BOWLING GREEN, Ohio -- Many new, state-of-the-art machines will be unveiled at CONEXPO-CON/AGG 2011, but not every product being introduced will be modern. The Historical Construction Equipment Association (HCEA) is producing a 1:10 scale model of the 1841 Otis Steam Shovel, and will display the first production unit of the model at booth GL3138 in the Grand Lobby on March 22-26.

Designed in 1835 and patented in 1839, the Otis Steam Shovel is the earliest known land-based single-bucket excavator. Originally built for use in railroad construction by the firm in which inventor William S. Otis was a partner, it remained in production in small numbers until the early 1910s. The design concept of a railroad-mounted shovel whose boom swung approximately ninety degrees left and right was continued by several manufacturers into the late 1920s, and 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 levers, gears, drums and bucket trip, and comes on a section of railroad track for exhibit. It is the first of a series of scale models being produced exclusively for the HCEA, and will be shown courtesy of HCEA Board Chairman Dave Geis. Orders will be taken for a limited run of 49 more shovels; proceeds from sale of the models will help fund production of another model, a 1:16 scale Cletrac model F crawler tractor.
