From Hitachi Construction Machinery to Caterpillar Inc, See What Works Best
Mining for gold has changed dramatically since the early days of exploration. The process in today’s standards consist of six phases (staking the claim; regional exploration, resource definition and feasibility study; assessment and approval; mine construction; operating the mine; and rehabilitation). However, the most exciting, and vital, part of gold mining is the operations.
The majority of gold today is found using two methods – open-cut mining and underground mining. Depending on which method is required, or where the gold is located, the equipment necessary can be quite large, complex, and extensive.
The two biggest and best machinery companies for gold mining are Caterpillar and Hitachi. While they both provide the necessary equipment for open-cut and underground mining, each company provides a little something different for the industry.
Caterpillar Inc. is the world’s leading manufacturer of mining equipment. Through its global organization, the American corporation provides a wide-range of mining equipment for surface and underground gold mining to the industry.
The company’s lineup for surface mining is comprised of: articulated trucks; conveyor systems; dozers; draglines; drills; electric rope shovels; highwall miner; hydraulic shovels; mining trucks; motor graders; off-highway trucks; wheel dozers; wheel loaders; and wheel tractor-scrapers. Underground equipment includes: conveyor systems; hard rock trucks; longwall; and room-and-pillar.
Caterpillar Conveyor Systems are built for an array of surface and underground mining applications, and are specifically designed for the unique geology and characteristics at each mine. Their purpose is to transfer ore over long distances at high capacities without disturbing environmental noise. The following criteria should be considered: profile, distance, material characteristics, tonnage, capacity required, and preferred speed.
Draglines are a primary excavating tool in surface mining. Caterpillar’s innovative draglines can operate 24 hours a day, seven days a week and are able to reach depths of nearly 300-feet. They provide the lowest material removal cost per ton and have an average operating life of 40 years. The company offers more than 45 dragline specifications that address specific gold mining needs.
Caterpillar offers two types of drills for gold mining – rotary blasthole drills and track drills. Each one serves a different purpose depending on the method of mining and the terrain. Rotary Blasthole Drills are proven to be more efficient with higher productivity levels and lower costs. Track drills provide most of the same features but with lower fuel usage. Both are field serviceable and Caterpillar provides the best customer service in the industry.
The machinery giant provides two types of shovels – electric rope shovels and hydraulic shovels. Each one is similar and different in a variety of ways. Electric rope shovels are used to load trucks with materials utilizing industry-leading visibility and the most efficient operating, loading, and hauling tools in the market. Hydraulic shovels provide high-volume productivity with faster cycle times with the ability to withstand any digging environment. The hydraulic feature increases uptime and low operating costs making it the premier shoveling tool for gold mining.
Caterpillar has a variety of machines for moving, loading, clearing, and grading mining sites.
Dozers, graders and wheel dozers are implemented to move large volumes of material in short periods of time. Caterpillars’ dozer trucks perform several valuable functions in surface and underground mining. These include: truck dump maintenance, ripping, stockpile management, stripping overburden, dragline support, trapping, and road building.
The company’s line of articulated trucks, mining trucks, and off highway trucks help to transport materials such as rock and ore at mines around the world. These powerful, productive, and integrated machines use the latest technologies and their engines provide optimum horsepower. Caterpillar trucks specialize in improving fuel efficiency while lowering emissions and shortening service time.
