Planned maintenance overhead crane

Scheduled maintenance  overhead bridge crane  is the date specified in the plan within the crane for maintenance and repair. Its purpose is to prevent the crane from excessive wear or accidental damage, promptly eliminate hidden equipment to enable the crane often in good technical condition, to ensure the safe operation of the crane, to stop in the shortest possible time and maintenance costs minimally crane maintenance work done in order to achieve increase savings and reduce costs. Planned maintenance can be divided according to conventional small repair, repair, overhaul.

1 small repairs
Minor repairs in the organization's mission is to exclude the operation and maintenance of the fault found by the mechanical repair and replacement parts to restore normal operation. Minor repairs are local repairs, spending a short time, what a bad repair anything, its maintenance should include: the whole  overhead gantry crane  rotating part of the mechanical and electrical equipment parts and metal structural parts to conduct a comprehensive inspection.

For all lubrication points according to their lubrication cycle for cleaning, oil lubrication.

Overhauling of individual parts, replacement or repair.

Certain electrical components for repair or replacement.

For electrical and mechanical parts have broken the trend, the content should be as predictable repair technical preparation work so that in the next cycle repair processing.

(2) the repair
The repair is partially decomposed crane, repair, or replacement of worn parts, crane geometry correction and precision, keeping the crane process performance. In addition to its maintenance content includes the entire contents of minor repairs, but also includes:

Work frequently load large electromechanical components dismantling, cleaning, repair or replacement and lubrication.

According to plan on the technical preparation of the electro-mechanical components to be replaced.

Electrical wiring of the bridge gantry crane  to conduct a comprehensive inspection, replacement of some aging wiring and damaged electrical components.

3 Overhaul
Overhaul is all disintegrated, checking each component disassembly, repair repairable parts, replacement parts or individual can not repair parts, requiring crane overhaul at or near the factory with the technical standards and mechanical properties. Its maintenance should include:

All part of the body decomposed bodies, including reducer, coupling, drum set, wheel set and extract device and other components, replace damaged and had to be scrapped for parts, re-assembly after cleaning and lubrication, replacement wire rope , agencies brake and open the unit.

The motor should be decentralized agencies, drying, assembly and lubrication, replacement of badly damaged motors. Replacement brake opening device agencies; replace damaged bodies cam controller; protection cabinet overhaul or replacement protection cabinet; replace all line connections, re-wiring installation; replacement lighting signaling system control board.

Metal structural parts, right down deflection has occurred or lateral bending of the main beam is corrected repaired and reinforced; All of the entire crane clean and painted two times to protect them.

The overhaul of the  bridge crane  to be debugged, and then press the static and dynamic load test procedures for identification, after passing into production use.
