The Haul Truck That Started It All: The Cat® 769

Our 769 was developed in the late 1950s, undergoing four pilot design stages prior to commercial production, which began in January 1963. The first machine was shipped on May 28, 1963. The new Caterpillar machine won head-to-head battles with the competition with higher performance, including a faster return, better weight-to-horse-power ratio, and lower cost per ton. And the 769 was soon the industry’s darling in the off-highway haul truck category – known for unmatched dependability backed by the Cat dealer network.  

In the Beginning 

The first machines were powered by Cat D343 diesel engines with 375 flywheel-horsepower and featured a revolutionary pneumatic-oil suspension system. Compressed air was used to dissipate impact on the truck’s frame, which extended the life of the frame. In addition, the trucks had a much smoother ride than other trucks in their class.

Always seeking to make our products better, engineers worked to improve the 769, and by 1964, the 769’s power was increased to 400 flywheel-horsepower. In late 1966, it was upgraded again to 415 flywheel-horsepower with the introduction of the 769B, featuring a V-bottom dump-box to reduce rear-end spillage

Lasting Legacy 

The 769 and 769B were the first of our mechanical drive haulers and set the stage for our entire line of Caterpillar off-road haul trucks that now dominate the market. 

Caterpillar Vice President of Load and Haul John Tuntland says, “Today’s Cat 770G stays true to the legacy of the original 769, a revolutionary off-road truck in its day. It’s a rugged workhorse made for the rigors of quarry mining. The 770G is popular among even the most difficult applications.”

A Satisfied Customer 

In 1963, Jack Gillen owned a mining and construction company and was working on a project in Carbondale, Pennsylvania. He had previously worked with several different makes of off-highway trucks and evaluated them under a wide range of conditions. 

Jack arranged for a performance comparison between the Cat 769 and a competitor 30-ton off-highway truck, and the results were impressive: The 769 hauled 54 more tons per hour and had a 29.5% production advantage.

Based on the test, Jack ordered six new Cat machines and said, “No truck I’ve seen comes near the Cat 769.”

Two years later, after working two 7-hour shifts per day, six days a week, Jack never looked back. 

“On the haul, the 769’s superiority really shows up … They’re still performing like new. Their reliability has been outstanding. They’ve racked up over 32,000 hours and given us better than 95% availability. No other truck we’ve used has come close to that. The 769 spots easier, loads faster, and dumps quicker.”
