Common features of elevators
 

 1
/ 00 Control systems of elevators in general (safety devices B 66 B 5/00; controlling door or gate operation B 66 B 13/00; systems of general application G 05)

1
/ 02 • Control systems without regulation, i.e. without retroactive action  

1
/ 04 • • hydraulic  

1
/ 06 • • electric  

1
/ 08 • • • with devices, e.g. handles or levers, in the cars or cages for direct control of movements  

1
/ 10 • • • • specially adapted for mining hoists  

1
/ 12 • • • with devices, e.g. handles or levers, located at a control station for direct control of movements, e.g. electric mining-hoist control systems  

1
/ 14 • • • with devices, e.g. push-buttons, for indirect control of movements  

1
/ 16 • • • • with means for storing pulses controlling the movements of a single car or cage  

1
/ 18 • • • • with means for storing pulses controlling the movements of several cars or cages  

1
/ 20 • • • • • and for varying the manner of operation to suit particular traffic conditions, e.g. "one-way rush-hour traffic"  

1
/ 22 • • • • with means for taking account of delayed calls  

1
/ 24 • Control systems with regulation, i.e. with retroactive action, for influencing travelling speed, acceleration, or deceleration  

1
/ 26 • • mechanical  

1
/ 28 • • electrical (detecting excessive speed B 66 B 5/04)  

1
/ 30 • • • effective on driving gear  

1
/ 32 • • • effective on braking devices  

1
/ 34 • Details  

1
/ 36 • • Means for stopping the cars, cages, or skips at predetermined levels  

1
/ 38 • • • and for returning the controlling handle or lever to its neutral position  

1
/ 40 • • • and for correct levelling at landings  

1
/ 42 • • • • separate from the main drive  

1
/ 44 • • • and for taking account of disturbance factors, e.g. variation of load weight  

1
/ 46 • • Adaptations of switches or switchgear (switches or switchgear in general, applications of switches or switchgear for floor-levelling purpose H 01 H; panels for boards or switching arrangements H 02 B 1/015)  

1
/ 48 • • • Adaptations of mechanically-operated limit switches (for cranes B 66 C 13/50; for winding mechanisms B 66 D 1/56 )  

1
/ 50 • • • with operating or control mechanisms mounted in the car or cage or in the lift well or hoistway  

1
/ 52 • • • Floor selectors
