P1Roadsteering

Axle 1 is steered mechanically by using the steering wheel. The axles 2 and 3 are actively steered, depending on the speed and the front axle lock angle. At speeds of 30 km/h and higher they are set to straight-ahead position and locked.

P2All-wheelsteering

Using the steering wheel the axle 3 is turned in accordance with the steering angle of axle 1 to achieve the smallest possible turning radii.

P3Crabsteering

Axles 2 and 3 are turned in the same di-rection as the wheel lock on axle 1 by us-ing the steering wheel.

P4Reducedswing-out

The axels 2 and 3 are turned in accord-ance to the steering angle of the 1st axle that the swing-out of the chassis back is minimized.

P5Independentrear-axlesteering

Axle 1 is turned by using the steering wheel; axles 2 and 3 are turned indepen-dently of the wheel lock on axles 1 by control levers.

Comfort and functionality

Variable single cab concept

During road driving the crane cab is positioned and mechanically locked at the front of the vehicle by means of a telescopic beam. This results in optimal vis-ibility for the crane driver and a steering performance of a 2-cab crane. With the new concept of a movable cab Liebherr solves the problem of the limited vis-ibility of city cranes. Also on the right side of the vehicle the view is not limited, as the lower edge of the telescopic boom remains above the line of sight of the cranedriver.Bytheoptimalplacementofthesteeringleversfromthesteeringwheel to the first axle the LTC 1045-4.1 reaches the accustomed good steering qualityoftheLTMmobilecranes.
