What Precautions Should be Taken When Using A Dump Truck Daily?

Driving and Operation

Starting: Warm up the engine first. Once the coolant temperature is reached, confirm the lift switch is in the off (stop) position. Observe the road conditions and start driving only after it is safe.

1. Driving:

Driving in gear is prohibited: The power take-off (PTO) must be in the off position (red light not illuminated) while driving. Driving with it engaged is strictly prohibited to prevent accidental lifting of the truck bed.

Smooth driving: Avoid sudden starts, sudden braking, and forced gear shifts. Select the appropriate gear according to road conditions to avoid overloading.

Beware of blind spots: Dump trucks have blind spots; be especially careful when turning and reversing.

2. Loading:

Control Load: The load should not exceed the rated load capacity. Distribute the cargo evenly to avoid severe uneven loading.

Before Unloading: Check that there are no personnel around and behind the vehicle. Confirm that the ground is level and the vehicle body is stable.

Lifting Operation: Control the engine speed below 2000 rpm. Avoid excessive throttle.

3. After Unloading:

Must be in place: The cargo box and chassis must be fully closed and locked before driving. Otherwise, the vehicle may tip over due to a rear-heavy load.

Disengage PTO: Ensure the PTO is disengaged (switch in the off position).

4. Special Operation:

Avoid Improper Operation: Do not push the handle to the lowering position during lifting, as this will cause a significant impact on the chassis.

Large Materials: When unloading large materials, consider removing the rear cargo box to prevent damage.

Routine Inspection and Maintenance

Before starting: Inspect key components such as brakes, tires, lights, and cargo box latches.

Hydraulic System: Maintain normal hydraulic fluid levels and regularly check for leaks and prevent foreign objects from entering the system.

Chassis: Regularly check for looseness at the connection between the chassis frame and subframe.

New Vehicle: The first service is crucial; check screws, fluids, and the hydraulic system for proper functioning.

Conclusion

As core equipment in engineering transportation, the selection and maintenance of different type dump trucks directly determine the operational efficiency and profitability of a fleet. Whether it's a rigid model for heavy-duty mining or a new energy dump truck for urban infrastructure, only by combining operational requirements, brand service, and cost control can dump trucks maximize their value, solidify the transportation foundation for engineering operations, and help practitioners achieve their operational goals of cost reduction and efficiency improvement.
