Hydraulic winch is widely used in the repair car, it is an important feature, they can be used for lifting and towing tractor(for wrecker tow truck), hydraulic winch from light to heavy have many specifications, the commonly used hydraulic winch has worm gear and worm and planetary gear reduction two kinds of structure, winch driven by hydraulic motor, through the reduction gear to achieve the purpose of the slow down and increase the output torque, so as to realize the relative overloading of capstan drawing ability, worm and worm wheel type hydraulic winch is relatively simple in structure, make easy, transmission efficiency and production costs are relatively low, generally used for MLJ hydraulic winch, and the planetary wheel type hydraulic winch structure is relatively complex, Large transmission ratio, transmission efficiency and production cost is relatively high, generally used in medium and heavy hydraulic capstan.

On the repair car, hydraulic winch used more in the place of installation, and offset the hydraulic winch is gradually applied on some repair car, general repair car installed on one or two winch, according to the needs of design, the winch wire rope can be used both up and down the line direction, in order to better prevent disorderly rope, wire rope on the winch shall be equipped with pressure guide rope device, repair car of the winch and the selection of wire rope and installation is very important, it relates to technology and safety performance of the vehicle, therefore should note: when installing and using

(1) before the installation of the winch to check whether the parts are complete, there is no damage phenomenon, such as parts damage, must be replaced after the installation.

(2)The winch with the connection base or bracket should be mechanical for 10.High strength bolts of grade 9 or above are fixed to ensure adequate bond strength.

(3)After the capstan installation, to check the hydraulic pipeline is wrong, clutch can be normal combination, separation, capstan drum can be normal rotation, can not appear stuck phenomenon.

(4)In winch winding wire rope, the rope head into the drum hole, and then tighten the screw, and in the rewinding condition, winding 4-5 circles, loading 3-5kn force to wire rope wrapped.

(5)Wire rope around and around the drum when the maximum Angle of not more than 3 °, in case the rope and the winch force deflection.In the out of service, the wire rope pressure device will be pressed tight, to prevent loose wire rope and random rope.

(6)After the installation of capstan, in the heavy load test before or long time to use when the idle running, in order to facilitate the smooth running of the motor.

It is strictly prohibited to take off the capstan clutch during the hoisting of heavy weights or pull-up, during the operation of the capstan, the steel wire rope has at least 5 rings on the drum.
Therefore strictly prohibited capstan overload use, in case of damage to the capstan and a safety accident.
