Hollow Ram Jacks

Hydraulic Jacking

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 hydraulic ram jacks with varying cylinder capacities, available from 27Te – 58.7Te. They are available as single-acting, with a spring return, or double acting. The range is intended for use with a threaded bar system, such as DYWIDAG or Macalloy.

These jacks can be used in conjunction with our range of propping systems. 

All our hydraulic hollow ram jacks are tested, certified and calibrated by our in-house hydraulics experts before every hire. If required, our hydraulics team will also install and operate the jacks for your project. 

Applications:

  • Bridge Jacking
  • Building Refurbishment
  • Lifting/ lowering and sliding
  • Monitoring and control

  • 27Te – 58.7Te cylinder capacity
