PowerBoom: innovative increase of load capacity
The parallel PowerBoom system is a pioneering development from Liebherr. The simple mechanical add-on system increases the load capacity of large crawler cranes by up to more than 50 percent. The award-winning technology also delivers excellent value for money.
Massive increase in load capacity
The lattice sections are installed parallel to each other at the bottom section of the lattice boom of the PowerBoom system. This drastically increases the stability not only in the direction of the load but also to the side. The load capacity of long boom systems in particular can be increased dramatically by the P boom.
Operating with a luffing jib also allows massive load capacity increases to be achieved since the torsional moment is increased by the PowerBoom. This drastically extends the range of use of the crane.
Economic, flexible solution
In 2013 Liebherr received a design award from the International Construction Equipment Forum (ICEF) for its parallel PowerBoom system. The jury of experts particularly highlighted the economy and flexibility of the system in action.
The system is simple to retrofit - all crane operators require are two additional adapters. Standard intermediate lattice sections are used to form the parallel boom. The lattice sections installed in parallel are merged near the turntable using the lower P adapter and bolted to the crane. The upper P adapter reconnects the double boom. This enables the crane to achieve load capacities of the next higher crane class, delivering excellent value for money.
Perfect extension for the LR 11000 crawler crane
The parallel boom system is currently available for LR 11000, LR 11350 and LR 13000 cranes. The increase in load capacity has proved to be extremely effective on the compact 1000 tonne LR 11000 crane. Components from the luffing jib are used for the PowerBoom in this case. This keeps the sections of the main boom available for a particularly powerful luffing jib.
