The LTM 1300-6.3 is the latest 330-ton all-terrain crane by German-Swiss manufacturer Liebherr and sets a new record for carrying a 90-meter (275 feet) main boom within a 12 tonne (13.45 US ton) axle load. This model joins the company’s portfolio of 6-axle luffing jib cranes and features enhanced innovations to performance, comfort, and safety. Its capabilities exceed those of all other 6-axle cranes on the market.
A boom above
The 8-section telescopic boom – one section more than similar cranes in this class – extends to 275 feet. A wide range of lattice jibs is available to increase the overall reach up to 393 feet. Liebherr optimized the steel construction of the boom, outriggers and hook block so that the combined weight of those items can be carried on public roads within the 13.45 ton class.
The LTM 1300-6.3 includes Liebherr’s VarioBase® Plus rear outriggers, which are 6.5 feet wider than the front outriggers. This allows for greater load capacity over the rear supports and lighter overall weight for the front, which benefits the boom length. The 8-cylinder ECOdrive diesel engine develops 455 kW / 619 bhp with power transferred to the wheels via a 12-speed gearbox.
Economy with one engine
Liebherr has a history of using a single engine for driving and the superstructure, and that continues on the LTM 1300-6.3 with their ECOmode technology. ECOmode reduces fuel consumption and noise emission by automatically disconnecting the pump drive when the engine is idling. The conection is restablished quickly when lifting power is needed. With only one engine, the weight savings can be applied to the longer boom.
