Why does the truck crane run too far?

With the car crane suddenly running off, some drivers may feel that they need to do the next four-wheel alignment. This kind of thinking is also inevitable. However, there are many reasons for the bias of the car , and the tire pressure is not enough. Adequate will also cause the sloping car, each tread wear patterns uneven degree will also cause the situation of deviation. It is as if this person started to bother with headaches. Therefore, the situation of running out of course cannot solve the problem simply by doing four-wheel alignment.  

When there is a partial deviation in the truck crane, first of all, it can be compared with the rated tire pressure given by the manufacturer. If the tire pressure does not meet the standard, then it will cause a deviation. A pair of front and rear wheels can be reversed, but it is not possible to use a cross-line front-to-back approach. If it is necessary to change the new tires, it is necessary to replace the same brand, and the same pattern of wheels, it is best to replace the four tires together. In addition, another reason may be that it is not very accurate when doing four-wheel alignment. The main pin angle, the front wheel camber angle is not correct, and the front toe angle is too large or too small is the cause of the deviation.  

Under normal circumstances, if there is a failure in the suspension system of the truck-mounted crane , the probability of deviation is very low. Before the vehicle leaves the factory, it has been carefully adjusted and tested by the manufacturer carefully. Some car age crane trucks have caused the cause of deviation that can be more. In addition to the reasons we mentioned above, some reasons such as the front axle shifting, frame deformation, two front leaf spring shrapnel, straight tie rods, and tie rod ball studs appear on the truck crane. It will lead to the sloping car. If the situation of deviation is more serious when braking, then it is necessary to check the braking system properly, because the braking force of the left and right wheels will also lead to deviation. The first step is to first visually check whether there is any hardened, oily, or wet condition on the front wheel's brake disc. If the brake pads and brake discs are normal conditions, check each brake cylinder. , to see if there is a caliper fixed cardboard loose, oil spills, as well as the friction plate back into place and so on.  

The good and bad steering brakes also have a direct impact on the straight driving of the crane. If the connectors are loose due to friction, write-off, bearing, and bushing wear due to friction, it will also cause the crane to swing in the course of driving and it will not be able to move in a straight line. When the vehicle is lifted, the tyres will be scrapped and aborted under mild conditions. In severe cases, tyre explosions will occur. Even the danger of losing control of the vehicle, etc. may arise.
