Ladder Tower Company (LTC) or Ladder Tower is an American fire apparatus manufacturer located in Lancaster & Ephrata, Pennsylvania. It currently operates as a sub-brand of Spartan Emergency Response.
In 1973, Grove Manufacturing sold off its aerial ladder division to concentrate on crane manufacture. In 1974, Mahlon Zimmerman started a new company, Ladder Towers Incorporated (better known by the initials LTI) by building former Grove aerial devices.
Over the years, LTI built several aerial devices. Bodies were built by Conestoga Custom Products Incorporated, which was located in the same industrial park as LTI. Trucks were built on Spartan, Hendrickson and Pemfab chassis.
In 1985, LTI developed its own custom chassis, the LTI Olympian. In 1986, LTI was acquired by Simon Group, maker of the Simon Snorkel elevating platforms. The new company, called Simon-LTI, then acquired custom chassis manufacturer Duplex. The truck was manufactured under the Simon Duplex LTI name.
In 1998, Simon-LTI's ladder division was purchased by Aerial Innovations Inc., a company founded by LTI founder Mahlon Zimmerman.
In 1999, all these companies were merged into a division of the new American LaFrance Corporation owned by Freightliner Corporation. After this date, LTI and Aerial Innovations aerials were only built on American LaFrance custom chassis and Freightliner commercial chassis.
