Abstract

A telescopic arm (12), comprising an outer cylinder (13) and multiple stages of inner cylinders (21 , 23), is provided on the distal end of a boom (4). The outer cylinder (13) is provided with a telescopic cylinder (25) and telescopic stationary sheave units (31, 31' ). The telescopic cylinder (25) has a sheave mounting fixture (30) mounted thereon and the sheave mounting fixture (30) is provided with telescopic movable sheave units (33 , 33 '). An expansion and contraction rope (34) is wound four times between each sheave (31A , 31B) of the telescopic stationary sheave unit (31) and each sheave (33A, 33B) of the telescopic movable sheave unit (33). An expansion and contraction rope (34' ) is wound four times between each sheave (31A 31B ) of the telescopic stationary sheave unit (31' ) and each sheave (33A ', 33IB' ) of the telescopic movable sheave unit (33' ).
