Self-unloading semi-trailer is an automatic unloading semi-trailer, suitable for the transport of scattered bulk goods, can effectively load, unload and transport goods, with great strength, strong lifting force, stiffness, toughness, strong bearing capacity and other characteristics. The operation of the self-discharging semi-trailer is usually to lift the carriage, pull out the rod connecting the position of the semi-trailer and the front, and the main car can be opened forward. When operating, we should pay attention to the unloading at the appropriate position and keep a safe distance. Let's learn how to operate the dump semi trailer together with Custom semi trailer manufacturers.
First, the characteristics of the dump semi trailer
1. The carriage adopts the rollover and backflip self-dumping method, which can effectively load, unload and transport the scattered bulk goods.
2, frame and carriage rail are made of high quality manganese plate welding, dustpan and rectangular box two kinds, with great strength, strong lifting force, stiffness, toughness, strong bearing capacity, no permanent deformation.
3. The main components are processed by advanced equipment, and the longitudinal beam is made by automatic submerged arc welding. The assembly machine is used for accurate assembly of axle and steel springs, with excellent technology.
Two, how to operate the dump semi trailer
The name of the dump semi truck is because it can automatically unload, so how to operate the dump semi truck?
Commonly speaking, the dump semi trailer carriage has its own bracket. First use the bracket to support the car, the car and the main car connection position has a pull rod, pull the pull rod, the main car can be removed from the car forward, the specific operation is:
1. Lift the cargo car and dump the load
(1) Stop the vehicle, pull the handbrake (with the back door manual locking mechanism should be first opened the locking mechanism), step down the clutch pedal and wait for about 5 seconds.
(2) Rotate the neutral switch to the horizontal position.
(3) Press the force-retractor warping switch on the instrument panel.
(4) Put the transmission in low forward gear (first or second gear), and control the engine speed at 1000 ~ 1500 RPM.
(5) Gently lift the control valve handle, make it out of the limit groove, move to the "up" position.
(6) Step down the accelerator pedal, slowly release the clutch pedal, the cargo car can rise. When the cargo car rises to a steep position, automatic limit, and then put the operating valve handle in the "stop" position.
2. Stop lifting halfway
If you want to stop the lifting car not moving during lifting, you can step down the clutch pedal, or move the control valve handle to the "middle stop" position, the car will stop.
3. Drop the cargo car and start driving.
(1) When the cargo car has been lifted, the engine is still running, the retractor is engaged, the transmission is hung in low speed forward gear, the control valve handle is in the "middle stop" position, the clutch pedal is pressed down, the warping switch and neutral switch are reset, and then the control valve handle is moved to the "down" position, the cargo car can land. If the control valve handle is moved to the "middle stop" position during the landing, the cargo car can stop motionless during the landing. When the cargo car falls into place, move the control valve handle back to the "middle stop" position, lift the clutch pedal, the car can start driving.
(2) When the engine is not running and the air pressure is about 0.8Mpa, put the control valve handle in the "down" position, and the cargo car can also be lowered. Move the control valve handle to the "middle stop" position, and the cargo car will stop. Before starting the engine, please confirm that the control valve handle is in the "middle stop" position, the stilt switch is in the lower lifting position, and the neutral switch is in the vertical position, then you can step down the clutch pedal to implement the starting running operation.
Three, what should be paid attention to in the operation of self-dumping semi-trailer
1. The self-dumping semi-trailer should keep the jacking hydraulic system intact, work smoothly, operate flexibly, and there should be no stuck phenomenon.
2, loading and unloading should follow the command, do not load and unload materials outside the designated place, strictly prohibit people in the car.
3. When working with digging and loading machinery, the handbrake should be tightened after the dump truck is in place. When the bucket must cross the cab, no one should stay in the cab.
4. When loading, the driver should remind us not to load off-track. When the material is loaded off-track, we should slow down during driving to prevent tipping over.
5. Before unloading, pay attention to the fact that there should be no wires, obstacles and people around the car above the car. When unloading, the car must be stopped steadily.
6. When the car rises to the top, the engine speed should be reduced to prevent vibration of the car. It is forbidden to drive while unloading.
7. When unloading to the foundation pothole, an appropriate safety distance should be maintained with the pit side to prevent the collapse of the pit leading to rollover.
8, shall not be discharged on the uneven, soft, inclined ground, in case of rollover.
9. After unloading, the car should be slightly removed from the unloading position, so that the car can be reset in time and lock the tipping lever before driving away. It is forbidden to lift the semi-trailer.
10. When there is clay attached to the carriage, it should be removed in time to prevent tipping over when it is thick and lifted. It is forbidden to shake the surplus material with a sudden brake.
11. When the carriage needs to be lifted for maintenance, cleaning and lubrication, the supporting wood should be used to hold the carriage, and hydraulic locking is prohibited.
12. In non-jacking operation, the jacking lever should be put in a neutral position, and the fixing pin must be pulled out before jacking.
