The main boom main chord adopts high-strength thin-arm steel pipe, which is light in weight and greatly improves the lifting performance.
Complete safety devices, more compact and compact structure, suitable for complex construction environment.
The unique gravity lowering function can save fuel consumption and improves work efficiency.
With rotary floating function, it can achieve high-altitude accurate positioning, and the operation is more stable and safe.
The fragile and consumable structural parts of the whole machine are self-made parts, which are unique structural design, convenient maintenance and low cost.
