A pressurized fluid powered cabin-management system for an elevator system with a cabin and drive system is provided. The cabin-management system is configured to direct operation of the elevator system upon arrival of one of the cabins at a floor, and comprises a floor detector configured to detect when the cabin is located at a floor and to activate a timer. The timer is configured, when triggered, to activate a timing arrangement and to pass pressurized fluid to a control valve being in a first position. The timing arrangement is configured to direct the control valve to assume a second position after a predetermined amount of time. The cabin-management system performs, when pressurized fluid is passed to the control valve in its first position, actions for opening a door, and, after the control valve has assumed its second position, actions for travel of the cabin.

A locking device for a guide rail is disclosed. The device includes a first edge including a plurality of teeth shaped projections. The first edge compresses and locks a first surface of a covering sheet placed on a base ring. The device also includes a second edge opposing the first edge. The second edge includes a V-shaped groove, wherein the second edge is disposed to hold at least one furrow of the guide rail for interlocking. The first edge and the second edge of the locking device locks air gap between the covering sheet, the guide rail connecting one or more surfaces of the base ring and a vertical pillar coupled to the guide rail.

A landing lever assembly of a pneumatic vacuum elevator is disclosed. The assembly includes a landing lever plate coupled on a roof of an elevator cabin. The assembly also includes a locking plate coupled to the landing lever plate using a plurality of support plates. The assembly further includes a solenoid valve disposed on the landing lever plate and mechanically coupled to the locking plate using a guide pin, where the guide pin is configured to actuate the locking plate by sliding within the solenoid valve, in at least one operational mode, based on an activation signal received from a magnetic sensor.

An overload valve assembly for a pneumatic vacuum elevator is disclosed, The overload valve assembly for a pneumatic vacuum elevator is characterised by a fastening means, a pad with a centre hole, an arresting plate with a centre hole, a disc plate with a centre hole, a bottom bush, a spring and a top bush bounded with a nut. Here, the pad, the arresting plate, the disc plate, the bottom bush, the spring and the top bush bounded with the nut is fitted over the fastening means. The overload valve unit is configured to function based on spring actuation mechanism and ensure the maximum permissible limit of pay load in the elevator cabin assembly.

A pneumatic flow controlling device is disclosed. The device includes a perforated component disposed on a bottom component coupled to a top surface of a pneumatic vacuum elevator. The perforated component includes multiple perforations to enable air circulation from outside to inside of the elevator cylinder. The device also includes a diaphragm component to expand and compress based on the air circulation. The device also includes a primary valve to allow an air supply to the elevator cylinder for controlling movement of an elevator cabin within a tubular pathway based on a control signal received from an elevator controller. The device also includes a secondary valve to allow the air supply to the elevator cylinder for dynamically varying speed of the elevator cabin at one or more landing positions.
