Elevator Types & Designs

MAC MRL A-6600

MAC MRL - Machine-Room-Less Elevators are traction elevators that do not have a dedicated machine room above the elevator shaft. The machine is installed within the hoistway and accessed from the top of the elevator car during maintenance.

The control panels are installed in a control room adjacent to the shaft at the top landing, typically within 150 feet of the machine. MRL elevators support travel heights up to 250 feet and speeds up to 500 feet per minute.

Machine-room-less elevators are ideal for mid-rise buildings due to their space-saving design, lower energy consumption, and reliable performance comparable to gearless traction elevators.

Adoption of MRL elevators has been slower in certain regions due to building code limitations regarding motor placement inside the hoistway. These regulations are evolving, and consultation with local authorities is recommended before specification.

MAC MR C-3300

MAC MR Geared Traction Elevators have a gearbox that is attached to the motor, which drives the wheel that moves the ropes. Gear-less traction elevators are capable of speeds up to 2,000 feet per minute and have a maximum travel distance of around 2,000 feet.

Door Opening	Center opening / Telescopic opening

MAC MRL G-4400

MAC MRL ADVANCE is a new generation elevator technology that uses permanent magnet motors for its operation. These gearless engines do not require a reducer, resulting in a compact, space-saving machine with high power output.

The motor is installed directly within the elevator shaft, reducing mechanical friction and significantly lowering operational noise. This design also improves ride comfort and system efficiency.

MAC MRL Advance technology enables energy savings of up to 50% compared to conventional geared systems. Gearless engines represent a modern evolution in elevator engineering, developed to enhance performance, reliability, and energy efficiency.

Type	MRL / MMR
Capacity	272kg – 1632kg (4p to 24p)
Speed	1.0 m/s – 4.0 m/s
Landings	2 – 30
Drive	Gearless PMSM / Frequency Controlled
Operation	Full Collective
Door Width	700 / 800 / 900 / 1000 / 1100 / 1200 mm
Door Height	2000 / 2100 / 2200 / 2400 mm
Door Opening	Center opening / Telescopic opening

MAC HYD H-2200

MAC Hydraulic Elevators are powered by a piston system installed at the bottom of the elevator shaft. The elevator ascends when hydraulic fluid is forced into the piston by an electric motor.

These elevators are best suited for low-rise buildings with 2–8 floors and operate at a maximum speed of 200 feet per minute. The machine room is typically located at the lowest level adjacent to the shaft.

Hydraulic Configurations

Conventional Hydraulic: Uses a sheave extending below the pit floor to accommodate piston movement. Maximum travel distance is approximately 60 feet.
Hole-less Hydraulic: Features pistons on either side of the cabin and does not require a pit hole. Travel distance ranges from 20 to 50 feet depending on piston type.
