Rear tipping semi-trailers are a common means of transportation, widely used in the transportation and loading and unloading of various goods. The following problems may occur during use:
Difficulty in lifting the car body: The reasons may include insufficient oil in the tank, blocked oil tank filter or pipeline, oil pump failure, stuck lifting switch or distribution valve, serious imbalance of overflow valve, and stuck lifting cylinder and limit valve. Solutions include checking the oil level in the tank, cleaning the filter or pipeline, replacing the oil pump, repairing or replacing switches and valves, adjusting the overflow valve, cleaning the lifting cylinder and limit valve, etc. The car body is lifted slowly and weakly: The reasons include air entering the hydraulic system, the lifting cylinder limit valve is not tight or imbalanced, the sealing ring is not tight or worn, and the oil level in the tank is insufficient. Solutions include exhausting, replacing or adjusting the limit valve, replacing the sealing ring, and replenishing the oil, etc. The car body falls down automatically after being lifted: The reasons include one-way valve stuck, poor sealing of lifting cylinder seal ring, pipeline leakage, etc. The solutions include cleaning or replacing one-way valve, replacing seal ring, checking and repairing pipeline leakage, etc.
Gas self-locking: The reasons include main vehicle without air supply to semi-trailer, main vehicle two gas lines supplying air at the same time, main vehicle two gas supply lines reversed, double exhaust chamber core ventilation, etc. The solutions include checking the main vehicle gas supply, adjusting the gas line connection sequence, replacing damaged gas chamber core, etc.
Poor braking performance: The reasons include insufficient main vehicle gas volume, brake pipe leakage, double exhaust chamber gas core leakage, hand brake seal leakage, etc. The solutions include checking and replenishing the main vehicle gas volume, repairing or replacing leaking parts, adjusting the hand brake seal, etc.
The car body cannot be lifted when overloaded: Reasons include serious overloading, the vehicle is parked on an inclined ramp, and leakage of pipes and valves. Solutions include avoiding overloading, ensuring that the vehicle is parked on a flat surface, and checking and repairing leaking parts. Air leakage during braking: Reasons include perforation of the brake cup of the master cylinder and leakage of the brake air pipe. Solutions include replacing damaged brake cups, repairing or replacing leaking air pipes, etc.
Circuit failure: Reasons include damaged bulbs, missing ground wires, and poor connection of power connectors. Solutions include replacing damaged bulbs, checking and connecting ground wires, and repairing or replacing power connectors, etc. 5. Vehicle body structure problems:
Vehicle body deformation or damage: Reasons include long-term heavy loads, accident collisions, etc. Solutions include repairing the vehicle body or replacing damaged parts to ensure the integrity of the vehicle structure.
