• Crane cab in corrosion-resistant, galvanized sheet steel
version, pouder-coated, with sound and heat insulating
internal paneling, interior of modern design, tinted window
panes all-round, front knockout window with large windscreen
wiper and wish/wash device, skylight of bullet-proof glas
with large parallel windscreen wiper and wish/wash device,
roller blinds on front window and skylight, space-saving
sliding door
• Greenish tinted front and side windows for heat absorbtion
• Pneumatic operated lateral foot board for safe access to and
from the carrier
• Crane cab tiltable to the rear by 20° to improve the sight
• 1 working projector 70 Watt, at the cabin front
Comfortable crane cab of outstanding
functionality
• Spring-mounted and hydraulically cushioned crane operator’s
seat with pneumatic lumber support and headrest
• Operator-friendly armrest-integrated controls, vertically and
horizontally adjustable master switch consoles and armrests,
ergonomical adjustable operating consoles
• Ergonomical control levers with integrated winch and slewing
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 2 )
• 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
Outstanding boom technology
