The winch is made upof the import hydraulic motor , import balancing valve , the brake of many pieces , coupling , reel , supporting axle and rack . Also we may design the valve group for the distributor of the motor , like with balancing valve , high-pressured shuttle valve , velocity modulation cross valve or other performance valve groups. The characteristic of the construction pact , small , light , beautiful and soon, the characteristic of the performance is safe , the high efficiency , the big start torque , the best low-speed stability characteristic , the low noise , the reliable operation. The winch is quite steadily in the work of promotion and relaxation , The winch with the coupling also may release the things free , It is popular to the railroad otive , the auto hoist , the ships , the oil field of drills picks , the geological prospecting , the coal mine , the harbor and the each kind of hoisting equipment.
