Adding a fourth sheave to the standard zipSTOP Brake Trolley can assist with stabilizing the Brake Trolley during braking. This is beneficial for zip lines that have lower tension and in installations where the redirection line is not directly overhead. In addition to increased performance it will also extend lifespan of the brake trolley by spreading out braking forces.
