The Historical Construction Equipment Association (HCEA) will produce a 1:10 scale model of the 1841 Otis Steam Shovel, which will be on display at CONEXPO-CON/AGG 2014. The model will be found at booth L20012 at the west end of the Grand Lobby.
Designed in 1835 and patented in 1839, the Otis Steam Shovel is the earliest known land-based single-bucket excavator. It was originally built for use in railroad construction by the contracting firm in which inventor William S. Otis was a partner, and remained in production in small numbers until the early 1910s.
The design concept of a railroad-mounted shovel whose boom swung approximately 90 degrees left and right was continued by several manufacturers into the late 1920s. Its digging action is seen in today’s cable- and hydraulic-operated shovels.
The 1:10 scale model features a swinging boom, extending and retracting dipper stick, rolling wheels, and operational levels, gears, drums and bucket trip. The model comes on a section of railroad track for exhibit. It is the first in a series of scale models being produced exclusively for the HCEA and will be shown courtesey of HCEA National Director Dave Geis.
Orders will be taken for a limited run of the models. Proceeds from the sale will go toward production of a 1:16 scale model of a Cletrack model F crawler tractor.
