Trim controlled, dynamically controllable, trolley brake

A method of controlling a descent of a user, the method comprising:

• providing a frame having a first end, a second end, a rail extending from proximate the first end to proximate the second end, and a fulcrum spaced away from the first end toward the second end;
• providing a brake, comprising a first pad, connecting to the frame;
• providing a trimmer, having a second pad, positioned opposite the first pad;
• the providing a trimmer, wherein the trimmer is selectively adjustable by a user riding the trolley to provide a substantially continual clamping force by the first pad against the cable;
• providing a sheave mount connecting a sheave, rolling along the cable, to the fulcrum;
• providing a carriage having a user mount and selectively traveling along the rail;
• the providing a carriage, wherein the carriage is selectively positionable along the rail by the user;
• providing a tether connecting from the carriage to the frame to selectively shift the weight of a user between the carriage and the frame;
• the providing a brake, wherein the brake is dynamically controllable by a user, arbitrarily, by selectively moving the carriage toward the fulcrum, by distributing the effective weight of the user between the carriage directly and the tether;
• selecting a first cable suspended between at least two points;
• connecting the trolley to travel along the cable;
• halting the trolley by setting the trimmer to brake the trolley with respect to the cable;
• suspending a user from the carriage;
• releasing the trolley to roll along the first cable, by re-adjusting the trimmer;
• and
• dynamically braking the trolley by shifting at least a portion of the weight of a user from the carriage to the tether.

A method comprising:

• selecting a trolley supportable by catenaries held in suspension, the trolley comprising
• a frame having first and second ends,
• a fulcrum therebetween,
• at least one sheave connected to support the frame proximate the fulcrum,
• a sheave mount selectively openable to connect the at least one sheave on the cable,
• a brake comprising a pad positioned proximate the first end, and
• a carriage operable to travel along the frame at least a portion of the distance between the second end and the fulcrum;
• connecting the at least one sheave onto a first cable;
• trimming the brake to render the trolley stationary with respect to the first cable;
• suspending a user from the carriage;
• trimming the brake to release the trolley to travel along the first cable;
• controlling the speed of the travel, during the travel, by the user dynamically adjusting the brake;
• the dynamically adjusting the brake, by the user during travel along the first cable;
• opening the sheave mount, by the user;
• and
• removing the trolley from the first cable, by the user.
