Liebherr LTM 1250-6.1 - Manual (Page 8)

• Standard application programs: Safe load indicator (LMB),
configuration program with configuration image, telescoping
program with telescoping image, supporting force display,
control parameter program, test system; and as an option,
the work area limitation and the LICCON work planner
• Setting of the crane configuration by convenient
interactive functions
• Safe and reliable acknowledement of the crane
configuration set
• Representation of all essential data by graphic symbols on
the operating image
• With integrated wind speed control
• Reliable cut-off device in the event of exceeding the
admissible load moments
• Safe working load values for any intermediate boom length
• Winch indications for ultra-precise lifting/lowering of the load
LICCON computer system for control
and monitoring functions

6 Control of automatic transmission
• Telescoping by single-stage hydraulic ram with hydraulic
driving tenons (patented internal interlocking system)
• Telescoping procedure controllable by convenient operator’s
guide on the monitor, precise approach of the interlocking
positions
• Telescopable loads are displayed on the
LICCON operating image
• Rapid-cycle telescoping system with “automatic mode”, i.e.
all automatic telescoping of the boom to the desired length
• Particularly compact and light-weight telescopic system,
thus increased lifting capacities specially with long booms
at large radii
• Automatic cushioning in end positions during telescoping
and retracting for the preservation of the structural members
LICCON-assisted telescoping system
