ABSTRACT:
An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable (8) as seen in FIGS.1A and1B. The trolley comprises front and rear pulleys (44F) and (44R) conjoined via pulley housing (16) with left and right horizontal handles (10L) and (10R) attached to vertical shaft (12). Front and rear hand brake levers (20F) and (20R) are mounted onto left and right horizontal handles (10L) and (10R). When front and rear hand brake levers (20F) and (20R) are squeezed by the rider, they create a constricting force on front left and right calipers (32FL) and (32FR) along with rear left and right calipers (32RL) and (32RR) of FIGS.2A and3A. Thus, friction is applied to front and rear pulleys (44F) and (44R) via front left and right brake pads (34FL) and (34FR) along with rear left and right brake pads (34RL) and (34RR). This frictional force slows the rider's speed to his or her desired rate and brings the rider to a safe stop at a precise location along suspended cable (8).
