Flat Crane Cable, YVFB / YFFB Type

Why flat beats round on a festoon

In a festoon or trolley system the cable bends in one plane only. A round cable in that duty builds up torsional stress that eventually makes it twist out of the carrier; a flat profile has no torsional stiffness in the bending direction, so it folds cleanly over the sheave and tracks straight through the trolley. It also stacks flat on itself, which reduces the loop height and shortens the festoon system.

Mixed cores in one profile

Because the cores sit side by side, a flat cable can carry very different cores in one body without the geometric compromises a round cable forces: power conductors at 25 mm² next to 1.0 mm² control cores next to a screened pair for a data bus. We can extrude the profile with the cores in any order, print the identification you need, and add a support element so the cable stays flat over long spans.

Applications

This construction is supplied into the following installations. Tell us which one applies and we will confirm the governing requirement.

Customisation

Core count and cross-section, screen arrangement, sheath compound and colour, print legend, length and termination are all built to order. Send the requirement — including the failed OEM part if this is a replacement — and we will propose the construction and confirm the lead time.
