At Kaiser Elevator, we’re often asked by developers, architects, and consultants: what’s the smartest elevator system for a new building—hydraulic or traction? The answer isn’t one-size-fits-all. Every vertical transportation decision is shaped by the unique pressures of cost, site constraints, code compliance, speed targets, energy use, and long-term operations. Drawing from our deep experience across residential, commercial, healthcare, and mixed-use projects, we’ll help you navigate the crucial differences and practical trade-offs so your specification aligns with your vision and lifecycle goals.
Understanding How Each System Works
Let’s briefly demystify the engineering at a practical level:
- Hydraulic elevators use a piston powered by fluid pressure. An electrical pump pushes hydraulic fluid into the cylinder, raising the cab. For descent, fluid returns to a reservoir, lowering the car smoothly. These systems have fewer moving mechanical parts and are structurally straightforward for building teams to coordinate during construction.
- Traction elevators rely on a set of steel ropes or belts looped around a sheave (pulley), balanced by a counterweight. The motor’s job is to shift the relatively small weight difference, which improves efficiency and supports longer vertical runs.
Quick Comparison Table
| Feature | Hydraulic Elevators | Traction Elevators |
|---|---|---|
| Lifting Mechanism | Piston, hydraulic fluid | Cables, pulleys, counterweight |
| Speed | Up to 150 ft/min | 200+ to 1,600 ft/min |
| Max Travel | Up to 60 ft (about 5-6 stories) | 300+ ft (over 20 stories) |
| Initial Cost | 15–40% less expensive (for low-rise) | Higher (more complex install) |
| Energy Efficiency | Lower; high usage on ascent | Higher; counterweight reduces load |
| Machine Room | Required (though compact options exist) | MRL (machine room-less) available |
| Best Building Type | Low-rise, high load | Mid/high-rise, premium speed, heavy traffic |
Installation & Initial Costs: What Developers Should Expect
Installation costs are typically a major factor influencing elevator selection early in design. We see:
- Hydraulic elevators cost less to install—often 15% to 40% lower than traction types. Their design means no complex overhead or deep pit, which can save on concrete, steel, and labor, especially for buildings up to five stories. Schedule gains are real, too. Hydraulic systems can be delivered and installed more quickly, supporting fast-track commercial and multifamily projects.
- Traction systems have a higher initial price, but may allow for a more compact hoistway in taller buildings and support space-saving layouts in mid- and high-rise towers. This can be critical for maximizing rentable square footage in urban infill sites.
Speed and Ride Experience
Speed and ride comfort are tied closely to elevator type, and they matter greatly for building users:
- Hydraulic cars max out around 120–150 feet per minute. For most low-rise multifamily, healthcare, or smaller public buildings where traffic is moderate, this is adequate. Consider ride quality—a modern hydraulic can run smoothly, but pumps may be noisier than traction drives, especially in start-stop mode.
- Traction designs routinely achieve 350–500 feet per minute (and up to 1,600+ for express elevators in commercial towers). They provide a quick, smooth, and quiet ride, essential to the occupant experience in buildings above five or six floors or in Class A assets prioritizing tenant satisfaction.
Travel Height & Code Considerations
Not all elevator types are suited for every building height. Code, function, and planning all factor in:
- Hydraulic systems are best for vertical runs up to 60 feet (about five or six stories). Above this, travel becomes inefficient and impractical. In retrofit contexts, above-ground hydraulic jacks may have even tighter limits.
- Traction elevators excel in mid-rise, high-rise, and supertall buildings—serving 20+ floors, campuses, or mixed-use towers. This flexibility is one reason most new high-density commercial projects lean toward traction packages.
All Kaiser Elevator solutions are designed to meet or exceed the latest American code requirements. For deeper planning guidance on incorporating compliance and value engineering from the start, see our article on code-compliant elevator packages.
Power Requirements and Energy Use
Long-term operational expenses have never mattered more to owners and sustainability teams. Where do these two systems differ most?
- Hydraulic elevators need significant power on ascent. The pump must overcome gravity every time the cab goes up—energy use climbs quickly in busy settings. Hydraulics draw much less power coming down and very little when stationary, but they’re not as energy efficient overall as traction types.
- Traction elevators, using counterweights, only move the load difference. This can cut energy use by about 20–40% compared to hydraulic systems in a heavily trafficked building. Regenerative drives, available in modern commercial traction systems, even recover braking energy.
If energy efficiency is a priority—or if your building has ambitious sustainability targets—traction systems (and especially regenerative drive options) are typically preferable for anything beyond low-rise operation.

Maintenance, Reliability & Lifespan
Choosing the right system also means balancing cost and care over decades.
- Hydraulic elevators have appeal for their mechanical simplicity—fewer moving parts often mean fewer wear points and simpler routine maintenance. But keep in mind that hydraulic fluid must be monitored, with potential for leaks or environmental issues from in-ground cylinders. Above-ground jacks mitigate that risk. With quality maintenance (monthly service is typical), a hydraulic can last 20–30+ years.
- Traction elevators involve more complex mechanics—ropes, sheaves, extensive safety apparatus—but generally deliver longer intervals between major service and are better suited to high-duty cycles. Well-maintained traction units can see 30+ years of reliable use, especially with systematic modernization and controls upgrades.

Suitability: When to Choose Hydraulic or Traction
Let’s map out a practical checklist for your next project. Based on what we’ve learned on active sites and with dozens of developers and owner teams, here’s when each system best fits:
Hydraulic Elevators are a great match when:
- Your building is up to five floors, such as smaller offices, mid-market multifamily, or healthcare centers.
- Heavy loads matter—think hospital beds, goods, or car lifts.
- You need to manage upfront costs and timelines tightly, often critical in the first phases of a new build or when holding costs are a concern.
- Traffic is primarily moderate, not continuous throughput.
Traction Elevators should be your go-to if:
- Your project rises above five or six levels (mid- and high-rise structures).
- Premium speed, ride comfort, and ultra-reliability are core, such as in commercial towers, high-end hospitality, or student housing.
- Energy efficiency is essential—whether to meet code, achieve certifications, or lower operational expense over long periods.
- You anticipate heavy traffic or have strict ADA/accessibility performance standards.
