Mooring Winches .

IYJ-C hydraulic mooring winches: valve block with brake and overload protection, hydraulic motor, enclosed planetary gearbox, band brake, dog clutch, drum, warping head and frame. An enclosed gearbox instead of open gearing and rolling instead of plain bearings raise efficiency by 6–10 % and remove daily lubrication. Comply with GB 4446-84; a constant-tension valve block adds CT function. Standard range IYJ45-C … IYJ79-C: drum load 50–400 kN, holding load 150–1,080 kN, speed 10–15 m/min (light line 20–30 m/min, creep 0.5 m/min), rope 20–50 mm; special versions up to 750 kN.
