Spider cranes are mainly used in construction, interior decoration, remodeling, maintenance of equipment in workshops, electrical repair and jungle work.
Product features: Mainly small size, suitable for narrow or restricted space operation, with flexible operation, widely used.
Solutions for spider cranes, for example, are as follows:
Building construction enterprises: for curtain wall installation in high-rise buildings, steel structure lifting and loading, and narrow space operation (e.g., indoor decoration, roof construction)

Wind power installation companies: for lifting and loading of wind turbine equipments in complicated terrains (e.g., mountainous areas, offshore).
Logistics and warehousing companies: for heavy cargo loading and unloading and precise handling in warehousing spaces.
Factories and workshops: for production line equipment maintenance, lifting of heavy parts in workshops.
Municipal engineering units: for bridge maintenance, underground pipe installation and other scenarios that require flexible mobility.
