler lineup is variable side frame track positions (V-CALC) on the TCC-800. “VCALC, in the case of the new TCC-800, offers the added flexibility to operate the crane with side frames in asymmetric configurations. Pulse 2.0 monitors actual side frame position, auto-selecting the correct chart,” explained Scott Knight, Link-Belt’s product manager for lattice and telescopic crawler cranes.

\n\n

The TCC-800’s variable side frame combinations, new cab with 20 degrees of tilt and Pulse 2.0 offer an operator a multitude of options for any jobsite - everything from pile driving, bridgework to plant work, and general construction. The crane also has an optional wireless remote control system, which allows the operator to be out of the cab and still have control of the machine.

\n\n

The TCC-800 will utilise a Stage 5 dual-compliant Cummins QSB 6.7 engine with 232 hp at 2,000 rpm for greater fuel economy, improved quiet operation and cold-start capability. Other advancements include pressure read-out on all hydraulic circuits, viewable on Pulse 2.0 display.

\n\n

Total vision package with right-side swing camera, winch-view camera, and rear-view camera give the operator great jobsite visibility during setup and lifting. Single axis or joystick controls are also available both offering operator selectable foot or hand controls for travel operation. Textured paint on all vertical surfaces and slip resistant paint on all horizontal surfaces improves durability and footing.

\n\n

In addition, new high-performance variable displacement pumps provide power control and load sensing on the TCC-800 for smooth functioning of all operating processes. Matching 19 mm grooved drums have 254.2 m of rope capacity with 7,656.6 kg maximum line pull and 147 mpm maximum line speed. The list chart on the TCC-800 also includes a maximum four-degree list chart for increased performance in varying jobsite conditions.

\n\n

The TCC-800 self-assembles with 17,463 kg of upper counterweight and two 1,360-kg sections of carbody counterweight. For transport, the crane moves in two loads: main unit transports under 45,359 kg with fly, side frames attached, hook block and ball, lifting sheave and full tank of fuel; overflow includes counterweight sections and stays below 20,184 kg. Clearance height on a lowboy transport trailer stays below 3.9 m.

The Tadano GTC-1800EX telescopic boom crawler crane had been developed and built at Demag’s Zweibrücken facility in Germany, and made its concept debut at bauma 2019. Now that Demag is part of the Tadano Group, the crane was recently relaunched as the Tadano GTC-1800EX at Conexpo 2020. It is expected to be available in the second half of 2020.

\n\n

The GTC-1800EX closes the gap between 130- and 220-t capacity classes. The crane has a lifting capacity of over 150 t and a maximum load moment of 590 meter-tonnes. It has a track width that can be adjusted as necessary in both symmetrical and asymmetrical configurations, so that it can be used for applications in which space is at a premium, such as bridge construction projects.

\n\n

The crane is also perfect for doing construction work, where it is not only able to move and telescope components, but also luff down and retract the boom and then travel underneath roof structures to get to where it needs to be. In addition, the GTC-1800EX is suitable for use as an assist crane, as well as for carrying out wind turbine pre-assembly work.

\n\n

Since the load charts for its 60-m-long main boom are excellent even when lifting on inclines of up to 4°, the use of the GTC-1800EX requires less topographical ground preparation on-site than a lattice boom crawler crane, explained Tadano. For example, the GTC-1800EX can lift a full 34 t at a radius of 12 m when working on an incline of 4° with the main boom at a length of 30 m.

The crane’s 60-m main boom length can be increased if necessary. Mian boom extensions with lengths of 5-, 11-, 17-, and 23-m that can be mechanically and hydraulically offset are available, meaning that a maximum system length of up to 83 m is possible. The 5-m extension can be folded onto the side of the main boom for transport to save space.

Manoeuvrable and powerful crawler drive

\n\n

The GTC-1800EX provides nearly the same manoeuvrability and ease of operation as an excavator with its travel pedals, said Tadano. And the fact that the joysticks can be used to control the tracks complements the machine’s convenient controls. Part of this is feasible thanks to the crane’s outstanding traction force and durable B9HD track components with bolt-on double grouser shoes or flat track shoes.

\n\n

Such a robust design, which features a powerful travel drive, provides the crane with a traction force of 1,450 kN. This is far higher than that of competitor models in the larger 220-t-class, claimed Tadano, and also allows the GTC-1800EX to turn on a dime under load, even with the narrowest track width. The crane’s gradeability is 50%, maximum travel speed is 2.1 km/h and ground clearance is 420 mm.

\n\n

There are different track widths with three standard positions of 3.5-, 4.75- and 6-m, as well as the continuously variable track widths, which can also be used in an asymmetrical configuration. The tracks can be adjusted both when stopped and when travelling, while the control system monitors the relevant parameters to ensure the crane remains within an allowable configuration.

\n\n

The GTC-1800EX is also equipped with an intelligent control system based on the Demag IC-1 Plus control system. It automatically determines the permissible lifting capacity under consideration of a number of factors, such as ground incline, slewing angle, and track adjustment.

\n\n

The transport width and height of the base crane are 3 m each, making the GTC-1800EX a highly compact machine. The heaviest transport unit weighs 47 t - but if necessary, this weight can be reduced to 42 t by simply removing the extension beams used to adjust the track width. The two crawler units have a gross weight of approximately 18.5 t each when equipped with 1-m track shoes; the two central ballast units weigh 7.5 t each; and the counterweights, including the base plate, weigh 45 t. The maximum operating weight of the crane is just under 150 t.

\n\n

Efficient setup

\n\n

The crane’s setup operation also emphasises on safety. Since most assembly steps can be controlled with the remote control or from the cab, the rigger does not have to work in the danger zone. Furthermore, most of the couplings are hydraulic quick-connect, which results in fast and efficient work. The crane is fitted with permanently installed outriggers including outrigger pads, which enable the base crane to be conveniently unloaded from a lowbed trailer.

\n\n

The self-assembly operation of the crane includes the installation of two 7.5-t central counterweights that mount on the carrier, the crawler frames, the 45 t upper counterweight stack on the superstructure and the second hoist.

\n\n

The accessibility concept of the GTC-1800EX is designed to enable comfortable and efficient work on the crane. This is the case during transport, setup, and operation – even when the tracks are being adjusted as the placement of the permanently installed grating platforms adjusts automatically.

\n\n

The GTC-1800EX can als be fuelled while on a lowbed trailer, and the cab can be easily accessed during setup in order to start the machine for self-assembly. Permanent ladders and ladder attachment points for the included loose ladder are located strategically around the crane for access to key components during all stages. Plus, there are anchors for a personal fall protection system at the intended ladder support points.

\n\n

Environment-friendly engine

\n\n

The GTC-1800-EX is driven by an MTU six-cylinder engine with an output of 230 kW and a torque of 1,300 Nm, which complies with Euromot 5 specifications and also Tier 4 Final specifications for the US market. The crane offers two operating modes: Eco mode and Power Boost mode. At a speed of 1,500 rpm, the diesel engine will run in an Eco mode that optimises fuel consumption, whereas at a speed of 1,800 rpm it will have a Power Boost function available. This provides a noticeable output increase and makes it possible to carry out simultaneous movements at high output or speed during crane operation.

\n\n

The two hoists of the GTC-1800EX also offer an innovative technological feature. The primary and auxiliary hoists are technically identical, with both featuring a 245-m-long, 26-mm-thick, wire rope with a high line pull of 13.9 t. The wire rope’s high line pull makes it possible to lift heavy loads with low reeving, saving time during setup and re-reeving.

\n\n

Tadano and telecrawlers

\n\n

According to Tadano, there are good reasons for incorporating the new GTC-1800EX into its brand. First, the Group has a long tradition with these products and a strong line of telecrawlers. As such, the integration is highly relevant and consistent from a technological point of view.

\n\n

Second, the move is a logical step in terms of corporate strategy. “Our goal is to become ‘One Tadano’. With the first telecrawler produced in Germany and branded by Tadano, this vision is now becoming a reality,” explained Ingo Nöske, director of product management for crawler cranes at Tadano.

\n\n

He added that this will strengthen cooperation between German and American colleagues within Tadano in the future. The Group can take advantage of the synergies and the ‘best of both worlds’ can flow into the development of new products – as is the case with the GTC-1800EX telecrawler, which has the Demag IC-1 Plus control as well as the IC-1 Remote telematics system technology.

\n\n

“With the integration of the GTC-1800EX into the Tadano brand, we’re bringing the lone warrior into the family, so to speak,” said Mr Nöske. The situation is different with the AC and CC cranes. These will continue to be marketed under the Demag brand.”
