The "Giant" Cat® 797 mining truck is 25 years old!

The largest in the world at that time

Mining truck

In 1998

Caterpillar officially launched the largest one in the world at that time

Mining truck - Cat® 797.

A huge body made of steel

It is equivalent to a three-story building of 418 square meters.

It can be called a "giant"!

A load of 360 tons is monitored by 8 computers.

The design and manufacture were completed in just 18 months.

Meet the industry's reduction

The demand for ton cost in large-scale operations.

Design and development

"Pass through five passes and slay six generals

Need an engine with over 3,000 horsepower?

Engineers overcame technical difficulties and combined two 3512B diesel engines into one, creating a high-horsepower engine, the 3524B.

Are all the tire sizes too small?

At that time, the largest tire available on the market could not support the huge body of the 797. Therefore, Caterpillar closely collaborated with Michelin to develop a radial tire with a tread width of 63 inches.

Must driver comfort be guaranteed?

The records describe the cab of the 797 as follows: "The cab of the 797 mining truck offers a home-like comfort level, equipped with power Windows, adjustable steering columns, air conditioning, stereo sound systems, and even a water cup stand."

Testing, production

"Done in one go!"

The Cat 797 was one of the first few devices designed in Caterpillar's virtual design center. Before the physical device was born, it began to undergo comprehensive testing in the virtual quarry. Subsequently, the 20 mass-produced 797s were put into use in various large-scale mining operations in North and South America.

Having roamed the world and weathered many battles

After 25 years of competing on the battlefield, Cat 797 has achieved the goal of reducing costs in large-scale operations with its outstanding performance, proving its "hard power". After several generations of upgrades, the third-generation model 797F has now achieved unmanned driving. Compared with trucks equipped with drivers, unmanned trucks equipped with the Cat Command automatic transportation system can increase their operational efficiency by up to 30%.

The cumulative operating time of the first batch of 797 trucks has exceeded 160,000 hours, and some of them are still in operation, continuing to help customers achieve success. Today, 25 years later, the Cat 797 remains a remarkable feat in the field of construction machinery and manufacturing.
