A3 solutions from Wittur presented at Elevcon

Elevcon 2012

Wittur was present at ELEVCON 2012, the 19th Congress on vertical transportation technologies in Miami, FL, USA from May 22nd to 24th, 2012.
Marcel Hasenrader from Wittur Gmbh has presented a paper about “Recent developments in electronic safety gears: UCM solution”.
The development of electronic safety gears has enabled a new generation of “smart” devices, which act quicker and are triggered by different sensors concurrently, thereby realizing redundant safety systems totally independent from lift controller.
Utilising EOS electronic speed governor as a basis, Wittur achieved the first certified UCM A3 system solution available on the market.
Thanks to the computational power on board the EOS, identification of excessive acceleration and activation at low speed can be achieved; the different solutions available have been presented, including:
  • Solution #1: EOS and BSG-25P safety gear
  • Solution #2: EOS and gearless drive brake
