Small Micro Compact Tracked Chassis (Specialized for Narrow Working Conditions)

——Provides a reliable mobile platform for confined space operations such as pipelines, tunnels, sewers, chemical tanks, and sewage pools  

**Product Positioning**  

This micro tracked chassis is specifically designed for narrow and highly challenging working conditions, including pipeline inspection, mine tunnel transportation, sewer dredging, chemical tank maintenance, and operations in complex factory areas. Based on engineering machinery special equipment standards (GB/T 25684/ISO 20474), it adopts high-strength structures, modular drive systems, and environmental adaptability technologies to ensure stable operation and safe control in low, rugged, and corrosive environments.

**Core Design Advantages**  

**1. Compact Size and High Mobility**  

- **Ultra-Narrow Body**: Standard width ≤550mm, height ≤900mm (including drive unit), customizable to smaller sizes, easily passes through pipelines with a diameter ≥600mm or 1m×1m right-angle tunnels;  

- **Low Ground Pressure**: ≤20kPa (rubber track version), avoiding damage to soft ground, anti-corrosion floors, or fragile structures;  

- **Ground Clearance ≥180mm**: Optimized chassis geometry layout, capable of crossing 150mm obstacles or 10cm trenches.  

**2. All-Terrain Adaptability**  

- **Multi-Mode Track System**: Offers rubber/steel/polyurethane composite track options, suitable for various surfaces such as gravel, mud, metal grilles, and epoxy floors;  

- **Independent Suspension + Hydraulic Damping**: Four-wheel independent suspension structure combined with oil pressure damping effectively absorbs impact vibrations, ensuring smooth travel on slopes (max 25°) and stepped surfaces.  

**3. Enhanced Environmental Tolerance**  

- **Anti-Corrosion and Explosion-Proof Design**: Main body made of 304 stainless steel or special engineering plastics (optional), key electrical components meet Ex d IIB T4 explosion-proof rating (GB 3836), suitable for flammable and explosive environments such as chemical tanks and oil/gas pipelines;  

- **IP68 Protection Rating**: Fully sealed drive unit and wiring interfaces, supports short-term immersion in water ≤1m or high-pressure washing.  

**4. Precise Control and Safety Redundancy**  

- **Dual-Mode Power Configuration**:  

- **Electric Version**: 48V high-torque DC motor, supports 0-1.2m/s stepless speed adjustment, 8-12 hours of endurance (with intelligent power management);  

- **Hydraulic Version**: Closed hydraulic system, peak output torque ≥1200N·m, suitable for heavy-duty climbing or traction operations.  

- **Multiple Safety Protections**: Automatic torque limitation during overload, tilt alarm, emergency braking (response time ≤0.3s), remote emergency stop interface (supports wireless signal access).
