In line with its innovative initiatives, Liebherr has brought a groundbreaking invention in the crane industry. It has introduced a novel boom formation technique for crawler cranes. The technique is believed to be more purposeful for wind farms that require huge amount of ballasts to elevate the boom.
The technique, which has been designed for crawler cranes, is particularly aimed at providing ease while erecting the cranes. The LTR 1220 can now be compressed to just few nominal plates – or in most circumstances, wholly removed, in course of elevation. The LTR 1220 substituted 280t of the 350t of frame counterweight that is needed to create and lower the SL10DFB key boom system that had a 153m main boom and 12m attached object. And the left 70t of counterweight plates are still needed for elevating regular wind turbine mechanisms.
During erection procedures, the knob slab of LTR 1220 remains reeved. Thereby resulting in the telescopic crawler being available for use soon after it has ended working as the LR166/2’s ballast.
In the crane industry, Liebherr has been introducing pioneering innovations since its inception. It is a German-based crane manufacturer that has brought so many innovations in crane application. For wind turbine mechanisms, Liebherr has developed an advanced approach for its LR 1600/2 cranes, which need long booms. The methods used in Liebherr crane repair services are being advanced in such a way that the needs of contractors can be met appropriately.
