The Historical Construction Equipment Association (HCEA) is a non-profit organization dedicated to preserving for public education the history of the construction, dredging and surface mining equipment industries. Over the course of many years, the HCEA has accumulated an astonishing amount of literature from dealers, manufacturers, and private individuals. All sales of literature are pieces of excess literature that we already have in our archives. All proceeds from sales help support the day to day operations of the organization. Help us preserve the history of the equipment that built our world.
