Hydraulic vs Electric Home Lifts: Which Should You Choose?

How hydraulic home lifts work

A hydraulic lift raises the cabin by pumping fluid into a cylinder beneath or beside it. A motor-driven pump pressurises the hydraulic oil, extending a piston that pushes the cabin upward. To descend, a valve releases fluid back into the reservoir — the cabin lowers under its own weight, controlled by the valve.

The pump unit sits in a small utility area (the machine room) adjacent to the shaft, usually at the lowest landing. The system needs a pit — typically 150–300mm deep — to house the piston at its lowest point.

Hydraulic systems have been used in lifts for decades. They are mechanically straightforward, which can mean simpler fault diagnosis and repair. The trade-off is higher energy consumption (the pump runs throughout the entire up journey) and a requirement for periodic hydraulic fluid checks and replacement.

How electric traction home lifts work

An electric traction lift uses a motor mounted at the top of the shaft (or within it) connected to the cabin by steel ropes or flat polyurethane belts. The motor turns a sheave that moves the ropes, raising or lowering the cabin against a counterweight.

Because the motor fits inside the shaft, there is no separate machine room — hence the industry term MRL (machine-room-less). Pit requirements are minimal: some models need only 50mm, and a few are designed to be pit-less.

Electric traction is now the dominant technology in new residential installations globally. It draws power only when the motor is active, and some models recover energy during descent through regenerative braking. The result is lower running costs and reduced environmental impact compared to hydraulic systems.

Cost comparison in detail

A hydraulic home lift typically starts lower on purchase price — expect an indicative range of $25,000–$55,000 ex GST for a standard 2-stop installation, based on published Australian cost guides (hipages, supplier pricing; last checked April 2026). Electric traction models tend to start slightly higher at $30,000–$65,000 ex GST for a comparable installation, reflecting the more advanced motor and control technology.

However, the purchase price is only part of the picture. Electric traction lifts generally cost less to run (lower electricity consumption, no hydraulic fluid replacement) and may require fewer service visits focused on fluid-related maintenance. Over a 15–20 year ownership period, the difference in running costs can narrow or reverse the initial price gap.

Building works are the biggest variable for both systems. Constructing a new shaft, reinforcing floors, or excavating a deeper pit can add $5,000–$20,000+ to either option. Electric traction's smaller pit and no machine room requirement can reduce building works in retrofit scenarios — a significant advantage in existing Australian homes where space is tight.

Standards and compliance

Both hydraulic and electric traction home lifts in Australia must comply with AS/NZS 1735.18:2002 — the Australian Standard covering automatically controlled passenger lifts in private residences. This standard sets requirements for safety devices, emergency operation, car dimensions and controls regardless of drive type.

In most states and territories, lifts are classified as registrable plant under Schedule 5 of the model Work Health and Safety (WHS) Regulations. This means both the design and each installed unit require registration with your state regulator — SafeWork NSW, WorkSafe Victoria (which operates under OHS, not model WHS), WHSQ in Queensland, or the equivalent authority in your jurisdiction.

Your lift installer should handle the registration process, but it is worth confirming this is included in the quoted scope of works.
