20 Tons Dongfeng Hooklift Truck

● Main technical parameters of hooklift system

Hooklift garbage truck is widely used in urban street and school garbage disposal, a truck can be equipped with multiple boxes, each garbage point placed multiple, high efficiency, and the box is sealed design, will not cause secondary pollution, and has the function of self-unloading, wireless remote control operation.

The box part of the hooklift system is completely controlled by the hydraulic system, which can place the vehicle garbage bin to each garbage collection station. 

Main configuration

YT5259ZXXD5 detachable garbage truck is a special environmental sanitation vehicle modified on the basis of the second class chassis of Dongfeng brand truck.

It is composed of chassis, hooklift , drum support stability system, hydraulic system, control system and so on.

Technical features:

A. Advanced structure and hydraulic system design.

B, all operations can be operated remotely (30 meters range), simple and convenient operation.

C, adequate anti-corrosion treatment measures for structural parts: steel components sprayed with high-quality paint; Metal parts (shaft connectors, hard tubing, hose fittings, bolt joints, etc.) are treated with anti-corrosion and galvanized.

D. Integral casting parts are used in many places where the friction between the drawarm hook and the box is relatively concentrated. Casting parts have good mechanical properties and excellent friction and lubrication properties

E. Kinematic characteristics

1) The car can slide a certain distance horizontally on the guide rail

2) Horizontal sliding can be used to effectively reduce the height of the center of gravity in the process of unloading and loading and unloading boxes

3) Can mount a larger length range of the car box, thereby improving the efficiency of vehicle utilization

F, safety device

1) The total pressure of the system and each unit valve block are set with overload protection.

2) Lifting cylinder, sliding cylinder, rear box lock cylinder and rear stabilization device are equipped with load holding valves.

Hydraulic interlocking is provided between functional circuits such as hook arm sliding, box self-unloading, loading and unloading box and rear box locking to avoid misoperation.

3) Hook: high strength design, overall manufacturing. The contact surface curve fits the actual motion trajectory, making it easier and more reliable to hang and unload boxes. The hook is equipped with mechanical gravity safety device to ensure safety and reliability.

Hydraulic system: composed of hydraulic oil pump, main control valve, balance valve, hydraulic lock, tipping cylinder, sliding cylinder, hydraulic tubing, hydraulic oil tank and so on.

Control system: composed of pneumatic control valve, gas pipe, etc. The air control system installed in the cab is equipped with damping device to ensure safe and reliable control action. By controlling the pneumatic control valve, the corresponding hydraulic actuator is controlled to achieve the required action requirements during the operation of the arm hook.

Hydraulic drum rear support system: dual cylinder rear axle stabilization device, drum rear axle stabilizer mounted on the chassis rear overhang, main

The main function is to reduce the rear suspension load of the vehicle girder and prevent the vehicle from cocking its head during the operation of the draw-arm hook.
