An easy crank handle allows for easy lifting and lowering while ball bearing casters let you move the lifted object hassle-free. But the lifespan of a wheel depends on more than hardness alone. If wheels take 10 years to wear a quarter of an inch, you may have little cause for concern. Overall Span - The total length of the horizontal I-beam that supports the load. Height can be adjusted by two people, or by a single person if using the optional AHA-KIT ratcheting come-alongs.

Commonly, they are the first crane parts to show the effects of crane problems, such as misaligned rails. Tread - The distance between the legs of the support framework at each end of the gantry crane. 
For most crane wheels, medium-carbon steel is the most commonly employed material, due to its wide availability and lower cost. Over the life of the crane, and dependent on how far along the runway the crane travels during normal operations and cyclical loads handled relative to crane capacity rating, the wheels and the rail wear.
At the point where the wheel tread hardness breaks through to the softer wheel material, the wheel then no longer skids when it should, moving from the higher to the lower diameter and the wheel engages the rail head and rides the flange into the side of the rail head.

On the other hand, crane wheel flanges should not be hardened.
- high to provide a sturdy overhead lift point to lift car engines, heavy machinery or equipment. As a general rule, the greater the carbon content of steel, the greater the hardness potential. Not for lifting -, Aluminum Gantry Cranes With Pneumatic Wheels, Set of 2 Ratcheting Come Alongs - Allows for one-person height adjustment.

Closing this post, I have a few things to know, and remember: As always, contact your Crane Doctor Eric Brown at Engineered Lifting Systems Contact if you need anything!
Thanks to advances in heat treating technology, the hardness of crane wheels made with medium-carbon steel has been increasing. Casters are always matched to the load capacity of the crane.
Gantry cranes have certain specifications that you should be aware of as you consider adding them to your operations. gtag('config', 'AW-1000833296/pm8bCOmnjaYBEJCCnt0D', {
AHA-4Aluminum Gantry Cranes with Pneumatic Casters are built to order with an estimated lead time to leave the warehouse of 40 business days. On the other hand, crane wheel flanges should not be hardened.
At the point where the wheel tread hardness breaks through to the softer wheel material, the wheel then no longer skids when it should, moving from the higher to the lower diameter and the wheel engages the rail head and rides the flange into the side of the rail head.
