Energy supply

Machines or devices that serve as energy supply for the previously mentioned applications can be designed in various ways. They differ based on the length of the travel path, the medium to be transmitted, the frequency of movements, the speed of the consumer, or the specific application site.

Cables or hoses are used to transport the media within the transmission path from the feed-in point to the mobile consumer.
Machines and devices that meet the requirements for the above applications include:

• Cable drums or hose reels
  e.g., charging infrastructure for public transport
• Cable trolley systems or hose trolley systems
  e.g., overhead cranes
• cable drag chain or hose chain systems
  e.g., machining centers in metal processing

Cable trolleys, hose trolleys, cable chains or hose chain systems must be installed along the entire route of the mobile consumer and therefore have their natural limits, but can transport several media simultaneously via cables and hoses. As they do not require rotary transmitters or rotary couplings, they often have an advantage in terms of transmission safety. The disadvantage lies in the large number of bearing points, which are subject to continuous wear and therefore affect availability. Here, the place of use is often the decisive criterion for selecting the optimum energy supply system.
