A included angle between a rope and vertical plane of winch drum or warping end axial line, through the point at which rope leaves the drum or warping end

A unit fitted with control levers, buttons, etc., as appropriate.

The most essential characteristic parameters of a machine mechanical performance, indication with some important technical index.

The maximum rope tension (in kilonewtons), measured at the drum exit when the winch is hoisting or hauling in at the nominal speed with the rope wound on the drum in a single layer.

The maximum tension (in kilonewtons) that can be maintained by a braking/locking system in the first layer.

The maximum rope tension (in kilonewtons), measured at the drum exit when the drum ceases to rotate in the direction of haul, the prime mover being set for maximum torque and the rope being wound on the drum in a single layer.

A test applied to the first machine of anew design.

A test applied to each machine produced by a manufacturer.

A test applied to one of a batch of machines of identical design from one manufacturer.

A machine designed to drop and hoist the anchor. It has one or more cable lifters mounted on a horizontal shaft, each being fitted with a brake. The cable lifters are capable of being declutched from the prime mover. One or two warping ends may also be fi ...

A power-driven cable lifter mounted on a vertical shaft. The shaft may be extended beyond the cable lifter to carry a warping end. The cable lifter is declutch-able from the prime mover, and in operation and use is similar to the windlass.

A winch used solely for warping, on which a rope may be wound under power but not stored.

A winch with the ability to hold and haul a tensioned mooring rope and having a capacity for rope storage, controlled solely by hand.

A mooring winch with the additional ability to haul or render a mooring rope within selectable limits without direct human intervention.

A machine with a common prime mover which will provide independently the functions of either a windlass or a mooring winch (automatic or non-automatic).

A machine having a vertically mounted warping end on which a rope may be wound under power, but not stored.

A winch with the ability to drop and hoist the anchor which is tied with a rope or a rope combined with chain and to hold and storage rope may be fixed or not the warping ends

Average speed of recovery two shots of chain cable when three shots are submerged and freely suspended at commencement lifting (m/s)

Maximum speed, maintained by a winch when it is bearing the drum load (m/s)

The maximum rope speed (in meters per second) that the winch can maintain with the rope wound on the drum in a single layer, and with negligible tension on the rope, normally not more than 10% of the drum load.
