“The igus E4Q.64L - same benefits at a lower cost”

The igus E4Q, a globally proven e-chain for applications with large unsupported lengths and high fill weight, now has a new variant: the "L".

Though the E4Q energy chain has established itself in demanding applications, it is often oversized in applications with medium loads. 

"To offer users advantages of the E4Q and at a lower price, we developed the L version - the E4Q.64L," says Christian Ziegler, Head of e-chain Product Management, igus. "Depending on the width, the low-cost version of the energy chain costs between 15 per cent and 20 per cent less than the E4Q."

Low weight, and three stop-dogs per chain link

The igus designers have modified E4Q's design. The side links are narrower thereby reducing the weight. Additionally, a rethought stop-dog system has come in place, with The E4Q.64L becoming the first igus energy chain with three stop-dogs per chain link, ensuring a regular power flow and a longer service life.

Up to 20 per cent more unsupported length

Tests prove that the E4Q.64L has an approximately 30 per cent greater breaking moment than the 14240 series, which is also used for unsupported applications. This results in up to 20 per cent more length with the same fill weight, and the increased strength enables applications, including car washes and airport passenger boarding bridges, cost-effectively.

The chain further offers a reverse bend radius (RBR), which means that circular movements can be implemented.

Adaptability

Keeping the E4Q's crossbars unchanged, has ensured that it can be opened just as easily, and has made available an extensive product range of crossbar widths. The E4Q.64L has been offered in 29 widths between 100 and 500 millimetres.
