ABSTRACT:
A telescoping boom has a plurality of boom sections, and the boom sections nest together. The sections include an outer base section, intermediate sections, and an inner section that forms the outer end of the boom when extended. A hydraulic actuator and mechanical flexible links control the extension and retraction of the boom sections, and a hose carrier housing that is mounted as a subassembly carries hoses of sufficient length to carry hydraulic fluid under pressure from a base end of the boom to the outer end. The hose carrier housing supports the hoses folded into lengths in a zigzag form to provide sufficient length for boom extension. All connections to the hoses are accessible at the base end or at the outer end of the inner boom section. The entire hose carrier housing and the hoses are capable of being removed from and replaced into the boom as a unit.
