MENAROM P.E.C. S.A.'s winches are diversified from constructive point of view and the below items are mounted on them:

  • Reduction gears - made up from an enclosed welded housing in which the tooth wheels are working in an oil bath for providing a proper oiling and cooling. Oil filling and drain plugs are also provided. To check up the oil level, the reduction gear has an observation hole.
  • Chain wheel (chain slip-lifter) - intended for anchoring operation by using either a bridge-link or a bridgeless chain (DIN 766). It is a solid welded construction, that can be operated by means of a clutch claw or a friction coupling (at Diesel engine winches).
  • Anchor drum  - also used for the anchoring operation by means of a steel cable. In this case, at least three wire turns have to remain for security purposes. As the anchor break out is to be done on the first layer, the right calculation of the cable length is very important.
  • Mooring drum - used for operation when a nylon rope which is stored on a area of the drum called stocking area that is separated from the drum working area by means of an intermediate disk.
  • Warping head - intended for the operation with a nylon rope; for safety operations at least three turns of rope have to remain on drum.
  • Band brakes - provided with metal strips and a lining that is resistant to friction. They can be provided with rods for vertical tightening, but in case there is no enough space for such type of brake, a band brake with horizontal rod can be used. As an option, these brakes can be equipped with a pneumatic cylinder for the remote control operation from the wheel cabin, a system that is intended for the brakes release in emergency cases.
  • Mounting on deck - by using brackets with the base plate welded on deck or supports provided with mounting shoes for the winch mounting on deck by means of screws. The winches can be also mounted on bed plates for an easy transport and mounting on deck.
  • Disengaging chain system - it is an option suitable for those winches provided with chain wheel, in order to avoid the chain blocking.
  • Driving motor - can be of electric, hydraulic, electro-hydraulic or DIESEL type. For electric operation there are used marine electric motors with brakes and protection degree IP56 (TENV – no fan with natural cooling). Their design allows an overload operation for two minutes necessary to break the anchor out. Anti-ex motors are used if the winches are intended for mounting on ships transporting explosive substances. For such winches, the electric
    motors can be of single, two or three speed type. The speed adjustment of hydraulic motor is done from their operating system.
  • Cable spooling device - intended for mooring winches with a big stocking capacity where a proper winding of turns is required.
  • Emergency manual operation - is a manual operating system using a lever and a claw for the anchor lifting when the power system is inoperable.
  • Catch claw system - intended for mooring winches when a warping operation is required to provide a static force greater than the band brake holding force. The system is made up from a claw that is set on deck and the indexing wheel is mounted on one of the drum walls.

The winches are certified by the main classification societies, such as: RNR, GL, BV, LRS, DNV, ABS, etc. with electric, hydraulic, electro-hydraulic or DIESEL operation.
