Teach-In

feature, a semi-automatic system, which pi-

lots the crane from the vessel hatch to the quay without

any sway. Especially for bulk operation into hoppers, the

Teach-In

system increases turnover and ensures con-

sistent turnover rates during the entire ship unloading

The optimised interaction between powerful hydrostatic transmission and advanced Liebherr electronics ensures short,

productive working cycles in bulk handling. Independent of whether using a motor grab or a four-rope grab, all important

handling parameters such as the volume to be lifted with each grab, the opening/closing and hoisting speeds, simultane-

ous functions, winch synchronisation etc. are optimized using specially developed Liebherr electronics.
