BRAKING SYSTEM FOR TRANSPORTATION DEVICE

摘要

A braking system (44) for a transportation device (10) having at least one castor assembly (22, 24, 26, 28) rotatably mounted on the transportation device, which castor assembly is provided with a wheel (38) rotatably mounted within the castor assembly, which braking system comprises: a braking mechanism for restricting rotatable movement of the castor assembly with respect to the transportation device; a braking element for restricting rotatable movement of the wheel with respect to the castor assembly; and an actuator for actuating the braking mechanism and the braking element; the arrangement being such that actuation of the actuator causes activation of the braking mechanism and of the braking element.
