Sanitation trucks are an indispensable tool in modern urban cleaning projects, serving as a reliable assistant for city cleaners. Vehicle maintenance is a long-term commitment, and during winter, with the low temperatures and dry conditions, many car parts become more fragile. Without proper care, this can affect the overall operational efficiency and safety of the vehicle. Therefore, winter vehicle maintenance is particularly important. So, what kind of maintenance should be done for sanitation trucks in winter? Next, the editor from the sanitation truck manufacturer will guide drivers through some winter maintenance tips for sanitation vehicles.

Regular inspections of the three electrical systems

Firstly, we should enhance the maintenance efforts for sanitation vehicles to reduce various issues with components due to special environmental conditions. We need to prioritize the inspection and maintenance of the battery, motor, and controller. Drivers should check the wiring harness and connector installations of the three electrical systems before departure and after returning. They should also pay close attention to the vehicle's dashboard for any fault indicators. If a fault occurs, drivers should immediately stop the vehicle, contact the after-sales team for resolution, and then continue use.

Ensure that vehicles are charged at least once a month if they are parked for extended periods to prevent battery drainage.

Battery capacity tends to decrease and automatic discharge is more common during the cooler autumn and winter months. Therefore, it is recommended to increase the frequency of charging to prevent the battery from becoming depleted.

Electric sanitation vehicles should be parked in indoor locations with relatively moderate temperatures, as parking them in environments with lower temperatures not only damages their batteries but also causes corrosion to their body appearance.

Item 2: Inspect undercarriage and upper assembly antifreeze

As winter approaches, inspect the undercarriage and overhead cooling system antifreeze for any shortages or degradation. Select the appropriate antifreeze based on the temperature environment, and promptly replenish or replace it if necessary.

III. Timely Replacement of Hydraulic Oil

Due to the significant drop in temperatures during the fall and winter seasons, the hydraulic oil within the hydraulic system piping of waste collection vehicles becomes very thick. Inefficient oil flow during operation can lead to abnormal wear and irregular movement of the vehicle's functions. Therefore, it is necessary to change to appropriate gear oil and hydraulic oil based on the local winter climate temperatures. In the hydraulic system of waste collection vehicles, H-46 anti-wear hydraulic oil is generally used during summer, while a thinner anti-wear hydraulic oil, H-32, should be chosen for winter. When changing the hydraulic oil, it is essential to first clean the hydraulic oil tank and replace the hydraulic oil filter element.

Four: Timely Replacement of Hydraulic Oil

It's well-known that water freezes when the temperature drops below zero. Once frozen, it expands, which can cause破裂 in the water pumps and ball valves of洒水车 if not properly drained in cold conditions. Therefore, for洒水类环卫车 operating in temperatures below 0℃ or during winter, it's essential to open all manual ball valves immediately after each day's operation to fully drain the accumulated water from all pumps, water tanks, and the water system.
