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.

Low Ground Pressure & Floor Protection

Rubber-tracked or wheeled bases distribute weight evenly, preventing damage to delicate floors (e.g., marble, wooden decks). Suitable for historic buildings or high-end commercial spaces.

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

How do spider cranes ensure stability on uneven terrain?

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.
Yes, spider cranes are relatively easy to transport. Their compact size and the ability to retract the legs and arm into a smaller form factor reduce their overall dimensions. Many spider cranes can be disassembled into smaller components for transportation and then quickly reassembled on - site. They can be loaded onto trucks or trailers, making them convenient for moving between different job sites.
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.
