Marathon LeTourneau's L-1200, 22 Cubic Yard, Front End Loader

Extensive use of mining haulage vehicles with capacities greater than 610,000 kg (120 tons) has created the need for larger front end loaders. This paper describes the design of the L-1200 LeTro-Loader, rated at 17 m³ (22 yd.³), which incorporates an electric propulsion system integrated with an implement hydraulic system.
