DIFFERENT TYPES OF LIFTS
Hydraulic vs Belt-Driven vs MRL Elevators:
Which One Is Right for Your Project?
Here’s a detailed comparison between hydraulic elevators, belt-driven elevators, and MRL (Machine Room-Less) elevators,
highlighting their main differences in terms of technology, installation requirements, maintenance, cost, and use cases.
🔧 1. Hydraulic Elevators
Technology
Hydraulic elevators use a piston that moves inside a cylinder to lift the elevator cab. The piston is driven by a hydraulic fluid (usually oil) pumped by a motor.
Key Characteristics
- Typically used for low-rise buildings or homes.
- Requires a machine room (often located on the elevator shaft).
- Slower speed compared to traction systems.
- Requires a pit and space for the piston.
Pros
Lower installation cost.
Strong lifting power – can handle heavy loads.
Simple and robust technology.
Cons
Less energy efficient.
Oil leaks can occur.
Not ideal for high-rise applications.
🪢 2. Belt-Driven Elevators (aka Traction Elevators with Belts)
Technology
Instead of traditional steel ropes, belt-driven elevators use polyurethane-coated belts. These belts are durable and require less space to operate.
Key Characteristics
- Can be installed without a machine room.
- Suitable for mid- to high-rise buildings.
- Provides smoother and quieter rides compared to hydraulic systems.
Pros
Energy efficient.
Longer belt life compared to ropes.
Allows for more compact design and flexibility in layout.
Cons
Higher initial cost.
Requires more precise installation.
Maintenance of advanced control systems may be more complex.
🏢 3. MRL (Machine Room-Less) Elevators
Technology
MRL elevators eliminate the need for a separate machine room. The motor and control systems are installed within the hoistway, typically at the top.
Key Characteristics
- Typically use traction or belt-driven systems.
- Efficient use of building space.
- Ideal for buildings with height or space constraints.
Pros
Saves space – no dedicated machine room.
Lower energy consumption.
Good for both new construction and modernisation.
Cons
Maintenance can be more difficult due to limited access.
Can be more expensive than traditional hydraulic systems.
Limited to mid-rise applications in many cases.
