Advantages

Compact Size & Maneuverability in Tight Spaces

Ultra-small footprint (e.g., 1.5m width) and retractable legs enable access to elevators, doorways, or narrow alleys. Ideal for indoor renovations, museum installations, or aircraft maintenance.

Multi-Directional Movement

360° rotating boom and articulating jib allow precise positioning in complex layouts. Can lift loads around obstacles or into hard-to-reach areas, reducing the need for manual repositioning.

High Lifting Capacity for Its Size

Despite compact dimensions, some models lift up to 10 tons, making them ideal for small-scale heavy lifting in urban construction or industrial maintenance.

Frequently Asked Questions

What makes spider cranes suitable for indoor use?

Spider cranes' compact size and multiple retractable legs allow them to navigate through narrow doorways and operate in confined indoor spaces. Their low profile enables them to work under low ceilings. The ability to adjust leg positions provides stability on uneven indoor floors, and their precise control systems ensure safe and accurate lifting operations without causing damage to the interior environment.
Spider cranes have multiple independently adjustable legs. These legs can be extended or retracted to different lengths, allowing the crane to balance itself on uneven surfaces. The outrigger system distributes the crane's weight and the load's weight evenly, increasing stability. Additionally, sensors and control systems monitor the crane's balance in real - time and make adjustments to prevent tipping.
The lifting capacity of spider cranes typically ranges from a few hundred kilograms to around 10 tons. Smaller models, often used for indoor tasks or light construction work, may have a capacity of 1 - 3 tons. Larger, more heavy - duty spider cranes designed for outdoor construction and industrial applications can handle loads up to 10 tons or more, depending on the specific model and configuration.
Regularly inspect the hydraulic system for leaks, and check the hydraulic fluid level and quality. Lubricate moving parts, such as joints and pivots, to reduce wear. Inspect the legs, outriggers, and arm for any signs of damage or deformation. Check the electrical and control systems for proper operation. Periodically test the safety devices, such as limit switches and overload protection, to ensure they are functioning correctly.
