Abstract
The present disclosure relates to a brake mechanism, particularly useful on a vehicle which travels on the upper side wall edges of gondola cars. The brake mechanism includes a brake shoe rack which carries two pairs of brake shoes, one pair of brake shoes being adapted to clamp one side wall of the gondola car and the other pair of brake shoes being adapted to clamp the other side wall of the gondola car. The pairs of brake shoes are moved in opposition to one another by a single hydraulic ram to effect the clamping of the side walls. The brake shoe rack is pivotally supported below the chassis of the gondola car loader by hydraulic cylinders for raising and lowering the brake shoe rack as the vehicle is moved from gondola car to adjacent gondola car. The brake shoe rack is also movable from side to side with respect to the chassis of the vehicle to enable the brake mechanism to accommodate gondola car side walls which are bowed or otherwise irregularly shaped.
