3 Specifications, superstructure
3.1 Boom and telescoping mechanism
The main boom consists of 6 oval boom sections made from high-strength structural steel (δs=960MPa), providing the boom with super lifting capacity.
Main boom length: 13.8m to 61m
Max. Number of reeving: 18
All telescopic sections are automatically driven by a telescopic cylinder and pinned mechanically, extendable independently of each other.
3.2 Jib
The jib consists of two jib sections and one jib extension. The jib sections are reducing and lattice structured and the jib extension is constant and lattice structured. The jib can be combined to various lengths according to different requirements.
The jib cannot be attached with the vehicle during driving.
Jib length: 10.7m, 18m, 18.7m, 26m, 26.7m, 34m
3.3 Slewing table
The slewing table welded by high-strength structural steel (δ s = 960MPa) has high structural strength and super bearing capacity.
3.4 Rooster sheave
It is inserted at the boom head of telescopic boom section 5. This option is set up for rapid hoists over the boom head to improve the working efficiency when the loads are light.
3.5 Derricking mechanism
1 hydraulic cylinder with safety balance valve provides the boom with smooth derricking movements from -0.5° to 82°.
