QBD construction elevator has reliable electric system,mechanical chain safety device,designed with safety switch,upper and lower limit switches,security hook,etc.Main advantages:mast using bending steel band,top class rack,big-power anti-fall safety device,24V low-voltages control,more than seven positions with galvanized process,test in workshop before delivery.

Frequency construction hoist(optional)has the following features:

1.smooth start without bumps

2.speed can be adjusted by the operator

3.starting current smaller than the rated current

4.with the smooth start,abrasion can be largely reduced on the rack and gear,and brake abrasion also can be reduced obviously

5.obvious energy saving

Computer-control automatic leveling system,calling device 9 optional has the following features:

1.simple strucure,controller using SCM;signal input by photocell

2.stop using decreased recovery,cage weights overcomes the inertia to make the max deviation smaller than 3mm

3.with the function prevent the illegal operation

4.strong anti-interference performance

5.electronic calling devices help the cage stop at the required foor with improved efficiency
