Pneumatic Wedge Action Grip Accessories

Mounting hardware and adapters can be added to pneumatic wedge action grips. Mounting hardware provides the interface between the grips and the load frame while adapters can be added to increase the range of testing functionality. 

By simply choosing the appropriate adapter, auxiliary fixtures can be mounted to the main grip body. This makes it possible to carry out other modes of testing without the need to remove large capacity grips. This convenience allows all testing to be carried out in one test area at one working test height - saving on setup time.

Principle Of Operation

Mounting hardware includes two threaded studs and two self-locking taper washers. This hardware connects the pneumatic wedge grips to the load frame and ensures that the grips don't rotate or move during a test.

Piggyback adapters are easily mounted on all pneumatic wedge grips to allow lower force grips to be used. Positive mechanical location ensures secure mounting and ease of use. 

A compression accessory kit can be added to W-5180 and W-5190. This kit includes four retainer plates that are fixed to the main grip bodies without compromising tension testing capability. These retainers provide a convenient attachment point for two adapter platens, which are inserted to perform compression testing. The compression adapter platens include locating pins and setscrews to ensure correct alignment and provide the following standard mounting patterns for compression accessories: 

  • (6) x M10 taps on 100 mm point circle diameter 
  • 0.5 in universal mounting with retainer screw

Application Range

  • Wedge action grips 
  • Tension grips for shoulder and threaded specimens 
  • Fastener grips 
  • Compression anvils / platens 
  • 3 and 4 point bend fixture
