rotarX slip rings for cranes and hoists.
Slip rings are also used in crane technology for power and data transmission. Depending on the different types of machines, different tasks in crane technology are connected with the rotary transmissions. Under heavy duty conditions, all rotating components of the cranes (e.g. jib arms and grabs) must be reliably supplied with power and data in indoor and outdoor applications. The enormous reliability of the slip rings plays a major role, especially with high loads that are suspended above man and machine. The special gold wire technology of rotarX slip rings ensures long-lasting and trouble-free operation of the systems.

Common Applications for rotarX Slip Rings in Crane Technology:

  • Tower cranes
  • Bucket wheel excavator in opencast mining
  • Mobile cranes
  • Cable reels for gantry and harbour cranes
  • rotating superstructures fire engines
  • Excavator in construction
  • Pillar jib cranes
  • Attachments for cranes (jibs and grabs)

Power transmission for mobile cranes by means of slip rings

The modular system of rotarX slip rings offers maximum flexibility and a wide range of possible applications. The slip rings on mobile cranes and ladder trucks are used in the centre of rotation between the upper and lower structures. The electric drives and the sensors of the rotating booms must be safely connected in order to exclude risks for the operator. The rotarX slip rings offer the optimum solution for this. Hollow shaft slip rings also allow cables or hydraulic lines to be fed through the inside of the slip rings. Optionally, B-COMMAND also offers hybrid rotary transformers for the combined transmission of electrical power/signals and hydraulics.
