Safety Solutions for A3 -
type-examined by TÜV SÜD
Bucher Hydraulics was first to successfully certify teir A3 safety valves by a renowned certifying body. There are three versions: A universal additional A3-valve, a solution combined with the LRV-1 and the revolutionary lift control valve iValve.
The required safety means
The new standard DIN EN81-2:2010 contains some specific changes that are generally known under the shortcut A3. Among other, a new safety means is required.
The means consists of three parts:
A) A sensor unit* that detects unintended movement of the car
B) A controller* that processes the signal and interrupts the power supply to the stopping element.
C) A stopping element that stops the movement of the car
As to date contactors fulfil this function.
Down:The car is stopped by
• the new, redundant safety valve „DSV-A3“, or
• The integrated A3-Function of the new, intelligent lift control valve „iValve“
The universal additional safety valve
The Double Safety Valve DSV-A3 is the new TÜV SÜD certified additional valve for protection from unintended car movement according to DIN EN81-2 2010. It can be used as an additional universal safety valve to any lift control valve of any manufacturer and has successfully passed type-examination by TÜV SÜD.
The safety valve DSV-A3 combined with the LRV-1
The DSV-A3 due to the new standard starting End of 2011 is combined by default with the LRV-1. Therewith the new standard's requirements are fully met.
The intelligent lift control valve iValve
The iValve combines simplicity, safety and intelligence. It is certified to correspond to DIN EN81-2:2010 and does not need any additional safety valve - The landing accuracy of ± 3mm exceeds therequired precision by far. The iValve
- is intelligent
- adjusts itself
- allows remote access over cable or wireless
- sets you ready for future
