Can the tires touch the ground when the pump truck is under construction?

  When the pump truck is under construction, can the tire touch the ground? It's always been a matter of debate whether or not you can touch the ground. Among the pump truck operators is an ongoing controversy. In addition to adapting to local conditions, some people believe that a tire touching the ground will make the vehicle more stable, while others believe that it is better to take the tire off the ground.

  Two completely different statements, which group of people is right? In fact, here said the tire suspension is not, that is, a car when the whole body off the ground.

  Tire to ground, damage connection mechanism

  Regardless of the force released by the outrigger, the force passed on to the tire and the joint mechanism is also very large. Because the tire can not discharge force near the ground, they only need to use the clearance and deformation of various connecting mechanisms to resolve, and as time passes under the impact, it will cause irreversible damage to the rear axle, steel plate suspension, pull rod and other parts of the vehicle.

  In addition, under the constant impact, the friction between the tire and the ground will also cause abnormal wear of the tire.

  Body suspension, ease the impact of pumping

  After the body suspension, only need to use the leg of the torsion to resolve the impact of pumping, will not damage other institutions. Some friends may say that the leg will be injured, please rest assured. Pump car in the design, the various components to bear the strength of the magnitude of the need to go through repeated calculations and experiments, generally will not occur in this case.

  The suspension component changes into a damper to reduce the impact force

  In addition, after the tire suspension, this part of the body can also be used as a block of dampers, when the impact generated, passive to produce a reverse force to offset the impact, the impact generated by the smaller pump. Although it may cause some damage to these structures, it is negligible compared to the tire on the ground.

  Dampers -- stop the building from shaking

  If the pump truck operation scenario as a high-rise building, the impact of the pump truck work is a series of earthquakes and typhoons. The suspended components, such as tires, can be seen as dampers of the building. Of course, they are simple dampers. That is, when a pump truck, no matter what impact force it produces, the tire assembly will produce a reverse force to relieve.
