Small crawler diesel spider crane excels where traditional machinery cannot reach. Whether you are retrofitting a basement or installing curtain walls, its compact crawler chassis provides the mobility needed for tight job sites. Because it stands only 1.76m high and 0.95m wide, it maneuvers through pedestrian entrances and lifts with total ease.

Diesel-electric spider lift's dual-power versatility is a standout feature: use the zero-emission electric mode to protect indoor air quality, or engage the diesel engine for high-endurance outdoor lifting. To ensure safety on uneven ground, the crane utilizes hydraulic outriggers that extend to nearly 5 meters, providing a rock-solid foundation.

When it comes to reach, the 6-section boom delivers a vertical ceiling of 11 meters. Furthermore, for specialized foundation work, the crane features a dedicated underground wire rope function. This allows for hoisting 0.74-ton loads from depths of up to 40 meters, making it an essential tool for modern urban infrastructure projects.

Solving Job Site Challenges: Navigating Tight Spaces and Ensuring Stability with Mini Spider Cranes

Ultra-Slim 0.95m Chassis: Seamless Access to Confined Environments

Mini crawler spider crane overcomes this with an ultra-narrow footprint, measuring just 3.1m in length and 0.95m in width.

Doorway Compatibility: Designed to traverse standard 900mm doorways and freight elevators with ease.
Surface Protection: Integrated rubber tracks minimize ground pressure, preventing damage to delicate epoxy or tiled flooring.
Precision Handling: Operating at a controlled speed of 2.5 km/h, it provides the agility required for maneuvering within workshops, living rooms, and power stations.

Advanced Stability: Hydraulic Outriggers with a 4.8m Support Span

To mitigate the risk of tipping on soft or irregular terrain, the crane utilizes a manual swing-out outrigger system paired with hydraulic self-leveling.

Once deployed, these outriggers extend to a maximum support base of 4.8m × 3.61m × 4.97m. This wide geometry significantly improves the machine's center of gravity, increasing the critical overturning angle to over 10°. Even with the 6-section boom fully extended to its 10.1m working radius, the structural integrity remains uncompromised, reducing tipping risks by over 50%.

Dual-Power Versatility and High-Reach Capability

Hybrid Drive System: Zero-Emission Indoor & Robust Outdoor Performance

Unlike single-source machinery, this diesel-electric spider crane adapts to any environment. It features a dual-drive mechanism consisting of a 380V electric motor and a reliable Changchai diesel engine.

Indoor Mode: Utilize the electric motor for silent, emission-free operation in sensitive or enclosed areas.
Outdoor Mode: Switch to diesel power for high-endurance work in remote locations. A single 8-liter tank provides enough fuel for a full day of heavy-duty lifting.
