Truck Cab Manufacturers Inc. (TCM) is an American manufacturer of truck cabs located in Cincnnati, Ohio.
TCM can trace its roots back to the formation of the Highland Buggy Company in 1870. Highland built some cabs for Seagrave Corporation in the late 1930s and early 1940s. John Weber, chief cab engineer for Trailmobile, Highland's parent company, bought the cab division and started manufacturing truck cabs under the Truck Cab Manufacturers name in 1948. The company was thriving by the 1960s as a designer and builder of cabs for heavy construction vehicles, cranes, cement mixers, airport vehicles and many other specialized uses.
In the early 1960s TCM introduced a rounded cab-forward 5 man canopy cab for fire service use. This new cab was 84" wide which was quite a bit larger than the 72-76" wide cabs many of the custom fire apparatus manufacturers were offering at that time. It was often called the Cincinnati Cab after TCM's home city.
The TCM cab was the basis for the International CO8190, and was used by apparatus builders like Pierre Thibault (Canada) Ltd., Howe, Oren, Hahn, Pemfab and Van Pelt, among others. TCM cabs were also used by custom builders like American LaFrance, Ward LaFrance and Pirsch, and chassis makers like Duplex, Oshkosh and Spartan.
TCM is the only manufacturer to produce a split-tilt cab, enabling longer lengths and higher weights in a cab-over configuration.
TCM continues to manufacture cabs for various builders today.
