Overview
Detachable garbage truck, also known as hook-arm garbage truck, pull-arm garbage truck. The truck is widely used for garbage disposal in urban streets and schools. One truck can be equipped with multiple buckets, and multiple garbage buckets can be placed at each garbage point. It has a self-unloading function and is hydraulically operated for easy dumping. The box part of the car is completely controlled by the hydraulic system. On weekdays, the on-board garbage cans can be placed in various garbage collection stations. After the garbage is fully collected, the car can be directly driven to the garbage station. Put down the hook arm installed on the rear seat of the garbage truck, hang the connection point at the front end of the garbage can in the station, and pull the garbage can to the rear seat of the vehicle body. At this time, the vehicle can be started to transport the garbage to the garbage disposal station. Do a self-dumping dump. The main advantage of the car is that it can be equipped with multiple buckets in one car, and one car can maintain the operation of several garbage collection stations, with high efficiency, and the box body is sealed, which will not cause secondary pollution.

Structure
The truck is composed of chassis, main cylinder of pull arm, attached frame, flip frame, support legs (optional), locking frame, locking oil cylinder and multi-way reversing valve. One end of the flip frame is connected to the attached frame, the other end is provided with a movable pull arm, and a locking system is installed in the middle; one end of the movable arm oil cylinder is connected to the movable arm, and the other end is connected to the attached frame; The action of tightening the oil cylinder can connect the box on the attached frame with the turning frame and the pull arm when the box is self-unloading, forming a self-unloading angle when the main oil cylinder is extended, and can also be turned over by the retraction of the locking oil cylinder. The frame and the attached frame are locked as a whole, and the retractable or extended main oil cylinder enables the movable arm to drag the underground garbage can to the attached frame or put it back to the ground from the attached frame.
The truck can pull the garbage in the underground garbage can and the garbage can to the truck for transport and can also self-unload, which reduces the labor intensity of workers. The collection and transportation method of the garbage truck is the most widely used garbage collection and transportation method in the world. It can realize multiple boxes in one vehicle, greatly reducing the equipment cost and space, etc. The functions of its special devices are powered by the automobile engine and hydraulic The mechanism can be realized manually or electronically. The box body of the vehicle adopts a fully sealed welded structure of high-quality carbon steel plate, which has the advantages of high strength, light weight, and no secondary pollution.

Working principle
Before loading garbage, when the no-load operation reaches 6 standard air pressures, hang up the power take-off (lower left of the steering wheel in the cab), check whether there is any leakage or abnormality of each component, and then operate according to the position indicated by the operation indicator; the specific The operation steps are as follows:
Step 1. Push the locking hook operating handle to the retracted position, retract the locking cylinder, retract the locking frame and lock and fix the flip frame and the attached frame;

Step 2. Pull the operating handle of the pull arm to the extended position, the pull arm oil cylinder is extended, the movable pull arm rotates around the front hinge axis of the flip frame, the pull arm is in the hook box position, and the height of the pull arm hook is properly adjusted and bent with the box body. hook alignment;

Step 3. When the hook of the pulling arm is hooked to the hook of the box body, continue to push the operating handle of the lower arm to the falling position, so that the garbage box body continues to get on the vehicle (Note: Make sure that the longitudinal beam of the garbage box body is located on the two rear rollers at the rear of the attached frame between);

Step 4. After the garbage box is dropped on the attached frame, loosen the operating handle of the pull arm to make it return to the neutral position, then pull up the operating handle of the locking hook to the locking position, and the locking cylinder is extended, so that the The locking frame is turned up and the turning frame is locked and fixed with the garbage box body, and the handle is loosened to make it return to the neutral position;

Step 5. Before unloading the garbage, hook up the power take-off when the vehicle reaches 6 standard air pressures, open the locking device of the rear door of the garbage can, and at the front-stage two-way multi-way valve, first make sure that the locking frame locks the garbage can (Pull up the operating handle of the locking hook to the locking position), then pull up the operating handle of the pulling arm to the extended position, and the garbage box body is ready to tilt and lift the garbage to discharge.
