Heavy truck to prevent skidding skills are:
1, the use of anti-skid chain to increase friction
We also know the role of the anti-skid chain, the installation of anti-skid chain increases the friction between the tire and the snow and ice pavement, so that the driving is more stable, we should pay attention to the timely removal of the anti-skid chain after spending the snow and ice pavement, otherwise the damage to the tire is great.
2. Don't overdo it
If the tire rotates at high speed, the adhesion between the tire and the ground will be reduced, and it is easy to slip. Truck drivers must remember to slowly lift the clutch, light oil, usually 2 gear start, then can choose 3 gear start, to reduce torque. If the start of skid phenomenon, immediately full throttle, gently adjust the steering wheel, to ensure that the vehicle into the correct driving direction.
3, the use of engine inertia braking
It is necessary to drive slowly in low gear on snow and ice covered roads. It is better to make full use of the "drag" braking of the engine to slow down. It is better to maintain the adhesion between the wheels and the road through the "drag" braking of the engine than using foot braking. If you want to drive at a low speed, consider driving in a lower gear and keeping the engine running at a slightly higher speed. If you gradually lift the throttle, you gain engine braking. Whether or not the truck is equipped with ABS, the brake should be pressed several times before braking, which can remind the car behind to slow down to avoid rear-end collision.
When using engine exhaust braking and other methods, it is necessary to pay more attention when driving in snow days. The exhaust valve brake system, which can be electronically controlled and adjustable type, needs to operate the engine exhaust valve brake system with low power according to the instructions. For the non-electronically controlled adjustable type, especially the case of high speed, it is forbidden to use the engine brake.
Tractor in use, especially need to pay attention to, because the engine brake only has a role in the tractor, the trailer by the influence of the front at a relatively fast speed when it is very easy to fold accident.
4. Matters needing attention on the slope
When going downhill in the snow, it is very dangerous. When going uphill, you must keep double distance with the car in front of you, and strive to complete the climb "at one go". In case the wheels slip because of ice on the ground when climbing a hill, you can put some sand or felt before and after the wheels to increase friction. When necessary, can also be used to make the hard ice on the ground into a cross groove, in order to avoid the wheel skid. When going downhill, you must smoothly change to the first gear, and use the low gear to reduce the speed of the car.
5. Don't change lanes too often
Don't change lanes too often. If you have to overtake another car, you should keep a safe distance from the other car. And when you overtake another car, you should not rush back to the original road. Instead, you should keep enough distance from the car behind you before returning to the original road.
6. Avoid rushing direction
When driving in snow, avoid steering, accelerating or braking sharply, and drive as low as possible. Snow can lead to icy or muddy roads, which can reduce tire grip. If on the road, encounter the vehicle sideslip, immediately release the throttle. Don't slam on the brakes, you'll probably slip sideways. If sideslip has occurred, release the brake immediately to allow the steering wheel to regain control of the car.
Slow steering. When steering, you should first slow down, increase the turning radius appropriately and play the steering wheel slowly. The operation of the steering wheel should be smooth and slow, otherwise sideslip will occur and the rear of the car will be thrown out to the outside.
7. Choose the right tires
You can choose professional snow tires, snow and ice can play a good grip and drainage capacity. If the snow and ice weather on the way, it is impossible to replace the snow wheel in time, you can let some air out of the truck tire, so that the contact surface between the tire and the ground is increased, and the grip of the tire is improved.
