Undercarriage Mobility Modular propping system • Outstanding mobility and manoeuvrability • Curves at any possible radii and even slewing on the spot • Minimised stress and strain of undercarriage due to cruciform support base which directs the load path from boom tip to quay • Modular system allows further reduction of quay loads by installing additional axle sets • Easy adaptation to various sizes of support pads and bases longitudinally .5 12 diagonally m 1.8 m 5 5. m 6m m 12.

Practical solutions • The Liebherr Portal Crane, LPS, is an efficient combination of a space-saving portal (mounted on rails) and the proven mobile harbour crane concept. Particularly on narrow quays, individual portal solutions permit (railway) trains and (road) trucks to travel below the portal. Liebherr-Werk Nenzing GmbH P.O.
