Processor is closed electronic switch, motor rotation, and motor drives bobbin winder bracket backrush, then hoist cable is retracted, because hoist cable hangs,
During withdrawal hoist cable rise, then the hoist cable near waist joint device will rise when scraping collision to install cantilever arm
On spring, spring scraped upwards, then spring has touched contact, and remote controler will be to motor control after receiving the signal of contact
Device processed sends stalling order, then motor stalls, after rundown time reaches the stalling interval time of time relay setting, then electric
Machine rotates again under the control of electric machine controller, stalls until hoist cable scraping collision to spring, and such design is so that operation people
Member in climbing, also shrink hoist cable therewith, and hoist cable contraction can automatically control, and touching spring can stop, not by timing
Very big pulling force can be applied to operating personnel to drag down operating personnel, it is highly-safe, it, then can be by when under operation human error pendant
Hoist cable is hung, will not fall on the ground, motor have band-type brake, motor stall when be it is locked, ensure that bobbin winder bracket will not be in operation
Member's gravity extension volume, after operating personnel's climbing is to the position more slightly higher than device footstock, then hoist cable can touch footstock and stretch
The spring on arm and keep touching state out, in this way in the state of, motor not can rotate, and hoist cable will not be shunk, and operator can
Trust climbing.
