Operational principle 

The operational principle of the telescopic knuckle boom crane revolves around the synergetic interplay of its key components: the boom, hoisting mechanism, slewing unit, and electrical system. The boom, capable of telescoping and folding as dictated by job requirements, adapts seamlessly to diverse operational environments and spatial constraints. The hoisting mechanism, utilizing load-bearing elements such as steel wire ropes, efficiently handles the lifting, loading, unloading, and transportation of objects. The slewing unit endows the crane with 360-degree rotation capability, enabling precise adjustment of the lifted object's direction and position. Lastly, the electrical system serves as the central control hub, orchestrating all movements and operations of the crane to ensure precision and safety throughout the work process.
