Product Description
The 4-ton crawler spider crane is a highly compact mini mobile lifting machine engineered for tight spaces and complex high-altitude environments. Powered by a robust Changchai three-cylinder 14.7 kW engine with a dual diesel/electric power system, combined with a 2.8 m × 7-section high-strength manganese steel telescopic boom, it delivers superior lifting performance with a maximum lifting height of 15 m and a maximum operating radius of 13 m at a lightweight self-weight of just 3 t, achieving precise inching control and optimal operational efficiency. With an overall width of only 1 m, its non-marking rubber tracked chassis enables it to easily enter narrow or indoor access routes inaccessible to traditional large cranes.
This equipment is widely applicable to high-rise rooftop lifting, power station maintenance, municipal engineering, and equipment maintenance inside large factories, allowing flexible access to complex job sites and safe operation near obstacles. Its 3-stage telescopic outrigger system—featuring manual extension and automatic hydraulic support—ensures exceptional stability and rapid leveling on various terrains. Furthermore, the user-friendly control panel—along with optional features such as a wireless remote control, a load moment indicator, and a hydraulic flying jib—provides an open field of view and a safe operating distance, significantly boosting site productivity while ensuring maximum operational safety.
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.
