A work equipment (10) comprising a pole (20) for supporting a work apparatus (W), wherein the work apparatus (W) is placed at one end of the pole and the work apparatus (W) comprises:
- a casing (60) rigidly fixed to said one end of the pole (20),
- a work tool (55) disposed near said one end of the pole (20), and
- a motor (45) contained inside the casing (60) and adapted to activate the work tool (55),
- wherein the work equipment (10) further comprises a damper element interposed between the casing (60) and the pole (20) to dampen/absorb vibrations transmitted by the casing (60) to the pole (20),
- wherein the damper element comprises an annular body fitted onto the pole (20), the annular body (85) having an inner cylindrical surface facing towards the pole (20) and in direct contact therewith and an opposing outer cylindrical surface facing towards the casing (60) and in direct contact therewith, the annular body having two completely through radial openings (85R) extending from the inner cylindrical surface to the outer cylindrical surface, the two completely through radial openings (85R) separating the annular body (85) into two separated half portions arranged symmetrically with respect to a longitudinal median plane of the pole (20), each of which embraces a respective circumferential portion of the pole (20), each one of the two half portions comprising a first end facing the first end of the other one of the two half portions and distanced thereto so as to define a first passage opening therebetween, each one of the two half portions further comprising a second end facing the second end of the other one of the two half portions and distanced thereto so as to define a second passage opening therebetween, the first and the second passage openings being the two completely through radial openings (85R).
A work equipment (10) comprising a pole (20) for supporting a work apparatus (W), wherein the work apparatus (W) is placed at one end of the pole and the work apparatus (W) comprises:
- a casing (60) rigidly fixed to said one end of the pole (20),
- a work tool (55) disposed near said one end of the pole (20), and
- a motor (45) contained inside the casing (60) and adapted to activate the work tool (55),
- wherein the work equipment (10) further comprises a damper element (85) interposed between the casing (60) and the pole (20) to dampen/absorb vibrations transmitted by the casing (60) to the pole (20),
- wherein the damper element comprises an annular body fitted onto the pole (20), said annular body (85) having an inner cylindrical surface facing towards the pole (20) and in direct contact therewith and an opposing outer cylindrical surface facing towards the casing (60) and in direct contact therewith, the annular body (85) being made of a single piece and having a completely through radial opening extending from the inner surface to the outer surface, which is configured to allow the annular body to be enlarged during insertion onto the pole (20) before being elastically closed to firmly embrace the pole (20) once in position.
