<p>PURPOSE:To facilitate replacement of a cushion member by providing mountably/ demountably through a stop member the cushion member for relaxing a contact shock against an externally mounted boom on the peripheral surface in a base end part side of an internally mounted boom of the telescopic boom, and providing an opening part with cover opposed to the stop member on a base end part side of the externally mounted boom. CONSTITUTION:In a telescopic boom of an industrial vehicle for high lift work, a cushion member 13 for relaxing a contact shock against an externally mounted boom 11 is arranged mountably/demountably through a stop member 20 on a peripheral surface 121 of an internally mounted boom 12 extended/contracted relating to the externally mounted boom 11. On the other hand, in a base end part side of the externally mounted boom 11, an opening part 15 with a cover 151 is provided in a position opposed to the cushion member 13 when contracted the internally mounted boom 12. The cushion member 13 is arranged in a single row by each three quantity in an extending/contracting direction, to mount the cushion member 13 of each row in a base part 21 of the stop member 20. Thus by removing the cover 151, inserting a driver or the like from the opening part 15, operating a stop fitting 23 and mounting/ demounting the stop member 20, the cushion member 13 can be replaced.</p> |
