A modular cabin assembly 100 for an elevator 200 is provided. The assembly includes a housing 102 which includes a roof assembly 104, and a floor assembly 118. The roof assembly includes a plurality of first connectors 106 connected with a plurality of perforated brackets 108 and coupled with a plurality of vertical posts 110 and is coupled with each other by means of a plurality of joints 114. Each of the plurality of joints includes a projection 116 at the top face of each joint. The floor assembly includes a plurality of protruding portions 120, and a covering structure 122. A first pillar 128a, a second pillar 128b, and a fourth pillar 128d of at least four pillars 128 coupled with the roof assembly and the floor assembly. A third pillar 128c at least four pillars comprise a second vertical post guide rail, coupled with the roof assembly.

A suspension arrangement 10 to absorb stress acting on an elevator cabin 20 during landing is provided. The suspension arrangement includes the elevator cabin to move bidirectionally through an external cylinder 30 to transport passengers between levels of a structure. The suspension arrangement includes a landing lever 40 to project towards the external cylinder when the elevator cabin reaches a floor level. The suspension arrangement includes a landing bar 50 to slide downwards over the pillar 60 corresponding to a motion of the landing lever upon establishing a contact with the landing lever projected towards the external cylinder. The suspension arrangement includes a guide pin 70 meshed with the landing bar and housed in a base ring 80 associated with the external cylinder. The guide pin is to compress a spring 90 encircling the guide pin corresponding to the motion of the landing bar.

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.

A hydraulic elevator system includes a power unit and elevator controller where the elevator car is controlled within the hoistway when a portion of the hoistway might be flooded. The power unit includes a water tight tank having a ventilation tube or snorkel. A moisture sensor is connected with the elevator controller, and positioned within the pit of the hoistway. The moisture sensor detects the existence of a flooded pit condition and communicates such a condition to the elevator controller. The elevator controller initiates a safety sequence when the presence of a flooded pit condition is detected to prevent the elevator car from entering a flooded area of the hoistway.

A Split Vacuum Elevator System has a channel connecting a vacuum elevator cylinder or thoroughfare to an electric equipment housing having motors and valves for the operation thereof. The channel is attached at a top of the elevator thoroughfare through a raised protrusion (or more raised protrusions if there are more then one channel) in a sealing plate that is itself attached to the support structure of the thoroughfare. The other side of the channel is connected to an air buffer known as a collector. This collector has one or more protrusions to connect to one or more channels. A raised lip on the collector facilitates the attachment of the housing thereto.
