HSL-Series, Heavy Lifting Strand Jacks

Enerpac strand jacks are powered by electrical or diesel driven hydraulic power packs and controlled by Enerpac’s proprietary SCC-Smart Cylinder Control System to ensure full control of lifting and lowering operations. 

Enerpac continually improves reliability, durability, and safety of their strand acks, making them and industry standard for heavy lifting. 

A strand jack can be considered a linear winch.  In a strand jack, a bundle of steel strands are guided through a main “lifting” jack. 

Above and below the cylinder are anchor systems with wedges that grip the strand bundle simultaneously. Lifting and lowering a load is achieved by hydraulically controlling the main jack and both mini jacks alternately. 

In the case of system pressure loss, the wedges are mechanically closed automatically, holding the suspended load in place. 

Today strand jacks are widely recognized as the most sophisticated heavy lifting solution. They are used all over the world to erect bridges, load out offshore structures, and lift/lower heavy loads where the use of conventional cranes is neither economical or practical.
