Open the tarpaulin or box cover of the compartment
Open the rear door locking device
Depress the clutch and wait for 5 seconds when the transmission is in neutral state
Combine the power take-off
Engage the low gear ( 4th gear below)
Put the handle of the air control valve in the up position
Release the clutch and the 3 axle semi end dump trailer for sale starts to lift
You can step on the engine accelerator properly but it must be controlled within 1500 rpm
When the cylinder reaches the maximum stroke or the limit valve works, put the air control valve handle in the stop position.
Depress the clutch and wait for 5 seconds
Disengage the power take-off
Disengage the transmission gear
Release the clutch
Slowly turn the handle of the air control valve from the stop position to the descending position (The pneumatic control valve of the hydraulic lifting system of the rear dump semi-trailer is a proportional control valve, which can control the descending speed of the oil cylinder. The closer the handle is to the descending position, the faster the descending speed of the oil cylinder).
After the cargo box of 3 axle semi end dump trailer for sale is completely lowered, wait 30 seconds and place the handle of the air control valve in the intermediate stop position.
al Specification of 3 Axle Semi End Dump Trailer for Sale
The hydraulic cylinder of the 3 axle semi end dump trailer is a special cylinder for lifting, and it is strictly forbidden to use the cylinder as a stable support for the vehicle;
The time that the cylinder exposed to the air in the lifting state should not exceed 2 hours (30 minutes in the humid air). Otherwise, the cylinder will be oxidized and corroded;
It is strictly forbidden to disassemble and adjust the relief valve on the lift valve. Otherwise, the hydraulic system will lose its safety protection function and cause an accident;
When loading goods, ensure that the vehicle is loaded evenly from front to back and from left to right. If the goods are loaded too far forward, the hydraulic system will be overloaded. If the goods are loaded too far behind, the 3 axle semi end dump trailer for sale will overturn when unloading.
When unloading the vehicle, it must be ensured that the unloading ground where the vehicle is located is firm and flat, the vehicle is kept level, and the main vehicle and the trailer are in a straight line;
During the lifting operation, the operator cannot leave the operating position. It is strictly forbidden for anyone to stand or walk in the working area;
During the lifting operation, the operator must pay attention to the influence of the lateral wind. It’s because the force of the lateral wind acting on the surface of the car body will cause the vehicle to roll over due to the larger dimension of the dump semi-trailer body.
The cargo carried by the 3 axle semi end dump trailer for sale should not be higher than the rear door as much as possible (unless it can be guaranteed that it will not block the rear door) and the rear door locking device must be opened before lifting and unloading. Otherwise, the cargo will be crowded at the rear of the vehicle during unloading and the vehicle will overturn.
When unloading the goods under low temperature condition such as below 0 degrees, be sure to pay attention to whether the goods are frozen. Otherwise, the vehicle will roll over due to the imbalance between the left and right when unloading;
Do not move the vehicle when the carriage is lifted, and do not use sudden braking to unload sticky goods. Otherwise, it will cause the 3 axle semi end dump trailer for sale to roll over or damage the oil cylinder;
If the lift angle of the car body reaches about 25 degrees (the car has been lifted halfway), and the cargo in the car has not been unloaded, be sure to stop the lift and check the cause of sticking;
If you feel that a rollover may occur during lifting, please stop lifting and slowly drop the box。
After waiting for about 30 seconds for the cargo box to lower completely, be sure to put the handle of the air control valve in the middle stop position. Do not start the 3 axle semi end dump trailer for sale in the lowered position in order to avoid all the hydraulic oil in the hydraulic cylinder returning to the hydraulic oil tank, causing the problem of cylinder cavitation and fuel injection in the fuel tank.
When the vehicle needs to be lifted during repair or maintenance, please make sure that the vehicle is safely supported. Working under the unsafely supported vehicle will endanger life.
