Shipping lines and port operators demand high productivity rates in modern container ports. Port equipment must therefore prove extremely efficient and economic in use. Liebherr Container Cranes Ltd. has over 50 years of experience in crane development and manufacture. In 1958 Hans Liebherr founded the company in Ireland as the first manufacturing plant outside of Germany. At the Killarney plant in the Southwest of the country, the company produces ship to shore container cranes, rubber-tyred and rail-mounted stacker cranes, and accessories. Liebherr container cranes are in use in over 100 ports and nearly 50 countries worldwide.
