How to select a suitable track roller for your excavator/bulldozer/loader ?
Provide us the track roller part number or excavator model if you know it. If you don't know it, how to select a right track roller?
Tonnage matching:
1-3 ton micro excavator: need 4-6 pcs of track roller, single wheel weight ≤ 15kg;
5-8 ton small excavator: need 6-8 pcs of track roller, single wheel weight 20-35kg;
15-25 ton medium excavator: need 8-10 pcs of track roller, single wheel weight 40-70kg;
30 ton and above large excavator: 10-12 pcs of track roller, single wheel weight ≥ 80kg
Track pitch matching: The track pitch and tread width of the supporting wheels must be consistent with the track plate pitch and width - incorrect track pitch can easily cause derailment, narrow tread can easily fracture the track plate, and wide tread can increase frictional resistance
Chassis structure: Match the installation hole positions, axle diameters, and center distances of X-shaped and H-shaped chassis to avoid installation failure
