- Sudden engagement of the clutch while the engine is running: When the engine is running, with the power take-off (PTO) in the “on” position and the lift lever in the “lift” position, suddenly releasing the clutch can cause a significant impact load on the PTO, oil pump, and drive shaft. This sudden engagement can lead to premature damage to these components.
- Abrupt lowering of the fully loaded cargo box: When the lift lever is suddenly pushed to the “lower” position while the truck is fully loaded, the cargo box might drop rapidly instead of descending gradually. This rapid descent can put a huge impact force on the truck’s frame, potentially leading to accidents. Although hydraulic cylinders have throttle devices designed to slow down the descent towards the end of the cycle, this effect is less noticeable when the truck is fully loaded. To avoid this, operators should lower the cargo box slowly and avoid sudden movements.
- Driving without disengaging the power take-off (PTO): After unloading the cargo, if the PTO is not disengaged before driving, the lift pump will continue to operate without a load, causing the hydraulic oil temperature to rise quickly. This can damage the oil pump seals and, in extreme cases, seize the pump. Therefore, after unloading, always ensure that the PTO is disengaged before driving the vehicle.
- Additionally, the selection of the dump truck’s cargo box design should depend on the type of material being transported and the road conditions. This choice significantly impacts the truck’s reliability, safety, lifespan, and overall economic efficiency.
- By avoiding these common mistakes, you can extend the life of the dump truck and improve its safety and performance.
