Project overview
The long-travel units of the customer's in-house-built 40-ton and 50-ton cranes showed wheel wobble and rail rubbing. ONVALLA's team surveyed the site and measured the runway span and the crane span, then installed guide rollers on the long-travel units to set the span correctly. Wheel wobble and rail rubbing were significantly reduced.
