Wheel alignment crucial to ensuring end-carriages last longer

End-carriages are key subassemblies in overhead cranes, and customers are advised not to attempt their own end-carriage assembly using individually sourced wheel blocks, as wheel alignment is critical to ensuring the longevity of these ‘feet’ of overhead cranes, says crane and hoists specialist company Condra MD Marc Kleiner. End-carriages support the girders and hoists, and move them along the rails. Wheel wear as a result of misalignment of the wheels at each end of the end-carriage and/or distortion of the rails caused by heat can result in excessive end-carriage maintenance costs.
