Familiarity with the maintenance and repair of cranes

Maintenance and repair of cranes is one of the most important issues in industrial factories and construction workshops. The meaning of maintenance and repair is the set of operations and activities that are carried out in order to maintain, control and increase the useful life of equipment, facilities and devices. Maintenance and repair programs help the management to better plan and monitor affairs, and by using them, you can make maximum use of the available facilities.

The general principles of preventive maintenance and repair of cranes

Maintenance and repair programs are a set of methods, forms and instructions that deal with the planning of corrective or basic maintenance and repair, how to supply spare parts, and planning to supply the necessary manpower. The maintenance and repair program should be carried out regularly according to the instructions of the crane manufacturer. Of course, it should be noted that what is proposed by the manufacturer is a preventive maintenance and repair program that is carried out periodically, and the crane may need other repairs based on the inspection schedule.

In this section, general issues regarding preventive maintenance and repair that are common to different types of cranes are discussed. All maintenance, repair and replacement items must be reported in a special notebook and approved by the foreman or repairman. Maintenance and repair documents must be properly filed. The personnel of the maintenance and repair department must have sufficient knowledge about the machines and be aware of the dangers of the work environment.

Crane repair safety tips

1. The required equipment should be placed in the repair area regularly, and the repair area should be separated from the surrounding area by a rope or fence, and only repair personnel should enter this area. 2. If the movement or fall of any other part of the crane causes danger during implementation, repair and assembly, that part must be restrained or strengthened. 3. If the engine is not necessary for repairs, it should be turned off. 4. When the engine is on or the driver has access to the control levers inside the cabin, under no circumstances should people be placed under the parts under repair or on the parts without the coordination and knowledge of the driver. 5. All control levers must be released and ensure that the levers are not activated unintentionally. 6. The crane must be turned off and the switch removed to ensure that the crane is inactive. If more than one switch is available to the personnel, a warning sign should be placed inside the cabin so that others do not turn on the crane. 7. Warning signs must be installed outside the cabin and on the crane to indicate that the crane is being serviced and should not be used.

If a part of the boom has suffered an accident that impairs the performance of the boom, the work must be stopped so that an expert repairman certifies that the necessary repairs have been made on the part and the continuation of work is unimpeded. Note: Carrying out repairs and changes on the crane boom is a specialized work that requires training and experience. Before repairing the boom, contact and coordinate with Sharifi workshop crane repairs.
