拖管R68系列丨防碎屑，更高速，平稳运行。盖板沿外半径打开丨内高：45mm

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

A = moving end, B = fixed end
Pitch: 36mm
Chain links per m: 28
Travel: S
Tube length = ^S/₂ + K

K = Add-on for bend radius in the e-chain length calculation in mm
Note: Chain length for the chain links is rounded up, as there are no half links.

From 6m to max. 100m
Chain length = ^S/₂ + K2
Long travel - gliding (up to max. 100m)
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 4.0m and 6,0m, 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
