ALE has announced plans to build a heavy duty jib with lengths up to 100m that can fit onto both the AL.SK190 and AL.SK350 cranes.
The new jib will have a 3,400t lifting capacity and will be built from specialist steel milled with steel grades up to S1100QL used. The jib is a modular design and can be assembled in different configurations.
As part of the Innovation Series, ALE’s AL.SK190 and AL.SK350 cranes are designed for the lifting and installation of ultra-heavy loads. They can be equipped with a 4,000t main winch system and a 600t auxiliary quick winch system. For weights from 4,000t-5,000t a strand jack lifting system will be utilised.
These cranes can perform lifts previously unachievable, whilst occupying a very small footprint and have the ability to save clients time and money on the construction site by reducing schedule, risk and cost.
Ronald Hoefmans, ALE’s Technical Director, said: “The AL.SK cranes have always been designed with a potential for a jib but 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 be comprised of a unique patented design with a wide strut. It is this special design which will boost the lifting capacity.”
The build is expected to start in March 2016 and complete by the end of the year.
The first contract for the jib involving uplifting modules weighing up to 2,800t to a height of 65m.
