For cranes to be used in normal and heavy service, you should rest assured to get the crane inspected periodically by a qualified and certified inspector. The periodic inspection of the crane should be inclusive of the following:
- Cracked, corroded, and deformed equipment
- Loose rivets and bolts
- Worn out and cracked drums and sheaves
- Wear and tear of the braking system, parts, pawls, linings, and ratchets
- Excessive chain stretch and worn out chain drive sprockets
- Distorted, cracked, and worn out parts of the crane inclusive of bearings, pins, gears, shafts, rollers, clamping, and locking devices
- Signs of pitting on electrical apparatus or deterioration of pushbutton stations, limit switches, and controller contractors
- Improper performance of electric, diesel, gasoline or other power-plants
- Non-compliance of safety requirements
- Considerable inaccuracies of wind, load, and other indicators
In the event you own a crane that has been frequently used or not used at all for the past month but seldom used of the past six months, you would be required to perform a functional and periodic test inspection before its next usage. Similar regulations would apply provided the crane has not been used for the past six months to a year.
It would be pertinent to mention here that the manufacturer or supplier of your overhead crane would need additional inspections at different intervals. The user manual of the crane would list these needs. Therefore, you should keep a copy for your reference needs.
You may consider it time-consuming and expensive to follow the requisite inspections for the overhead crane. Nonetheless, these safety and maintenance checks would be relatively cheaper to the insurance premiums and legal fees that you may have to pay provided someone on your team has been injured due to the inspections that never took place. The website https://www.etihadcranes.com/products/electric-chain-hoist-entertainment insists on a non-qualified person should be abstained from performing the inspections.
