Spider cranes are lightweight lifting equipment suitable for operations in confined spaces, indoor environments, and complex terrains. They are widely used in substation renovations, glass curtain wall installations, steel structure factories, subway construction, equipment maintenance, and other scenarios. The equipment employs a tracked walking mechanism, coupled with a foldable boom and wireless remote control system, enabling it to rotate in place, navigate narrow alleys, and operate on floors. The machine features high lifting capacity, a small footprint, and convenient transportation. Optional configurations include extended outriggers, a secondary boom, and adjustable winch speeds to meet diverse working conditions.
