The unsupported length depends on fill weight
X axis: unsupported length in m FLB/FLG
Y axis: fill weight in kg/m
Lower scale: travel S in m
FLB = unsupported with permissible sag
FLG = unsupported with straight upper run
Reference example A:
fill weight = 4 [kg/m]
unsupported length FLB = 1.75m
travel = 3.5m
A=moving end, B=fixed end
Pitch: 46mm per link
Chain links per m: 22
Travel: S
Chain length = S/2 + K
From 10m to max. 200m
Chain length = S/2 + K2Long travel - gliding (up to max. 200m)
Here the e-chain® is used with the upper run gliding on the lower run. We recommend letting our engineers support you when planning this type of system. In case of travel lengths between 7.0m and 10m, we recommend a larger unsupported e-chain®.
A1 = moving end
A2 = fixed end
A3 = Guide trough with glide bar
A4 = Guide trough without glide bar
A5 = Total length of the guide trough
