Spider Crane
3 tons spider crane
A "spider crane" is a compact hydraulic crane specifically designed for narrow or complex spaces. It gets its name from the way its four hydraulic outriggers resemble the legs of a spider when extended. Its primary advantage is the ability to access areas where conventional, large-scale cranes cannot fit, while still performing lifting operations with stability.

Characteristic

  • Independent multi-leg supports

    The four outriggers can be extended and retracted independently for leveling; this allows for flexible adjustment of the support span to accommodate uneven ground or irregular site conditions, eliminating the need for extensive site leveling.

  • Flexible boom, capable of clearing obstacles, 360° full rotation

    The entire unit supports continuous 360° rotation and features hydraulic proportional control, offering excellent inching capabilities and precise load positioning. It is ideal for the delicate placement of precision equipment or fragile glass, with smooth, cushioned starts and stops that minimize swaying.

  • Compact body

    Once retracted, the unit is extremely compact; its narrow profile allows it to pass through standard doorways, elevators, and corridors to reach interiors, basements, mezzanine levels in factories, or rooftops—accessing spaces that are completely inaccessible to larger machinery.

  • Flexible power solutions

    Mainstream models feature a dual-power (diesel-electric) system: they utilize an electric motor for indoor operation—ensuring low noise, zero exhaust emissions, and environmental friendliness—while relying on diesel power for outdoor use, free from the constraints of a power supply. A fully electric version is also available.

  • Low relocation costs; one machine, multiple uses

    Compatible with a wide range of attachments—such as vacuum glass lifters, man baskets, and grapples—this equipment handles both lifting tasks and aerial work. A single unit covers diverse operational scenarios, offering a more cost-effective solution for rental or purchase, with the added benefit of simple maintenance.
