Abstract

A telescopic arm (12), comprising an outer cylinder (1˄) and multiple stages of inner cylinder (21 , 23), is provided on the distal end of a boom (4). The outer cylinder (13) has a telescopic cylinder (25) disposed thereon and telescopic stationary sheaves (31, 31 ') fixed thereon. The telescopic cylinder (25) is mounted on the outer cylinder (13) with a rod (25B) facing upward , and moves along the outer cylinder (13) with a tube (25A) as a free end. The tube (25A) of the telescopic cylinder (25) is provided with a sheave mounting fixture (30) and the sheave mounting fixture (30) is provided with telescopic movable sheaves (33 , 33 ). An expansion and contraction rope (34 , 34' ) is wound on the telescopic stationary sheaves (31 ,31 )' and the telescopic movable sheaves (33, 33 ).
