The GTB16EVO is a one-of-a-kind. It is equipped with four rollers with a unique form, positioned on the two sides of the wheel in diametrically opposite positions.
With ths system, the dismounting of the tyre with bead breakers is very simole ad natural: while the anterior bead breakers keep the bead in the drop centre, the posterior ones continue their course until the dismounting is complete.
The chucking unit is able to move not only clockwise and counter-clockwise, but also up and down. The clamping device is designed to clamp all kind of wheels.
The bead breakers are made in plastic material to prevent damage to the rim.
The machine is equipped with a patented lever to ease the mounting/demounting of the tyre.
The bead breakers are supported by two arms separately commanded. Each arm has two rollers, one conical which pushes on the bead and one cylindrical which pusches the side of the tyre.
