Start/stop roll-back eliminated
A 12-storey healthcare block at Sao Paulo Hospital in Milan has been equipped with a gearless winch-driven elevator supplied by leading Italian lift manufacturer Elex, using Unidrive drives from Control Techniques.
Elex has always pursued the highest possible performance and manufactures lifts that equal the highest quality lifts in the world.
At Sao Paulo Hospital, Unidrives are closely integrated with the Elex lift controller, giving seamless immediate response to calls. The lift’s load capacity is 1600kg, speed between floors is 1.6m/sec and the total travel over the 12 floors is 42 metres. In the event of a power loss, Unidrive activates an automatic return to floor strategy (RAP), automatically selecting the travel direction on the basis of an analysis of the current car load.
The customer's view
Thanks to integral brake management, motor control is synchronised during starts and arrivals, completely eliminating the momentary disturbing roll-back on start or stop and guaranteeing absolute comfort for Elex’s lift passengers.
