Pull-Down Clamp
Special Use Clamps
- Three capacities available: 870, 3,900 or 6,300 lbs.
- Use when lateral clamping is desired.
- Generates straight clamping motion and force along with pull-down clamping force.
- Pull-down force is approximately 1/3 of the straight clamping force.
- This clamp is shipped with the jaw shown. The interchangeable jaws can be purchased for use with this clamp.
- Counter hold devices pull the workpiece down when straight clamping force is applied.
NOTE: Flexible SAE porting or manifold mounting options. The straight and pull-down movements are independent of each other.
* Cylinder capacities are listed at 5,000 psi maximum operating pressure. The output force is adjustable by varying the hydraulic system pressure. (Actual force may vary slightly due to friction loss, seal and wiper drag and/or return springs.)
For proper sealing, mating surface must be flat within 0.003 with a maximum 63 µin Ra surface finish.
* Vertical travel should be restricted so that stroke F can not be exceeded.
** Plug not available. Use o-ring to seal manifold port if G clamp port is being used.
