Common features of elevators

Control systems of elevators in general (safety devices B66B 5/00; controlling door or gate operation B66B 13/00; systems of general application G05)

Control systems without regulation, i.e. without retroactive action

hydraulic

electric

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

specially adapted for mining hoists

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

with devices, e.g. push-buttons, for indirect control of movements

with means for storing pulses controlling the movements of a single car or cage

with means for storing pulses controlling the movements of several cars or cages

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

with means for taking account of delayed calls

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

mechanical
