Quarry Trucks


Top Performance. Developed specifically for construction, mining and quarry applications, the 772 optimizes demands for lower cost per ton. Reliable, Durable, Dependable. Rugged construction and easy maintenance procedures ensure long life with low operating costs.

Mechanical Power Train

The Cat mechanical drive power train and power shift transmission provides unmatched operating efficiency and control on steep grades, in poor underfoot conditions, and on haul roads with high rolling resistance.


Pairing the Caterpillar seven-speed planetary power shift transmission with the C18 diesel engine with ACERT Technology delivers constant power over a wide range of operating speeds.

• Transmission Chassis Control (TCC)

Transmission shifting is based on Transmission Output Speed for optimum performance efficiency and clutch life. The TCC provides integrated functionality to controlled throttle shifting, directional shift management, neutral coast inhibitor, body-up shift limiter and body-up reverse neutralizer.

Throttle Lock

The operator can now electronically lock the throttle pedal at full throttle, to reduce fatigue on long uphill hauls. The throttle can be locked on by momentarily depressing the throttle lock switch located on the operator console, while depressing the pedal fully. The throttle is released whenever braking is applied or the throttle is again depressed.

Lock-Up Torque Converter

Combines maximum rimpull and cushioned shifting of torque converter drive with the efficiency and performance of direct drive. The torque converter includes: an additional clutch plate to maintain power train capability for higher horsepower and top speed, a new torque converter adapter that provides extra length to house the additional clutch plate and enables the converter components to be changed without having to change the housing, and a new sump oil level switch that serves as an emergency warning if oil is lost. The lock-up torque converter engages at approximately 8 km/h (5 mph), delivering more power to the wheels.

Lock-Up Clutch

Quickly releases and re-engages to reduce power train torque loads for smoother shifting, long life and a more comfortable ride.

New Differential and Proven Final Drives

The new Cat differential works with the proven final drives as a system to deliver maximum power to the ground. For improved serviceability, the pinion gear is cantilever mounted, which allows inspection of the differential without pulling the rear-end. Visual inspection of the pinion gear and bearings can be performed in 1-2 hours versus 8 hours on the previous models. In addition, the differential bevel pinion gear set is designed for improved adjustability, which results in improved contact patterns and life. The differential gear set also provides enhanced bending life for steeper grade applications.

New Differential Center Housing

A new, ductile iron center housing improves quality and reliability. The improved stiffness allows for better main support bearing life. The new housing also uses bolts, reducing maintenance time. This change also improves wheel station bolted-joint life.

New A-Frame

The new A-frame mounts directly to the spindles. The new A-frame eliminates the “king” bolt and includes a pin and bushing style mounting, consistent with the 777 and 793. This new design is simpler to maintain and service.

New Ductile Iron Spindles

A stress-optimized, ductile iron spindle is splined to the rear brakes, reducing brake pack rebuild time by up to two hours. In addition, the spindles are longer and wider with fewer seals for increased strength and durability.
