Cranes are incredibly robust pieces of industrial equipment. For instance, a tower crane can lift up to 18 metric tons, or 39,690 pounds, roughly twice the weight of a school bus. Despite their strength, cranes require occasional repairs to maintain their integrity. A malfunctioning crane is a significant safety risk to construction workers and passersby alike.
Indicators of Crane Repair Needs
To minimize the risk of crane service issues, regular inspections by a qualified crane inspector are essential. However, problems can still arise between inspections, so it's crucial to watch for these signs:
- Damaged Chain Links Heavy lifting can wear down your crane’s chain. Links may break or become crushed, which is harder to detect but equally dangerous. Broken or crushed links compromise the crane and hoist structure. If you notice any damaged links, contact a crane repair service immediately for replacement or repair.
- Worn Pads Cranes use various pads to absorb movement forces, but these can wear out over time. If your crane is noisier than usual or its movements are less smooth, worn pads might be the culprit. Address this issue promptly to avoid further damage.
- Rusty Parts Like any metal equipment, cranes can develop rust, particularly in humid environments. Joints, wires, bearings, and other moving parts are especially susceptible. Rust weakens crane components over time, potentially leading to dropped loads. If you spot rust, have a specialist replace the affected parts before corrosion worsens.
- Bent Hooks Improperly balanced loads can bend or crack a crane’s hook. A bent hook may fail under future loads. Inspect the hook after each use for any signs of bending or cracking and call a repair specialist if needed.
- Dry Ropes Ropes can dry out without regular lubrication, especially under extreme temperatures and heavy loads. Dry ropes may stretch or crack, posing safety risks. If your ropes appear dry, frayed, or worn, contact crane repair experts. Lubrication might help, but often ropes will need replacement.
- Cracked or Loose Parts Thoroughly inspect your crane for any cracked or loose parts, including both large components like the boom and small ones like bolts, pins, and rivets. Even tiny parts are crucial for maintaining the crane’s structure. Tighten or replace any loose or cracked parts immediately.
- Worn Brakes and Clutch Similar to a vehicle, the brakes and clutch system of a crane must be in good condition. Worn brakes or clutch components can make the crane unsafe to control. Relining the brakes can enhance their lifespan and performance. Additionally, you might need new brake parts like coils, friction discs, shoes, pads, and anchor plates. A crane specialist can diagnose and address brake failures and necessary repairs.
Preventing Crane Issues
Being vigilant about these common crane maintenance problems can help you avoid dangerous issues like broken parts or dropped loads. All crane operators should report even minor problems immediately. Additionally, avoid overloading the crane, as this can jeopardize its integrity and worker safety. Always adhere to the crane’s loading specifications and carefully secure each load.
