Zipline Brake Systems
Ziplines can still have a good deal of speed by the time they reach the end. A braking mechanism is necessary to slow the rider down.
There are several good ways to do this. One method uses the brake block. This device slides on the cable. The cable runs through a hole through the block. The brake block has a bungee attached to it, which is either fastened to the ground, trees, or to a person on the ground operating the brake. Another method uses a compression spring. The spring is threaded onto the cable before anchoring to each end. When the pully hits the compression spring the velocity is slowed. This type of brake works well for shorter backyard ziplines.
