EXTENDIBLE BOOM WITH REMOVABLE HYDRAULIC 'HOSE CARRIER

摘要

A telescoping boom (20) has a plurality of boom sections (30,40,50,60), whitch include an outer base section (30), intermediate sections (40,50) and an inner section (60) that forms the outer end of the boom (20) when extended. A hose carrier housing (110) that is mounted as a subassembly (100) carries hoses and lines (142,144,150) to carry hydraulic fluid from a base end (30) of the boom (20) to the outer end (60). The hose carrier housing supports the hoses (142) folded into lengths in a zigzag from. All connections to the hoses (142) are accessible at the base end or at the outer end of the inner boom section (30), and the housing (110) and the hoses (142) can be removed from the boom (20) as a unit. The housing rests within an inner section but is not attached.
