Description
The PIT-HOOK Series recessed vehicle restraint improves safety with strength, convenience and reliability.
The PH-3000 Model is a premium automatic hydraulic powered unit designed to secure a truck at the loading dock by engaging the rear impact guard with a large hook.
The restraining hook is stored back of the building face and clear of incoming trucks within a pit cavity below the dock leveler, away from weather and debris.
The unique reach and grab aspect of the hook leaves no gap between the hook and the trailer, essentially eliminating trailer creep and preventing landing gear collapse.
The exclusive HYDRA-FLOAT hook automatically adjusts to various heights of trucks and maintains position during loading.
The operator easily activates and stores the restraining hook with the push of a button.
The hook reaches out from the stored position and holds rear impact guards as low as 9” high and rises to 30” while extending 14” horizontally to restrain all types of trailers.
Operation
With the exterior signal light showing green the trailer is backed into position at the loading dock until contacting the dock bumpers.
The inside light shows red until the dock attendant pushes a control button that activates the restraining hook.
The exterior signal light immediately changes to red as the hook automatically advances through its cycle until the trailer is secured.
When the hook makes positive engagement with the trailers rear impact guard the inside light will turn to green and the interlock system will allow operation of the dock leveler.
In the event a secure engagement of the trailer does not occur, an alarm will alert the operator to the fault condition.
Alternate safety procedures are required and an override control when actuated will allow operation of the dock leveler.
The hook will provide a restraining force in excess of 35,000 lbs. and will automatically adjust with trailer float during loading and unloading operations assuring the trailer is restrained at all times.
When loading or unloading is completed the dock attendant stores the restraint by pushing the release button.
The inside light immediately changes to red after the hook is fully retracted the outside light turns green signally it is safe for the trailer to leave.
