The 3-ton crawler spider crane is a heavy-duty mini lifting machine that balances an extended operating radius with exceptional terrain adaptability. Powered by an innovative dual-power system featuring a robust Changchai three-cylinder 14.7 kW diesel engine and an electric motor, integrated with a 6-section high-strength manganese steel telescopic boom and an efficient hydraulic drive system, it delivers superior performance with a maximum lifting height of 10.8 m and a maximum operating radius of 10 m at a lightweight self-weight of just 2.7 t, perfectly balancing power output with high productivity for heavy-duty tasks. With an overall width of only 0.8 m, its non-marking widened rubber tracked chassis allows it to easily pass through narrow access routes and drive directly into indoor or space-restricted core job sites.
This equipment is widely applicable to high-rise glass curtain wall installation, multi-story steel structure erection, power station electrical maintenance, municipal dam projects, and equipment repositioning inside space-constrained factory workshops. Its 3-stage outrigger system—featuring manual extension and independent hydraulic adjustment—ensures precise leveling and stable support on complex terrains such as steps, slopes, or uneven ground. Furthermore, the intuitive control panel, along with optional features including a wireless remote control, a load moment indicator, and a hydraulic flying jib, significantly expands the working envelope behind obstacles while providing operators with a safe control distance, reducing fatigue and improving overall lifting efficiency in confined spaces.
Crawler Spider Crane
A crawler spider crane is a lifting device featuring a crawler travel mechanism, named for its resemblance to a spider in appearance.
Key Features and Advantages:
Excellent Stability: Constructed from high-quality steel, it offers high load capacity and superior anti-slip performance, making it suitable for various complex terrains and environments.
Strong Adaptability: It performs reliably on challenging surfaces such as swamps, riverbanks, deserts, paddy fields, tropical rainforests, snowfields, and icy terrain, ensuring stable mobility across diverse ground conditions.
User-Friendly Operation: Designed for labor-saving control and easy automation, it is equipped with an electric start system and hydraulic cooling system to significantly enhance operational efficiency.
Versatile Functionality: Capable of steering, slewing, telescoping, hoisting, and luffing. The boom can be adjusted flexibly to meet specific construction requirements.
Applications:
Power Construction: In power grid construction sites, the crawler spider crane enables precise hoisting while maintaining safe clearance distances from live electrical components as required by regulations.
Building and Civil Engineering: Ideal for steel structure installation in buildings and roofing projects, as well as civil construction projects including airports, railway stations, and dam construction sites.
Confined Space Operations: Particularly well-suited for working in narrow spaces, such as indoor glass installation, curtain wall installation, and rooftop operations.
Emergency Rescue: Applicable to disaster relief efforts, capable of operating stably in complex terrains and harsh environments.
Industrial and Automotive Manufacturing: Used for equipment maintenance, line replacement, and material lifting in factories and automotive workshops—especially in areas where bridge cranes lack sufficient working space.
Application scenarios
Power Grid & Utility Construction : Enables precise lifting operations on power grid sites while strictly maintaining specified safety distances from live electrical components.
Building & Municipal Infrastructure : Ideal for structural steel installation inside buildings and roofs, as well as municipal construction projects including airports, railway stations, and dams.
Confined & Narrow Space Operations : Engineered specifically for tight areas such as indoor glass lifting, curtain wall installation, and rooftop maintenance.
Emergency Rescue & Disaster Relief : Operates reliably across rugged terrains and hostile environments during emergency disaster relief and recovery missions.
Industrial Plants & Manufacturing Workshops : Designed for equipment maintenance, line replacement, and material hoisting in manufacturing facilities, particularly where overhead bridge cranes lack clearance.
