Trippers are widely used to deliver material from a yard or wharf conveyor to a stacker or shiploader. The design of the tripper should be integrated with the design of the yard or wharf conveyor because the optimum tripper profile depends on the belt tensions. The lift radius of the belt should be calculated at the head and tail ends of the yard conveyor for full, empty, start and stop conditions. Trippers should be profiled with a convex "buffer curve" near the toe to prevent edge buckling of the belt which results in spillage.
