The Correct Use of Engineering Machinery Tyre Eight Points

1. The smooth start and stop

 

Machinery is in starting, tires from the static state suddenly turn, if started speed of conduct pipe, tires and road surface friction violently, can accelerate the tread wear. Therefore, engineering machinery start don't conduct pipe, the pine clutch and accelerate should cooperate proper, the mechanical slowly started, steady and not shiver, avoid the tires and the ground and accelerate the womb drag abrasion.

 

When the machinery in the emergency brake, tires and the road will appear smooth drag phenomenon, lead to tire and road surface friction violent, produce high fever. So, not only will accelerate tire crown of local abrasion, and is caused extremely easily tread, tire body or tire body types, up from between layers of damage, etc. In the drive, the pilot should be based on the road condition, apply more air brake, the less the brake, try to avoid the emergency brake 

 

2. Moderate speed 

 

Mechanical if speed too fast, tire in pavement will produce slip, cause the wear is intensified. At the same time, high speed road tires deformation number increase, tire temperature rise sharply, tire body sex increases, tires and the road contact area is reduced, in a slightly rough place wheel will be hung up, the frequent travel are jumping, make tires and the road of the probability of wear Wei drag increases, increase the tread wear. Therefore, the driver should according to different conditions control the speed of the car.

 

The soldiers in the downhill driving, should according to the size of the slope, length and road surface, control the appropriate speed. At the same time to pay attention to and traffic moving ahead toward keep 50 ~ 100 m above the safety distance, and driving on the right. In a short zone beyond, we should pay attention to the other side of the brake situation, at any time for speaker. Long and steep slope, the next road is narrow the risk of location, should always be parking, for the car of preparation, take minor brake or exhaust braking to control the speed of the car.

 

In the uphill road, should try to use inertial road. Appropriate variable speed, timely shift, don't wait for mechanical stop again after the start, in order to avoid driving wheel rolling loss, accelerate the abrasion of tyres.

 

Machinery is in turn road, the driver should according to bend turning radius, driving conditions, density and speed speed operation. General appropriate to slow down, don't corner at speed, lest because of the inertial force and centrifugal force function to cause unilateral tire overload drag, accelerate the wear of tire, or even turn up landing accidents.

 

3. Choose appropriate way

 

In the absence of mechanical FenDaoXian road, ensure the safety in the premise of the road should as far as possible in the central road, in order to prevent the tire partial grinding and avoid individual tires for load on and blowout 

 

In the road maintenance machinery construction area road, such as for overhaul road or for rock blasting road surface was covered with sharp stones, application of bio-fuels at low speed, select pavement way to get through, avoid tire for excessive touch attack was serious stabbing or scratch.

 

In through the muddy the pavement, snow area frozen, carries on the observation in advance, the choice is solid, gliding through the small amount of place. Meet the wheels skid, should stop immediately, try out backwards, an alternate route forward. When the same as backward wheels skid, it should be tyre sliding in and out of the mud before and after both sides, or tried to in the wheels on the shop around under and stone, sand or grass. Do not use fierce boom throttle the way through rigid, lest the deeper into the tyres, for in-situ idling and sharp fever, caused by the side of the tire tread and serious scratch 

 

4. The reasonable collocation 

 

Before and after the soldiers, so the tires must be reasonable collocation. The same mechanical assembly tires shall ensure that brand, specifications, structure, decorative pattern, load the same. Radial tire and bias tyre, can't mixed; Rim diameter, width different tyres or section width different tyres shall not mixed packing. Otherwise, will make individual tire wear is intensified, cause early damage or a blowout. For a new tyres, with winter or spring advisable, must according to the provisions of the installation direction of rotation, best will also change all the tyres. If that really need to be old and new round of good will and replace all the tyres. If that really need to be new and old tires collocation is used, its wear degree differ can not more than 5 mm, and should be replaced before the front tires. At the same time, should combine maintenance cycle their tires.

 

5. Normal pressure

 

The tire pressure must be kept in normal. The normal atmospheric pressure, tire crown and road surface contact area is larger, uniform loads, wear normal, if air pressure over the bottom, the stiffness of the tires are down, carrying deformation serious, for child shoulder so that the wear on local intensifies, deformation serious when still can cause tire body heat, causing the cord fatigue, tire body such as layered early loss; If the pressure is too high, tire stiff, elasticity decreased, cord by excessive stretching and break, at the same time as grounding area is smaller, accelerate the tire crown local wear and increased unit area of load, cause early damage or flat tire, this phenomenon is particularly severe in summer. Therefore, the driver before work to check tyre pressure, low in the air.

 

6. Maintenance in time

 

Machinery in motion, if appear weak, difficult operation, body tilt, different sound, and the wobble or burning smell when, should stop immediately check tyre situation. The way when resting, should check tyre pressure and temperature is normal, tire nut is loose, tires are scratching, etc., and examine whether the tread sundry embedded, once found a clear in time.

 

Machinery in the road, tires for constantly bending deformation and fever, lead to tire temperature (with the feel too hot to touch), the tyre pressure also increase, in hot season road, tire pressure rising phenomenon of fever and more outstanding. In that case, must not it with gas or water of the methods to reduce pour cold water on the tyre pressure and temperature, had better stop in shady and cool place again after cooling driving; If need to wade through the way, should first stop to rest, stay cool rear tire can go; After driving maintenance, should also be tyre temperature drop, the car wash with water, or you will make tyre cold snap and happen deformation cracks, early damage caused.

 

In the winter cold conditions long time place wild, should be in the tire cushions, branches, such as wood sand, ban on the use of asphalt and gasoline mixed material daub is on the tyres.

 

7. Choose good stop location

 

Machinery in driving down and arrive station when stop after, and to choose to level off, clean, no pollution of the ground parking, avoid stone against the tires and tire contact grease, avoid to be in on the ramp down, summer should be parked in shady and cool place, avoid tire in the hot sun exposure to the sun; The cold season should be parked at the XiangYangChu shelter, avoid tire and ground freezing. They offend in engineering machinery for a long time, should be a up frame, solution for all tires load, according to the stipulation to the tyre to the standard in the pressure of the 90%, and in the surface layer with a lime stone, also will tire clean, air, painted with IXF rubber prevent ageing coating, in order to avoid sun exposure and reduce the contact with air.

 

8. In store

 

The tire store conditions on the tyres or influence. If in good conditions keep tires, a new tire can maintain 5 years not spoiled or only slight deterioration, if preservation conditions is not good, a new tire may scrap in a year. In a dry, airtight, dark and room temperature in 4 ~ l6 ℃ conditions keep most appropriate. Should not be in the hot room or near the radiator, stove, preservation, and should not be in damp, air circulation big room to keep tires. At the same time, the tyres should press upright or level of pile up place way.
