Jacking

Jacking systems including strand jacks provide a cost-effective lifting and pulling solution for the fabrication and load-out of offshore jackets, platforms and modules. Our jacking capacity ranges from 15t to 6,000t.

Our team of specialist engineers saw a gap in the market for a super heavylift jack; and the Mega Jack was designed to assist with the onshore fabrication of increasingly large and heavy topside platforms for the offshore industry, although its versatility means there is great potential for its use in other market sectors as well.

The Mega Jack has both heavy and light jacking modes, and its modular set-up makes it suitable for a wide range of applications. By adding jacking towers, the capacity can be increased or the ground bearing loads per position reduced. A key difference between it and traditional jacking systems is that during normal jacking operations, the jacks remain at ground level and the steel jacking beams rise by each jacking step. This way all operations are performed at ground level and working at height is kept to an absolute minimum.

 

ALE also operates a large inventory of hydraulic climbing jacks up to 1,000t capacity which can be operated in multiple hydraulic circuits for load equalisation.
