Proper daily maintenance of dump trucks is the most effective way to reduce breakdowns and extend vehicle service life, especially for heavy-duty tipper trucks working on mining sites, quarries and earthmoving construction projects in Africa and the Middle East.

Chassis and Suspension Inspection
The chassis and leaf spring suspension bear most of the load for a heavy duty dump truck. You should regularly check fasteners, spring plates and shock absorbers. Loose bolts and cracked leaf springs are common hidden dangers under continuous heavy load. For HOWO 6x4 mining dump trucks used on rough off-road roads, weekly inspection is highly recommended.
-
Hydraulic Tipping System Care
The hydraulic lifting system is the core component of the tipper truck. Check hydraulic oil level and oil quality frequently. Replace contaminated hydraulic oil on schedule, inspect hydraulic pipelines for oil leakage, and protect the tipping cylinder from impact and scratches. Damaged hydraulic parts will cause slow lifting or failure to unload cargo, delaying your mining and construction work.
-
Cargo Box and Body Maintenance
The dump truck cargo box is made of high-strength wear-resistant steel. After transporting rock, ore and muck, clean residual materials inside the tipper body in time to avoid material buildup and corrosion. Check welding seams and wear plates regularly. Repair cracks promptly to prevent cargo box deformation during heavy loading.

Engine and Lubrication Maintenance
For Sinotruk HOWO dump trucks, follow the service cycle to change engine oil, oil filter, fuel filter and air filter. Dust is heavy at construction and quarry sites. A clogged air filter will reduce engine power and increase fuel consumption. Check engine coolant level to avoid overheating during long-hour continuous operation.
-
Tires and Braking System Check
Deep tread heavy-duty tires suffer heavy wear on mine roads. Check tire pressure, tread wear and sidewall damage before every shift. The braking system directly relates to driving safety. Inspect brake pads, brake drums and air pipelines regularly, especially for downhill mining transport.

Pre-operation Daily Checklist
Before starting work, operators should carry out a simple visual inspection: check oil leakage, water leakage, tire condition, lights and warning devices. Timely daily checks can avoid unexpected downtime and costly emergency repairs.
