Slip Rings for Cranes Excavators and Cable Reels

Crane superstructures, jibs, grabs and cable reels rotate under heavy load, indoors and outdoors, and everything hanging over people and machines depends on the power and data reaching the rotating side.

Industry Pain Points

What Goes Wrong on These Axes

Constraint 1

Loads suspended above people make the reliability of the rotating joint a safety question, not a convenience.

Constraint 2

Dust, rain, salt and vibration attack the joint continuously in opencast and harbour work.

Constraint 3

Fieldbus and fibre data now share the axis with the main power feed.

How INGIANT answers it

INGIANT units for crane technology are compact, easy to install and built for long operating time. They carry Profibus, Profinet and CANopen fieldbus signals as well as optical fibre, are available with protection up to IP68, and use noble contact materials for high conductivity and low starting torque in shock-resistant designs.

Typical Applications

Where These Units Are Fitted

  • Bucket wheel excavators in opencast mining
  • Mobile cranes and pillar jib cranes
  • Cable reels for gantry and harbour cranes
  • Rotating superstructures on fire engines
  • Excavators in construction
  • Crane attachments such as jibs and grabs
