What are the advantages of the semi-trailer?
The semi-trailer has many advantages. The semi-trailer transports a large amount of cargo, and the vehicle has a high running stability coefficient, which is suitable for long-distance transportation, and the operation of the semi-trailer is relatively easy. The basic principle and common Like the dump truck, you should pay attention to controlling the angle and strength when operating. Semi-trailers are generally suitable for small and medium-sized projects, so relatively speaking, it is less difficult to use and safer.
Because semi-trailers are inclusive, they have unique uses in various fields. I will introduce you to the operation skills of the semi-trailer today. The starting air pressure of the semi-trailer needs to reach 0.81Mpa, and the first step is to use the first gear. When starting, you should first step on the accelerator pedal after the gear is engaged. Do not step on the throttle door. Do not step on the throttle and then stop the gear. Do not step on the brake pedal or Step on the big throttle when you release the hand brake.
When the shifting handle is placed in the driving position, the throttle should be slowly depressed. When the semi-trailer is running, avoid the high slope or low valley exceeding 12°. The temperature during continuous operation should not exceed 120 °C to ensure the lubrication of the transmission is good. If the semi-trailer is equipped with a hydraulic automatic transmission with a downhill brake, it can be driven in the Z position when the slope is 8%-10% under the empty car; when the slope is 8%-10% at full load, the L position is required. Drive, otherwise the semi-trailer automatic transmission oil temperature rises and the performance is degraded. If the semi-trailer needs to use the engine brake or climb the long slope when driving downhill, the transmission may repeatedly upshift downshift between the third gear and the overdrive.
At this point, the overspeed switch should be cut off. After the above condition is removed, the overspeed switch is turned on. When the transmission shifts from the low range to the high range (or from the high range to the low range), the overrun is prohibited, and at this time, the throttle should not be violently added, otherwise the automatic transmission, especially the shift clutch, will be The friction components of the brakes are seriously damaged. When the semi-trailer is going downhill, it is forbidden to change the high and low gear positions; when going uphill, the gears should be downgraded step by step; when going up and down, the transmission should be in the low-range zone, and it is strictly forbidden to grab the gears. Stop and then store the gear.
Do not drag in the neutral condition of the transmission, slide for a long time or step on the clutch to slide. When parking the semi-trailer, the shift lever should be placed in the neutral position of the low-range, and the shift handle is not allowed when the vehicle has not stopped. Switching from forward to reverse is also not allowed to change from reverse to forward, as this will result in damage to the actuator's actuators, primarily the clutch and brake.
Semi-trailer has many advantages. It has a unique shape, complete functions, and strong adaptability. It can adapt to various road conditions and is very convenient to use. If you need a semi-trailer right now, the semi-trailer has good performance characteristics and is easy to operate. However, the pilot master should check whether the accessories of the car are abnormal before using the semi-trailer to ensure the safety of driving.
