Functional Requirements For Truck Mounted Crane

  General truck mounted crane   have the following functional requirements: 1. The crane can be easily transferred with the truck, meeting the requirements of mobility, flexibility and no need for power supply in field operations. 2. The outrigger mechanism can lift the whole vehicle when the truck-mounted hoisting and transport vehicle is carrying out the lifting operation, so that all the tires of the car are off the ground, free from the direct operation of the lifting load, and the supporting state of the hydraulic outriggers can last for a long time. Keep the position unchanged to prevent soft legs when lifting heavy objects. 3. The length and depression angle of the boom can be adjusted, balanced and locked arbitrarily within a certain range to meet the requirements of different lifting operations. 4. The jib of the truck-mounted hoisting and transporter can be rotated and locked arbitrarily within 360 degrees. 5. The   truck-mounted hoisting truck   can lift t...

Installation and use of the winch on wrecker truck

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 mo...
