Definition of FLU and FLP
In addition to the most common installation types of unsupported (FLG_)_, unsupported with sag (unsupported with permitted sag) and sliding, there are others that have a few special features. Here we present two further installation types: the projected unsupported length FLP and the unsupported lower run FLU.
Self-supporting lower run FLU
What does unsupported lower run mean?
We speak of a self-supporting lower run FLU as soon as the lower run of the energy chain is partially unsupported. This type of installation enables a compact design in which the working area is as close as possible to the footprint of the machine - thus saving space.
Our recommendation: For short strokes of up to 2 m, it can be an attractive alternative to create more space while maintaining the same machine dimensions.
Special features of the self-supporting lower run
Tests from the test laboratory
Extensive tests make it possible to determine the additional loads of the most common energy chain series E4.1, E4Q or E2/000.
Projected unsupported length FLP
What does projected unsupported length mean?
In some applications, the energy chain is often used with a working path at an angle. For example, the projected unsupported length FLP installation type is often used in construction machinery or work platforms.
