THE SURFACE CHOCK is designed to secure trucks and trailers, regardless of rear underride guard conditions.
The SURFACE CHOCK is located above grade, allowing it to operate under extreme weather conditions including snow and flooding in driveway wells.
And the SURFACE CHOCK does not require continuous removal of driveway debris or grade excavation for installation, making it ideal for retrofit applications. The SURFACE CHOCK also acts as a guide rail for the reversing truck.

OPERATION
The tough steel construction is designed to withstand impact by a fully loaded truck and to provide a guide rail for backing into the dock position. After the truck is in position, the chock is activated by the dock attendant through the control panel.
The chock moves forward until the sensing roller contacts the rear wheels, activating the SURFACE CHOCK. The chock reverses and secures the rear wheel, clamping the truck or trailer in position. The truck is locked mechanically with a tough steel chock exerting constant hydraulic pressure.
