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 aircraft such as A320, A350, B737, B787, B777, B747 ERJ 190 etc. as well as bias aircraft tires.

 The driven press tools rotate the wheel and at the same time break the bead by gently moving the tire sidewall inwards. 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)

The DUBB NGtronic® AUTO fully computerized version brings the additional benefit of an accelerated and optimized bead breaking process. Centering, height adjustment and bead breaking is performed fully automatically and avoids the risk of human error.

— KUNZ DUBB NGtronic® (semi-automated)

Once the operator has clamped the wheel, the positioning process is initiated by pressing and holding a dead man switch. Press tools move outwards automatically as well as centering and height adjustment of the wheel.
