Revolving clamp break-out bench

Tool for unscrewing hydraulic cylinders

Revolving clamp break-out bench

The tool, part of the drilling accessories product range, is a bench vise for rod unscrewing used in workshops to handle tightening and loosening of large objects such as down-the-hole hammers. It is also essential for the maintenance and repair of hydraulic cylinders, allowing for tightening and rotating large threaded parts as needed.

Key features include:

  • Hardened sliding guides
  • Dual rail for perfect 30° rotation (tightening/loosening)
  • Greasable at any point
  • Bolted components for interchangeability
  • Ability to separate the rod unscrewing function from the clamping function
  • Drawer for storing tools and objects
  • Customizable control unit
  • Includes 4 vises: 2 hydraulic and 2 manual

Bench vise BM305

The BM305 vice installed on the bench consists of a clamping part and another part that performs clamping and unscrewing functions. These two parts can be moved apart manually by loosening the bolts underneath the guide, or hydraulically by operating a control lever.

The BM305 bench vise is available in two versions:

Bench vise with manual adjustment

Hydraulic bench vise
