The IYJ hydraulic winch series use the patent technique of our company and consist of a variety of valve blocks with function of braking and single counterbalance valve,high speed hydraulic motor,Z type brake,KC type or GC type planetary gearbox,drum, frame and clutch.The user only needs to provide a hydraulic power pack and directional valve.Due to the winches fitted with diversified valve block,it not only simplified the hydraulic system,but also improved the reliability of the winches. In addition,the winches feature a high efficiency and power,low noise and energy consumption, and have a compact figure and good economic value. Therefore,the series have been widely applied to construction,petroleum,mining geological drilling, ship and deck machinery.IYJ series hydraulic winches have been well sold in China, and also have been exported to the Middle-east,south-east Asia,India,Korea,Russia,Australia,Us,Netherlands and so on.
IYJ334-75-88-22-ZPG represents that the hydraulic winch adopts a three stage planetary gearbox,and that the modules of the gearbox are 3,3 and 4 respectively.The rated single pull on 1st layer is 75KN,drum capacity is 88,rope diameter is 22mm.the winch is fitted with brake,counterbalance valve,and is driven by a high speed axial hydraulic motor.
a.The total displacement represents the oil flow supply per revolution of the drum(mL/r).
b.The oil flow supply indicates the theoretical flow of the pump when the volumetric efficiency is considered to be 90-94%.
c.Maintain mandatory minimum of three wraps rope to be left on the drum at all times for safety.
d.The working pressure differential represents the pressure drop between port A and port B.
e.This winch series can be equipped with a rope roller alarm system for the last three winding ropes,rope-guider output shaft for rotation speed measurement,these items are optional.More options are available please contact the sales department.
5.There are other winch series available,such as IYJ-L free fall hydraulic winch series,IYJ-C hydraulic mooring winch series,ISYJ hydraulic winch series for truck,INYJ internal hydraulic winch series and so on, please refer to other catalogs of our company or contact the sales department.
