Uninterrupted power supply at lorry ramps: safer logistics thanks to e-spool flex

KUALA LUMPUR, Malaysia - Oct. 30, 2025 - PRLog -- A single faulty power connection on a lorry ramp can halt an entire logistics operation. Traditional cable reels with slip rings are often the culprit, prone to corrosion and mechanical wear. To address this, igus has launched the e-spool flex, a revolutionary cable reel that eliminates slip rings, ensuring uninterrupted power supply even in demanding environments.

"Cable reels are standard in loading bays, but slip rings are a known weak point," says Michael Ditz, Product Manager Energy Chains at igus. "Our e-spool flex offers a fail-safe alternative."

Unlike conventional reels, the e-spool flex uses a spiral guide to manage cable movement, allowing a single uninterrupted cable to wind and unwind without twisting. The connector remains fixed, enabling seamless connection to trailer electronics such as lighting or ventilation systems. This design removes components vulnerable to corrosion, significantly improving reliability.

Tested in igus' 5,500m² lab in Cologne, the e-spool flex demonstrated a service life of approximately 10,000 cycles—equivalent to 14 years of daily use. Though the initial investment is higher than standard reels, its durability and reduced downtime offer long-term savings.

Available in various models, the e-spool flex supports cable diameters from 5 to 15mm and extension lengths from 5 to 25m. Options include manual cranks or automatic reeling systems with retention and braking features.

As logistics operations face increasing pressure and tighter schedules, the e-spool flex provides a dependable solution to keep trailers powered and processes moving. igus also offers a range of energy chains, bearings, and guides to enhance vehicle reliability across multiple touchpoints.
