How much clearance space should I leave in the e-chain?

Marco Thull | 7. July 2019

Cables and hoses to be routed in e-chains need sufficient clearance space . The following space reserves are required: Electric round cables          10%       Pneumatic cables                      5-10% Hydraulic cables                         20% Media hoses                           20%       Minimum clearances upwards and to the sides must be complied with. What are the filling rules for energy chains? […]

What does clearance height HF mean?

Phillip Hagedorn | 7. July 2019

The clearance height HF indicates the required installation height. All igus e-chain series are manufactured with pretension. In the clearance height section, you will find the measurement HF, which specifies the necessary clearance height, taking the pretension into account. HF = H + X HF = Required clearance height H = Nominal clearance height X […]

What is the difference between unsupported with straight upper run and unsupported with permitted sag?

Phillip Hagedorn | 7. July 2019

Since the e-chain is dependent on fill weight, we distinguish between three stages of unsupported length: 01) Unsupported length – straight FLG The e-chain is in the range FLG if its upper run is either still pretensioned, straight or has a maximum sag of half a chain link height. Installing in FLG is always recommended. […]

When do I take pivoting, and when locking mounting brackets?

Marco Thull | 5. July 2019

Pivoting mounting brackets are used as standard. In pivoting connections, a pivoting movement takes place between the mounting bracket and the first chain link. Locking mountig brackets are used in vertical standing applications – here, a locking connection is created between the first chain link and mounting bracket, which avoids a swing out of the […]

What is the upper run of an energy chain?

Marco Thull | 5. July 2019

The upper run is the upper part of an energy chain. In a horizontal linear motion, the length of the upper run changes continuously. For this reason, the maximum unsupported upper run length must be taken into account in a horizontal application. This depends on the chain series, the additional load and the max. speed/acceleration. […]
