When people talk about elevators, one question often comes up — “Are all elevators hydraulic?” It’s a fair question. Most home lifts you see in villas or low-rise buildings use hydraulic systems, so it’s easy to assume every elevator works that way. But in reality, hydraulic is just one of several elevator types, each designed for specific spaces, heights, and needs.
Let’s take a closer look at how hydraulic elevators work, how they differ from traction and MRL systems, and when each type makes the most sense.
A hydraulic elevator works on simple fluid pressure. It uses a piston inside a cylinder, powered by hydraulic oil. When the pump pushes the oil into the cylinder, the piston moves upward and lifts the elevator car. To move down, the system releases the oil back to the tank, and gravity gently lowers the car.
This design makes hydraulic elevators smooth, quiet, and ideal for low-rise buildings — typically up to 4 or 5 floors. They don’t require a heavy counterweight or a machine room above the shaft, which makes them perfect for villas, duplex houses, and smaller commercial properties.
This simplicity makes hydraulic lifts cost-effective and easier to install compared to traction elevators.
Not all elevators are hydraulic — in fact, most high-rise and commercial lifts use traction systems.
Here’s how they differ:
| Feature | Hydraulic Elevator | Traction Elevator |
|---|---|---|
| Working Principle | Uses oil pressure and a piston | Uses ropes, counterweights, and a motor |
| Best For | Low-rise buildings, villas | Mid to high-rise buildings |
| Speed | Slower | Faster and smoother |
| Energy Use | More power going up, less efficient for frequent trips | More energy-efficient, especially with regenerative drives |
| Maintenance | Simple | Requires regular tuning of ropes and pulleys |
| Space Requirement | No overhead room needed | Needs overhead space for machinery |
Hydraulic lifts win on compactness and simplicity, while traction systems are better for taller buildings where speed and efficiency matter more.

For these reasons, many modern projects combine hydraulic lifts for private floors or villas, and traction or MRL elevators for commercial or multi-storey complexes.
MRL elevators use the same traction system but fit the motor within the shaft itself. This saves space and eliminates the need for a separate machine room. They’re now popular for apartments, offices, and compact high-rises.
Pneumatic elevators, on the other hand, move using air pressure differences. They’re compact, transparent, and visually appealing — often chosen for aesthetic home interiors.
Choosing between hydraulic and other elevator systems depends on a few key factors:
Hydraulic lifts are equipped with all standard safety features — from Automatic Rescue Devices (ARD) to door interlocks, overload sensors, and emergency valves that prevent sudden descents.
Regular maintenance is essential to keep oil levels, seals, and valves in optimal condition.

While prices vary depending on design, capacity, and materials, hydraulic elevators are typically more affordable at installation. They require less civil work, making them suitable for homes and smaller buildings.
So, are all elevators hydraulic? Definitely not — but hydraulic lifts play a vital role in modern architecture. They’re compact, affordable, and ideal for private residences or low-rise structures. Traction and MRL systems, on the other hand, dominate high-rise and commercial projects.
Whether you’re planning an installation for a new home or a commercial complex, the right lift depends on your building’s design, usage, and space availability.
At Evonic Pro Elevators Pvt. Ltd., we bring the right mechanism to every project — ensuring each system, whether hydraulic, traction, or panoramic, delivers smooth rides and lasting reliability.
Because the right elevator doesn’t just move you between floors — it moves your lifestyle upward.
Are elevators required in apartment buildings in India? The answer depends on building height, number of floors, and state lift laws. This guide explains when elevators become mandatory, how G+3 and G+4 buildings are treated, inspection requirements, and what apartment owners and associations should plan early to avoid approval or compliance issues.
Planning a G+3 or 4–5 floor building in Bangalore? This guide explains when a lift becomes mandatory under BBMP bye-laws, how common layouts are treated, and what owners should plan early—shaft, power backup, inspections, and maintenance—so approvals and daily use stay smooth. Includes answers and FAQs for homeowners and builders.
Elevator inspections in India are carried out by government-authorised lift inspectors under state lift laws. This guide explains who inspects elevators, what safety checks are involved, how often inspections are required, and why valid certification is essential for apartment buildings, commercial properties, and public safety.
