SPECIFICATIONS – UPPERSTRUCTURE
A. Main boom and extend / retract mechanism
(1) The main boom has 4 hexagonal boom sections (1 basic boom and 3 telescopic
sections) made of high-tensile steel.
(2) The main boom head has 4 “sheaves”. You do not have to remove “wedges”
when you change line parts. A rooster sheave is mounted at the boom head.
(3) The boom sections extend / retract by a hydraulic cylinder and two sets of boom
extension / retraction ropes. The cylinder has a balance valve.
Min. main boom length (with sections fully retracted): 9800 mm / 32.15 ft
Max. main boom length (with sections fully extended): 31000 mm / 101.7 ft
Min. extend time: 70 s
B. Jib
(1) It consists of two jib sections. Jib section I is lattice structure (9 m long) and jib
section II is box-shaped structure (15 m long). The jib section II is secured into jib
section I, and the whole jib is secured onto the right side of main boom via
moveable pins during traveling.
(2) A sheave is assembled at the jib head.

D. Winch mechanism
(1) Main and auxiliary winches
(a) Main and auxiliary winches have the same parts, which include:

