The use of a picture stick [free device] for quick chain pulling has high work efficiency, stable braking, and high safety.
The long shaft adopts a patented structure, with multiple limit control for higher braking effect and more reliability.
The handwheel is connected with involute splines, making the long shaft and handwheel a whole and less susceptible to external interference.
The optional gear tooth ratio is used, and the operating force of the handle is very small.
The standard configuration is high-strength alloy steel lifting chain
Forged hook with specialized heat treatment, high strength and long service life
