Liebherr has introduced the latest crane in its EC-B ‘Tough One’ series, the 205 EC-B 10. This new model closes the gap between the company’s 172 EC-B 8 and 220 EC-B 10.

\n\n

The 205 EC-B 10 is capable of lifting up to 2,100 kg at its head with a jib length of 65 m. The crane provides a maximum load capacity of 10,000 kg at full jib length with a radius of up to 18 m. The jib comes in 2.5 m sections.

\n\n

Launched in June 2021, the 205 EC-B 10 is designed with a 45 kW hoist unit. The crane has a freestanding hook height of up to 54.4 m with 16 EC 240 tower system (system dimension: 1.6 m), and maximum freestanding hook height of 71.1 m with 21 HC 290 tower system (system dimension: 2.1 m).

\n\n

The 205 EC-B 10 features a compact design. Its slewing section can be transported together with the full jib and ballast using just four transport units. As the transport units are not used to full capacity, there is also space available for tower sections or central ballast. In addition, the use of the time-tested pickaback system for counter-jib transport enables efficient, safe and economical assembly in just a few lifts.

\n\n

The new flat-top model delivers further advantages during assembly. Slidable pins are used for connecting the slewing platform with the jib and counter-jib when assembling the crane’s upper section. Thus hammering is no longer required. This ensures not only safer, but also significantly more economical and convenient assembly.

\n\n

For operator comfort and safety on the construction site, the 205 EC-B 10 is fitted with the LiCAB cabin. From November 2021, the crane will also be equipped with the TC-OS multi-touch display, which is already available in the 125 K model.

\n\n

According to Liebherr, the first new 205 EC-B 10 cranes have already been sold in France and Italy.

Singapore-based company Presscrete Engineering Pte Ltd has been providing specialist engineering services since 1987. These include ground engineering, tunnelling, and civil & special engineering. The company was recently engaged to carry out maintenance work for Singapore’s Deep Tunnel Sewerage System (DTSS).

\n\n

DTSS is being developed by the national water agency PUB to meet Singapore’s long-term needs for used water collection, treatment, reclamation and disposal. Phase 1 of the project, which serves the eastern part of Singapore, was completed in 2008. Phase 2, which will connect Phase 1 to the southern and western part of the country, is ongoing and set to be completed by 2025.

\n\n

In this project, Presscrete Engineering was entrusted to handle the maintenance of the DTSS Phase 1. To help deliver the job, the company deployed a Sennebogen 653 E telescopic crawler crane. The machine is designed to operate on difficult terrain, thanks to its strong undercarriage traction.

\n\n

The Sennebogen 653 E is easy to transport and set up, ready to use in minutes even in tight spaces. The crane also operates quietly, making it ideal for construction projects in areas where noise levels are a concern.

\n\n

The DTTS system runs underneath major roads, so maintenance work can be quite a challenge. It requires the lifting and moving of people, material, and equipment throughout the DTTS conveyance system composed of link sewers, deep tunnels, and industrial tunnels. Here, some of the obstacles Presscrete Engineering had to overcome included narrow spaces, tight work schedules, noise level limitations, and multiple overlapping underground infrastructure.

\n\n

The Sennebogen 653 E, with its maximum lifting capacity of 50 t plus two heavy-duty hoisting winches that work side by side, could perform tasks safely such as lowering man cages, mini excavators, and outfall pipes for maintenance work.

\n\n

The crane’s decoupled engine mounts and soundproofing enables it to operate quietly, keeping the sound pressure level in accordance with 2000/14/EC. Its strong, full-power boom, which can be telescoped from 9.4 m up to 30.4 m even under load, allows flexible use on any construction site.

\n\n

Another challenge on the jobsite lied on the skill and teamwork of the operator and signalman to manoeuvre around the multiple overlapping underground infrastructure, such as underground power cable and water pipes. The electronic assist and build quality of Sennebogen 653 E made it highly stable during lifting operation, which allowed the operator to fully rely on the machine and focus his attention on the signalman and their surroundings.

\n\n

The crane’s cab offers an unblocked panoramic view with a sliding door and wide door opening. Ergonomically designed consoles and joysticks, including push buttons and switches are all easily accessible on the optimised control panel.

Singapore-based Sin Heng Heavy Machinery is the owner of the first Grove GMK5250XL-1 in the country. The 250-t capacity crane is believed to have the longest boom on any five-axle all-terrain machine and one of the highest capacities in its class. It will be put to use on construction, civil engineering and oil & gas projects throughout Singapore.

\n\n

Sin Heng chose the GMK5250XL-1 because it needed a compact and reliable crane to work on a range of projects. The machine features a 78.5 m Twin-Lock boom – which can be combined with an optional 17.8 m swing-away jib and extension of 2 x 8 m inserts for a total possible jib length of 33.8 m.

\n\n

The GMK5250XL-1 is powered by a Mercedes OM471LA Tier 4F/Euromot 5 engine with Mercedes G280 16-speed transmission inside a small footprint, offering excellent power while remaining highly manoeuvrable on tight job sites. The crane has particularly good specifications for road travel, and includes the Grove Megatrak suspension system.

\n\n

Manitowoc’s Megatrak independent suspension includes all-wheel-steering for better manoeuvrability. The system works by ensuring that all the wheels of the crane stay on the ground while travelling, keeping stresses and weight evenly distributed. Coupled with interchangeable counterweight slabs and self-rigging auxiliary hoists, operators can expect easy transport and handling from the crane.

\n\n

A Manitowoc customer since 2007, Sin Heng is an established provider of heavy lifting services in Singapore. The company is involved in the rental and sales of cranes, aerial lifts and other heavy lifting equipment. It also provides engineering services as well as sales and distribution of related equipment and parts. Sin Heng has purchased a wide range of Manitowoc’s cranes including Grove GMK5130, GMK6220L, GMK6300 and GMK4100L all-terrain cranes, plus RT9130 rough-terrain cranes.

Link-Belt has introduced its new 55-mt-capacity truck crane, the 65|HT, which is intended to replace the HTC-8660 Series II.

\n\n

The 65|HT comes with a new four-section, 11.2–35 m full-power boom that reaches a maximum tip height of 38.1 m. The crane boasts an all-new formed boom riding Link-Belt’s Teflon-impregnated wear pads, meaning there is no need to grease the boom – reducing the time and cost of upkeep.
\n
\nThe 65|HT features the next generation of emission standards with an EPA 2021 certified Cummins L9 engine that provides 260 hp at 2,000 rpm. Improved capacities over its predecessor are delivered through three optimised boom extend modes and an increase in maximum counterweight to 8,482 kg. Operator controls are available in either a dual or single axis configuration and have a fine metering feature for precise operation.

\n\n

The crane is also equipped with Link-Belt Pulse, a Link-Belt-designed operating system that utilises an in-cab display as a readout and operator interface with on-board diagnostics including the rated capacity limiter, wind speed, boom length and angle, radius of load, and crane configuration, just to name a few.

\n\n

In addition, durable textured and slip-resistant paint on all walking surfaces improves durability and footing. Vision package consists of cameras for winch-view, right-side swing view, rear-view backup, and right-side turn, giving the operator excellent jobsite visibility during travel, setup, and lifting.

\n\n

The optional lighting package offers a high-intensity LED work light mounted on the operator’s cab, two fixed LED lights and a remote-controlled articulating spotlight mounted on the boom base. A fully equipped 65|HT can reduce its transport weight to less than 29,483 kg with all counterweight removed.

Link-Belt Cranes has announced that the production of its new 45-mt TCC-550 telescopic crawler crane will begin soon, with shipments set to commence in the fourth quarter of 2021.

\n\n

The TCC-550 follows a long line of product improvements and introductions in Link-Belt’s telescopic crawler crane family. The predecessors to this model, the TCC-500 and TCC-450, were some of the company’s first telescopic crawler models to be introduced worldwide in 2006.

\n\n

The TCC-550 features a full-power, 11–35 m four-section boom with two boom extend modes (EM1 and EM2) and an impressive chart. The entire boom is greaseless and incorporates Link-Belt’s Teflon-impregnated wear pads for easy maintenance. Fly options include an 8.7-15.6 m two-piece bi-fold lattice fly, stowable, offsetable to 2, 20 and 40 degrees; maximum tip height is 50.44 m.

\n\n

Durable textured and slip-resistant paint on all walking surfaces is new and improves footing. The Vision Package consists of winch-view camera, rear-view camera and right-side swing camera, giving the operator excellent jobsite visibility during setup and lifting. Anchor points are located on the work platform of the TCC-550 for personal fall arrest equipment.

\n\n

The standard lighting package comprises a high intensity 360-degree LED work light mounted on the house and one high intensity 360-degree LED light attached at the top of the boom base section. Both lights can be controlled remotely inside of the operator’s cabin.

\n\n

The TCC-550 can work at three different track widths: 4.63 m fully extended, 4.12 m intermediate, and 3.49 m retracted. The crane offers two travel speeds and can travel up to 3.2 kph.

\n\n

In addition, the TCC-550 is able to move quickly and easily on or off the jobsite. With a standard counterweight package of 11,339.8 kg, the crane transports in just one load while staying under 45,359.2 kg. On the trailer, it travels at a height of 3.01 m and a width of 3.49 m.

Shimizu Corporation and its wholly-owned subsidiaries, SC Machinery Corporation and IHI Transport Machinery Co Ltd, have jointly commenced work on designing and building what is believed to be the largest and “most dynamic” movable tower crane in Japan, intended for construction of extra-large facilities.

\n\n

Called the S-Movable Towercrane, it will have a maximum working height of 152 m, maximum load capacity of 145 t, and 12.5 m radius. Shimizu said it will invest about 1.1 billion yen in this development, which is scheduled to be completed by June 2023. It is expected to give the company a competitive advantage “in securing the top spot for bids in the market forecast to be worth 5 trillion yen, and acquiring the highest contract share in onshore wind power construction projects.”

\n\n

Shimizu has observed that in line with the Japanese government’s objective to achieve carbon neutrality by 2050, interest in the renewable energy industry has greatly increased across the country, particularly in wind power generation, gaining numerous construction projects both offshore and onshore.

\n\n

“There has been a rising demand for construction of onshore wind power facilities using movable cranes,” said Shimizu. “Additionally, various power generating facilities that have passed their useful life when the Feed-In Tariff (FIT) system was implemented exhibited the need for equipment replacement and plant rebuilding, further fuelling the demand.”

\n\n

The company added, “Since the end of the FIT programme, larger and more efficient power-generating facilities have shown to be vital considering the falling prices of electricity and streamlining of construction.”

\n\n

The movable cranes available in the local market are currently limited to constructing mid-sized power generation facilities, about 100 m in height and generating 4 MW, explained Shimizu. Building a larger facility will require a larger crane, and for this reason, the company decided to develop the S-Movable Towercrane, which is capable of constructing extra-large onshore facilities up to 150 m in height and generating 5 MW.

\n\n

One of the highlights of the new crane would be a simple and straightforward disassembly of its mast and base, allowing it to be transported easily to the next construction site using a dolly (a self-propelled, wheeled transport vehicle).

\n\n

According to Shimizu, the development of the S-Movable Towercrane forms a key part of the company’s Investment Plan – which is under its Mid-Term Management Plan (2019-2023) – for investments in infrastructure, renewable energy, and new businesses.

The new 40-t-class telescopic crawler crane from Liebherr, the LTR 1040, is a lightweight version of the LTR 1060. It has a significantly reduced ballast, weighing 20 t less - 10 t of central ballast have been taken off the chassis whilst a further 10 t of counterweights have been removed from the slewing platform.

\n\n

According to Liebherr, the LTR 1040’s lifting capacities up to a medium radius significantly surpass those of competitors and its 40 m telescopic boom is approximately 30% longer than the standard models in this class. As such, most crane jobs can be performed without a folding jib.

\n\n

The new LTR 1040 is suitable for assembling prefabricated components. For example, the crane will hoist up to 8.6 t with a radius of 10 m throughout its entire 360° operating range. When it is fully raised, the lifting capacity of the 30.7 m extended telescope is 18.8 t and when fully extended, the 40 m boom can hoist 10 t. Using a 16 m double folding jib, the LTR 1040 can achieve a maximum hoist height of 55 m and can hoist a weight of 3.1 t in this configuration.

\n\n

The LTR 1040 weighs just 43.5 t, including its 5.6 t of ballast. The axle loads for transport are less than 10 t for a three-axle tractor unit and a four-axle semi low loader. By removing 5 t of ballast, the LTR 1040’s weight can be reduced to 38.5 t, resulting in a gross transport weight of less than 60 t.

\n\n

The crawler travel gear is retracted to a width of 3.0 m for transport. The low crane height of just 3.15 m ensures that economical standard semi low loaders can be used.

\n\n

With a 2.5 m erection jib and a second hoist unit, the LTR 1040 can also carry out work in two-hook mode. The load absorbed with the erection jib by the low loader is transferred to the second hook on the telescopic boom. This means that prefabricated components can be rotated into the correct position and moved to the installation site on the crawler travel gear.

\n\n

The LTR 1040 can hoist up to 17.7 t with four-line reeving of the hook block on the erection jib. The runner on the crane can handle loads of up to 9 t as it can also use a double reeving constellation.

\n\n

The fine gradation of up to 0.3, 0.7, 1.5, 2.5 and 4 degrees ensures perfect lifting capacities even on uneven site terrain types, said Liebherr. On restricted sites, the LTR 1040 can also operate with its crawler tracks retracted to a width of 3 m.

\n\n

For safety and convenience, the crane operator can access the cab in any slewing platform setting using folding ladders, a fixed platform on the crawler track and an extra-wide step on the cab. There is no need to climb over the crawler tracks and chains.

The new Potain MDT 489 topless crane from Manitowoc fills the gap between the manufacturer’s popular MDT 389 and new MDT 569 models and is ideal for large-scale construction and infrastructure projects, especially the installation of large, prefabricated components, as well as for shipyards and mines with heavy loads to handle.

\n\n

The MDT 489 delivers a high capacity with a maximum load of 20 t or 25 t and a 80 m jib for broad coverage and reach on the jobsite. In addition, its compact configuration enables the crane to operate on tight and congested sites.

\n\n

All components, save the slewing mechanism, can be transported in standard-sized shipping containers. According to Manitowoc, the rotating section of the MDT 489 can be transported in just nine containers – which is four or five fewer than needed for a typical crane of this size, decreasing transport cost and complexity, as well as making access to the jobsite much simpler.

\n\n

The MDT 489 is also quick to assemble on the jobsite. With a 80 m jib and 50 m mast, assembly takes a maximum of two days and requires very little space.

\n\n

The crane can be placed on a 6 m or 8 m cross base platform and assembled in various configurations to best use the space and equipment available on the jobsite. The jib has been designed for easy and efficient erection with built-in slinging points. The jib sections can be assembled in different configurations to offer jobsite flexibility according to the assist crane size and ground space available. The heaviest jib section weighs only 6.7 t.

\n\n

Latest Potain technologies

\n\n

Using Manitowoc’s crane control system (CCS), the MDT 489 can be set up in just 15 minutes. Moreover, this feature promotes highly controlled and efficient operation throughout the crane’s time on the jobsite. The trolley offers two falls for fast duty-cycle lifting or four falls for heavy lifting.

\n\n

The wire ropes for the trolley can be tensioned and then the sensor recalibrated simply by using a push-button inside the operator cab. This is ideal for long-term jobsites that require more frequent tensioning. Once the MDT 489 has completed its work on the jobsite, it can be quickly and easily disassembled, ready to make way for other cranes or move on to its next job.

\n\n

Customers have the option of the new high-performance 110 HPL winch or the 150 HPL (the 132 HPL and 180 HPL are available for the North American market). Productivity is dramatically increased with the new 110 HPL winch, as lifting speeds are up to twice that of the older 100 LVF winch. This feature, in combination with new motor brake management and a new architecture that facilitates maintenance operations, means the 110 HPL winch speed up construction times, improve overall driving comfort and provide more precise load placement.

\n\n

These performance improvements by the 110 HPL winch do not increase power consumption, and maintenance is easier, said Manitowoc. Additionally, with the Power Control functionality, it is possible to limit the maximum electric power required for the crane operation without impacting low-load and no-load working speeds.

\n\n

Like all Potain CCS cranes, the MDT 489 is equipped with the CraneSTAR Diag solution. Potain‘s remote diagnostic tool allows the customer to consult the machine‘s activity in real time. Thanks in particular to the forecasting of maintenance operations and advanced diagnostic assistance, the customer optimises the availability of its cranes and the return on investment. The recovery of operating data allows the measurement of the crane utilisation and load rates in order to optimise productivity and operational efficiency on construction sites.

\n\n

The Potain MDT 489 topless crane combines the capacity necessary for large construction projects with a compact crane configuration for the tightest and most congested jobsites, enabling contractors to access more sites and complete the job efficiently and profitably.

Spanish tower crane manufacturer Jaso has added flat-top models to its product range. These include the J200.12 and J200.10 with 12 t and 10 t capacity respectively, offering a maximum radius of 67.5 m.

\n\n

The J200.12 has a tip load of 1.7 t with a single trolley and single reeving mode (ST-SR), and 1.5 t at 67.5 m with a single trolley and double reeving mode (ST-DR). As an option in SR reeving mode, the J200.12 can lift 1.9 t at 67.5 m.

\n\n

The J200.10 features a SR-DR trolley and can lift 1.8 t at 67.5 m in SR-DR reeving mode. As an option in SR reeving mode, the crane’s tip load can be increased to 2.0 t at 67.5 m.

\n\n

The boom lengths for the new cranes start at 30 m and can be extended in 2.5 m increments. The swing radius with the full boom is 14.9 m, and it can be reduced to 12.9 m for booms of 52.5 m and less. Counterweight slabs are the lay-flat type, the same as the weights of the base ballast, common on all Jaso’s latest models. As an option, the counterweight can be steel framed for higher safety.

\n\n

The 12-t J200.12 comes with a 60 hp hoist, delivering a maximum speed of 152 m/min. An 88 hp unit is optional, giving a maximum speed of 225 m/min. For the two models, the hoist drums can be specified with Lebus grooving and the rope capacity is 1,378 m. The J200.10 has a standard 33 hp hoist, with an optional 60 hp unit.

\n\n

Both cranes use the standard 1.75 x 1.75 m tower system with 12-, 6- and 3-m-long sections. Maximum freestanding height is 50.1 m. To increase it, Jaso is developing the crane to fit the 2.16 m tower system for hook heights of nearly 83 m.

\n\n

For the base, Jaso is offering cruciform types 4.5 x 4.5 m and 6 x 6 m, for maximum hook heights of 48.1 and 54.0 m respectively.

\n\n

To simplify assembly, the heaviest component is the slewing platform with tower head at 6.7 t. Combining these two minimises the number of transport units.

\n\n

New with these cranes is the Eco mode system. In normal mode the crane runs on full power, while switching to Eco mode can provide 75% of the power. The Super Eco mode works with 50% of the normal power consumption. It allows a crane with a bigger hoist motor to also work on less current. This helps on sites with restricted power supply.

\n\n

Eco and Super Eco modes reduce the hoist speed but only when hoisting up. Lowering the hook is at same speed as when working in normal mode.

Jakarta-based contractor PT Indonesia Pondasi Raya (Indopora) has deployed its Potain Hup 32-27 self-erecting crane on a variety of projects over the last three years. Launched at bauma 2016, this crane model has the ability to combine typical tower crane operations with replicating many of the tasks performed by smaller, mobile material handling equipment – reducing costs and eliminating excess traffic on jobsites.

\n\n

Founded in 1977, Indopora is predominantly engaged in piling, retaining walls and ground engineering, for projects as diverse as housing, skyscrapers, underpasses and bridges. The company had traditionally rented conventional tower cranes on larger projects and mobile cranes, rough-terrain forklifts or telehandlers on prefabricated housing projects. But in 2018 it pursued a new strategy, purchasing a Potain Hup 32-27 on the recommendation of Multicrane Perkasa, the local Potain dealer.

\n\n

The crane proved an immediate hit, and it’s easy to see why. It features an adjustable two-section mast with a third section that can telescope out from the second to increase working height from 21 m to 27 m, with the jib in the horizontal position.

\n\n

With a maximum capacity of 4 t, or 1 t at its 32 m jib end, the crane provides even greater versatility with a choice of three luffing positions (10°, 20° and 30°) that increase the maximum under-hook height to 40 m. Folding back the jib to its alternate configurations of 23 m or 11 m is a swift and straightforward process. In total, over 20 separate crane configurations are possible.

\n\n

Proof positive

\n\n

The first opportunity for the Hup 32-27 to prove itself to Indopora came with the start of the Eco Home project, a five-storey apartment complex in Tangerang, West Java. “The crane was worked hard for a year, lifting precast concrete sections and handling other duties,” said Mr Wahyudi, owner of Indopora. “Its ability to work so well in such a confined location was extremely impressive.”

\n\n

Key to this ability is the small rear slewing radius of just 2.25 m, enabling the crane to be positioned closer to existing structures. It also offers two compact footprint options of 4 m x 4 m or 3.5 m x 4.42 m. Its innovative, dynamic unfolding movement enables setup in congested areas, while its integrated levelling system compensates for height differentials of up to 25 cm, or gradients of up to 8%.

\n\n

Next project after the completion of the Eco Home development was the Boxies Mall, another five-storey structure in western Bogor, 60 km south of Jakarta. This time the crane was used for about eight months, again lifting precast concrete and other materials.

\n\n

For such a relatively large crane, the Hup 32-27 becomes surprisingly agile once folded for transportation, packing down to a single 4 m tall, 12 m long package, which again impressed Mr Wahyudi: “We were able to move it quickly from one location to another. It could then be reconfigured rapidly, so the minimal downtime and wider coverage is extremely appreciated.”

\n\n

The quick setup time of the Hup 32-27 is made possible with Manitowoc’s innovative radio remote control unit. Its Smart Set Up software delivers simplified step-by-step information to the operator via the large, easily navigated colour screen and, once setup is completed, provides three operating profiles that vary the working speed to suit the application.

\n\n

“After three years of use, we are very pleased we made the switch to the Hup 32-27,” concluded Mr Wahyudi. “It has definitely boosted productivity and delivered cost savings, while simplifying the on-site logistics.”

\n\n

Other Indopora projects where the Hup has proved itself include the Jababeka Living Plaza Mall and the Indramayu Mall, both in West Java. And for projects where something a little larger is required, the company can always turn to its MC 310 K12 and MC 465 top-slewing cranes.
