A Brief History of CONEXPO-CON/AGG
Historical Construction Equipment Association (HCEA)
Expansion beyond road construction inspired a name change to the Construction Equipment Exposition in 1960, finally ConExpo in 1975, the last to be held in Chicago.
In honor of CONEXPO-CON/AGG, here's a look at the 1925 Road Show. This year's attendees aren't going to see the unveiling of the brand-new Northwest Engineering crane line, or T. L. Smith dry batch pavers, Bucyrus and Byers shovels and Charles Hvass & Company asphalt and street maintenance equipment, or among the scores of new machines to be introduced this year.

Choosing the Right Central Tire Inflation System Can Increase Crop Yields with Reduced Compaction
Parker Hannifin Corp.
As farm machinery has increased in size, tire volume has also increased, but the overall footprint of the tires has not increased proportionally. As the load on each wheel increases, tires must be inflated to higher pressures to run safely.
The Parker CTIS can deflate tire pressures significantly lower than other systems while operating reliably over a wide range of temperatures and altitudes.

Telescoping Bowl Scrapers
Historical Construction Equipment Association (HCEA)
This technology was developed to eliminate needing the high power required to force the load down the entire length of the frame.
Not all of LeTourneau’s telescopic scrapers were unusually large. This Model LU Carryall has only an 11-yard heaped capacity, but this image shows the significant effect of the loading of the first of two buckets. It will soon be moved back, and the second bucket will load in its place.
