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) is arranged on the outer tube (13) and arm extension fixed sheaves (31, 31') are fixed on the outer tube ( 13) . The telescopic cylinder ( 2 5) is mounted on the outer tube (13) with a rod (25B) facing upward, and moves along the outer tube (13) with a tube (25A) formed as a free end. A sheave mounting member (30) is provided on the tube (25A) of the telescopic cylinder ( 25) , and arm extension movable sheaves ( 3 3, 3 3' ) are provided on the sheave mounting member ( 3 O) . Arm extension ropes (34, 34') are wound around the arm extension fixed sheaves (31, 31') and the arm extension movable sheaves (33, 33'). (Fig. 5)
