Abstract

A telescopic arm ( 12) comprising an outer tube ( 13) and multistage inner tubes (21, 23) is provided in a distal end side of a boom (4). A telescopic cylinder (25) and arm extension fixed sheave units (31, 31') are provided on the outer tube (13). A sheave mounting member (30) is provided on the telescopic cylinder (25), and arm extension movable sheave units (33, 33') are provided on the sheave mounting member (30). An arm extension rope (34) is wound four times between each of sheaves (31A, 31B) of the arm extension fixed sheave unit (31) and each of sheaves (33A, 33B) of the arm extension movable sheave units (33). An arm extension rope (34') is wound four times between each of sheaves (31A', 31B') of the arm extension fixed sheave unit (31') and each of sheaves (33A', 33B') of the arm extension movable sheave units (33').
