Enclosed conductor system MKH

In order to reliably fulfill their transport tasks in closely clocked production processes, mobile consumers must not only be supplied with energy, but also be precisely controlled.

VAHLE has designed the MKH enclosed conductor system especially for this requirement. The contact-protected system can accommodate up to 10 poles and enables control signals to be transmitted in addition to the main current. The current collectors guided in the plastic profile and mounted on ball bearings compensate for even large tolerances. This makes the MKH the four-pole standard solution for crane systems, bucket conveyor systems and transfer cars in the low- to mid-power range.

The compact enclosed conductor system is easy to install and can be used both indoors and outdoors. An optional heating function prevents the formation of frost even in humid environments. In addition, the VAHLE APOS Magnetic positioning system can be fully integrated into the MKH housing.
