The Enerpac WPTL300V is a Collet-Lok swing clamp: the plunger swings 90° counterclockwise onto the part, clamps, and a collet then mechanically locks the 8,500 lb clamping force. Because the lock is mechanical, the fixture can be depressurized or disconnected after clamping and the part stays held, an extra level of safety for pallet and fixture work.
Features
- Double-acting Collet-Lok action for fully automated operation
- Live hydraulics not required to maintain clamping force
- 3.125-16 UN threaded body; can also be flange-mounted
- Viton seals standard
- Uses clamp arm CA-3070 (sold separately)
Sizing
Clamp stroke is 0.39 in within a total stroke of 1.65 in. Effective area is 2.05 in² clamping and 3.45 in² unclamping; oil required is 3.40 in³ to clamp and 5.70 in³ to unclamp. Maximum oil flow is 600 in³/min. Length is 10.57 in retracted and 12.22 in extended.
Before you order: Collet-Lok needs at least 1,400 psi and separate valves for the clamp/unclamp and lock/unlock functions; follow Enerpac's Collet-Lok sequence. Keep oil flow at or below 600 in³/min. For a non-rotating version, Enerpac replaces the L with N in the model number.
