Span winchPublish Date：2012-03-29
The kinematic mechanism of span winch mainly includes mechanism of hoisting, luffing, rotation, and running. The running mechanism is a non-working mechanism.
Key techniques of the span winch electric control system
Multiple main hooks can combinational synchronous as: position synchronizing, speed balance, moment balance, auto flux-weakening
- grab span winch, grab auto switching and deep-excavation control
- hoisting slip proof control
- complete safety protection for electric control system
