Description
The 8 ton spider crane is a heavy-capacity mini crawler crane engineered specifically for industrial lifting in confined workshops, factories, and restricted job sites. Its compact body and foldable hydraulic outriggers allow the crane to pass through narrow entrances and deploy safely in tight production areas where conventional truck cranes cannot operate.
Powered by a 380V electric system, the crane delivers low-noise, zero-emission performance, making it ideal for indoor environments such as manufacturing plants, assembly lines, and equipment rooms. The five-section U-shaped telescopic boom provides superior structural strength and stability, enabling safe handling of heavy molds, machinery, and industrial components.
The crane features an advanced boom and outrigger interlock safety system, ensuring safe sequencing during operation and travel. Its crawler undercarriage provides stable positioning and smooth maneuverability across factory floors and uneven industrial surfaces.
