Formula | Explanation: |
---|---|
LK = S/2 + K | e-chain®® -length, all installation types, fixed end in the centre of the travel, except circular movements and most long travels (for FLG, FLB) [m]. |
LK = S/2 + ΔM + K | e-chain®® -length, fixed end outside the centre of the travel path (for FLG, FLB and ΔM) |
LK = [sup]S[sup]/2 + K2[m] | e-chain®® -length for long travel distances, fixed end in the centre of the travel distance |
SFLB = 2 * FLB | Calculation of maximum travel length, unsupported with sag |
SFLG = 2 * FLG | Calculation of maximum travel length, unsupported straight |
BRI ≥ Ba + 5 | Minimum guide trough width |
HRI ≥ 2 * ha | Minimum height of the guide trough for gliding application |
K = R * π + (2 x T) | Add-on for bend radius |
