Description
The SANSCM ST-500 5 ton spider crane is a heavy-duty mini crawler crane designed to deliver powerful lifting performance in areas where traditional cranes cannot access. Its compact structure and crawler chassis allow easy movement through narrow entrances, industrial facilities, and urban construction sites, making it an ideal solution for contractors, equipment installers, and lifting service providers.
The crane is equipped with a high-strength telescopic boom and hydraulic lifting system, providing excellent stability and precise load control when handling heavy glass panels, steel structures, and industrial machinery. The multi-position hydraulic outriggers enable secure setup on uneven ground, confined spaces, and complex jobsite environments.
With its extended lifting height and working radius, the crane allows operators to complete lifting tasks efficiently without frequent repositioning, improving productivity and reducing downtime. The heavy-duty crawler undercarriage ensures smooth travel and strong traction, allowing reliable operation on rough terrain, slopes, and construction surfaces.
