A vertical lift cylinder solves problem for an assembly company that installs front and rear tire
assemblies (tire, rim with hub, and wheel weights) onto the axles of farm tractors and harvesters.
Various tire sizes range from 36 to 94 inch diameter and 18 to 49.5 inch width, with a weight up to
6,000 pounds. The problem was that the tire assembly needed to be orientated such that the hub
centerline is parallel to the centerline of the axle. There is a close fit between the hub ID and axle
ID. The tire assembly must be rotated to align the hub key with the axle keyway. Thus, the tire
assembly is lifted, pitched, swiveled, and rotated during installation onto the axle. An overhead
hoist, with a sling or C-frame lifting device, was used for lifting; however, this method lacked
control and safety.
