There are many reasons for the accident. For example, the damage to pin shaft parts in the top of a wrecker is one of the factors.
Although the wrecking part of the top part of the wrecker is not conspicuous on the “big thingâ€, it is a common and important part that mainly plays the role of connecting and bearing. Such as the boom spindle, support arm shaft, a variety of cylinder pin, fork shaft and so on. In the design of such parts, we choose the size and material of the shaft reasonably according to the force condition of the pin, adopt appropriate parts processing and heat treatment process, so as to satisfy the performance parameters such as precision, strength and hardness of the pin shaft parts, and also consider Pin shafts are fixed and lubricated to facilitate normal inspection, maintenance, and repair of pin shaft parts. However, in spite of this, when the user uses a wrecker, sometimes there are some damages such as bending deformation or even fracture of the pin parts. In the maintenance, there are often cases where the pin is rusted and jammed. This is in addition to the quality of parts design and production. In addition to the cause of the problem, it is also related to the user's overloaded use and improper daily inspection and maintenance. Therefore, when using a wrecker, the operator must use and maintain it in accordance with the technical parameters and operating procedures provided by the manufacturer to avoid damage to the wrecker. And security incidents.
Wreckers commonly used tools fork. When we insert the fork shaft into the seat cover to lift the fore axle or the front leaf spring, under different working conditions, the fork shaft is not subject to the same bending stress, and the severe overload and speeding are used. The fork shaft bending deformation and breakage are likely to occur, resulting in safety accidents.
In addition, when using the fork operation, some users randomly work or use the raised fork to do the work, in fact, this is very unsafe, because under the same working conditions, the fork is subjected to higher bending stress than the fork. To be large, and the bending stress changes greatly, if the strength of the fork shaft is not increased, the fork shaft can be easily deformed and fractured. Three years ago, on an expressway in an area of ​​China's coastal area, an 8-ton wrecker truck was lifting a heavily overloaded truck and it suddenly broke. The arm of the car fell down and lost control. One end hit the wall of the tunnel. Fortunately, the vehicle was driving in the tunnel at the time and did not result in a more serious accident. Otherwise, the consequences would be disastrous.
Furthermore, regular inspection, maintenance and maintenance of wreckers are also important. In the work of wreckers, the pin parts in the top load are generally under heavy load. Although the movement speed is low, some pin shafts are also prone to wear. In particular, relatively rotating shafts are more likely to be damaged, so regular inspections are required. The grease is added to prevent the wear of the parts due to dry friction and to increase the fitting clearance between the parts and to prematurely damage the metal structural parts, thereby increasing the maintenance cost and affecting the normal service life of the wrecker.
In addition, various pin shafts of wreckers have different fixed connection methods, some of which are fastened with bolts, and some are positioned with retaining rings. Because of stress and wear of pin shafts, loosening of fastening bolts may occur. , Fracture, positioning ring falling, etc., resulting in the loss of the entire pin, so the user must check the various pins before using the wrecker, especially difficult to observe the cylinder pin should pay more attention, In order to find and solve problems in a timely manner to avoid damage to the vehicle and trigger a major safety incident.
A screw, an oversight can lead to a disaster! Therefore, we must firmly establish a concept based on prevention, develop good habits for the maintenance and repair of wrecker vehicles, and constantly raise awareness of safety precautions.
Wheel wrecker pins may cause problems
In China, the development speed of wreckers has been rapid in recent years, and its market holdings have also increased. While the level of design and manufacturing of wrecker manufacturers is increasing, China has gradually formed a pattern of road clearance by professional companies. The level of proficiency and specialization in the use of wreckers is increasing. The failure rate of the car and the damage to components and safety accidents that occur when using the wrecker are getting less and less. However, we must also clearly see that, due to the damage of wreckers during the wrecker operations, it is impossible to work and even secondary accidents occur.
