Tower Crane YFB-1
Tower crane adopts step-less speed regulation of frequency conversion,with the characteristics of extremely stable braking effect and quick andaccurate emplacement. Using mechanical-electrical integration design, CAD-aideddesign, optimization design, modular design and other advanced design means,tower crane's steel structure has excellent strength, stiffness and fatigue anddestructive resistance capacity. Its pretty outline reflects our high designstandards.
