The toughest mining world does require the help of various world-class heavy equipment that is known to be sophisticated with the best reliability in its class, as well as well-known products from Caterpillar, one of which is the Sheares EL1000. The advantages of the Cat EL1000 can be seen from its robust modular design with individual configurations equipped with the PMC-S control system. The system can provide protection through efficient shift control with complete data transmission, so the modularity of this machine has a unique mainframe which acts as the key to protection of the first unit in its versatility of application, especially when changing independent units. This mainframe is very selective in its overhaul due to high care so that not only protection is obtained but also maintenance is not complicated. The efficient maintenance consists of the ease of service of the EL1000 engine, durability when operating, and so on, so that it can support high productivity because it has been validated based on sheares testing in Germany.
High productivity is not only influenced by efficient maintenance, but also because of the maximum power generation. The impact of this is found in the high carrying capacity and cutting power, which are 1600 hp and 2×134 hp, respectively. With these two strengths, the EL1000 can be operated on low or medium coal seams due to its advanced automation and has been guaranteed by the haulage unit due to its high-power product with a mushroom range ranging from 1.6-3.9 m. Moreover, advanced automation makes cycle times more efficient, especially when working for consistent, face-to-face cuts to maintain manufacturing quality and reliability as with other Cat products. In addition, having professional service with genuine spare parts from the nearest dealer network can make cutting time more.
In fact, the overall design is also very influential on the reliability of the machine, especially the innovative design that is always applied by caterpillar as a differentiator between one product and another. In this EL1000, the innovative design provided is in the form of a trap shoe design which consists of two new parts, namely separate wear and structural elements. The design is tasked with reducing weight by handling the change from more than 500kg to less than 50kg. With lower handling, the machine is more flexible, more efficient as well because it can be carried out anywhere, handling is easier, and safety is guaranteed because of its independence in handling tasks in a shorter time. The various optimizations offered by the EL1000 certainly involve various developments including longwall operations. So that the series of shearers on longwall are successfully applied and enter world class with guaranteed security so that they can be used as solutions for subsoil mining.
