Liccon-assisted telescoping system – Liebherr LTM 1250-6.1 User 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

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
