Shovel and dumper combination is a type of heavy equipment used in open cast mining operations. It is composed of two separate machines, a front-end loader (shovel) and a backhoe (dumper). The shovel is used to scoop ore, rock, or other materials out of the mine, while the dumper carries the load to a designated area for Shovel and Dumper Combinatio by Auqib Javed.pptx

Energy efficiency assessment of electric shovel operating in
The actual operating SPC of the electric shovel in an opencast coal mine of India is 0.14 kWh/cum whereas the minimum SPC is 0.12 kWh/cum for t idle = 0. Comparing the SPC with idle time and SPC without idle time, the energy saving potential is The spotting time of dumper is the time taken by it to position itself by the side of the. shovel for its loading. Normally, the spotting is done on one side of the shovel. The. spotting time generally ranges from 0.2 min to 0.5 min for rear dump trucks. depending on the operating conditions.Chapter 14 Shovel Dumper Estimation: Assumptions PDF
