These units feature a clamping arm that retracts to clear the working area for fast part loading and unloading. When actuated, the clamping arm extends approximately 1" out from the front of the clamp before it moves down through 1/4" clamping stroke (automatically compensating for part variation). A spring loaded blade scrapes debris from the top surface of the arm as it retreats. One or more Hydra-Dyne retracting clamps can bring inexpensive, automated clamping to any machine - production line or job shop. These self-contained units can be used over and over again. By choice of valving, they can be actuated simultaneously or sequentially in time to machine operations. Features:
