Systems, apparatuses, and methods are described for a vertical platform lift assembly control system are disclosed. The control system may provide a method for monitoring sensors for the vertical platform lift, and may determine operating modes and fault conditions from the sensor data. An indicator system for the vertical platform lift may provide user feedback based on sensor data and the status of the control system.

An elevator system is provided that includes an elevator car, a counterweight, a load bearing flexible member, a motor having a drive, and an elevator control system. The car and counterweight are operable to be translated within a hoistway. The load bearing flexible member extends between the elevator car and the counterweight. The motor is operable to move the load bearing member and thereby drive the elevator car and counterweight within the hoistway. The elevator motor and drive are configured to selectively produce regenerative power. The elevator control system includes a power manager unit and a power storage device. The power storage device includes a supercapacitor unit and a battery unit. The power manager unit is operable to selectively manage the flow of power between the power storage device and the motor drive, and the flow of regenerative power from the motor drive to the power storage device.

Elevator access systems are provided. The elevator access systems include a bushing having a keyway, a plunger disposed within the bushing and movable relative thereto, a lever operably connected to the plunger, and a removable plug located within the keyway of the bushing, wherein the removable plug urges the plunger and the lever into a first position, and upon removal of the removable plug, the plunger and the lever move to a second position, wherein in the second position the plunger is accessible to operate the lever.

An elevator rescue system allows an elevator car of an elevator to be moved in an emergency situation. The elevator includes an elevator motor acting on hoisting ropes by which the elevator car is suspended including at least one electro-mechanical brake and an encoder outputting a signal corresponding to its speed. The rescue system includes a back-up power source, a jerk monitoring circuit connected to the encoder and including a memory storing an upper threshold value for the derivative of car acceleration, a brake feed circuit controlled by the jerk monitoring circuit, and a release switch connected to the jerk monitoring circuit and/or to the brake feed circuit. The release switch activates the brake feed circuit to release the brake, and initiate the jerk monitoring circuit to compare the derivative of car acceleration derived from the encoder signal with the stored first upper threshold value, and forwards a control signal to the brake feed circuit to initiate/stop braking depending on the comparison result.

An elevator system includes a primary source of electrical power; a power unit having a power supply, the power supply producing DC power from the primary source of electrical power. A rescue storage device provides power to the elevator system when the primary source of electrical power is unavailable. The rescue storage device is coupled to an output of the power supply to provide additional DC power with the DC power when the primary source of electrical power is available and an increased power requirement is present.
