Grab operation
The robust design of Liebherr hydraulic crawler cranes combined with the high line pull of the main
winches is ideal for working with heavy grabs. Hydrostatically driven hoist winches with variable fl ow
hydraulic motors for optimum fi lling, precise lowering and emptying of the grab, automatically distribute
the load on both winches and convert the installed engine power into maximum hoisting speed even
when working with intermediate load.
When working with material handling grabs, the constant tension winch with free-fall prevents swinging
of the grab and ensures exact positioning of the material. In combination with the powerful swing drive
this results in quick work cycles and excellent turnover in material handling.
