Jacking

Hollow Ram Jacks

Hollow ram jacks are used to support, lift and lower heavy workpieces.

Our Hollow Ram Jacks allow both push and pull forces, enabling fast ram retraction - making it ideal for hydraulic sliding, lifting and lowering heavy structures or containers on site. We offer a range of hollow hyraulic ram jacks with varying cylinder capacities, available from 33 to 59 tonnes. 

Our hollow hydraulic jacks are available as single-acting, with a spring return, or double acting. The range is intended for use with a treaded bar system, such as DYWIDAG.
