The HD 1000, a semiautomatic tyre changer, is suitable for mounting and demounting truck, agricultural, industrial and construction equipment wheels up to a maximum width of 980mm. Operation is electrohydraulic and the controls are all located on a low-voltage portable unit.
The hydraulic power unit is installed on the machine to reduce floor-space requirements.

The hydraulic turntable, with two rotation speeds in both directions, has top-range design features and uses choice materials. It assures excellent clamping during the delicate wheel clamping, bead breaking and tyre demounting functions.

The new-design clamps allow operation on all types of rim, and above all allow a diameter of 110 mm to be clamped without any need for special adapters. The tool arm moves along the base for easier tool positioning during work. The new design tool arm has an overhanging bead breaker disc mounted on self-lubricating bushings to ensure durability and smooth travel. The disc's unusual shape has been specifically developed to allow the best possible penetration between the rim edge and tyre bead; what's more, its rounded external profile prevents damage to or jamming against the tyre wall.

The tool used is of tried and tested shape,
and has an effective protective coating.
