摘要： A safety device for a hydraulic elevator includes an open-door running prevention unit and a pressure sensor. The open-door running prevention unit includes a memory configured to sequentially store values of the pressure sensor during a period in which the hydraulic elevator is in the open-door state as time-series data. When it is determined that the car speed, detected when the hydraulic elevator is in the open-door state, is equal to or larger than a preset first threshold value, the open-door running prevention unit calculates a differential value between a maximum value and a minimum value of the time-series data stored in the memory in a period of a preset determination time. When the differential value is out of a preset allowable range, the open-door running prevention unit determines that the open-door running abnormality is present, and executes the car braking processing.

摘要： Process and apparatus for controlling a hydraulic lift wherein with this process, a direct approach to a floor can be achieved without requiring a creeping velocity drive, whereby the car is controlled in a position-dependent manner during the deceleration phase, for the purpose of which a control region is formed which is subdivided into percentage values, the percentage values being retained in tabular form with reference to measured actual position values and upon input of a specific actual position value, the corresponding percentage value is multiplied with the value of the control region (CS) and to this product eventually are added a control deviation (CO) and a pilot control signal (SO) wherein the sum which constitutes the actual control signal used during the deceleration phase, is forwarded to a regulation valve arrangement. An apparatus for carrying out the process is also set forth.

摘要： A control system for controlling the motion of a hydraulic elevator calculates a deceleration distance based upon the elevator velocity and begins the deceleration phase of the elevator motion upon the elevator reaching the calculated distance from the landing. In a particular embodiment, the control system includes a hydraulic valve, a space encoder, and a controller. The space encoder produces velocity and position measurements. The controller uses the velocity inputs to determine the deceleration distance and, upon the elevator car 14 reaching the calculated distance from the landing as measured by the position inputs from the space encoder, commands the hydraulic valve to actuate and begin the deceleration phase. In an alternate embodiment, an interface unit connected between the controller and the hydraulic valve calculates a delay between the deceleration command based upon a predetermined distance and the calculated deceleration distance based upon car velocity. Upon expiration of the delay, the interface unit commands the hydraulic valve to actuate and begins the deceleration phase.

摘要： A drive system for an hydraulic elevator operated at a constant output power for any load during elevator car travel in the upward direction. The maximum nominal speed in the upward direction is selected for a load which typically occurs most frequently and the drive is designed accordingly. The car speed is reduced correspondingly for higher loads and increased correspondingly for lower loads. The variable car speed is achieved either through the use of an adjustable pump of variable displacement volume controlled by a pressure regulating valve or through the use of a positive displacement pump of constant displacement volume which is driven by a frequency regulated electrical motor.

摘要： Control valve for a hydraulic elevator provided with a speed regulating plug which moves in response to the flow of the hydraulic fluid and whose position determines the flow of hydraulic fluid into the actuating cylinder of the elevator. At each end of the speed regulating plug, there is connected a system of hydraulic channels in which the hydraulic fluid flows, and which communicates with the main hydraulic circuit. An additional channel is connected to the hydraulic channel system, the additional channel being provided with a flow resistance component comprising a capillary throttle and a pressure compensated reservoir, such that the flow of hydraulic fluid through the additional channel is varied in inverse relation to the viscosity of the fluid. By this means, the closing speed of the speed regulating plug, and thus the deceleration rate of the elevator, is maintained constant throughout the operating temperature range of the hydraulic fluid.
