1. Different features

1. Tractor features:

Anti-skid: when driving on wet roads such as snow, the driving wheels are prevented from idling, so that the vehicle can start and accelerate smoothly. Especially on snowy or muddy roads, the traction control system can ensure the smooth acceleration of the vehicle and prevent the vehicle from swaying or rear-end collision due to the slip of the driving wheel.

flexibility: when towing vehicles, the train has better maneuverability and performance.

reliable operation: ensure the reliable, convenient and fast connection of the trailer.

stability: the traction force can be smoothly transmitted to the trailer, which has a certain buffering effect on the impact tilt.

2. characteristics of semi-trailer: compared with "single car", semi-trailer can improve the comprehensive economic benefits of road transportation. The transportation efficiency can be improved by 31-51%, the cost can be reduced by 31-41%, and the fuel consumption can be reduced by 21-31%. More importantly, the use of semi-trailers can also promote the organization of logistics in China.

2. Different uses

1. Use of tractors: It is often used to transport a large number of goods between workshops, such as transportation from automobile manufacturing warehouses to assembly lines and luggage transportation at airports.

2. Use of semi-trailer: Semi-trailer is the main transportation volume, so it is not easy to divide large items, such as excavators, etc. Fencing is more suitable for fresh items, such as vegetables, fruits and so on. Semi-trailer is more suitable for towing bulk goods and moisture-proof goods.

Maintenance of semi-trailer and tractor:

1. Tire inspection

Tire pressure should be checked at room temperature every month. If it is lower than the normal standard, the tire pressure should be replenished in time. The air pressure should not be too high or too low, otherwise it will affect the driving safety. Check tire cracks, and replace them in time if any potential safety hazard is found. When replacing tires, the models should be the same.

2. battery maintenance inspection

check whether the battery is safe and reliable and whether the hydrogen is between the upper limit and the lower limit. When approaching the offline, distilled water or distilled water should be added to the online in time. Keep the positive and negative cables of the battery in good contact and keep the battery clean and dry.

after rewiring for about half a month and starting the engine for about 21 minutes, if the power supply is obviously insufficient, it should be charged in time.

3. Check the fluid level of the clutch master cylinder

It is normal that the clutch gear is between the high position and the low position. If it is lower than the standard line, it may damage the main pump or the auxiliary pump bowl. When the engine is running, it will be difficult or impossible to archive. Please go to the nearest maintenance station for maintenance immediately.
