The 3-ton Spider Crane is a miniature crawler-type hydraulic crane specifically designed for confined spaces, complex terrain, and precision indoor lifting. Its compact body allows it to easily access environments where traditional large cranes cannot operate, such as elevators and narrow corridors. Equipped with a diesel-electric dual power system, a five-section U-shaped telescopic boom, and a 360° continuous slewing mechanism, it boasts a maximum lifting height of 9.2 meters and a working radius of 8.83 meters. Hydraulic outrigger support ensures stable operation. Optional features include a remote control and a torque limiter.
Combining high load-bearing capacity, high flexibility, and high safety, it is widely applicable to urban construction, indoor installation, curtain wall engineering, airports, and train stations. Professional manufacturers offer readily available stock, customized specifications, and after-sales maintenance services, making it a core piece of equipment for solving lifting challenges in confined spaces.

Product Features Of Crawler Spider Crane
- The 3-ton spider crane boasts a compact size, high lifting capacity, and superior safety rating, making it an unrivaled piece of equipment compared with conventional cranes.
- Initially engineered for more efficient glass installation works, mini crawler spider cranes are also widely applied in indoor spaces, narrow areas, and tight passages.
- Its sleek and compact body design enables the crawler spider crane to operate indoors and in space-constrained areas. The streamlined structure allows for easy access to construction sites and helps reduce operational costs.
- With a small footprint and convenient transport ability, the crawler spider crane is extensively used in curtain wall construction for vertical transportation, hoisting, and other operations. It has a lifting capacity ranging from 3 to 8 tons, which can meet the vast majority of hoisting requirements on construction sites.
- Conventional cranes are unable to access or operate in many locations, such as rooftops, indoor areas, shopping malls, and densely populated zones, while 3-ton spider cranes can perform relevant operations with ease in such places.
- Crawler spider cranes are used for the hoisting of construction materials at airports, railway stations, dam construction sites, and other projects. Thanks to its exceptional flexibility and maneuverability in narrow spaces, this equipment has been widely adopted in numerous municipal construction projects and helps construction workers solve numerous on-site challenges.
