The data bus technology

Liebherr mobile cranes are completely interlaced by the data bus system. All important electric and electronic components are equipped with own micro pro-cessors and communicate with each other by only limited data cables. For the special demands of the mobile crane Liebherr has developed own data bus systems(LSB–Liebherr-System-Bus).Thedatabustechnologyimprovesthereliability,thecomfortandthesafetyforroaddrivingandcraneoperation:
