A boom for a load handling machine, the boom has a mounting by which the boom is mounted on a body of the machine, and at least first and second telescoped sections. In use, the boom carries a load handling implement at or towards its outermost end. The first boom section is telescoped within the second section and is extendible and retractable relative to the second boom section by an actuator. At least the first boom section includes walls made at least predominantly of a composite material. A bearing member is located where adjacent walls meet to extend along a substantial length of the first boom section to provide bearing surfaces during sliding of the first boom section relative to the second boom section. Bearings also may be provided on the interior of the second boom section to further protect the first boom section.
A boom for a load handling machine, at least first and second telescoped sections, said boom being adapted to carry a load handling implement in use at or towards an outermost end of said first boom section, said first boom section telescoping within said second boom section wherein said first boom section is extendible and retractable relative to said second boom section, at least one of said boom sections includes a plurality of walls including a web made at least predominantly of a composite material, and bearing members where adjacent walls meet which extend along a substantial length of the boom section to provide bearing surfaces during sliding of said first boom section relative to said second boom section.
A section of a boom for a load handling machine, said boom section includes a plurality of walls each being a web made at least predominantly of a composite material, and bearing members which extend where adjacent walls meet along a substantial length of said boom section to provide bearing surfaces during sliding of said boom section relative to another boom section.
A load handling machine having a boom, said boom having a mounting by which said boom is mounted on a body of said machine, and first and second telescoped sections, said boom carrying in use, at or towards an outermost end of said second section, a load handling implement, said first boom section telescoping within said second section wherein said first boom section is extendible and retractable relative to said second boom section, at least one of said boom sections including a plurality of walls each being a web made at least predominantly of a composite material, and a bearing member where adjacent walls meet which extend along a substantial length of said at least one boom section to provide bearing surfaces during sliding of said first boom section relative to said second boom section.
