Overhead cranes are one of the most vital and key machines in manufacturing industries, warehouses, industrial sheds and factories. By moving heavy loads, these equipments play an essential role in maintaining the rhythm of production, the safety of the work environment and reducing the time of the processes. Due to the very high working pressure on these devices, mechanical wear and electrical errors are completely normal. Therefore, the subject of "overhead crane parts repair" and access to a reliable authority for "selling crane equipment across the country" has become one of the main needs of industry managers. With years of brilliant experience, Hosseini Ceiling Crane Group has been able to provide a safe and reliable platform for all industries in the country, as a specialized center for repairs, overhauls and direct supply of all kinds of spare parts.
In this article, we intend to comprehensively review the types of mechanical and electrical parts of overhead cranes, standard troubleshooting and repair processes, key points in purchasing equipment, and the role of technical expertise in increasing the lifespan of these machines.
The importance of maintenance and repair of overhead crane parts
Overhead cranes are constantly affected by mechanical stresses caused by load weight, continuous vibrations and environmental conditions such as dust, heat and humidity. Any small malfunction of the parts can lead to irreparable accidents and heavy financial losses. The process of repairing overhead crane parts includes accurate identification of damage, reconstruction or replacement of worn parts with original equipment and final test under standard load.
Preventive maintenance and regular periodic services minimize the risk of sudden stoppage of the production line. Using experienced technicians who are familiar with international standards such as CMAA and DIN, the Hosseini overhead crane complex performs the repair services of overhead crane parts with the highest engineering precision to ensure the smooth and safe operation of the structure.
Main and specialized parts in repairing overhead crane parts
A ceiling crane system consists of two major mechanical and electrical parts. Each of these parts requires special technical knowledge for troubleshooting and repair.
Repairs of mechanical systems and power transmission
The mechanical part is responsible for bearing and moving the load directly. Parts of this section have the highest depreciation rate due to constant wear:
- Crane Gearbox: Gearboxes perform the task of adjusting speed and torque. Problems such as oil spillage, gear corrosion, broken teeth, and unusual noises should be addressed immediately. In the repair of overhead crane parts, replacing damaged bearings and shafts with hardened parts is of great importance. Towing wire and drum: Towing wire must be continuously inspected for broken strands, crushing, rust and twisting. The grooves of the drum are also corroded due to friction, which require precise machining or replacement.
- Hooks and pulleys: The lifting hook is the beating heart of the crane. Any deformation, excessive opening of the hook opening or hairline cracks will cause the load to fall. Non-Destructive Tests (NDT) such as Magnetic Particles (MT) and Penetrating Liquids (PT) are performed at Hosseini Overhead Crane Center to ensure the health of the hook.
- Mechanical brakes and pads: The brake system must be able to stop the rated load at any height. Pad looseness adjustment, replacement of worn springs and brake magnet adjustment are part of the vital maintenance process.
- Wheels and longitudinal and transverse rails: Wheel rim wear, misalignment and wheel bearing failure cause severe vibration and crane bridge deviation.
Troubleshooting and repairs of electrical and control systems
The complexity of modern electrical circuits requires electrotechnical expertise and precision instruments:
- Electric motors (lifting and motion motors): Coil burn, rotor failure, magnetic brake damage and overheating are common problems of motors. Re-winding with high insulation class and dynamic balance is required in the specialized repair process.
- Power Panels and Inverters (VFD): It is very common to use remote control drives for smooth and shock-free movement. Adjusting inverter parameters, replacing damaged contactors, thermal relays and fuses are done with the highest precision in Hosseini's ceiling crane workshop. Repairing remote electronic boards and replacing joysticks are among the most requested services.
- Bus and power supply lines (C system and busbar): Sweepers, coals and festoon cables wear out over time and cause phase failure or voltage drop.

A step-by-step guide to preventive maintenance (PM) of overhead cranes
To reduce the need for major and costly repairs, a regular preventive maintenance program is recommended:
- Daily checks: Before starting the shift, the operator must check the operation of the limit switches, alarm, the health of the brakes and the absence of unusual sounds.
- Periodical lubrication: The gears, bearings, wire ropes and moving joints must be lubricated with suitable grease and oil according to the lubrication table provided by the manufacturer. be lubricated.
- Monthly inspection of connections and structure: Structural bolts and nuts, condition of welds, health of rails and electrical connections must be controlled by the technical team.
- Annual load test: The crane must undergo static load test (125% rated load) and dynamic (110% rated load) once a year and receive a health certificate.
If during the inspections you encounter things such as asymmetric wear, oil leakage from the gearbox or loss of lifting power, the experts of the Hosseini Ceiling Crane Center are ready to be dispatched to the site and provide fast troubleshooting and repair services.
