Operation

Regardless of what model you require, the ATL series of automatic vehicle restraints have been designed for safe, easy operation.

ATL-400

Guided by a green outside light, the trailer is backed into position until it contacts the dock bumpers, before the truck’s brakes are set and wheels chocked. The dock attendant can then push a control button to activate the barrier until it contacts the RIG and the trailer is secure.

The outside light will then switch to red while the inside light will now be green. After a proper hitch is confirmed by the dock attendant, a dock leveller can now be used, provided the recommended interconnect has been utilised.

Applying a restraining force of over 32,000lbs., the barrier is designed to float during loading, keeping the trailer always secured.

Following completion of the loading/unloading process, the barrier can then be released and stored by the dock attendant, while the outside light changes to green to advise the driver it is safe to leave the loading dock.

ATL-450

After backing trailer into position until it contacts the dock bumpers, the driver must set vehicle brakes and chock the wheels. The barrier can then be activated by the dock attendant, rising in the vertical track to contact the RIG and secure trailer to the loading dock.

Dock leveller operation can be bypassed using the override selector button while the external signal light remains red.

During loading/unloading, the barrier will provide a restraining force in excess of 32,000lbs and automatically adjust to the trailer’s position as it moves.

Once the loading/unloading process has been completed, the dock attendant can store the barrier using the release button.

Communication

Clear, two-way communication between the driver and dock attendant is vital during the loading and unloading process. The ATL series facilitates this with flashing red or green exterior and interior lights, operator instructions and outside mounted signage with forward and reverse lettering as standard.

Construction

The structurally welded enclosed barrier and housing is constructed of dual reinforced ½” and ¼” steel, protecting working components from the weather and external debris.

Primary components including the 3/8” wall mounting plate, track, barrier and lift arms are zinc plated for enhanced durability.

The dust-proof NEMA 12 control panel is designed to be robust and functional, featuring push button controls, operator instructions and communication lights on the cover.

Installation

Installation of the ATL series of vehicle restraints is designed to be straight forward and efficient. After being mounted to the dock face and pit floor with concrete wedge anchors, the restraint can be welded to the pit curb angle.

Alternatively, the restraint can be welded to a dock face embedded steel plate, with total mounting force exceeding 100,000lbs.

Optional components, signs and control panel are installed in accordance with the instructions detailed in the owner’s manual.

Technical Details

Power requirement is 120VAC, 3 amps.
