Liebherr LTM 1250-6.1 - Manual (Page 7)

• 6-section, 72 m long telescopic boom for 72 m height under
hook and 66 m radius
• Optimized, oviform boom profile with continuous curvature
of the bottom shell and offset joint, high deformation stability
for maximum loads
• Broad boom profile for strengthening of the lateral bending
axis and stabilization of long additional booms
• Patented internal locking system of the telescopes – reliable
and maintenance-free
• High functionality of the boom system due to the automated
telescoping system ”Telematik”
• Optimal utilization of the telescopic boom due to a multitude
of telescoping variants
Load handling – precise and safe
oviform boom profile
70 m
• Telescopic boom T, 15.5 m – 72 m
• Swing-away jib K, 12.2 m long, biparted swing-away jib K,
12.2 m – 22 m long, extendable up to 36 m, mountable at
0°, 20° or 40°
• Special swing-away jib, 3.4 m long
• Fixed lattice jib TF, 14 m – 42 m, mountable at 0°, 20° or 40°
to the 51.9 m – 72 m long telescopic boom
• Luffing lattice jib TN, 17.5 m – 70 m, mountable on the
15.4 m – 67.5 m long telescopic boom with continuous
inclination between 82° and 68°
• Intermediate sections TF and TN equipment identical and
can be slid into one another for transportation
Multi-variable boom configuration system
• Jib A-frames with T-adapter and N-base section form a
complete transport unit and can be mounted with just 4 pins
• Easy-to-rig stay rods which remain on the intermediate
sections during transportation
• Auxiliary winch on the superstructure for easy reeving of the
hoist and luffing ropes
• Rigging of the lattice jib is practicable in suspended condition
on restricted sites
• Winch 2 for luffing operation of the jib
• Continuous load capacity interpolation during luffing of the
boom combinations TN between 82° and 68° inclination of
the telescopic boom
