RopeBlock record hook block
By Alex Dahm18 February 2011
Dutch hook block manufacturer RopeBlock has built what it says is the world's largest for a land-based crane. With a safe working load of 3,200 tonnes, it is also the largest hook block built by the company.
Pictured assembled outside the manufacturer's plant in Oldenzaal, it weighs more than 108 tonnes. It has five sheaves for 50 mm wire rope in each of six housings giving a total of 30. The modular block can be configured for different capacities, including 2,400 and 1,200 tonnes, for example, by removing the two central sheave housings. It is a general purpose hook with a pair of cast steel double hooks.
Proof load testing will begin following the reeving due in March on the crane, the new 3,200 tonne capacity Sarens SGC-120 super heavy lifter.
