Kim Heng from Singapore (SG) is deploying a large fleet of crawler cranes, which are used on land and sometimes from barge. This impressive IHI CCH2800, a 280-tonne crawler crane, was used from a barge. In total is Kim Heng operating six of those crawler cranes.
The crane was fitted here with a 45 meter main boom, in this configuration is the crane able to hoist maximum 110.2 tonnes on a 9.8 meter radius or 16.1 tonnes on a 40.6 meter radius, then the right reefing is used.
The undercarriage of the CCH2800 is 9.18 meters long and 7.62 meters wide. Attached to the undercarriage is in total 16 tonnes of central counterweight.
The A-frame is in working position about 8.4 meters tall and can be folded downwards for transport over the road. To erect main booms with a length over 69 meters is an additional mast required, which will be installed between the A-frame and main boom.
The crane is powered by a Cummins QSB diesel engine with a power of 242 kW. The crane is fitted with two 13.5-tonne hoist winches, each equipped with a 28 mm wire rope.
The 9-part counterweight on the super structure has a total mass of 87.6 tonnes and has a 6 meter tailswing.
Both hoist winches are in use here, over the runner is the crane able to lift constantly 13.5 tonnes. Over the main boom can, due to the 6-part reeding, the crane lift maximum 75 tonnes. The main boom has an 18 meter base length and can in 3 meter steps be extended to maximum 90 meters.
A very sharp crane of Kim Heng!
For a possible transport over the road is it required to separate the crawler tracks from the undercarriage. A single track is 9.18 meters long, 1.57 meters wide and 1.37 meters tall. The mass for a single track is 23.3 tonnes.
