Abstract
A continuous assist braking and control system (10) operable to control the movement, speed and acceleration of a zipline rider (32) traversing a zipline (12). A brake line (40) is entrained around first and second reels (50, 52), and suspended above the zipline (12). The rider (32) is tethered to the brake line (40). A brake (56) is coupled to at least one of the reels (50, 52). When the brake (56) is disengaged, the brake line (40) is pulled along with the rider (32) as the rider (32) traverses the zipline 12). When the brake (56) is engaged, the reels' rate of rotation is slowed, thereby slowing the brake line (40) and the rider (32). When the brake (56) is engaged to stop the reels' rotation, the brake line (40) is brought to a stop, thereby arresting the motion of rider (32).
