Abstract
The tire removal machine comprises an upper member (15) which rigidly supports the rim of a wheel positioned coaxial to it, and is positioned at the top of a coaxial vertical rotary shaft (12) projecting upwards from a machine casing (11). The device of the invention comprises a support means (20) for supporting a wheel resting thereon, and transfer means for raising and lowering the support means (20) to move it from a first position, in which the means (20) is disposed close to the floor surface in order to receive/unload the wheel, to an upwardly raised position in which the wheel rests on said upper member (15), and vice versa.
Claims14
A tire removal machine for use on a floor surface comprising,
- an upper member (15) adapted to support the rim of a wheel in a coaxial position with the upper member, said upper member (15) being coaxially positioned at a top of a rotatable vertical shaft (12) projecting upwards from a machine casing (11),
- a lifting device having support means (20) for supporting the wheel resting thereon, and
- transfer means for raising, rotating and lowering the support means (20) from a first position, in which the support means (20) is disposed close to the floor surface to permit receiving or unloading the wheel when an axis thereof is positioned substantially horizontal to the floor surface to an upwardly raised second position on which the wheel is adapted to rest on said upper member (15) where the axis thereof is positioned vertically to the floor surface, and back from the second position to the first position
- wherein said transfer means has a lever mechanism, on which at a first end thereof carries the support means (20) and at a second end thereof is hinged on a horizontal axis of a slider element (31) which moves perpendicular to the floor surface and
- drive means (35, 55) for moving the slider element (31) between an upper and a lower position.
