Featuring NORDOCK® patented Direct Drive System with exclusive Hook Position Sensor.
The SMART-HOOK® Series of automatic vehicle restraint is designed to prevent unscheduled departure, trailer creep and tip overs by using a large rotating hook to secure a trailer's rear impact guard (RIG) to the loading dock with 32,000 lbs. of restraining force and a mounting force in excess of 100,000 lbs.
The improved AR-9500 features an updated direct drive system that eliminates the use of failure prone mechanical limit switches, replacing them with an exclusive watertight Hook Position Sensor and Solid State Control System with diagnostics that tracks and monitors the rotating hooks position.
The low profile housing automatically adjusts to various trailer heights and movement and lowers to 9" above grade, avoiding potential damage from low hanging rear impact guards.
The restraint is stored above ground level to keep free of snow, ice and debris.
AR-9500 Features & Benefits
AR-9500 Optional Equipment
The SMART-HOOK® Series of vehicle restraints improve safety along with strength, convenience and long term reliability.
The AR-9500 Model is a premium automatic unit designed to secure a truck at the loading dock by engaging the rear impact guard with a large rotating hook.
The housing is stored above ground, keeping it free of snow, ice and debris, and automatically adjusts to the various heights of trucks and maintains position with the rear impact guard during loading.
The operator easily activates and stores the barrier with a push of a button.
The low profile housing lowers to only 9" high to escape damage from low rear impact guards, and will secure standard trailers with 32,000 pounds of restraining force.
The trailer is backed into position at the loading dock contacting the housing of the restraint and positioning it automatically underneath the rear impact guard.
The driver sets the brakes and chocks the wheels.
The dock attendant pushes a control button, activating the hook that rotates in front of the rear impact guard until it secures the trailer to the loading dock.
The restraint monitors the position of the hook and provides constant upward biased pressure and if the rear impact guard is not detected, will store the hook for protection and sound an alarm.
Pushing an override button will silence the alarm and the lights will indicate a caution condition.
The barrier will adjust to the movement of the rear impact guard during loading and unloading ensuring that the trailer is restrained at all times.
When loading or unloading is completed the dock attendant stores the hook by pushing the release button and the truck is free to leave.
Inside and outside lights communicate all the operational modes to the truck driver as well as the dock attendant.
Safety equipment includes red or green inside and outside lights with operating instructions for the dock attendant, and outside mounted sign with forward and reverse lettering for truck driver. An audible alarm and inside red light warns the dock attendant that a rear impact guard has not been detected.
The enclosed housing design is a structural welded assembly constructed with 5/16" reinforced steel designed for the impact of backing trailers.
The housing protects components from the affects of weather, dirt and debris.
The large rotating steel hook is constructed with 1 1/4" thick steel and attached to the housing with a superior shaft of 1 1/4" diameter.
