As a company that is routinely called out to service, inspect, and repair overhead cranes and hoists, we’ve put together this list of the five most common problems with overhead cranes so that you have a better understanding of what issues or problems you might encounter during the life of your overhead crane. And most importantly, what you can do to help prevent or mitigate them.

Damage or degradation to wire rope is one of the most common issues that you may experience with an overhead crane system. There are a number of common wire rope problems, including any of the following:The wire rope has jumped out of the reeving system

Many operating conditions can affect the life of wire rope. Bending, stresses, loading conditions, speed of load application (shock load), abrasion, corrosion, sling design, materials handled, environmental conditions (heat or chemical exposure), lubrication, and history of usage will all factor into how long wire rope can stay in service.

The best way to prevent damage to, or failure of, a wire rope is to inspect it prior to each shift. If any evidence of damage is observed, the wire rope should be properly disposed of to prevent further usage.

Also, make sure that the wire rope is properly lubricated. Proper lubrication of the wire rope has two primary benefits:Reduces friction as the individual wires move over each other

An overhead crane that is out of alignment and skewing as it travels down the runway can cause significant stresses and damages to the entire crane system. The problem with a crane that isn’t tracking properly is that over time, forces that weren’t accounted for in the design and installation of the overhead crane cause stresses to the runway beams themselves and also to the tie-backs or building support structures.

A crane that isn’t tracking properly also causes extensive wear to the wheels, wheel bearings, and wheel flanges—as well as premature wear to the motor drives and other equipment.

There are certain signs that your crane may not be aligned properly and is skewing as it moves down the runway. When your crane is in operation, be aware of the following:Loud scraping sounds

If the wheels, wheel bearings, or wheel flanges begin to wear or break down prematurely, it can be an indication that the crane is skewing and not properly tracking down the runway system. Skewing of the crane can cause excessive wear and stress on the wheels, but also on the runway beams and support structures as well.

Wheels tend to wear out faster on a crane that was installed using an existing rail system as opposed to a new installation. Unless the runway has been properly surveyed prior to installation, the runways may be misaligned or the rails may be out of tolerance.

You may also find that pendant controls can become disconnected or pulled out of the hoist. The reason that this can occur is because the operator pulls on the pendant to maneuver or position the crane—especially on jib cranes or workstation cranes. If your controls become unresponsive, you may need to check to see if the pendant became disconnected from the hoist, or have the system serviced and re-wired if any wires become loose.

Not only will regular crane inspections keep you in compliance with sanctioning bodies like OSHA, ASME, and CMAA but it will help keep the crane and hoist equipment operating at top efficiency, help to keep your employees safe, help reduce costly down time, and extend the life of the equipment.

You should receive some type of owner’s manual or maintenance interval book from your crane manufacturer. The manufacturer’s service recommendations are provided based on the duty cycle and capacity of your specific crane, so follow the manufacturer’s recommendations for crane and hoist maintenance, as well as lubrication and inspection intervals.
