The Insley Manufacturing Company produced heavy construction equipment, and was based in Indianapolis, Indiana.
History
The company was founded in 1907 by William Henry Insley (born 1870). The company holds many patents for cable-operated digging equipment such as Dragline excavators and power shovels. Insley lost its independence in 1975 when purchased by United Dominion Industries; the name is currently held by Badger Equipment Co.
