Load handling – precise and safe, Multi-variable boom configuration system – Liebherr LTM 1250-6.1 User 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
