1. A landing lever assembly of a pneumatic vacuum elevator comprising:
a landing lever plate coupled on a roof of an elevator cabin;
a locking plate coupled to the landing lever plate using a plurality of support plates; and
a solenoid valve disposed on the landing lever plate and mechanically coupled to the locking plate using a guide pin,
wherein the guide pin is configured to actuate the locking plate in at least one operational mode, wherein the at least one operational mode comprises:
actuating the locking plate in a forward direction by sliding the guide pin in the forward direction based on an activation signal received from a magnetic sensor; and
actuating the locking plate in a backward direction by sliding the guide pin in the backward direction based on an activation signal received from a magnetic sensor.
