HW135 VF

Gearbox for 3-6 passengers VVVF lifts Speed up to 1m/s.

Gearbox for 3-6 passengers VVVF lifts, speed up to 1m/s.

Very compact and functional machine specially designed for the 3, 4, 6 passengers lift and speed up to 1 m/s, with integral body and rotor directly mounted on worm shaft, without connection fittings (A4) and hand wheel placed opposite to the motor. Worm shaft and worm wheel are running on high precision and utmost quality roller bearings, worm wheel is made by special alloy (centrifuged bronze with nickel) and traction sheave is made by spheroid cast iron (ENGJS- 700-2 UNI EN 1563). Delivered with synthetic oil (2.9 litres) and standard single-phase 230V-50Hz fan, it has cantilever sheave (two fixation points, static load 2.300 Kg). 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 HW135 as the avant-garde of the gearbox technology. The machine is provided in a version that can be easily disassembled, removing motor, brake, traction sheave and fly wheel for easy transportation and installation into existing machine rooms, often located in not easily accessible places.
