Embodiment Construction

[0027] The figures show a winch configured as an anchor winch 10 . Usually at least one such anchor winch is arranged on the deck of a large commercial ship, in particular a marine ship, such as a container carrier, a packed container carrier, a cruise ship, a ferry, a cruising ship, a tugboat or the like. An anchor winch 10 is used to pay out and winch the anchor with its chain. Anchor and anchor chain are not shown in the figure.

[0028]In the region of the anchor winch 10 the anchor chain is laid around a part, for example one third to two thirds, of the sprocket 11 of the anchor winch 10 . In this case, several adjacent chain links of the anchor chain are partially located in the chain link receptacles 12 of the sprocket 11 . The chain link receptacle 12 is arranged on the periphery of the peripheral surface of the sprocket 11 and thus serves to couple the anchor chain in a form-locking manner and to drive the anchor chain with the rotationally driven sprocket 11 .

Abstract

Anchor winches (10) are used to lower and haul in anchors together with the anchor chains thereof. The anchor winches (10) have a drive, by means of which at least the hauling in of the anchor together with the anchor chain occurs in a motorized manner. Under unfavorable conditions, the power of the drive may be insufficient to haul in the anchor. Then there is the risk that the anchor chain is pulled from the anchor winch (10), which in the worst case leads to the loss of the anchor. The aim of the invention is to avoid the described disadvantages. This aim is achieved by an anchor winch (10), the band brake (15) of which can be manually actuated according to a first actuation mode and, in an emergency, can be automatically actuated by means of a second actuation mode, for example by means of a hydraulic cylinder (28) that can be actuated by a control system. The hydraulic cylinder (28) operates the actuating device (21) of the band brake (15) in an emergency in order to thus virtually initiate an "emergency stop", which eliminates the risk of the anchor chain being unintentionally pulled from the anchor winch (10) under high loads.

Description

technical field [0001] The invention relates to a method for operating deck equipment on a ship according to the preamble of claim 1 and a winch for deck equipment according to the preamble of claim 5 . Background technique [0002] The ship's deck equipment includes, inter alia, anchors with anchor chains, cables, such as towing cables, and fixed lines. Especially in large sea vessels such as container carriers, ferries and cruise ships, winches are used to at least winch or winch and preferably also to pay out anchors and their chains as well as cables and fixing lines. For anchor chains, anchor winches are used with so-called sprockets for form-fitting engagement into several chain links of the anchor chain. For cables and fixed ropes, winches are used. The winch has a drum with an inwardly arched peripheral surface around which the cable or fixing rope is wound several times for causing a corresponding friction lock between the winch drum and the cable or fixing rope w...
