hydraulic winchThe drum is designed for a capacity to take the wire rope on max 5 layersSteel wire rope is non-rotating type and is galvanized.Winch gear with hydraulic operated fail safe brake

Hydraulic oil cylinderThe luffing cylinder is a double effect single piston cylinder. Chromate treatmentand buffing are carried out for the surface of piston rod. So it has high solidness androughness, and it can prevent from rusting.The telescopic oil cylinder is double-acting piston rod, cylinder is made withseamless steel tube. Cylindrical piston rod chromium plating and polishing on thesurface, hardness and roughness are very high, and can prevent rust

The Hydraulic oil pump unit consists of marine electric motor, pump, coupling, etc. The motor has a protection class of IP56 and insulation class of grade F. The coupling can compensate axial errors between pump and electric motor to prevent the pump from damage. The oil suction pipes should be kept sealed for preventing noise.The  power unit provides the hydraulic oil for the hydraulic system of the crane. The oil lever gauge, air breathe and return filter are mounted on the oil tank
