<p>A telescopic boom (10) suitable for a material handling vehicle is provided. The boom comprises two telescopic sections. One end (12a) of an inner tube element (12) is telescopically slideable in one end (14a) of an outer tube element (14) so that a majority length of the inner tube element can be received therein. An intermediate element (16) is also provided, a first end (16a) of which resides within, and is slideable in, the outer tube element (14). A second end (16b) of the intermediate element is telescopically slideable in the end (12a) of the inner tube element (12) that resides inside the outer tube element. A first stop (20) serves to limit withdrawal of the first end (16a) of the intermediate element from the outer tube element (14), whilst a second stop (18) serves to limit withdrawal of the second end (16b) of the intermediate element from the inner tube element (12). The provision of the intermediate element (16) allows a reduced overlap between the telescopic sections (12,14) thus increased reach.</p> |
