Moving into the market for big modular lifts, the 120,000tm SGC-120 can use its six winches, twin booms and specially designed ropeblock to lift a maximum of 3,200t. It can lift 600t at a radius of 100m.
Despite the size of the crane, its components, rope block included, can be transported in standard 20ft and 40 ft shipping containers.
Ropeblock said the engineering of the block was ‘extensive’. When the design and components were finally ready, the block was assembled outside RopeBlock’s plant in Oldenzaal, Netherlands.
The hook has five sheaves, each with six housings. The housings fit a total of 30 wire ropes with a diameter of 50mm each. The modular block may be configured for various capacities over 1,200 tonnes following removal of two sheave housings in the middle of the block. It can lift using a general hook or two double hooks in cast steel.
Sarens has commenced the reeving and load testing on delivery of the block, using the hook to lift 625t at a 120m radius on the full main boom.
