Dragline excavators are heavy equipment used in civil
engineering and surface mining projects. A Variation of the same
basic machine is the Front Shovel excavator also used in Civil
engineering and Mining projects. The earliest machines were
steam powered and were the first mechanical excavators used by
man, in the 1800s. The steam shovel was invented by William S
Otis in 1835, and ran on rails with a boom that rotated on a
king post like a crane.They made possible projects like the
Panama Canal, and large dams.  The dragline was invented in 1904
by John W. Page of Page Schnable Contracting for use digging the
Chicago Canal. In 1912 it became the Page Engineering Company,
and a walking mechanism was developed a few years later,
providing draglines with mobility. Page also invented the arched
dragline bucket, a design still commonly used today by draglines
from many other manufacturers, and in the 1960s pioneered an
archless bucket design. In 1910 Bucyrus entered the dragline
market with the purchase of manufa
