Crane shafts and wheel axles
Travel shafts, keyed axles, coupling ends.
A bent travel shaft shows up as a crab that walks. We reverse-engineer worn axles from sample or drawing and match steel grade and heat treatment.
When it fits
A walking trolley, a noisy bearing or a coupling that threw a key usually starts here. Send the sample if the drawing is gone.
Duty and steel
Steel grade and heat treatment follow the cycle, not a mild bar from the nearest market.
Interface
Keyways, splines and bearing seats are held to the wheel-block or trolley that will receive them. A shaft that is only ‘close’ walks the crab.
