operation
As the driver backs the truck into the loading dock, the trailer’s RIG makes contact with the restraint housing, automatically positioning the housing under and firmly against the RIG.
With the truck in position, the driver sets the brakes and chocks the wheels. The dock attendant pushes the lock button, activating and positioning the large rotating hook in front of the RIG, safely securing the trailer to the loading dock.
During loading/unloading, the housing automatically adjusts to the trailer’s movement while the hook positioning sensor monitors the hook and provides constant upward biased pressure against the RIG, preventing hazards such as trailer creep, early departure and/or tip over.
When no RIG is detected, the hook automatically stores away to avoid damage and goes into fault mode, sounding an alarm to alert the dock attendant. Pushing the override button will silence the alarm while the communication lights indicate a caution condition.
Once the loading cycle is complete, the dock attendant stores the hook by pressing the release button, inside and outside lights then signal the driver and dock attendant when it is safe for the truck to leave.
communication
High-visibility red and green inside and outside LED lights with operator instructions on inside control panel cover and outside mounted sign with clear, large, forward, and reverse lettering for drivers.
If power is lost, the inside and outside lights flash to indicate a power loss condition that is maintained until power is restored. An audible alarm and inside red light warns dock attendant when no RIG has been detected.
construction
The enclosed housing design is a structural welded assembly constructed with 5/16” side plates and 1/2” high tensile reinforcement on leading edge to withstand repeated impacts from backing trailers.
The large rotating hook is constructed of 1 1/4” thick steel and is attached to the housing using a superior 1 1/4” diameter shaft. Zinc plated components include mounting plate, track, hook, housing, and brackets. The housing also comes with black and yellow caution markings for improved visibility.
Waterproof IP67 rated hook position sensor for trouble free non-mechanical hook monitoring.
Patented drive system consists of a direct-coupled IP66 waterproof rated high torque DC motor and high efficiency helical gears. Control panel includes a NEMA 12 rated dust tight enclosure with push button controls and LED communication lights on the cover. The power requirement is 120 volts, single phase and 2 amperes.
installation
The vehicle restraint is mounted to the dock face with concrete wall anchors (included) and then welded onto the pit curb angle.
Alternatively, the vehicle restraint can be welded onto a dock face embedded steel plate. Total mounting force is in excess of 100,000 pounds.
Signs, control panel and optional components are installed in accordance with instructions contained within the installation and owner’s manual.
