winch, mechanical device for hauling or lifting consisting essentially of a movable drum around which a cable is wound so that rotation of the drum produces a drawing force at the end of the cable. A windlass is essentially the same device as a winch, except that a winch may be power-driven whereas a windlass is usually hand-powered and somewhat less sophisticated. Winches are normally equipped with a ratchet wheel and a pawl to prevent slippage of the load, and brakes that allow a load to be lowered or released at a controlled rate. A hoist is another closely related device, mounted so as to be movable (as in a traveling crane). Winches and hoists are widely used in cargo handling, e.g., in ships, factories, and warehouses, and also function as the power unit in derricks, power cranes, and power shovels. A car puller is a winch with a vertical drum axis, used to position railroad cars in freight yards. Certain military and construction vehicles designed for off-road use are equipped with engine-powered winches that can be used for lifting and hauling or to extricate the vehicle should it become stuck in areas where traction is poor. winch 1. a windlass driven by a hand- or power-operated crank 2. a hand- or power-operated crank by which a machine is driven How to thank TFD for its existence?

| Without saying a word she took hold of the winch (it was turned by handpower then), and round she swung him, and Jack began to flop about inside. Against their lurid background dark figures were bending and straining, twisting and turning, with the motion of winch or of windlass, to the rhythm of an eternal clank and roar. Billy could hear them throwing down the halyards, casting off gaskets, and heaving the anchor short on the tiny winch. |
