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.

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.

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.

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.

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.
