Heat shirnk steel tyres to crane wheel hubs.

We have facilities to heat shrink tyres to hubs under controlled conditions to prevent the tyres heat treatment to be influenced. Normally we get the tyres nominal bored and then machine them to the required interference for the heat application and fit to the correct requirement.

See this video of how we do it.    Fitting steel tyres to wheel hubs
