Rope shovels are used to dig and load material in surface mines. One of the main factors that influence theproductivity and energy consumptionof rope shovels is the performance of the operator. Existing methods of evaluating operator performance the do not consider relationship between production rate and energy consumption.

The shovel is offline 3.5 of the time and it propels to a new digging position 3.1 of the time. Siemens builds drive systems for electric shovels. The cycle time for an electric shovel differs slightly from a hydraulic excavator. For an electric shovel with a 70 swing radius, the cycle time averages 33.8 seconds, according to Koellner.
This refers to the number of shovel loads required to fill a haul truck. The norm in oil sands is 4 passes - i.e., 4 shovel loads are required to fill a dump truck. This is normally completed in less than 2 minutes ELECTRIC SHOVELS. Electric rope and pulley shovels are the workhorse of oil sands mining. Electric shovels are reliable and ...
Excavators typically feature a boom and arm, equipped with a bucket attachment that is used for digging. Unlike its cousin, the Mini Excavator , these units typically feature an enclosed cab for the operator and have the ability to dig at greater depths and distances from the machine.
Evaluation of Hydraulic Excavator and Rope Shovel Major Maintenance Costs in Operation. Author Creator Andreev, Rodion In this thesis, results of a comparison study of rope shovels and hydraulic excavators undertaken by the author between September 2014 and May 2015 is presented.
Hitachi Ultra-large Hydraulic Excavators satisfy the demands for reliability and durability to offer stable operation in various environments of large open-cast mines around the world. These products are also equipped on vessels and used to perform dredging, reclamation, marine civil engineering operations.
Mar 20, 2012 Working with a western Canadian coal operator, PampH Mining Equipment conducted a case study to compare the performance of its AC-powered rope shovel against its DC-powered shovel. The mine operates several PampH electric rope shovels and last year purchased two PampH 4100XPC AC shovels.

A performance monitoring study of an electric rope shovel operating in an open pit coal mine was conducted. As the mining industry moves toward higher productivity, profitability and predictability, the need for more reliable, productive and efficient mining shovels increases. Consequently, it is critical to study the productivity of these machines and to understand the effect of different ...
