Cable Festoon System vs. Cable Carrier

Advantages of e-chain® systems

• Essentially maintenance free operation
• Decreased mechanical stress on cables
• No additional motors or controls required for long travels
• Roller chains  allow for a significant reduction in required drive force
• Approx. 50% less cable length required
• Cables are guided with a defined bending radius at all times
• Guide trough secures system from wind effects
• Easily add or replace cables as needed in the carrier
• Trolley speeds of up to 32.8ft/s and travel distances of up to 2,600 ft

Energy chain system review

Cable lengths/space requirements

• About 50% less cable
• Approx. 800mm system height
• About 10% less structural steel (cable festoon system)

Influencing the crane girder construction
No cable station required

Dynamic parameters
Rolling energy chains can be operated at a speed of over 600m/min and with an acceleration of over 2m/sec2  .

Secure cable guidance
Cables are safely guided in the energy chain and cannot get caught anywhere.

Cable festoon system review

Cable lengths/space requirements

• Approx. 115m cable (115% travel length) for 100m travel
• About 3,500mm length for the "cable loops"
• System height approx. 5,000mm

Influence on the crane girder construction
Cable festoon is required

Dynamic parameters
Cable festoon systems reach their limits at speeds of 240m/min. and accelerations of more than 0.8m/sec.2

Secure cable guidance
Cables hang uncontrollably and may get caught in the crane structure (e.g. by wind).
