Description
The ST-300 3 Ton Spider Crane is a compact mini crawler crane engineered for precision lifting in confined spaces where conventional cranes cannot operate. Designed for construction contractors, glass installation companies, industrial maintenance providers, and equipment installers, it provides reliable lifting performance while maintaining exceptional maneuverability.
Its ultra-compact crawler chassis allows the crane to travel through narrow access points such as standard doors, elevators, and interior corridors, making it ideal for indoor lifting, factory installation, and urban construction projects. The hydraulic multi-position outriggers with interlock protection ensure maximum stability on uneven ground, stairs, or restricted work zones.
The crane features a heavy-duty hydraulic winch with multi-line wire rope, delivering smooth and controlled lifting with a maximum capacity of 3 tons and lifting height up to 11.5 meters. The proportional remote control system allows operators to perform precise positioning safely, especially in glass curtain wall installation, steel structure assembly, and equipment placement.
With non-marking rubber tracks, strong climbing ability, and fast deployment capability, the ST-800 improves lifting efficiency while reducing labor costs and dependence on large cranes.
