Comfortable crane cab of outstanding
functionality

• Spring-mounted and hydraulically cushioned crane operator’s

indicators

• Modern instrument support with integrated LICCON monitor,

display of all essential operating data on the LICCON display
screen

• Additional heater with engine preheating

• 5-section, 60 m long telescopic boom in light-gauge design,

weight-optimized by FEM processing

• Material stability with high safety factors by the application

of ultra-high grain refined steels, boom bottom shell of

S 1100 QL (1100 N/mm

)

• Optimated, oviform boom profile with continuous curvature

in the bottom shell and upper offset joint, high stability against
deflection for maximum load capacities

• Outstanding functionality of the boom system due to the

automated, electronically controlled telescoping system
"Telematik"

• Patented internal locking system of the telescopes – reliable

and maintenance-free

• Optimal utilization of the telescopic boom due to a multitude

of telescoping variants

• All telescopes are also telescopable under partial load
• Y-guying system for the telescopic boom for a distinctive

increase of the load capacity

• The telescopic boom is always kept straight in its geometry,

ineffected by lateral sun radiation or side wind. For that
purpose, the stay ropes of the Y-guing system are wound
onto two accumulator blocks on the Y-frames by two rope
winches. Grips, pressed onto the stay ropes, define the rope
lengths in relation to the telescopic boom lengths; limit
switches control the positioning of the pressed-on grips; the
stay ropes are locked to the pressed-on grips by means of
tensioning rams in the Y-frames.

• Self-assembly of the Y-frames; carrier width/height with fitted

and laterally hinged Y-guying system: 3.03 m/4.07 m
