Sycratronic

(„Synchronizing Crane Control System“) allows two Liebherr Mobile Harbour Cranes
to be operated simultaneously by one crane driver for improved speed, capacity and safety.
International safety standards require a down rating of crane capacity of 25% for manually opera-
ted, multiple crane lift operation if a synchronised movement of the cranes can’t be guaranteed.
With Sycratronic
®
no down ratings are necessary, i.e. both cranes can be fully utilized at maximum
lifting capacity.
In line with Sycratronic
®
Liebherr has developed another innovative add-on feature for heavy lifts.
The Vertical Line Finder is a control assistance feature which assists the operator in avoiding side
pull of the load caused from the long distance between operator and load or asymmetric centres
of gravity.
