Don't start too hard, pay attention to the dead angle when driving, pay attention to the coordination of gear shifting (speed and speed combination), don't hang up, pay attention to stand firm when unloading, check and replace all kinds of oil frequently, and check the screws in important parts frequently.
Don't step on the accelerator when lifting the car, lift it at idle speed when approaching the limit, and don't forget to turn off the power take-off switch after putting down the car.
1. Before unloading, make sure that there are no people on both sides and the rear of the vehicle, and always check whether the lifting limit device is in good condition (if it is damaged, please stop lifting and contact the after-sales modification factory).
2. Before starting the car after the lifting operation is completed, be sure to turn off the power take-off switch to separate the power take-off from the gearbox and stop the oil pump; Then put the manual valve in the middle stop position to avoid the danger of automatic lifting during driving.
3. The vehicle can only run after the car is reset to be completely attached to the wing surface of the subframe, because the car is likely to have faults and accidents when moving in the lifting state.
4. Generally, modified cars are equipped with lift alarms, and drivers need to check and maintain them every day. If the alarm is abnormal during driving, they should stop and check immediately.
5. In order to prolong the service life of the vehicle when it is stopped, it is suggested that the owner should carry out comprehensive and regular maintenance of the vehicle.
6. Always check whether the lifting and limiting devices are in good condition. If there is any damage, please stop lifting and contact the after-sales modification factory.
7. The goods in the car should be evenly distributed, so don't exercise or dump them seriously unbalanced.
8, to make the gear pump work, should first step on the clutch pedal, and then turn on the power take-off switch, so as to avoid the power take-off gear meshing collision.
9. When the car is lifted, the engine speed should be controlled within 2000 rpm, especially after the car is lifted to 40 rpm, do not increase the throttle to avoid damaging the limit valve and other parts.
10. Before exercise, check that the "power take-off switch and manually operated valve" should be in the separated and lowered state to prevent accidents.
1 1. When the car is lifted, there shall be no facilities or personnel within 5 meters, and the operator shall not leave the cab.
12. When the vehicle is running, the chassis power take-off must stop and the manual valve must be in the middle stop position. It is forbidden to operate the manually operated valve to the lifting and lowering positions.
13. When repairing the vehicle, the whole bracket must be erected. Maintenance personnel are strictly prohibited from entering the bottom of the box to work without a complete support.
Extended data:
1. A dump truck refers to a vehicle that unloads goods by hydraulic or mechanical lifting. Also known as dump trucks. It consists of automobile chassis, hydraulic lifting mechanism, cargo hold and power take-off.
There are two kinds of dump truck compartments: backward tilting and tilting. The movement of the piston rod is controlled by the control system. Backward tilt is common, pushing the piston rod makes the car tilt, and a few tilt in two directions.
2. Working principle:
The structure of the engine, chassis and cab of a dump truck is the same as that of a general truck.
High-pressure oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, and there is a cab safety protection plate at the front end of the carriage.
The engine drives the hydraulic pump through the transmission and power take-off, and the hydraulic tilting mechanism of the carriage consists of an oil tank, a hydraulic pump, a distribution valve, a lifting hydraulic cylinder, a control valve and an oil pipe.
The engine drives the hydraulic pump through the transmission and the power take-off, and the high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and the oil pipe, pushing the piston rod to tip the carriage. Backward tilting is common. By controlling the movement of the piston rod through the control system, the car can be stopped at any required tilting position. The bracket is reset by its own gravity and hydraulic control.
