A directive is a legal document established by the Council of the European Union. Each member state must then transpose it into its national law. The Directive is published in the Official Journal of the European Communities.
In the lifting sector, the Directive concerned is the Machinery Directive 2006/12/EC. This requires the presence on electric winches of an emergency stop and, in lifting, a limiter switch, as well as a load limiter above 1000 kg.
The European Federation of Materials Handling and Storage Equipment is an association of constructors and experts setting common rules for the design and use of handling equipment, including lifting equipment.
To determine the group for your lifting device, winch or block and tackle, three essential parameters are to be taken into account:
. Maximum load to be lifted:
. Load condition: it determines in what proportions the lifting device is used at maximum load or reduced load.
Thus a distinction is made between four characterised load conditions:
. Operating class:
This is the average operating time per day, on the basis of 250 working days a year.
These three parameters thus provide the means for classifying the devices into groups of mechanisms in accordance with this table you can use to determine the group for the lifting device you need :
Our technical sales staff is at your disposal to help you determine the characterised load condition corresponding to your case.
The degrees of protection gotten by the envelopes of electric materials low and Medium Average (until 1000V and 1500V) are defined by French standards NF INTO 60529 (IP) and NF EN 50102 (IK).
To symbolize the degrees of protection, it is made use of followed letters IP of 2 characteristic digits.
IP = code indicating the degree of protection gotten by the envelope against the access to the dangerous parts, the penetration of foreign solid bodies and the penetration of the liquids.
The first figure indicates the protection against the solid bodies.
The second figure indicates the protection against the liquid bodies .
A standard is a technical specification approved by a recognized body.
Unlike a directive, its application is not compulsory.
