1. A suspension arrangement (10) to absorb stress acting on an elevator cabin (20) during landing, wherein the suspension arrangement (10) comprises:
the elevator cabin (20) positioned in an external cylinder (30) of a pneumatic vacuum elevator, wherein the elevator cabin (20) is adapted to move bidirectionally through the external cylinder (30) to transport one or more passengers between one or more levels of a structure;
a landing lever (40) mechanically coupled to a top portion of the elevator cabin (20), wherein the landing lever (40) is adapted to project towards the external cylinder (30) when the elevator cabin (20) reaches a floor level preferred by the one or more passengers, wherein the landing lever (40) is adapted to retract towards the elevator cabin (20) upon establishing the contact with a projection (100) associated with the external cylinder (30);
a landing bar (50) operatively coupled to the landing lever (40) and mounted on a pillar (60) of the external cylinder (30), wherein the landing bar (50) is adapted to slide downwards over the pillar (60) corresponding to a motion of the landing lever (40) upon establishing a contact with the landing lever (40) projected towards the external cylinder (30), wherein the landing bar (50) comprises a counter boring (120) adapted to accommodate the guide pin (70) and a nut (130) fastened to the guide pin (70);
a guide pin (70) meshed with the landing bar (50) and housed in a base ring (80) associated with the external cylinder (30), wherein the guide pin (70) is adapted to compress a spring (90) encircling the guide pin (70) corresponding to the motion of the landing bar (50), thereby absorbing the stress acting on the elevator cabin (20) during the landing; and
a grub screw (110) adapted to restrict an upward movement of the landing bar (50) over the pillar (60).
