Gear box
HW140C Lion

Gearbox HW140C Lion for 8 passengers lifts Speed up to 2m/s
Very compact and functional machine specially designed for the 8 passengers lift and speed up to 2,00 m/s, with rotor directly mounted on worm shaft, without connection fittings (A4) and hand wheel placed opposite to the motor. The body of the gearbox is made into two parts: upper and lower. Worm shaft running on high precision bronze bushings and on utmost quality ball bearings for the axial constrain. Worm wheel, running on roller bearings, is made by special alloy (centrifuged bronze with nickel) and traction sheave is made by spheroid cast iron (EN-GJS-700-2 UNI EN 1563). In particular, the worm shaft is carbon hardened, while the gear itself is characterized by very high efficiency with special surface treatment of flanks. Delivered with synthetic oil (3,5 litres) and standard single-phase 230V-50Hz fan, it has cantilever sheave (two fixation points, static load 3.100 Kg); outstanding characteristic is the possibility to completely disassemble the machine into sub-components (motor, flywheel, brake, sheave) for transportation, handling and installation in otherwise not easily accessible sites. Noise level below 60 Db (complying with IEC 39-4; CEI EN 60034-9), horizontal vibration level minor than 0,7 mm/s (complying with IEC 34 14; CEI 2-23) and electromagnetic brake with independent double action are characteristics that position gearbox HW140C “LION” as the avant-garde of the gearbox technology.
