Hydraulic Brake Motor Assembly for Truck Cover System

摘要

A hydraulic brake gear motor with a brake mechanism to operate a roll tarp for use with an open top container of a trailer or rail car. A motor-driven rollable cover is attached to and wrappable about a reel to selectively cover contents of the container. The hydraulic driven gear motor operates with a brake mechanism to lock and hold a position of the motor. A secondary brake mechanism may include a hydraulic piston that selectively engages a holding brake with a hex connector. An efficient transmission having rolling gears can be operated by the hydraulic motor with the brake mechanism. The motor and brake mechanism are preferably hydraulically operated with an existing system of the trailer or rail car.
