TIRE BEAD BREAKING

KUNZ DUBB DYNAMIC UNIVERSAL BEADBREAKER

KUNZ DUBB Dynamic Universal BeadBreaker has been specially designed for the latest generation of radial tires, such as Michelin NZG and Bridgestone RRR tires for A340-500/600, A380 and B787.

The wheel is taken at the center hub by means of hydraulically operated clamping tools and is then lifted to working height. The driven press tools –as soon as in contact with the tire– rotate the wheel and at the same time break the bead and gently move the tire sidewall inwards. All steps of the process are electro-hydraulically controlled from the remote control box. There is no damage to the bearing cups or any other part of the wheel and tire.

The KUNZ DUBB is also available with a fully and semi-automated bead breaking process:

— KUNZ DUBB NGtronic® AUTO (fully-automated)
— KUNZ DUBB NGtronic® (semi-automated)


To clamp the wheel, special centering cones for the bearing cups are required. Our Universal Centering Cone is suitable for every wheel due to its conical shape.
