Synopsis
Nibav Lifts USA offers innovative home elevators requiring no pit, shaft, or machine room. Ideal for compact spaces, they provide effortless installation, smooth rides, and safety for every home. Upgrade your living with Nibav’s smart, space-saving solutions.
What it is
The no-pit, no-shaft, no-machine-room home elevator is a type of residential elevator that does not require any structural excavation, a dedicated elevator shaft, or an independent equipment room to operate. Conventional residential elevators must have a concrete pit beneath the lowest floor, a vertical shaft to guide the cabin, and a machine room to accommodate motors, pumps, and controllers. By avoiding these components of a conventional elevator system, construction costs, spatial requirements, and installation complexity can be greatly reduced.
Nibav USA home elevators eliminate all three through a self-supporting pneumatic vacuum structure. The elevator travels inside a cylindrical tube that acts as both the guide path and the structural frame. All drive components, air turbines, controls, and safety systems are built into this vertical tube itself. The elevator rests directly on the finished floor and only requires simple floor cutouts between levels for travel. This design allows a complete residential elevator to be installed inside living spaces such as stair voids, corners, or open areas without changing the building’s structure.
Why it matters
In most American homes, especially those built with wood framing, post-tension slabs, or crawl spaces, constructing a pit, shaft, and machine room is either extremely expensive or structurally risky. Excavation can interfere with foundations, plumbing, or electrical lines, while shaft construction requires removing floors, beams, and walls. Using a system that does not require a pit, shaft, or machine room indicates that you are being provided with a no-dig system that will alleviate:
- No excavation/concrete work
- No structural reinforcement
- Preserved living space
- Decreased installation time
- Decreased cost of total project
By using an elevator system designed for residential applications, Nibav elevators are capable of supporting their own loads. As a result, these systems are perfect for retrofitting into existing homes without affecting daily life routines.
Who needs this?
Home elevators with no pit, shaft, or machine room are ideal for:
1. Existing homes
They can be installed without structural demolition.
2. Wood-frame and slab-on-grade homes
No excavation or reinforcement is required.
3. Homes with limited space
The elevator occupies only its cylindrical footprint.
4. Seniors planning to age in place
Accessibility can be added later without renovation.
5. Luxury and modern homes
The transparent tube becomes a design feature.
Technical details
Nibav USA achieves this design through a combination of self-supporting construction and pneumatic vacuum technology.
1. Self-supporting structure
The elevator uses a reinforced cylindrical aluminum and steel frame that carries:
- Cabin weight
- Passenger load
- Vertical travel forces
All loads are transferred directly into the base ring on the floor.
2. No pit installation
The cabin rests on the finished floor surface. There are no components below floor level.
3. No shaft requirement
The transparent vertical tube acts as the guide and enclosure, eliminating the need for masonry or steel shafts.
4. No machine room
All turbines, control boards, and safety devices are housed within the top section of the tube.
5. Pneumatic drive
Air pressure differences lift and lower the cabin, removing the need for motors, cables, or hydraulic pistons.
Common questions
1. Does it really need no pit or shaft?
Yes. The entire system is self-contained.
2. Is it safe without structural support?
Yes. The frame carries all operational loads.
3. Can it be added to an existing home?
Yes. It is designed specifically for retrofits.
4. Does it affect the foundation?
No. It rests on the finished floor.
5. Is this standard for Nibav USA elevators?
Yes. This is a core design of Nibav’s pneumatic systems.
