When to do overhead crane maintenance? This is a particularly important topic. Among them, the stable operation of the bridge crane is certainly important, but more important is the daily overhead crane maintenance and inspection work to ensure the safety of the operators and people around the equipment. Next, this article will help you understand what the daily overhead crane maintenance and inspection involve. If you don't know how to maintain an overhead crane, then this article will be your ideal guide.
What Is An Overhead Crane?
The overhead crane is mainly composed of the main beam, end beam, lifting trolley or electric hoist, electrical system and other main structures. Because its two ends are located in the concrete column or metal support, the shape is like a bridge, so it is called an overhead Travelling crane. Mainly used in production workshops, factories, construction sites, petrochemicals, warehousing and logistics, etc.
When To Do Overhead Crane Maintenance?
While maintaining efficient operation, overhead cranes must also ensure the safety of operators and people around the equipment. Therefore, daily inspections and regular maintenance are particularly important. Any workplace that uses bridge cranes to move materials should be equipped with an overhead crane maintenance and inspection system table. This can effectively extend the service life of the bridge crane while ensuring the safety of the operator's life and reducing the losses caused by factory downtime.
The overhead cranes operator people can be maintained and inspected according to the following conditions:
Daily maintenance: Before and after each use, check whether the key components such as wire rope, hook, brake, etc. are normal. Observe whether there is any abnormal noise or vibration during operation.
Regular maintenance: Based on the daily lifting load and usage time, check the lubrication system weekly or monthly to ensure the lubrication of bearings, gears and other components. And test whether safety devices such as limit switches and emergency stop buttons are effective.
Annual comprehensive inspection: Professional technicians conduct comprehensive inspections, including the structural strength of the main/end beams, electrical systems, mechanical transmission and other parts. Load tests are also performed to ensure the operation of the crane under rated load.
Maintenance under abnormal conditions: If any abnormal conditions such as unusual noise, vibration, brake failure, etc. are found in the equipment, it should be stopped immediately and inspected by professional technicians.
Overhead Crane Inspection Checklist
| Item | Contents | Inspection Cycle |
|---|---|---|
| Metal Structure | Whether the bridge deck has cracks, deformation, or corrosion. There is any crack in the main material and the welding area. The bolts are tight and reliable. Are there any cracks, deformation or corrosion in the structural parts. |
Before and after use |
| Lifting mechanism | Check the drum, bearings, pulleys, wire ropes, hooks and other components for abnormalities such as cracks, deformation, corrosion, etc. And Check whether the bolts and nuts are loose. | 1 time every 1 months |
| Travel mechanism | Check the coupling, bearings, wheels, motors, brakes, reducers and other parts for wear, as well as any abnormal conditions such as unusual noises and wheel jumping. | 1 time every 1 months |
| Rail | Check whether the rail is loose, disconnected, deformed, cracked, or has other abnormalities. | 1 time every 3 months |
| Electrical control system | Check whether the motor, bus bar, collector, cable, control switch, and other components are damaged, deformed, or corroded. | 1 time every 1 months |
Notice: The inspection period can be adjusted according to the actual usage frequency and environment.
Overhead Crane Maintenance Checklist
| Maintenance category | Specific maintenance content | Maintenance Frequency |
|---|---|---|
| Wire Rope | Clean foreign matter from the surface and apply grease. | Semi-monthly |
| Safety protection device | Test whether the reducer, limiter and overload protection device are operating normally. | Monthly |
| Gear and wheel sets | Check the degree of wear and apply grease. | Monthly |
| Electric Motor | Clean the surface impurities and check whether there is leakage due to wear and tear. | Monthly |
| Track maintenance | Clear the surface debris and check whether there is any blockage at the connection. | Semi-monthly |
| Control System | After daily use, clean the remote control or the driver's cab and check the dexterity of the buttons. | Every day |
| Environmental adaptation | For overhead cranes operating in some special environments. | When the seasons change |
Notice: The maintenance period can be adjusted according to the actual usage frequency and environment.
Overhead Crane Preventive Maintenance Schedule
It's also vital to perform preventative maintenance by professional technicians regularly so that any potential issues can be caught before they develop into major problems requiring expensive repairs or replacements. Doing so will save time, money, and effort in the long run by preventing unnecessary downtime due to equipment failure or malfunction. Additionally, these checks can ensure that all safety features are functioning properly and reduce the risk of injury from malfunctioning equipment in the workplace.
Overall, the overhead crane maintenance should follow the principle of "prevention first, regular inspection" to ensure that the equipment is always in the best operating condition. A reasonable maintenance plan can not only improve work efficiency but also greatly reduce the risk of safety accidents.
