The IYJ-L series hydraulic winch consists of a planetary gearbox, hydraulic motor, wet type brake, various valve blocks of single counterbalance valve and shuttle valve, drum, frame, and hydraulic control Dutch. So, the series not only simplified hydraulic system design, but also improved reliability and durability. The series could get two-speed control if fitted with a variable displacement two-speed hydraulic motor. When fitted with a hydraulic axial piston motor, the working pressure and drive power of the series could be greatly improved.
The IYJ-L series hydraulic winch features smooth performance in hoisting and lowering. The final stage of the series is fitted with a hydraulic clutch (invention patent of our company) to get a free fall function. The winch series has a long life, compact design, and good economy. Therefore, the series has been widely applied in pipe-laying machines, crawler
Options Example:IGY3400L2-B47-21/10 represents that the drive has an output torque of 3400Nm, two-stage planetary gearbox for wheel drives with a total ratio of 47, fitted with a multi-disc parking (two speed) of 21ml/rev in low-speed position and 10ml/rev in high-speed position. brake, and high speed axial hydraulic motor. The hydraulic motor has a variable displacement.
