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. […]
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 […]
