International heavy lift and transport specialist ALE will build a heavy duty jib, up to 100 metres long, for its AL.SK 190 and AL.SK350 super heavy lift cranes.
Capacity will be 3,400 tonnes and its modular design will allow a range of configurations. On winches capacity of the large SK cranes is up to 4,000 tonnes and there is a 600 tonne auxiliary quick winch system. Heavier loads, up to 5,000 tonnes, will be lifted using a strand jack system.
Ronald Hoefmans, ALE technical director, said, “The AL.SK cranes have always been designed with a potential for a jib but it has previously never been required. We have received client requests to lift with heavier capacities to bigger heights. At ALE our priority is anticipate future challenges and provide an innovative solution for our clients.
“The new jib will enable us to achieve this and lift heavy loads to bigger heights with a larger radius. The jib will comprise a unique patented design with a wide strut. It is this special design which will boost the lifting capacity.”
Construction will include high strength fine grain steel up to S1100QL grade. The build is expected to start in March 2016 and be complete by the end of the year, ALE said. The first contract for the jib will be to lift modules weighing up to 2,800 tonnes to a height of 65 m.
