4. Lifting
4.1 Working modes
Lifting chains are used to hoist or support a load, and to exert tensile force. Traditional applications include lifting forks on fork-lift trucks, suspending counterweights, maneuvering dam gates or transmitting traction force on drawing benches.
These examples show that lifting chains differ from conveyor chains in that they generally :
movements have little or no amplitude and/or speed;
movements are not continuous but intermittent, with periods ranging from a few seconds to several months, and have an outward and a return phase;
the chain can be continuously under load;
power is transmitted...

Standardization
Since 1989, a great deal of work has been carried out on power transmission standards with a dual focus:
a desire to extend ISO international standardization to all countries. ISO Technical Committee 100 seeks a compromise acceptable to all. As a result, France is gradually replacing its national mechanical chain standards with international standards:
- Chaînes...
