Лебедки морские (корабельные) SEC Bremen

21 MOORING WINCHES The smallest mooring winch produced by SEC has a nominal pull of 10 kN. The maximum size still has to be found. The design principles of a mooring winch are based on the nominal pulling force of the winch. This force depends on the minimum breakload of the applied rope or wire. The rope diameter, length and material of the mooring line determine the diameter and length of the drum. To help increase the lifetime of mooring lines, the SEC Ten Horn mooring winches have a large drum diameter than prescribed by Class societies. The mooring winches are delivered with a split drum when polypropylene is applied. On mooring winches with steel wire the drum will not be split. Both self tensioning and remote control can be easily added to this winch. The table shows the dimensions for one of the mooring winches. This winch has one gearbox, drum and warpinghead. On board of OCIMF-tankers there are additional guidelines and recommendations for the use of mooring winches. We like to give you a short overview: The working part of the split drum must be suited for 10 turns at the drum, in addition the complete wire length must fit on the working part. When steel wire is used, the drum diameter has to be at least 16 times the wire diameter. HIGH QUALITY COMPONENTS • SEAWATER RESISTANT BEARINGS • SPLIT DRUMS POSSIBLE • SELF TENSIONING
