Description
The Hitachi Sumitomo SCX3500-3 carrier roller is a lightweight yet heavy-duty undercarriage component engineered for the 350-ton capacity lattice boom crawler crane. Positioned along the upper track frame, these rollers support the track chain on its return path, preventing sagging and maintaining proper alignment during crane travel.

Maintenance Guidelines
Regular inspection of carrier rollers is essential for undercarriage longevity. Check for:
Unusual noises during operation
Freedom of rotation — the roller must turn freely by hand
Wobble — must turn true with minimal side-to-side or up-and-down play
Signs of rust — indicating water entry into bearings
Grease leaks — indicating faulty seals or water contamination
Any of these conditions indicate bearing damage, and the roller should be disassembled for further inspection with new bearings installed as needed.
