Tipper Truck Winter Maintenance Guide

date:2026-01-07

As the temperature gradually decreases, the low-temperature environment in winter places higher requirements on the performance and reliability of dump trucks. In order to ensure the safe operation of HOWO dump trucks, SHACMAN dump trucks and other models in cold climates, extend their service life and reduce failure rates, this "Winter Maintenance Guide for Dump Trucks" is specially formulated. Personnel in relevant positions are requested to strictly implement the following maintenance measures to jointly ensure the winter attendance rate and operational safety of dump trucks.

1. Engine system maintenance

- Replace engine oil in winter: Use engine oil with low viscosity and suitable for low-temperature environments (such as 5W-30 or 0W-40) to ensure smooth cold start of the dump truck.

- Check the antifreeze: Make sure the freezing point of the antifreeze is more than 10°C lower than the local minimum temperature to prevent the cooling system of the HOWO dump truck or SHACMAN dump truck from freezing. It is recommended to replace it every two years.

- Preheat the engine: Preheat for 3 to 5 minutes before starting to prevent the dump truck from running at high speed when the cold engine is cold and reduce wear.

2. Fuel system maintenance

- Use winter diesel: Dump trucks in northern areas should use No. 10 or No. 20 diesel to prevent fuel from solidifying and causing blockage.

- Add anticoagulant: Diesel anticoagulant can be added to the dump truck fuel tank to prevent waxing.

- Keep the fuel tank full: Reduce air humidity entering the dump truck fuel tank to prevent condensation from freezing.

3. Tires, brakes, and hydraulic systems

- Check the tire pressure and wear: the tire pressure of the dump truck is easy to decrease at low temperatures and needs to be replenished in time.

- Check whether the brake pads and brake pipes are leaking or aging to ensure that the dump truck braking system is sensitive and reliable.

- Special attention should be paid to the lifting cylinder and hydraulic oil of the dump truck:

- Use hydraulic oil with good low-temperature fluidity (such as L-HV46 anti-wear hydraulic oil).

- After starting, perform several no-load test lifts to allow the hydraulic oil of the HOWO dump truck or SHACMAN dump truck to fully circulate and heat up before starting the operation.

Winter is a period when special vehicles such as dump trucks are prone to breakdowns. Scientific maintenance can not only improve vehicle reliability, but also effectively prevent safety accidents. All teams are requested to strictly implement the requirements in this maintenance guide for HOWO dump trucks, SHACMAN dump trucks and other models, and flexibly adjust the maintenance cycle based on actual working conditions to ensure that each dump truck survives the winter safely and efficiently.
