The Montanari M98 is an Italian-origin geared traction elevator machine designed for MR elevator systems with 2:1 roping, 3500 kg capacity and 0.50 m/s rated car speed. Its 18.5 kW motor, Γ520 mm sheave and 7x12 rope configuration provide reliable traction, stable torque transmission and comfortable ride quality for professional lift installations.
The Montanari M98 geared traction machine is designed for machine-room elevator systems where proven mechanical transmission, high starting torque and predictable service behavior are required. In this SKU, the machine is configured for 3500 kg rated capacity, 0.50 m/s rated car speed and 2:1 suspension. This makes it suitable for conventional MR traction layouts where the drive unit is installed in a dedicated machine room and connected to the elevator car through a traction sheave and steel wire ropes. The Γ520 mm sheave with 7x12 rope arrangement supports efficient rope contact and stable traction under load, while the 1/37 gear ratio provides the mechanical reduction needed to convert motor speed into controlled elevator movement.
From a construction perspective, the M98 belongs to the Heavy Duty Geared Traction Machine category. Montanari geared machines are selected in professional projects because their gearbox housing, traction sheave, shaft arrangement and braking assembly are engineered for durability, alignment stability and long service life. The machine body is typically built around a rigid cast structure that helps control vibration and supports the gear train under continuous load cycles. This is important in elevator applications because repeated starts, stops and leveling operations create high mechanical stress. The ergonomic design of the motor, gearbox, brake and sheave assembly also supports easier installation, rope alignment and routine service access inside the machine room.
Performance is based on a 18.5 kW motor with 37.5 A rated current. In modern installations the machine is normally paired with a VVVF inverter, allowing smoother acceleration, controlled deceleration and more accurate floor leveling compared with traditional direct starting. Although the catalogue line does not specify a formal IE efficiency class for every motor, these geared traction machines are commonly integrated into energy-conscious elevator systems through inverter control, correct counterweight balancing and optimized duty-cycle selection. The combination of motor power, gear ratio, rated speed and sheave geometry enables a balanced relationship between torque output, ride comfort and energy use. For this variant, the static load rating is 7000 kg, which must be checked against the total suspended load, roping factor and project-specific safety calculations.
Safety and maintenance are central to this machine type. The geared drive uses an electromechanical brake system designed to hold the car securely when stationary and to support controlled stopping under normal operation. Regular maintenance should include brake inspection, lining and air-gap checks, gearbox oil condition, seal inspection, bearing noise monitoring, sheave groove wear control and verification of rope tension. When maintained according to elevator service schedules, a geared machine such as the M98 offers dependable long-term operation and predictable spare-part planning.
This configuration is ideal for residential buildings, hospitals, hotels, commercial facilities, service lifts and heavier-duty projects depending on the selected capacity range. Lower-speed high-capacity variants are especially useful for goods elevators and industrial applications, while mid-speed configurations support passenger elevator projects where comfort, reliability and cost efficiency are priorities. The Italian origin of the machine adds value for buyers looking for established European traction technology with strong mechanical reliability.
