Optimum pressure distribution and adaption 
of wheel sets on uneven surfaces
Mobility
•	 Outstanding mobility and manoeuvrability
•	 Curves at any possible radii and even slewing 
on the spot
Modular propping system
• 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
Hydraulic load distribution
•	 Hydraulic suspension avoids overloading of individual wheel sets
•	 Standard trailer tyres making requisition of spares economical and 
time-saving
• Increased lifetime of tyres due to individually steerable wheel sets
