Excavator track pads are not selected by machine size alone. A mini excavator and a heavy excavator can both use polyurethane pads, but the width, mounting arrangement, load and working conditions are very different.
VectorMax supplies widths from 230mm to 800mm for a broad range of steel-tracked equipment. The correct starting point is always the actual steel shoe fitted to the machine.
What changes as excavators get larger?
Track-shoe width usually increases with machine size, but width is not the only change. Larger machines apply more load to each contact point and can have different grouser profiles, clearances and hardware requirements.
Compact machines may work around driveways, landscaping, utilities and finished residential areas. Mid-size excavators often move between general construction, roadwork and commercial sites. Heavy excavators may work on demolition, infrastructure and large hardstand areas where load and travel forces are much higher.
Brand and model are useful, but not enough
Potential applications include equipment from Caterpillar, Kubota, Takeuchi, Bobcat, Case, Yanmar, Komatsu, Volvo and other manufacturers. The machine model helps narrow the search, but it does not replace physical measurements.
The same model can be supplied with different track-shoe options. A used machine may also have replacement chains or shoes fitted by a previous owner. For that reason, a fitment check should include the exact model, shoe width and photographs of the mounting area.
Compact and mini excavators
Mini excavators frequently work where surface access matters: landscaping, driveways, paving, small commercial sites and indoor demolition. Their smaller size does not make every pad interchangeable.
Check:
- The exact steel-shoe width
- Whether pre-drilled holes are present
- The grouser shape if considering clip-on pads
- Clearance around the shoe and track frame
- The number of shoes per side
Mid-size excavators
Machines in the middle of the range often perform the widest variety of work. One week may involve trenching on soil; the next may require travel across concrete or asphalt. This mixed use makes mounting style an important decision.
A bolt-on arrangement can suit regular paved work when the shoe has matching holes. A clip-on arrangement may suit a machine that needs pads for selected projects and has a compatible shoe profile.
Heavy excavators
For heavier equipment, confirm more than nominal width. Pad construction, mounting security, available clearance and working load must be appropriate. Tight turns and long travel on abrasive ground place substantial stress on both the polyurethane and hardware.
How the job changes the choice
A machine used mainly on asphalt and concrete has different needs from one that only crosses a finished area occasionally. Consider how often the pads stay fitted, the distance travelled, turning space, surface temperature and the amount of sharp debris.
Rental fleets and contractors should also consider how easily operators can inspect the mounting system between jobs. A reliable maintenance routine is part of the product choice.
Information an expert needs
If you cannot identify the correct pad, send:
- Manufacturer and exact machine model
- Steel track-shoe width in millimetres
- Top, side and underside photographs of one clean shoe
- Mounting-hole measurements where present
- Number of shoes on each side
- A brief description of the normal work surface
Use the How to Measure page to collect these details. If the model does not appear in the finder, contact VectorMax; a specialist can help compare suitable products without relying on the model name alone.
