Abstract
A zipwire trolley having a plurality of zipwire engaging rollers, a swivelable brake block assembly adjacent to one of the rollers, the brake block having a zipwire-engaging cam by which the roller can be at least partially lifted off the zipwire when the trolley is moving in a rearward direction, the cam having a pair of tapered sidewalls tending to pinch respectively opposite sides of the upper part of the zipwire as the brake block progressively rotates when the trolley is moving in a rearward direction, thereby preventing or inhibiting further rearward movement of the trolley.
