I. Core Turning Radius Parameters

Tracked carriers primarily use differential steering / pivot steering, and do not have the fixed turning radius concept of wheeled carriers. Key indicators:

Minimum Turning Radius

• Pivot steering (center-point turning): Radius ≈ 0, capable of 360° in-situ U-turn – a core advantage of tracked chassis.

• Models with width restrictions / body protection: Minimum radius ≈ 0.3–0.8 m.

Recommended Safe Turning Radius

For heavy-duty / high-speed driving, to prevent rollover and track derailment, a safe turning radius of 1.5–3 m is recommended.

II. Key Maneuverability Parameters

Steering Modes

• Civil engineering models: Bilateral track differential steering (forward/reverse rotation enables pivot turning).

• Large heavy-duty models: Some equipped with hydraulic power steering for smoother control.

Maneuverability vs. Body Dimensions

• Small walk-behind / mini models (0.5–1.5 t): Body length 1.8–2.8 m, flexible passage in confined spaces, field ridges, and sheds.

• Medium models (2–5 t): Body length 3–4.5 m, suitable for construction sites and mountain forest access roads.

• Large models (6–12 t): Body length 4.5–6 m, reduced steering flexibility – recommended for open sites only.

Auxiliary Maneuverability & Passability Indicators

• Minimum ground clearance: 180–400 mm, avoids bottoming out when overcoming obstacles.

• Track contact length: Shorter length = easier pivot turning; longer length = better driving stability.

• Body width: Standard 0.8–1.8 m; narrow-body models can access orchards and narrow lanes.

III. Maneuverability Limiting Conditions

• Heavy-load state: Sharp pivot steering is prohibited, as it may damage tracks and cause rollovers; use a larger turning radius.

• Soft / muddy ground: Pivot steering easily digs ruts and causes sinking; gentle small-radius turning is recommended.

• Sloped terrain: Lateral steering is strictly forbidden; only straight driving + gentle small-radius turning along the slope is permitted.

• Track tension: Excessively loose tracks reduce steering response; overly tight tracks increase wear and steering resistance.

IV. Comparison with Wheeled Carriers (Summary)

Tracked carriers have far superior maneuverability to equivalent wheeled carriers:Wheeled models typically have a minimum turning radius of 3–6 m, while tracked models can perform 0-radius in-situ U-turns.They are better suited to confined scenarios such as narrow construction sites, mountain forests, and agricultural sheds.
