What to do when the truck hits a long downhill Don’t hit the brakes too often

What is the worst conditions of older drivers driving trucks? Long downslope is definitely one of them. Because the long downhill condition is often a high incidence of truck accidents, in order to control the speed, the time and frequency of using the brakes will increase, which also leads to a series of fatal problems, so what problems should be paid attention to in the continuous long slope? How to ensure driving safety?

 regularly checks the vehicle periodically before going downhill

Vehicle running for a long time, there is inevitable “bad condition”, so in daily operation need to regularly check the vehicle regularly, especially the safety configuration, such as the brake clearance is normal, the brake pads excessive wear; air leakage; brake drum cracks; brake back spring normal normally;drying chamberWhether normal and other problems, once there are problems, timely repair or replacement.

In the current transportation market, running to the southern mountain area will require additional water shower device, although suspected of illegal modification, but considering the transportation safety, many long downhill sections will be reminded to fill the water tank, check the water shower equipment, to avoid high temperature brake failure and other situations.

As the saying goes, be careful to sail the ship, when driving a long downhill section, do not take it lightly, even if you are very familiar with the road, but also to do a good job of inspection before driving, to ensure that the parts are in normal work.

 downhill deceleration in advance do not slide in neutral

Learn to defensive driving is a necessary lesson for driving, in the face of long downhill section, no matter whether there is auxiliary braking equipment, should be prepared in advance, keep careful, and pay attention to the side of the road warning signs and safety lane location, etc., including the roadside warning signs may explain the road conditions ahead, such as “xx km ahead long downhill”, etc.

It should be slowed down in advance before the lower long slope, because it can be used in low gearengineThe traction resistance forms a certain reverse pressure on the speed, and low speed driving can reduce the frequency of using the brake, reduce the risk of brake thermal attenuation, advance downshift can also avoid sudden problems, the speed is too fast and can not successfully “block”, resulting in accidents.

At the same time, do not neutral slide, many card friends think “neutral slide will be more fuel efficient”, in fact, this is a mistake, neutral taxi will not be fuel efficient, on the contrary will bring more safety risks, because idle pump gas is small, and long downhill need frequent braking, will use more gas, long distance neutral slide will cause insufficient air in the storage tank, there will be the risk of brake failure.

add auxiliary brake to buy a car optional fluid slow

With the development of commercial vehicle technology, manyheavy truckAvailablehydraulic retarderEngine braking, scheduling brake and other auxiliary braking functions, engine brake is mainly suitable for low speed driving, but need to prohibit driving on slippery roads; and the hydraulic retarder will be more effective at high speed.

If you often run on mountain roads, it is recommended to install the engine braking + pressure retarder, so that you can take into account the braking safety needs of high speed and low speed driving. If the vehicle is equipped with a hydraulic retarder, it can also be used to slow down in daily driving, which can also reduce the frequency of braking and improve the service life of the brake pads.

When the brake also want to have skills, can’t always step on the brake, need according to the speed change on the brake, if faster, can through the engine gear, auxiliary brake deceleration, and then a foot on the brake to slow to release, intermittent brake, try to reduce the frequency of the brake, don’t continuously on, in order to avoid the brake drum temperature is too high.

postscript
Freight industry is a high-risk industry, in the daily operation must pay more attention to safety, summed up is to do a good job before the downhill inspection, downhill when the correct operation, once there is an accident, but also to calm treatment, to minimize the loss, I hope everyone can be safe
