EZ-Lock™ Vehicle Restraint

OPERATION

As the railer backs into position, the rear impact guard (RIG) contacts the spring-loaded structural steel housing, which rides down in its track and allows the RIG to move over the top of the housing. Using the supplied handle, the dock attendant pushes down on the restraint pad and applies a slight twist to release the hook from its stored position, allowing the rotating hook to engage the RIG and securely restrain the trailer at the dock. The rotating hook can withstand a pull-away force of over 32,000-pounds. The EZ-Lock™ restraint maintains contact with the RIG and adjusts automatically with trailer float motion to ensure proper engagement at all times. After unloading/loading is complete, the dock attendant uses the handle to push down on the restraint pad, returning the hook to its locked, stored position.

OPTIONAL FEATURES

• Articulated slope extension
• Projection brackets and reinforcing plates
• Manually activated inside and outside signal lights

STRUCTURAL

The rotating hook can withstand a pull-away force of over 32,000-pounds and is machined from 1 1/4-inch thick A514 Grade B steel plate and driven with a 1 1/4-inch diameter shaft made from cold-rolled 1008 steel. The carriage side plates are constructed from abrasion-resistant 200F steel for maximum defense against wear from contact and friction with the RIG. The 1 1/4-inch diameter carriage axles and 2 5/16-inch diameter rollers are both made from cold-rolled 1045 steel. The roller track is formed out of ASTM A572 Grade 50 steel into a 6 3/8 x 3-inch channel with 7/8-inch flanges. The roller track is attached to the dock face with 15 heavy-duty sleeve anchors that each measure 5/8 x 4-inch long.
