Birdcaging, corrosion, abrasion, and extreme wear are a few of the problems that can affect wire rope on an overhead crane. The best way to prevent damage or failure is to inspect your wire rope regularly.
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:
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.
These types of stresses can result in:
End Carriage Wheels are components of overhead cranes that can require frequent maintenance, replacement, or adjustment. Throughout the course of a crane’s life, the wheels will naturally wear down due to normal use of the crane and will need to be replaced.
Wheels can be made of a variety of materials, including polyurethane for gantry cranes, alloys, low-carbon steel, or medium-carbon steel. The more carbon in the steel, the harder the wheel will be. There are also methods of heat-treating that can be used to increase the hardness of a wheel—increasing the service life and load capacity of the wheelsIf 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.
