Abstract

See full text

The rail clamp includes a carriage having an actuator frame mounted to its base so as to extend upwardly from the base. Springs are mounted in the actuator frame at the upper end of the carnage. An actuator is mounted between the base and the springs. A wheel is mounted on a wheel support. The wheel engages the rail. At least one suspension frame is pivotally mounted to the carriage and at an opposite end, to the wheel support. The actuator operates on the suspension frame so as to elevate the carriage. A pair of clamping levers is pivotally mounted to the base of the carriage. Brake shoes mount on the lower-most ends of the levers. The levers are pivotable so as to clamp their lower-most ends together when their upper ends are moved apart.
