Reasonable profit and loading one hundred rejection Tools

This article explains wheeled crane repair Fixed lift table , from understanding the phenomenon , determine the cause talk , to determine a repair solution has been
( A ) failure to understand the phenomenon
Crane parts during operation partner suddenly suddenly invaded or mountain now crawling , vibration, abnormal temperature rise and smoke , smell, sound, meter pointer jump swing , oil spills, leaks , leaking , leakage , control When the crane when a fault occurs , some phenomena can clearly be observed , and some hidden imperceptible . Maintenance and inspection must be carefully observed in order to find the real source of it down .
( Two ) analyze the cause
Yi Gu array of pallet truck as the basis, in accordance with the rules and guns corporate failure by practical experience, control apricot find relevant information , list of similar phenomena whose failure may occur for various reasons , sub- Xin structure and [ : operating principles , discussed to determine the real cause of the malfunction .
( Three ) to determine demolition site
Failure Analysis is based to determine what caused the failure of the parts, and the parts of the system to determine the demolition inspection of the site.
For determining the dismantling of the site, shall give rise to the possibility of failure , to determine the sequence of disassembly
Unloading operations, except in compliance with - ' suits mechanical disassembly required outside, but also pay attention to the following questions:
1 . Preparation for traveling to run dry stable frame bracket pad Zhao , prohibited the use of leg support frame.
2 . Standby system at ten non-working state
Yi closed engine , release the hydraulic system and pneumatic system 44 residual Osteoform . In order to avoid injury.
3 . Reasonable profit and loading one hundred rejection Tools
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.

set the winch for small and medium-bridge from the physical machine

Erection of masts, the mast should be pre-wind cable rope bindings temporarily close the roof truss bottom chords on the mast until the mast was hanging to determine the location immediately after the entire wind cable rope fastened on top of the mast and tighten the ground, such as individual wind cable rope lift after the force has stayed truss chord or circumstances, the application temporarily wind cable hove live mast, fixed wind cable rope adjusted to the appropriate location, and then release the temporary wind cable wire.
⑤ hung pulley block, set the winch for small and medium-bridge from the physical machine, and can be hung two pulley electric lift table, with two hoisting winches, hoist mast set the location and distance from the center is greater than the length of the mast, winches available fixed column within the plant roots, but should be tied at the wood and other protective pads.
(2) group on the carts, loaded trolley traveling crane girders, the car shipped to the lifting position for assembly, carts group finished, the car is placed on a trolley hand pallet trucks, and carts tied securely.
(3) bundled beam carts for less than 50t overhead crane, just hang two pulley block, generally using a cross-tied method, the method is: the mast lug toward the direction of the end beam bridge crane system hang hanging pulley block , running rope through the top of the mast mast fixed pulley down to the bottom along the guide pulley toward the winch. Run rope using sequential method. In the side of the cart with a rope tied to the beam cross-licensing to go through two openings platen bundle, so that tied rope was tapped: "∞" shape, commonly known as "8"-shaped bundle method, as shown in 7-9.
When the lack of effective height of the mast, can be boom EMU binding movable trolley beam inside the carts in the top surface of the beam erection carts beams, ends binding slings, sling around the underside of the beam from moving into a tie tackle.

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 .
