Features

Higher Productivity for the Long Run

Coal panels and face lengths are increasing – the average seam height is not. Maximizing productivity levels as the seam height diminishes requires the optimization of cutting power, haulage power, reliability, ease of maintenance and operator ergonomics. Enhanced safety features that address the challenges of mining lower seams also need to be provided. As the boundary conditions for longwall operations evolve Caterpillar continuously develops solutions that will safely maintain or boost your productivity. For low seam shearer applications the most compact Cat solution yet will be there to deliver the results you expect: the new Cat EL1000. This latest addition to the successful range of Cat longwall shearers will cover seam heights from 63 to 126 inches (1.6 to 3.2 meters).

Reduced Maintenance Times / Enhanced Safety

The new innovative two-piece trapping shoe design, with separate structural and wear elements, significantly reduces the weight to be handled during replacement from more than 500 kg (1,102 lb) for the typical trapping shoe to less than 50 kg (110 lb) per insert. This greatly improves the safety of performing the task itself while reducing the time required to complete it. Greater flexibility is another advantage. Because the weight to be handled is so much lower, change-out can be performed anywhere along the face since heavy lifting equipment, typically located only at the gate ends, is not required. The result: ease of handling and greater safety.
