Spider cranes are compact, maneuverable lifting equipment, also called spider crawler cranes. They overcome the limitations of traditional bulky cranes, with a stable crawler structure, telescopic boom, and 360° rotation, delivering reliable lifting in narrow spaces inaccessible to standard equipment. The 3-ton spider crane, a representative lightweight, high-adaptability model in this category and also known as a small spider crane, is engineered for precision lifting operations in extremely limited spaces. It replaces oversized lifting equipment, balancing robust lifting capacity with an ultra-compact footprint, making it the ideal solution for indoor construction, narrow-space maintenance, and other lifting tasks that demand both flexible maneuverability and dependable lifting performance.YG also offers 5 Ton spider cranes.

Small Spider Crane Application :
- Indoor Construction & Confined Space Lifting:Perfect for elevator shafts, basements, mall renovation, and narrow workshop jobs. Its compact size fits standard doorways and elevators, lifting materials and small equipment where large cranes cannot reach.
- Building Facade & Rooftop Maintenance & Renovation:Ideal for glass curtain wall installation, exterior upkeep, old building renovation, and rooftop equipment hoisting. The telescopic boom reaches high places safely, and the crawler base stays stable without damaging the roof’s waterproof layers.
- Municipal Utility & Urban Landscape Works:Suitable for street lamp installation, landscape stone lifting, tree transplanting, and municipal pipe projects. Low-ground-pressure tracks protect roads and lawns, working flexibly in narrow urban streets.
- Industrial Workshop & Warehouse Equipment Installation:Great for the precise installation of machine tools, warehouse racks, and cold storage equipment indoors. It finishes accurate hoisting without damaging existing workshop floors and facilities.
- Power & Telecommunication Remote Site Works:Used for power line parts, base station equipment, and hydropower auxiliary work in mountainous remote areas. Compact and easy to transport, it reaches high working heights on complex terrain.


Advantages of the 3 Ton Spider Crane:
- Ultra-Compact Body for Unmatched Narrow Space Access: The core advantage of this 3-ton spider crane is its ultra-miniature footprint, with a body width of only 980mm and a transport size of 29509801560mm. It can easily pass through standard indoor doorways, enter passenger elevators, and work inside single floors of buildings, a capability completely unavailable for traditional large cranes and even larger spider crane models.
- Lightweight Design with Zero Damage to Delicate Ground Surfaces: With a total weight of only 2700kg and a crawler walking structure that evenly distributes weight, it has an extremely low ground pressure. It will not damage indoor ceramic tiles, epoxy floors, roof waterproof layers, or urban lawns and sidewalks during operation, avoiding high ground repair costs caused by heavy lifting equipment.
- Precise Lifting Performance for Most Daily Lifting Needs: Equipped with a 5-section telescopic boom, it delivers a maximum lifting height of 9.9m and a maximum working radius of 8.83m, with a rated lifting capacity of 3 tons. This performance perfectly covers the vast majority of daily lifting tasks, including small equipment installation, building material hoisting, and municipal maintenance works, avoiding resource waste and high costs from oversized cranes.
- Flexible Maneuverability & Adaptability to Complex Terrain: Driven by a hydraulic motor, it features a crawler walking structure with a 0-2.5km/h walking speed and 25° maximum grade ability. It can move flexibly on uneven ground, gentle slopes, rooftops, and narrow field sites, and supports 360° continuous full rotation to adjust lifting direction in a very small space without moving the whole machine.
- Low Transport & Operating Costs, Easy to Use:Its compact size and light weight allow it to be transported with an ordinary light truck, no heavy flatbed trailer required, greatly cutting transportation costs. It supports both manual operation and optional remote control, with an intuitive operating system. Ordinary workers can master standard operation after short-term training; no professional large crane operator certificate is needed, greatly lowering the use threshold and labor costs.


FAQ About YG 3 Ton Spider Crane:
A: It is equipped with load limit and anti-tipping safety devices. It will automatically stop working once overloaded or in unsafe postures, ensuring stable lifting in confined indoor areas.
A: The textured crawler tracks provide strong friction. It stays stable on wet construction ground, epoxy floors and tiled surfaces without sliding during walking and lifting.
A: Yes, the effective lifting capacity drops as the working radius increases. We provide official load curve charts for each model to guide your safe on-site operation.
A: Auxiliary jib and other practical attachments are optional, which can expand the working height and meet more special lifting scenarios.
A: It adopts an energy-saving power configuration with low hourly fuel consumption, helping you cut long-term operating costs for frequent and long-hour jobs.
A: The compact YG-3 size can be loaded on ordinary light trucks for transportation; no large dedicated transport equipment is required, saving site transfer time and cost.
