As modern buildings focus more on openness and style, many now use glass elevators. Unlike old closed elevators, these clear lifts not only move people but also make the place look nicer.
As glass elevators become common, many people wonder: What is a glass elevator? How does it work? What kinds are there? What about size, cost, good and bad points, and is it right for a project? This article explores all of these aspects in detail, helping you better understand and evaluate glass elevators for your building.
What is a Glass Elevator?
A glass elevator is a type of lift where at least one side of the shaft or cabin wall is made of transparent glass. This lets passengers see the outside view while moving between floors. Traditional elevators are closed with metal or opaque walls, but glass elevators mix design with function, making the ride part of the experience.
Glass elevator is not only about moving up and down but also about giving an added dimension—sight. Because of this, glass elevators are often chosen for luxury residences, hotels, malls, and towers. They are both a way to travel and a design feature.
Key Features of Glass Elevators
Glass elevators have several important characteristics that make them different from traditional.
- Automatic and safe control: They are operated with advanced systems that keep rides smooth and safe.
- Architectural aesthetics: Transparent walls add style and improve the look of the building.
- Visual openness: Passengers enjoy wide views and feel less confined.
- Compact structure: Supported by steel frames, they use less space.
- Seamless integration: Easy to match with modern architecture and interior design.
- Wide applications: Common in shopping malls, hotels, offices, and upscale homes.
Structure and Working Principle of Glass Elevators
What are the Components of a Glass Elevator?
Glass elevators are made up of different parts that work together as one system. These components are:
- Pit: This is the base of the shaft. It holds the buffer seats, guide rail bases, and drainage system.
- Shaft: Built from a steel frame and transparent panels, it also includes the doors and support equipment.
- Cabin: The car where people ride, made of a cabin frame, glass walls, floor base, ceiling, control panel, and doors.
- Machine room/equipment layer: Houses the traction motor, sheaves, support beams, and the speed governor.
- Other parts: Includes the suspension system, counterweight, safety devices, guide rails, buffers, limit switches, and electrical systems.
How Ddoes a Glass Elevator Work?
A glass elevator usually works with a traction system. This system uses steel ropes that pass over a traction sheave. One end of the rope is fixed to the cabin, and the other is fixed to the counterweight. When the electric motor turns the sheave, the cabin moves smoothly up or down to the selected floor.
The main steps in the process are as follows:
- Traction motor activation: The motor starts and provides power for movement.
- Rope and sheave movement: The steel ropes slide over the sheave, creating motion.
- Counterweight balance: The counterweight moves in the opposite direction to balance the load and save energy.
- Cabin travel: The cabin rises or descends smoothly to the desired level.
- Braking system: Safety brakes ensure the elevator stops gently and securely at each floor.
What are The Different Types of Glass Elevators?
Glass elevators can be designed in several ways, and the differences are most clear when we look at the shaft structure and the cabin shape. Each option has its own build and set of features.
By Shaft Structure
Open Steel-structure Shaft
Open steel-structure shafts are built with a visible steel frame and glass panels that leave much of the structure open. This openness provides riders with nearly unobstructed views and makes the elevator a striking feature of the building. Because the framework is lighter and less covered, it often requires fewer materials. The trade-off is that it offers less protection from wind, rain, and other weather conditions.
Enclosed Steel-structure Shaft
Enclosed steel-structure shafts use a complete frame of steel columns and beams, with all sides sealed by glass or similar panels. This design creates a closed environment that shields both passengers and machinery from outdoor elements.
By Glass Elevator Shape
Semi-circular Glass Elevator
A semi-circular glass elevator has a rounded front made of curved glass panels. The design gives passengers wide-angle, panoramic views and creates a smooth, modern appearance. Building this type requires specially bent glass and a reinforced frame to hold the curve securely.
Cut-corner Glass Elevator
A cut-corner glass elevator is built with angled or chamfered corners, giving it a polygonal look instead of a strict rectangle. This reduces sharp edges inside, makes the ride feel more spacious, and adds a stylish, contemporary look that fits well with modern architectural layouts.
Square Glass Elevator
A square glass elevator is constructed with four straight walls at right angles. This is the simplest and most common design, easy to manufacture and install. Its regular geometry makes it versatile for both residential and commercial use, and it fits standard shaft dimensions without major adjustments.
What are The Steps to Install a Glass Elevator?
The process of installing a glass elevator spans several linked stages—from the first site assessment to final commissioning and handover.
Each stage protects structural integrity, passenger safety, ride quality, and code compliance.
- Evaluate Site & Technical Requirements — Check pit depth, headroom/overhead, shaft size, structural capacity, power supply, and local codes.
- Fabricate & Build the Shaft Structure — Erect the steel frame, set anchor plates/embeds, apply corrosion protection, and install/ seal glazing.
- Install the Guide‑Rail System — Set base plates, plumb and align rails, and fasten brackets to the structure.
- Install Traction Machine & Sheaves — Place machine beams, traction motor, overspeed governor, and sheaves; verify alignment.
- Fit Doors & Frames — Install sills, headers, frames, landing doors, interlocks, and make fine adjustments.
- Install Counterweight & Glass Elevator Car — Assemble car frame/platform/door operator/glass panels; mount counterweight and guide shoes.
- Rig & Tension Ropes (or Belts) — Cut to length, reeve over sheaves, make rope ends, equalize tension; add compensation if required.
- Wire the Electrical & Control System — Mount controller, run traveling cable, connect safety circuits, sensors, and limit switches.
- Test, Commission & Handover — Perform no‑load/load tests, governor trip, buffer test, door safety checks, leveling/ride tuning, and documentation.
Step 1: Evaluate Site & Technical Requirements
Before installation, confirm that the building can safely accept a glass elevator. Verify pit depth (for buffers and clearance), headroom/overhead (for car top clearance and equipment), and shaft size (clear widths/depths).
Check structural capacity of floors/walls for steel frame anchors and dynamic loads. Ensure power supply (e.g., 3‑phase service, grounding, emergency power where required) and plan drainage in the pit.
Review codes and standards (e.g., ASME A17.1/EN 81/GB) and site logistics (rigging paths, crane access). For outdoor units, assess wind, temperature, humidity, and UV exposure to select suitable materials and sealing systems.
Step 2: Fabricate & Build the Shaft Structure
Lay out control lines, set anchor/embedded plates, and erect steel columns and beams (bolted/welded).
Check plumbness and squareness within tolerance; tighten to specified torque. Apply corrosion protection (galvanized or primed/painted) and install glazing with gaskets and sealants while preserving required clearances.
Note: this work is typically performed by a qualified steel/glazing contractor and coordinated with the elevator installer.
Step 3: Install the Guide‑Rail System
Install rail base plates in the pit, then stack rails with fishplates, shimming as needed to achieve plumb and straightness. Fix rail brackets to the shaft at the specified spacing. Proper rail alignment is critical for ride comfort and noise control.
Step 4: Install Traction Machine & Sheaves
Set machine beams and anti‑vibration pads; place the traction motor and align the traction/deflecting sheaves. Mount the overspeed governor (and the governor tension device in the pit). Guard moving parts according to code.
Step 5: Fit Doors & Frames
Install sills, headers, and frames at each landing, then hang landing doors. Set clearances, adjust interlocks, and verify that door zones, locks, and indicators operate correctly.
Step 6: Install Counterweight & Glass Elevator Car
Assemble the counterweight frame and filler blocks; install guide shoes/rollers. Build the car sling and platform, mount the door operator, and fix tempered/laminated glass panels with certified clamps or frames. Balance the system according to the specified car and counterweight masses.
Step 7: Rig & Tension Ropes (or Belts)
Measure and cut ropes to length, reeve them over the sheaves, and make rope ends (e.g., wedge sockets/terminals). Equalize rope tension and, if required, install compensation ropes/chains to stabilize ride quality at higher travel distances.
Step 8: Wire the Electrical & Control System
Mount the controller, route the traveling cable, and connect the safety circuits (limits, governors, door contacts), sensors, encoders, and communication lines. Verify insulation, continuity, and proper labeling.
Step 9: Test, Commission & Handover
Power up and conduct no‑load runs, then perform rated and 125% load tests. Test governor overspeed, brake, buffers, and door protection devices. Tune leveling, acceleration, and deceleration for ride comfort. Complete documentation, perform final inspections, and train building staff on operation and basic maintenance.
Because installation requires specialized expertise, it must be performed by certified technicians. BDFUJI provides end‑to‑end guidance and on‑site technical support for glass elevator installations.
Glass elevator dimensions
The dimensions of a glass elevator are not fixed—they change with building type, usage, and design standards. To understand them clearly, it helps to look at the main elements:
- Cabin size – The inside space where passengers stand. In homes, a common size is about 1,000 mm × 1,200 mm, which fits 2–3 people. In malls or hotels, the cabin may be much larger, sometimes more than 2,000 mm deep, to carry groups of people at once.
- Shaft width – The total space needed to install the elevator shaft. This usually ranges from 1.5 to 2.5 meters, but high‑capacity glass elevators may need even wider shafts for structural support.
- Door width – The opening passengers use to enter and exit. Most are between 800 and 1,000 mm, but public buildings may require wider doors to meet accessibility codes.
- Overhead and pit depth – Overhead space (above the top floor) and pit depth (below the ground floor) are also critical. Typical pit depths range from 1–1.5 m, while overhead clearance can be 3.5–4.5 m or more depending on speed and capacity.
Here’s how they compare in a simple view:
| Factor | Residential Glass Elevator | Commercial Glass Elevator |
|---|---|---|
| Cabin size | ~1,000 × 1,200 mm (2–3 persons) | 1,600–2,000 mm+ (6–15 persons) |
| Shaft width | 1.5–1.8 m | 2.0–2.5 m or more |
| Door width | 800–900 mm | 900–1,200 mm |
| Pit depth | 1–1.2 m | 1.2–1.5 m+ |
| Overhead clearance | 3.2–3.8 m | 4.0–4.5 m+ |
For unique projects, BDFUJI offers customized glass elevators that adapt to specific building layouts, safety codes, and space constraints.
