Hydraulic Power Pack GripControl

Gentle clamping with GripControl hydraulic power packs

  • GripControl hydraulic power-packs are tailor-made for ZwickRoell hydraulic grips and tools/fixtures up to 250 kN.
  • All power packs feature a high degree of safety, including Emergency STOP chain and inching mode. 
  • Space-saving design enables the power pack to fit under the table. Extremely high availability, maintenance-friendly design, and long service life are stand-out features of these power packs.

Significant Advantages and Features

Perfect, Gentle Clamping

Specimens are always gripped and held perfectly, regardless of the properties of the specimen material.

  • Various operating modes can be selected such as optional continuous gripping, re-tightening in the event of a pressure drop, or wedge gripping with a pressure proportional to the current test load.
  • Operation is possible even at very low pressures.
  • Specimen grip closing speed optionally adjustable via testXpert III.
  • ZwickRoell's automatic force zero control reliably protects the specimen from unwanted tensile or compression forces due to material flow or grip deformation during the closing and gripping process.

Safety

Operator safety is guaranteed at all times, for example by integration into the Emergency STOP circuit and inching mode.

EtherCAT Interface

The hydraulic power pack is directly connected to the testControl machine electronics. This offers several advantages during the specimen insertion process and the test. The power pack is linked to testControl II via the EtherCAT interface, which is compatible with future generations, leaving the interface modules of the machine electronics available.

Ergonomic Control

All power pack functions can be controlled conveniently and ergonomically via the testing software or the machine remote control. This offers numerous advantages during the gripping process and the test.

Intelligent Changeover

Changing between different tests is a breeze thanks to testXpert III's System Configuration Builder. This includes automatic test-specific storage of test parameters and the test environment.

GripControl for Short Clamping Lengths

The perfect synergy between short-clamping-length grips and GripControl allows optimum gripping of even the smallest, most sensitive specimens.

Additional Benefits of GripControl Stand Alone

  • The stand-alone power pack is controlled directly by its own remote control with no connection to the testControl electronics. The remote control features the following functions:
  • Grips can be opened or closed individually.
  • Pressure can be set very simply via a dial control.
  • Re-tightening function can also be activated via the remote control.
  • Short cycle times, easy to operate. Two different pumps ensure rapid closing and high pressures. Smooth, fully automatic switching.
