PowerHold® Series Automatic Restraint

Loading Dock Truck Restraint


The PowerHold® is a non-impact, self-aligning, hydraulic vehicle restraint system. Once activated, PowerHold® seeks and finds a truck’s “Rear Impact Guard” (RIG), then applies continuous pressure to firmly restrain the vehicle. By applying constant pressure on the RIG, PowerHold® removes dangerous gaps, and eliminates “trailer creep” and potential loss of leveler lip purchase.


The PowerHold® has been tested to withstand up to 32,000 lbs. of pull-out force and has a service range of 0” to 10” horizontally from the face of the dock bumpers and 10” minimum to 27” vertically above drive approach. Powerhold’s® hydraulic design eliminates the need for costly maintenance and adjustment of mechanical components.


Now installed with   iDock Controls

Combination Pump and Motor Option

The PowerHold® can be combined with a Poweramp® VH or PR dock leveler and run off of the same pump and motor as the leveler therefore reducing maintenance and electrical costs.

Push Button Activation

Momentary pressure on the restrain button activates the PowerHold® to automatically engage the truck's rear impact guard.

Non-Impact Design

The PowerHold® remains inside its protective housing until the restraint button is pressed protecting it from damage when either the wall or drive approach mounted.

Positive Restraining Force

The PowerHold's® constant pressure on the truck's rear impact guard removes all gap between the truck and the restraint allowing no room for a head start and maintaining leveler lip purchase on the bed of the truck.

Equipment Interlocking Option

The PowerHold® can be easily interlocked to any powered dock leveler forcing operators to use the restraint before the dock leveler can be positioned onto the truck.

Corrosion Resistant Zinc Plated Finish

The PowerHold® restraint arm is zinc plated to protect it from the elements.
