Discover the largest machines ever used in the mining industry. Giant mining equipment such as stripping shovels and walking dragline shovels were at one time the largest machines to ever move on land. Packed with amazing photos, this book chronicles the history of the machines built from 1900 to 1971. The sheer size and mind-blowing capacity of these mining machines has won many fans. Also provides information about construction, operation, and maintenance. A necessity for earthmover or big-machine enthusiasts!
This book presents central problems in the design, research and maintenance of large-size mining machines for open pits, mobile earth-moving machinery, hydraulic hammers for mining and civil engineering, and screening processes for bulk materials. It brings together the insights of numerous respected academics to offer a thorough and multifaceted overview of the topic. The first few chapters of the book deal with specific problems that frequently occur in machinery for open-pit mining. They focus on the resilience of large-size mining machines, degradation of steels used for supporting structures, and modelling of large-size rotary joints, as well as the noise hazards in connection with degradation processes. The book then moves on to discuss problems arising in earth-moving machinery, such as new approaches to the assessment of operation and maintenance, dynamic loads in front-end loader booms, and synchronic transfer of power from the engine to the driven wheels. The book concludes by discussing hydraulic hammers for mining and civil engineering, and screening processes for bulk materials that combine a vibroscreen with additional feed elements. The book is primarily intended for undergraduate and graduate mechanical engineering courses, but will also be of interest to researchers and mechanical engineers.
This unique volume imparts practical information on the operation, maintenance, and modernization of heavy performance machines such as lignite mine machines, bucket wheel excavators, and spreaders. Problems of large scale machines (mega machines) are highly specific and not well recognized in the common mechanical engineering environment. Prof. Rusiński and his co-authors identify solutions that increase the durability of these machines as well as discuss methods of failure analysis and technical condition assessment procedures. "Surface Mining Machines: Problems in Maintenance and Modernization" stands as a much-needed guidebook for engineers facing the particular challenges of heavy performance machines and offers a distinct and interesting demonstration of scale-up issues for researchers and scientists from across the fields of machine design and mechanical engineering.
Bucyrus-Erie Company is a name synonymous with moving the earth. From the smallest loader-backhoe to some of the largest machines ever to move on land, no other company has produced such a wide variety of types and sizes of excavating equipment. With a rich heritage going back 128 years the company, now known as Bucyrus International Inc., is still designing and building some of the world’s largest shovels and walking draglines. Nothing could be more apt to describe this manufacturing power house than its slogan used in the 1960s “The Longest Line on Earth”. Over 450 spectacular black and white photos combined with detailed captions chronicle and describe all the major equipment product lines from Bucyrus Company, Erie Steam Shovel, Bucyrus-Erie and Ruston-Bucyrus. Every machine model from the extensive lines of cable excavators, hydraulic excavators, walking draglines, stripping shovels and drills is included, plus tables of machine introductions and production. There’s also detailed coverage of floating dredges, tractor equipment, cranes, bucket wheel excavators and other special machines. This book is sure to satisfy the serious equipment historian as well as the enthusiast.
