Abstract: An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable. The trolley comprises front and back wheels conjoined via left and right trolley plates and a handle bar. Front and back hand brake levers are mounted onto the handle bar. When front and back hand brake levers are squeezed by the rider, they create a constricting force which applies friction to the suspended cable via brake pads. 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 the suspended cable. The rider is able to quickly and easily remove the trolley from the suspended cable and transport it to another.

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 and 1B. 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 and 3A. 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).
