Further characteristic: an end of said anti-fall gangbar is to be connected on the anti-fall eccentric wheel through pin.
Two ends at transverse axis all are provided with preloading spring.
The anti-fall eccentric mobile device of the utility model integral lifting scaffold with respect to prior art, has following characteristics:
1, the structure that adopts eccentric wheel to cooperate with vertical main frame, in the main frame Shi Gengneng increase clamping force of down falling, clamping tightlier stops falling main frame, plays extraordinary security protection effect.
2, scaffold can make things convenient for, reliably the eccentric wheel backward rotation unclamped main frame when descending, and main frame can descend under slave mode.
3, the elastic force of two preloading springs about, through transverse axis with about two anti-fall gangbar act on the anti-fall eccentric wheel, make anti-fall eccentric wheel and vertical main frame keep excellent contact, also can improve safety.
4, can adapt to high level, construction of super highrise building needs.
