Application Of The Rotary Principle To Underground Mucking, Walter J. Smit

Bachelors Theses and Reports, 1928 - 1970

Since the beginning of man's utilization of rocks and minerals, he has felt a need for an efficient mover of these materials. Thus, he turned from the sole use of his hands to the development of the shovel, and through the other hand tools-- the hoes, and the fork, and the rake-- he finally came to the manufacture of the heavy, more efficient, large-scale rock movers-- the muckers, and the scrapers, and duckbill loaders.
