A gearless elevator moves the traction sheave without a reduction gearbox. It can suit many residential and commercial buildings. The load, travel, shaft and power supply still need to fit the chosen lift. Share your building details to discuss a suitable gearless system.
A gearless elevator is a traction lift whose motor drives the traction sheave without a conventional gearbox. Ropes or belts link the lift car and counterweight through the drive system.
Many modern gearless lifts use a permanent-magnet motor and an electronic drive for speed control. The exact machine, suspension and controls differ by manufacturer.
Gearless refers to the drive machine. It does not tell you the car size, rated load, speed or whether a separate machine room is needed. Those details belong to the complete lift design.
In a geared traction lift, the motor turns the sheave through a gearbox. A gearless machine drives it without that part. Both are traction systems.
MRL means machine-room-less. It describes where the machine and control equipment sit. A gearless elevator can use an MRL layout or a separate machine room, depending on the system.
If your main concern is saving machine-room space, see the MRL lift page. For a machine or motor replacement, see elevator traction machines.
Do not copy the motor rating, lift speed or shaft size from a different building. Match those figures to the selected model and the site's design. Ask for a drawing that shows the full lift, not only the gearless machine.
| Project item | What to confirm | Why it affects selection |
|---|---|---|
| Rated load and cabin | Passenger demand, accessible use, items carried and usable car dimensions | Sets the size and duty the lift must handle |
| Stops and travel | Floors served, floor heights, total travel and required speed | Shapes machine, controller and suspension selection |
| Traffic pattern | Rush-hour demand, normal trips and the number of lifts in the building | Helps assess capacity and group operation |
| Shaft and door space | Clear shaft width and depth, pit, overhead and landing entrances | The car, doors and equipment must fit the building |
| Machine arrangement | MR or MRL layout, supports, machine position and service access | Changes the structural and access design |
| Electrical system | Incoming supply, earthing, drive, generator interface and rescue features | Requirements depend on the selected lift controls |
| Site environment | Heat, humidity, dust, ventilation and pit water risk | Affects equipment protection and placement |
| Safety and approvals | Applicable BNBC provisions, drawings, tests and manufacturer instructions | Must be resolved for the actual project before use |
The drive can be compact, but the car still needs a shaft, suspension path, doors, buffers, safe access and support for the selected system. These parts have to work together.
For a new building, review the lift layout before structural drawings are fixed. For a retrofit, measure the built shaft and check whether the machine and equipment can be brought to the installation point.
Confirm the equipment location and access needs.
Check the clear shaft, pit, overhead and door openings.
Coordinate rail brackets, beams and loads with the structural team.
Allow safe inspection of the brake, machine and controller after handover.
A gearless machine is one part of the installation. Supports, guide rails, counterweight, doors, controls and cable routes must suit the shaft. Site access also affects the installation plan.
Measure the shaft, landings, travel and access for equipment.
Agree machine position, supports, suspension and controller location.
Fit equipment and complete required mechanical and electrical connections.
Check operation, safety devices and the required commissioning records.

A gearless lift has no conventional reduction gearbox. It still has a brake, bearings, suspension, controls and safety equipment. Maintenance needs to cover the full elevator, not only its drive machine.
Follow the equipment's maintenance instructions. For broader support, see lift maintenance in Bangladesh.
A change in levelling, noise, door action or ride feel is worth reporting early. The fault may come from the drive or another part of the elevator.
Keep maintenance records for the installed machine, controller, brake and suspension. This helps the service team compare what has changed since the last visit.
A gearless lift can stop due to a door issue, drive fault, electrical supply problem, brake concern or control error. A fault code is a clue, not a diagnosis by itself.
If safe operation is in doubt, take the lift out of use and arrange inspection by a qualified technician. For a trapped passenger, follow the building's emergency procedure. Untrained staff should not attempt a rescue.
Component buying or machine replacement belongs on the traction machine page after the existing model and fault are identified.
A gearless elevator cost depends on the complete lift package and the building work. The motor type alone is not enough for a useful price.
Ask the supplier to show what is included: equipment, delivery, installation, testing, tax, building work and service terms. Compare quotes for the same load, travel, doors and finish.
Rated load, passenger demand, cabin size and accessibility needs
Travel height, number of doors, traffic and control requirements
MR or MRL arrangement, equipment support and maintenance access
Opening type, cabin materials, fixtures and selected options
Drive, electrical work, emergency functions and required testing
Civil condition, transport, installation, warranty scope and upkeep
These answers can help with an early enquiry. Final dimensions and features depend on the selected lift.
The machine drives the sheave without a reduction gearbox. This can cut losses in the drive and help with compact machine design. Actual energy use, noise and ride quality depend on the full elevator system.
No. Gearless is the traction machine type. MRL describes a layout without a traditional machine room. Gearless lifts can be designed with or without a separate room.
Yes, many residential and commercial lift ranges use gearless traction. The supplier must confirm the rated load, stops, speed, shaft, doors and traffic suitability for your building.
Yes. The machine brake, bearings, controller, ropes or belts, doors, guides and safety devices still need the checks set by the manufacturer.
The price depends on load, car size, stops, speed, MR or MRL arrangement, shaft work, equipment, installation and service terms. A site-based quotation is the best way to compare offers.
Provide the building plan, clear shaft dimensions, pit, overhead, stops, floor heights, intended load and power details. The lift supplier and building team should confirm the final drawings.
Share the floors, lift use, expected load and available shaft. Dhaka Lift Solutions can review the enquiry and discuss the machine layout and quotation scope.
