One Hudson Ave. The HTR-1A truck restraint is designed to secure an intact and proper ICC bar at the rear of the trailer. Restraint is accomplished by release of device arms that have upper arm and hook integrated as one unit. A gas spring provides an upward bias movement of arms and insures constant contact to the ICC bar. Operating range is from 12 to 30 vertically from grade and a 10 grasping range from the face of a 4 thick bumper.
Restraint is in stored position as trailer is backed against bumpers and brakes are set.
Dock attendant makes a visual check for intact ICC bar. Selector switch on interior control panel is turned to the UP position, releasing the restraint. The gas spring raises the arms until upper arm with hook makes contact with ICC bar. Positive contact with ICC bar turns on the outside red strobe light and inside green light. Storage is accomplished by turning the selector switch to the DOWN position.
