Project Selection: Crawler vs Wheeled — Core Judgment Criteria

1. Check ground conditions (1st priority)

• Soft, muddy, mountainous, or unpaved ground → choose crawlerReason: low ground pressure, no sinking, strong grip, high stability.

• Hardened pavement, urban roads, residential areas, factory areas → choose wheeledReason: no road damage, easy to drive, no site destruction.

2. Check operation mode (2nd priority)

• Fixed site, long-term work, heavy-duty earthwork, mining, infrastructure → choose crawlerReason: high traction, high efficiency, strong continuous operation.

• Multi-site work, frequent transfers, short-distance movement, municipal scattered projects → choose wheeledReason: road-legal, fast speed, no trailer needed for transfer, high mobility.

3. Check workload (3rd priority)

• Heavy-duty digging, hard soil, rock, frequent crushing → choose crawlerReason: good stability, no overturning, rugged and durable.

• Light-duty work, loading/unloading, landscaping, municipal repair → choose wheeledReason: flexible, fast, sufficient capacity.

4. Check access and environment

• Wilderness, inside construction sites, no traffic restrictions → crawler

• Urban areas, highways, road driving required → wheeled

Ultimate one-sentence memory formula (memorize this only)

• Ground: Soft/rough ground → crawler; hard pavement/urban areas → wheeled.

• Work: Long-term heavy-duty → crawler; short-distance transfer → wheeled.

• Efficiency: High pure digging efficiency → crawler; mobility & flexibility → wheeled.
