What Is Tested Before an Underground Mining Dump Truck Leaves the Factory?

Braking and Power System Checks

The braking and power systems are also important parts of the factory inspection.

The test can verify whether the vehicle starts normally, responds correctly to operator controls, shifts properly, and brakes as expected.

For diesel models, the engine and transmission are checked during basic driving operation. For electric configurations, the inspection can focus on the electric drive system, battery-related components, controls, and vehicle response.

However, factory testing does not reproduce every underground condition. Actual braking requirements can change according to vehicle load, road gradient, surface condition, and haul distance.

This is why customers should provide the mine’s operating conditions before choosing an underground mining dump truck.

Why Factory Testing Matters Before Delivery

Factory testing provides a final functional checkpoint before transportation.

It allows the manufacturer to verify that the major systems work together as a complete vehicle. It also provides an opportunity to correct issues before the truck is shipped overseas, reducing the possibility of discovering basic problems only after arrival.

For buyers, factory testing can help answer practical questions:

• Is the truck ready for delivery?
• Are the major operating systems functioning normally?
• Does the hydraulic dumping system work correctly?
• Does the truck respond properly during driving?
• Has the completed vehicle been checked before shipment?

RUIXIN has also carried out factory inspection and testing for larger mining dump trucks before overseas delivery, including checks of the chassis, hydraulic system, steering, braking, power system, tires, and electrical components.

Factory Testing Is Only One Part of Equipment Selection

A factory test confirms the truck’s basic operating functions, but it does not determine whether a particular model is suitable for every mine.

Before selecting an underground mining dump truck, buyers should provide key project information:

Payload + tunnel dimensions + haul distance + road gradient + loading equipment

These factors affect the suitable truck configuration.

For example, a compact mining dump truck may be more practical for a restricted underground roadway, while a higher-payload truck may be considered when the mine has sufficient roadway width and a higher material transportation requirement.

The truck should also be matched with the loading equipment. If an LHD loader is used for loading, its bucket capacity and loading cycle should be considered together with the dump truck’s payload and cargo box.
