INTRODUCTION:

Heping Road and bridge inspection car rental bridge inspection professional provides bridge maintenance car rental service If the battery is directly charged, its service life will be shortened. Generally, the initial charging of the battery is about 1 hour after filling the electrolyte with a small current. If the bolt is too tight - permanent deformation, there are many fasteners connected with bolts and nuts on the automobile. It should be ensured that they have sufficient pre tightening force, but they can not be tightened too tightly. If the battery is tightened too tightly, on the one hand, the connecting parts will be in the On the other hand, permanent deformation will occur under the action of external force; on the other hand, permanent tensile deformation will occur on the bolt, and the pre tightening force will decrease, and even cause sliding buckle or fracture. The effect of waxing in circle is poor. Many people wax the car body in a circle. Without balance weight, only the upper part of the structure is rotated, and the back cable is used to balance. At the same time, it is still weak, and more and more new materials, new technologies and new structural forms are used. In order to accumulate engineering experience in this field, it is necessary to do some inspection work,
