LIEBHERR 81K – inovation, trends, efficiency.
Liebherr is introducing the 81 K at the 2010 ‘Bauma’ trade fair, a new fast-erecting crane of entirely new design, with the highest levels of performance. The 81 K sets new technological standards in its class, with many ingenious technical and visual features. The 81 K is the first crane in its class to operate only in the double-reeved mode – an absolutely new development that defines a new performance standard in this market segment.
The 81 K is the first crane in its class to operate only in the double-reeved mode – an absolutely new development called SPEED2LIFT. Since all the loads can be lifted in the double-reeved mode, the time-wasting process of re-reeving is no longer needed. Economical operation over an optimal range of loads and speeds is thus assured. The 81 K can be operated at the maximum possible speed and lift the maximum possible load, but can also run at high speeds when there is no load on the hook.
25% more lifting capacity
Compared with its predecessor, the 81 K has a distinctly improved load characteristic and can lift loads more than 25 % higher at the end of the jib. The user benefits of this mature design are also evident in its ease of control, the straightforward erecting procedure and the exceptional versatility.
All drive assemblies on the 81 K are continuously variable, using the frequency control principle. To ensure accurate movement of every load, the range of control lever movement always corresponds to the maximum possible speed. The pushbutton-selected fine positioning mode MICROMOVE reduces hoist speed to 25 %, so that even heavy loads can be positioned absolutely accurately without the hoist gear brake being applied.Liebherr 81K – Technical data:
