Abstract
A trolley for traveling along a cable. The trolley may include a frame having a first end, a second end, and a rail positioned between the first and second ends. A brake pad may connect to the frame. A sheave mount may also connect to the frame and include a sheave for rolling along the cable. A carriage may connect to the frame and include a user mount for suspending a user. The carriage may selectively travel along the rail through a continuous range of motion to control a braking force generated by the trolley between the brake pad and the cable.
Claims18
A trolley for traveling along a cable, the trolley comprising:
- a frame having a first end, a second end, a rail positioned between the first and second ends;
- a brake pad connecting to the frame;
- a sheave mount connecting to the frame and having a sheave;
- a carriage having a user mount and selectively traveling along the rail through a continuous range of motion to control a braking force generated by the trolley;
- and
- a tether connected to the carriage and positioned to convert a tensile load applied thereto into a force urging the carriage substantially exclusively in a direction parallel to the rail.

A system comprising:
- a cable held in suspension;
- a trolley comprising a frame, a brake pad connected to the frame and positioned to contact the cable, a sheave connected to the frame and positioned to roll along the cable;
- the trolley having the frame, sheave, and brake pad positioned to provide a frictional force between the brake pad and the cable in response to a moment of force applied to the frame;
- the trolley further comprising a carriage providing a user mount and selectively traveling along the frame through a continuous range of motion to control the moment of force;
- and
- the trolley further comprising a carriage control connected to the carriage and positioned to convert a tensile load applied thereto into a force urging travel of the carriage in a direction corresponding to a reduction in the moment of force.
