operation
The trailer is backed into position at the loading dock until contacting the dock bumpers. The driver sets the brakes and chocks the wheels.
The dock attendant uses the control bar to activate the restraint barrier that rises until contacting the rear impact guard to secure the trailer.
The barrier provides a restraining force of 32,000 lbs. and will automatically adjust to up and down trailer movement during loading.
When loading or unloading is complete the attendant uses the control bar to lower the restraint to its stored position.
construction
The enclosed barrier and housing design is a structural welded assembly constructed with dual reinforced 1/2” steel restraining arms and 1/4” enclosure panel. The housing protects components from the effects of weather, dirt and debris.
Dual 1/2” steel reinforced vertical tracks are welded securely to the 3/8” wall mounting plate.
All structural components including the mounting plate, track, barrier, and lift arms are two-part zinc dichromate plated for high corrosion resistance.
installation
Every NORDOCK® TRUCK-LOCK® vehicle restraint is factory assembled and tested. The restraint is mounted to the dock face by means of concrete wedge anchors and welding to the pit curb angle.
An alternate method is to weld the restraint to a dock face embedded steel plate.
Total mounting force is in excess of 100,000 lbs. All components are to be installed in accordance with instructions provided in the owner’s manual.
communication
Safety equipment includes inside operating instructions for the dock attendant and an outside mounted sign with forward and reverse lettering for truck driver.
