Features:
Mobility: Uses a crawler chassis, similar to a small tank’s movement system.
Stability: Large ground contact area, low pressure, less prone to sinking, ideal for soft or uneven terrain.
Flexibility: Can pivot in place, suited for tight spaces (e.g., indoors, warehouses).
Ground Protection: Tracks distribute pressure, minimizing damage to hard surfaces (e.g., tiles, concrete).
Speed: Slow movement, best for short, precise shifts; long distances require trailer transport.
Applicable Scenarios:
Soft/Muddy Ground: Construction sites, unhardened land, sand, snow.
Indoor Settings: Warehouses, factories, gyms where floor protection is needed.
Complex Obstacle Terrain: Areas with pipes, pits, or debris.
Precision Positioning: Stage setup, interior decoration requiring frequent fine adjustments.
Limitations:
Not suited for long-distance travel or frequent site changes.
Less efficient on flat, hard surfaces compared to wheeled models.
Features:
Mobility: Equipped with large pneumatic tires, four-wheel drive, and high ground clearance.
Terrain Capability: Handles steep slopes, gravel, grass, and other outdoor rough terrain.
Speed: Faster travel, capable of self-transfer between sites (e.g., construction zones).
Load Capacity: Typically higher, suitable for carrying more tools or personnel.
Terrain Adaptability: Balances mild off-road and paved surfaces, but may slip on very soft ground.
Applicable Scenarios:
Outdoor/Mountain Work: Power line inspections, wind farm maintenance, forest firefighting.
Mixed Terrain Sites: Construction areas with paved roads, slopes, and ditches.
Long-Distance Needs: Projects requiring quick shifts between work points.
Harsh Weather: Some models offer anti-slip and weather-resistant features.
Limitations:
Tires may sink in mud or sand, requiring additional road-laying measures.
May damage indoor or delicate surfaces (e.g., wood floors).
Scenario Comparison Summary
| Scenario Need | Crawler Preferred | All-terrain Preferred |
|---|
| Ground Type | Soft, muddy, sinking-prone | Paved roads or mild off-road |
| Movement Frequency | Short, precise positioning | Long-distance, fast transfer |
| Space Constraints | Narrow indoor spaces | Open outdoor areas |
| Ground Protection | Floors needing minimal damage | No special protection needed |
| Terrain Complexity | Debris, pits, obstacles | Slopes, gravel, grass |
Selection Advice:
Choose Crawler: Indoor decoration, soft ground construction, tight spaces, high ground protection needs.
Choose All-terrain: Outdoor inspections, mountain projects, mixed-terrain transfers, speed and passability required.
Final choice should also consider work height, load capacity, and environmental factors like humidity (e.g., crawler rust prevention).
