In the cold winter, Sany electric mixer truck should keep warm like this

Overnight, winter is a challenge for many construction sites. And as a "Hercules" on the construction site - electricMixer trucks, its performance is directly related to the progress of the project. Today, we will talk about how to properly maintain the electric mixer truck in the low temperature and slippery winter to ensure that it can perform at its best.

Power battery: scientific charging, pay attention to warmth

At present, the power system of pure electric mixer truck is mainly lithium-ion battery, due to its chemical characteristics, the low-temperature performance will be weaker than that at room temperature, which is not suitable for high-current charging and discharging, therefore, low-temperature vehicles will cause some changes:

First of all, the power battery (large battery) discharge capacity is reduced, the vehicle dynamics are weakened, if the vehicle continues to be in a low temperature environment and does not operate, it is recommended to park the vehicle in a thermal insulation environment when not in use, and it is best to put it into storage in time.

2. In a low-temperature environment, high-current charging will cause damage to the power battery (large battery) system and reduce the service life of the power battery. In order to protect the power battery system, in a low temperature environment, the charging power will be automatically adjusted according to the temperature of the power battery, and the charging time will be increased by 0.5-1h.

System components: timely inspection to prolong life

1. When the wiper glass water and antifreeze are driven for 2 years or the mileage reaches 60,000 kilometers, they need to be replaced in time, and the freezing point of the selected antifreeze should generally be more than 10 °C lower than the local temperature.

2. Regularly pull the drain valve of the air storage cylinder, and the chassis air storage tank should be drained in time to avoid cold weather, water droplets enter the braking system and freeze, resulting in ice failure.

3. After each work is completed, the mixing drum must be washed with coarse stones and water, operated according to the discharging method, and the water in the drum should be drained, and the cement residue around the surface and base of the mixing drum should be washed at the same time, and the correct treatment and maintenance can prolong the service life of the mixing drum.

In terms of car use: reasonable control and safe driving

1. In winter, the number of car washes should be appropriately reduced, and the door of the mixer truck should be opened when washing the car, rinsed with warm water, and the water traces should be wiped in time to prevent the residual water in the door from freezing the door.

2. When encountering bridge decks, back-sun areas, and slippery roads with rain and snow, you should drive slowly, step on the accelerator lightly, and lightly step on the brakes to minimize the braking to prevent the vehicle from skidding caused by floating water and thin ice, causing the vehicle to lose control. Keep a sufficient safety distance from the vehicle in front when driving, and do not grab the traffic light to improve driving safety.

3. When driving on icy roads, it can turn on the anti-lock braking and anti-skid rotation control (ABS/ASR) system of the driving wheels. It can effectively prevent the vehicle from skidding the driving wheels during starting and acceleration and improve traction; Prevent the driving wheels of the car from idling on asymmetrical roads or when turning, and keep the driving stability of the car.

Fourth, in terms of climbing, when the wheels are seriously skidding on steep slopes, gravel or slippery roads, the ASR switch can be temporarily turned off, and the inter-axle lock and differential lock can be opened to improve the driving ability of the vehicle and speed up the vehicle to get out of trouble.

Driving an electric mixer truck in winter is not only a test of the driver's skills, but also a challenge to the performance of the vehicle. Only by being well prepared can we ensure that the progress of the project is not affected by the weather, and at the same time ensure the safety of drivers and construction personnel. I hope every driver can keep these maintenance tips in mind, so that the electric mixer truck can also play its best performance in the cold winter!
