The R 9250 is the first excavator of the new LIEBHERR mining excavator generation and the successor to the R 994 Litronic. Technologies already proven in the large mining models have been incorporated into this new excavator - in particular, the advanced design of the electronic, electrical and hydraulic systems and the robust and durable specification of the mechanical sections and constructional steelwork. In designing and developing this new production machine, LIEBHERR engineers have drawn on many years of experience gained from the deployment of the company's excavators throughout the world.
