For the repaired portion

Clarify the demolition pits pieces or parts of the quality of the parts for the soft heavy lifting equipment should use reliable auxiliary operations. Reduce labor intensity is also conducive to human , machine safety . Cong on the need to use special removable parts and components , use the specified tools for repairs. Assembly demanding and difficult technical conditions disintegration devices shall be dismantled into a complete unit.
    ( Five ) to determine the cause category
    Big crane wheel failure can be divided into two categories original N , one is mechanical damage , and the other connected to relaxation , the gap increases. For the damage of the former , the latter kind of non -invasive that while " some non- invasive cause of the malfunction is difficult Jin Ming , must be carefully analyzed .
    ( Six ) to determine repair solutions and repair all impurities intrusion, pipe blockage , even traumatic cause of the malfunction is usually easy to check
On wheeled cranes noninvasive hand stacker fault within the shell requires cleaning , lubrication , supplemented, adjusted , tighten the other maintenance that can eliminate the fault . The injury also pick up enterprises to determine fault to determine which parts need to be replaced sail * what needs to be repaired , according to the process and equipment conditions , and to determine the economics of repair parts for repair based on other factors to consider.
    Repair replacement parts ready , in strict accordance with the reverse order of removal recorded on the assembly process or system restore individual parts assembled one by one until the entire installation. Appropriate in the course of maintenance work simultaneously .
    For the repaired portion , functional tests should be carried out locally or overall performance test, only confirm the overall performance has met the requirements, the energy delivered.
    Some wheeled cranes member relative in prison is a very important component , such as arm , frame , slip girders, axle, with luffing rope hoisting , luffing telescopic cylinder and piston rod . From these components, parts , components, damage caused by the failure often result in serious text Buggy put Gang Here, the repair should take extra care of their cup tie .
