Why the Bottom Roller Matters for the BM500
The Kobelco BM500 crane is a 50-ton lattice boom crawler crane. The machine’s bottom rollers (lower or track rollers) carry the weight of the entire machine and its load moment.
Signs Your BM500 Bottom Rollers Need Replacement
To prevent a serious malfunction that can result in the separation of tracks, monitor your BM500 crane undercarriage. If you see any of the following symptoms, replace your bottom rollers immediately:
Turning Seizure: The roller fails to turn freely once the machine is raised.
Worn Flanges: The roller-retaining flanges become worn, forming a knife edge.
Oil/Grease Leakage: Grease leakage from the side seals signals an impending bearing failure.
