As a result of several queries from our customers about the implementation of the new Machine Directive 2006/42/CE, GMV would like to expose some information we are certain it will be of interest.
Safety is a crucial element that any user should require as well as any company should be able to guarantee.
On December 2009 came into force the new Machine Directive 2006/42/EC (which implies lifting devices whose speed does not exceed 0.15 m/s). In the new Directive, under the heading of safety and reliability, is highlighted that “A breakdown in the hardware or software of the control system should not lead to hazardous situations”.
Currently, the products that the market is offering are in compliance with the old Directive, since presently the security settings required have been increased.
This which means that, at the moment, not all the valve groups of the market can offer the necessary guarantees to comply the new Machine Directive 2006/42/EC. A recent study
proves that in such cases a dangerous situation can occur in an elevator if a breakdown happens on the way up or down. At the present, some companies are supplying optionally a complementary system called releveling (electrical leveling recovery system to the floor). This system DOES NOT comply what is exposed on the safety and reliability section of the new Machine Directive. According to a study dated 07/09/2010, in case of a breakdown due to leak oil, with a speed lower than 0.20 m/s, and the safety device of the valve group remaing open, the cabin would fall down the pit without any safety devices performing for such action.
Nevertheless, the market does offer solutions to be in compliance with the recent Machine Directive 2006/42/CE to ensure security for the user and peace for the installation company. This is the case of the mechanical 3010 control units with 2CH, or control units with electronic valve groups like the NGV which incorporates two safety devices.
