Clamps (Series GRM)

-General
Series GRM Clamps are designed specifically for handling sheet metal in stamping/fabricating press applications. A compact size make the Series GRM Clamp ideal for applications in confined work areas.

 

Advantages: Simple design, long life, high clamp force, six modular designed jaw tips are available.


-Benefits
*Simple design, long life, high clamp force, and fast field maintenance make these clamps ideal for sheet metal handling.
*Available in 3 sizes, 9 jaw styles, and 6 jaw openings to fit a wide range of clamping applications.
*Compact envelope size and high clamp force. Series GRM sizes 2 & 3, design 2, generate up to 225 lb [1,000 N] of clamp force. The Series GRM, size 4, design 2 & 6, generates up to 500 lb [2,000 N] of clamp force for maximum flexibility and performance.
*Six modular designed jaw tips are offered for maximum clamping performance in a variety of applications.
*The jaws of the Series GRM, design 2 clamp lock in the closed position ensuring part retention if air pressure is lost due to line rupture or power loss.
*Available with fixed or spherical mounting brackets for side or rear mounting.
*Two adjustable hardened steel impact plates eliminate damage from panel impact.
*Fully field repairable in just 10 minutes, using metric hex wrenches.
*Wide and deep throats accommodate difficult clamping applications.
*Additional mounting, jaw, switch, and tip options are available.

*PHD Clamps are covered under one or more of the following patents: 6,048,013 6,056,281 5,941,513


Additional patents are pending.
