Optimizing Ground Power Cable Management: M45D Motorized Cable Reel

400 Hz Cable System

Since its launch, the M45D has received wide attention as an automatic 400 Hz cable handling device designed to work with ground power units. It addresses common issues in ground power operations, including cable flexibility, labor demands, and safe storage. What makes the M45D different from conventional cable reels?

System Overview

The M45D is a double-drum motorized cable reel designed for aircraft ground power operations. It is composed of a motorized chassis, a dual cable drum assembly, and maximum 45m 400 Hz output power cable. Developed to support airport ramp environments, the system provides a reliable and efficient solution for managing long aircraft power cables while ensuring safe and orderly handling during use.
The purpose of the M45D is to improve flexibility during aircraft power supply. With automatic cable deployment and retrieval, it lowers labor intensity for ground personnel, and ensures that cables are stored safely and neatly when not in use. Proper cable management also helps prevent damage caused by dragging or improper storage, thereby extending cable service life and improving operational safety on the apron.

Typical Application with Fixed Ground Power Units

In service, the M45D is normally used together with a fixed ground power unit. It provides the cable connection between the GPU and the aircraft, delivering power over distances of up to 45 meters. When it moves away from the GPU, the cable automatically extends. This keeps the cable properly managed on the ground and allows the system to suit different aircraft parking positions.
Slip-Ring Technology

A distinguishing feature of the M45D is its use of slip-ring transmission technology.

Slip-ring technology was originally applied to the transmission of rotating machinery. Previously, with traditional cable devices, one end of the cable was fixed after connecting to an external power source, while the portion wound around the drum rotated with it. Due to the difference in rotational speed, long-term use could lead to wear at the connection point. However, cables utilizing slip-ring technology prevent the cable from being repeatedly twisted, thereby avoiding damage during winding cycles, significantly increasing service life of the cable.
Safety and Limit Protection

In addition, the system also incorporates limit protection mechanisms to ensure safe operation. The built-in limit sensor prevents over-retraction of the cable, reducing the risk of mechanical damage to the cable. Together with the motorized chassis and dual-drum design, these features allow the cable to be handled smoothly and reliably in busy airport environments.

The M45D Motorized Cable Reel provides a practical and reliable solution for aircraft ground power connections. It ensures long-term durability while simplifying routine power connection tasks, making it a dependable choice for ground support operations.
