The PC-6000 Model is a premium automatic unit designed to secure a trailer at the loading dock by engaging the wheel with a large steel chock. The chock is stored below grade with free access for snow removal until a trailer is in position at the loading dock. The chock is then activated providing a secure hold on the trailer preventing forward motion, known as trailer creep. Simple controls and clear instructions and signal lights make it easy for the operator to position and release the vehicle restraint. Outside signal lights and signage communicate to the truck driver when it is safe to approach and leave the loading dock. OPERATION The trailer is backed into position at the loading dock until contacting the dock bumpers and the driver sets the brakes. The dock attendant pushes a control button, automatically changing the outside light to red and activating the chock. The chock automatically raises from its stored position and travels until contacting the truck tire, securing the trailer to the loading dock. The restraint control system monitors the position of the chock and provides an inside green light only when the trailer is properly secured. When loading or unloading is completed the dock attendant stores the chock by pushing the release button and the truck is free to leave. At all times, the inside and outside lights indicate the operational mode communication to the truck driver and dock attendant. CONSTRUCTION The solid steel face contoured chock with reinforcement plates is designed for the severe outside environment and forces exerted by the trailer. The housing embed is a welded pan assembly with concrete anchors attached and running surface track constructed with 3/8” structural steel. The entire outside components are primed and painted with a bright safety yellow to assist with truck positioning. The drive system includes a heavy-duty hydraulic cylinder driven by a 3 HP 3 Phase motor pump fed with double braided high-pressure hoses. The reservoir comes oil filled with low temperature and/or biodegradable oil for use in all environments. The control panel includes a NEMA 12 rated dust tight enclosure with push button controls, operator instructions and communication lights on the cover.
