ABSTRACT:
A handbrake arrangement for a single cylinder, truck-mounted, railway car brake assembly comprising a lever system mounted on the body of the single brake cylinder, which is, in turn, mounted on one of a pair of truck brake beams. The lever system is connected to the handbrake chain, so that operation of the handwheel effects relative movement between the brake cylinder body and brake cylinder push rod. This results in the truck brake beams being spread apart into braking position in the same manner as occurs during a pneumatic brake application, via the respective brake beam, transfer levers and force-transmitting connecting rods that extend between the brake beams.
