If a high-altitude vehicle is not fully maintained at ordinary times or when normal operations are not used to perform operations, the time limit for use of the leaf spring of the vehicle will be shortened, and damage and the like will occur. This abnormal situation is also known as early damage. Early use of the steel plate to damage the more common use cases is in those mountainous regions where the road conditions are relatively poor. What are the main reasons for the early damage to the steel plate?
1. Loosening of center bolts or riding bolts of aerial vehicles may also increase the load on the main piece of the leaf spring, which is also one of the reasons leading to early damage. When the vehicle is being maintained, it is still necessary to check the tightness of the center bolt and the saddle bolt. When there is damage, it needs to be replaced in time.
2. During the normal driving of the aerial working platform, if an emergency brake is used, the leaf spring will be caused due to inertia, especially the front leaf spring will bear excessive tensile stress and bending. The stress, when it completely exceeds the allowable stress, is likely to cause the leaf spring to break. Therefore, when the aerial vehicle is driving, it is still driven at economical speed and medium speed, and the exhaust brake of the engine is often used, and the emergency brake is used less frequently.
3. The long-term operation of aerial vehicles under very harsh road conditions, or driving at too high a speed, will increase the frequency of leaf springs, increase the degree of deformation, and cause damage to leaf springs due to accelerated fatigue. Happening. If you want to better increase the lifespan of the leaf spring, the vehicle must still use the economical speed to drive, and encounter those very poor road conditions also need to reduce the speed of travel.
4. When high-altitude vehicles need to make a turn, if a high-speed emergency turns, a large centrifugal force will be generated. At the same time, the load force of the outer leaf spring will be greatly increased, and the leaf spring of the aerial work truck will be accelerated. damage. In order to better protect your vehicle's leaf springs, it is necessary to slow down when turning.
5. The lubricated effect of the leaf springs of the aerial vehicles is not good, and the shock absorbers also malfunction and fail, which are also factors of early damage. Usually also need to pay more attention to this aspect of maintenance.
