DLB 800 lb Dutton-Lainson Brake Winch is used on Demco and Dock Shuttle Dock Side Lifts. Dutton-Lainson Brake Winches are ideal for PWC lifts and davits. Brake winches are self-locking, which provides safety because the winch will not “free-spool”. The automatic friction brake provides a constant positive holding action and prevents a runaway load. The brake is fully automatic and the load remains in position. Many of the same design features as popular D-L trailer winches, but with some important differences. These winches can be used for vertical lifting, whereas trailer winches are for horizontal pulling only. Does not have a ratchet, so they’re always “in gear”. There is no neutral, or free-wheel mode. Friction braking system built into the winch that is always locked in place any time that the handle is released.
