Breakthrough in large-tonnage spider cranes breaks the operational boundaries of mini lifting equipment.

Traditional spider cranes, limited by their size and structural design, typically have lifting capacities below 5 tons, failing to meet the lifting needs of heavy components in confined spaces. To overcome this limitation, industry players have increased investment in technological research and development, launching several large-tonnage spider crane models. By optimizing hydraulic systems, upgrading outrigger structures, and using high-strength materials, lifting capacities have been increased to over 10 tons, while maintaining a compact design and foldable outriggers, enabling the lifting of heavy equipment and large components in confined spaces.

The new large-tonnage spider cranes employ a dual-pump confluence hydraulic system, improving the power and efficiency of lifting operations. They are also equipped with an advanced torque limiting system that calculates the safe operating range in real time based on the working radius, lifting weight, and outrigger deployment status. If the safety boundary is exceeded, a protection mechanism is immediately triggered to stop the dangerous operation. In industrial plant renovation projects, large-tonnage spider cranes can enter workshops to lift and move heavy machine tools and boiler equipment without demolishing factory walls or building large lifting platforms. In port logistics, these machines can lift large container components and heavy cargo in narrow passageways of container yards, solving the problem of large cranes being unable to access the area. Furthermore, large-tonnage spider cranes are equipped with wireless remote control and visual monitoring systems, allowing operators to view the status of the load and the surrounding environment in real time via cameras, improving the accuracy and safety of lifting operations. The introduction of large-tonnage models has completely broken down the operational boundaries of spider cranes, further expanding their application scenarios.
