摘要

The linkage has an upper hitch point (10) carried by a tripod structure. A foot (12) of the structure is connected to a rotary tool (1) by an anti-vibration elastic support (16). The tripod structure comprises a front arch (11) and a rear semi-arch (14) arranged perpendicular to a front cradle. The foot is connected to a chassis of the tool by the anti-vibration elastic support. The foot is connected to an intermediate structure (20) for bearing the chassis of the tool by the anti-vibration elastic support.
