Traction vs Hydraulic Elevators: How to Compare Lift Systems

Does “electric elevator” mean traction?

Ask suppliers to identify the lifting system in their proposal. A typical traction elevator uses an electric motor with ropes or belts, a sheave and a counterweight. A hydraulic system uses a pump, hydraulic fluid and a piston to lift the car. A hydraulic elevator also uses electricity to operate its pump, so the word “electric” alone does not identify the proposed system. Individual designs vary; see Otis’s explanation of lift operation.

What should I compare?

• Building and use: Consider required stops, capacity and accessibility needs.
• Space and preparation: Review shaft space, pit, overhead, equipment space and electrical requirements for the proposed model.
• Site suitability: Confirm the civil work needed on site and whether the building is existing or under construction.
• Performance: Compare each proposal’s specified capacity and speed with the intended use.
• Long-term cost: Review supply, installation, testing, warranty, maintenance and excluded work.

The system name alone cannot determine price, space needs or energy use. Compare actual product specifications and have qualified specialists review the building before deciding.

Does every hydraulic elevator need a machine room?

Requirements depend on the product and the site. Machine-room-less hydraulic products exist, but that does not establish availability for every project or supplier. Ask for the proposed model’s drawings and site requirements. Otis’s HydroFit product is an example from that manufacturer, not a SkyLift product claim.

Is traction suitable for my home?

A specialist can assess the number of stops, capacity, available space, accessibility needs and structural and electrical requirements. Other options may also be suitable depending on the project and available products. Request a site review and written comparison before committing to a system or altering the building.

What should a quotation explain?

The lifting system and model, capacity, speed, stops and door configuration.

Drawings, site requirements and who is responsible for civil and electrical work.

Supply, installation, testing and handover, schedule and written payment terms.

Warranty, maintenance, parts and any exclusions.

Project-specific regulatory requirements, confirmed against current applicable rules by qualified specialists.

Plans or photos help the initial discussion; they do not replace a survey and engineering review.

Common questions

Which is cheaper?

There is no fixed answer for every project. Compare equivalent specifications, site work, installation and maintenance scope, including exclusions.

Can an elevator be installed without a pit?

Pit requirements vary by product, design and applicable requirements. Ask for the proposed model’s technical requirements and have the site reviewed.

Does choosing a system replace a site survey?

No. Specialists must review the site, available drawings, intended use and required preparations before confirming suitability.
