How do I calculate the chain length for a long travel?

Phillip Hagedorn | 3. July 2019

Lk = S/2 + K2 The e-chain glides on one half of the lower run and on the other half on a glide bar, as shown in the picture above. Lk = length of the e-chain S = length of travel S/2 = half length of travel R = bend radius ΔM = deviation from […]

What is an extension link and what does it do?

Phillip Hagedorn | 3. July 2019

The extension link is an additional link, which is connected to the two outer bands by means of crossbars. The extension link increases the possible load capacity (+50% per extension link) of an E4 energy chain series and also allows widths of up to 3,000 mm.  For more information, please contact us!

Why do I have to lower the suspension point in a long travel?

Phillip Hagedorn | 3. July 2019

A lowered connecting point is absolutely necessary for every gliding application: To prevent chain breakage through critical sag. To reduce wear (if the moving end is not lowered, there is more abrasion) Example: If we move the e-chain from right to left till the gap between the upper run and the lower run is 1mm, […]

What do I do if the unsupported length is exceeded?

Marco Thull | 3. July 2019

If the unsupported length of a series is exceeded according to the FLG diagram (fill weight, travel), the following options are available. Choose a more stable e-chain. Example: E4.42, additional weight 15 kg/m; travel/unsupported length: 5 m/2.5 m Under these conditions, the E4.42 is in “critical sag”. If an energy chain is required in the […]

Why is an angled moving end bracket beneficial?

Phillip Hagedorn | 3. July 2019

With a mounting angle between 3-5°, the e-chain is slightly forced downward by the push/pull force. This prevents the rising up of the e-chain. The angle of incidence of the upper run to the lower run is approximately 3-5°. This angle is also ideal for reducing wear. If the upper run is installed in parallel […]
