A conceptual cable-carrier loop occupies an envelope throughout its travel, beyond the mounting pattern.

Carbon Fibre Cable-Chain Supports: Reserve the Moving Envelope

A support for a moving cable carrier needs the carrier’s travel envelope, not just its mounting-hole pattern. Include the carrier and cable requirements supplied by their manufacturers, along with the moving and fixed attachment positions. A light support does not establish a suitable cable path.

Show the movement in the enquiry

Provide the relevant end positions and the space occupied during travel. Include the direction in which the carrier bends and the nearby equipment it must avoid. The support outline should be reviewed against the actual selected carrier rather than a generic loop drawn around the cables.

Keep cable requirements with the carrier

Igus’ installation guidance describes the need for cables to move appropriately inside a carrier and addresses strain relief and positioning. Use the instructions for the selected cable and carrier combination. Do not assign one bend radius from the carbon support dimensions or assume a free cable loop represents the installed carrier.

Check the handover configuration

Identify whether the order supplies only the carbon support, its hardware or a populated carrier assembly. In a movement demonstration, retain the carrier model, cable set and attachment condition with the record. Check the required operating travel under the agreed review scope; an unpopulated stationary photograph cannot establish the behaviour of the completed installation. Keep replacement cable information available for later service.

The populated cable set and attachment condition remain part of the movement review.
