CONEXPO-CON/AGG show organizers are planning to bring in more than 20 pieces of historic construction equipment — some pieces more than 100 years old.

The Association of Equipment Manufacturers and the Historical Construction Equipment Association are helping facilitate the logistics of the display. In addition to mobile and construction equipment, the display also will include rock-processing equipment. Collector post cards telling the use, specifications and historical significance of each piece also will be on display.
