The new Cat 725 ADT has a 26.5-ton payload and is designed, says Caterpillar, for application
in heavy and general construction, mining, quarry/aggregates, landfill, waste, and industrial
The new 725 offers improved lighting for night work, including optional high-intensity LED
working lights, LED machine-width marking lights, and access lights on both sides. The 20
percent larger cab features infrared blocking glass to reduce solar heating inside, says Caterpillar,
and sliding windows increase ventilation and enable communication with the loading-tool
operator and workers on the ground. A new automatic climate-control system is designed for
According to Caterpillar, the 725’s new cab is four times quieter than the previous cab, lowering
sounds levels at the operator’s ear to 69±2 dB(A). When the operator enters the cab, the
machine’s “wake-up” feature initiates the touch-screen display. The cab’s spinal roll-over
protective structure (ROPS) is designed to eliminate the structural pillar in the back of the cab to
provide enhanced rear-quarter visibility. Cab-mounted mirrors provide side visibility and can be
folded for transport.
Automated functions include assisted automatic hoist, which places the transmission in neutral,
applies the waiting break, and hoists the body to maximum tipping angle at high rpm. The
system, says Caterpillar, requires up to 50 percent less operator input. The system lowers the
body with a controlled descent to prevent “body slam.” The new Cat Detect with Stability Assist
is designed to reduce the possibility of rollover by giving the operator audible and visual alerts
when moving, and by inhibiting hoisting if the machine is at an unsafe angle while dumping.
The new 725 powertrain includes the Cat CX31 six-speed transmission and incorporates
advanced features to deliver smoother shifting, says Caterpillar, with up to 8 percent greater
acceleration and increased speed on grade—as much as 9 percent. Advanced Automatic Traction
Control removes all manual traction-control decisions from the operator, says the company, and
automatically changes the differential-lock engagement level, on-the-go, to continuously maintain traction.
Automatic Retarder Control, engaged in both forward and reverse, is fully
automated and manages retarding through a combination of hydraulic retarder, gear selection,
and supplemental application of the service brakes.
Standard Cat Product Link technology connects the machine wirelessly to the owner’s office,
says Caterpillar, allowing managers to monitor operating data such as location, hours, fuel use,
productivity, idle time, and diagnostic codes via VisionLink. External payload indicator lights
alert the loader operator when the truck is at capacity, reducing the risk of truck overloading and
subsequent tire and component wear, says the company. The optional Cat Production
Measurement system delivers payload information to the driver, loader operator, and office to
enable productivity tracking and analysis.
The 725 uses the Cat 9.3 ACERT engine with a 342-horsepower gross power rating. The
engine’s Cat Clean Emissions Module includes a diesel particulate filter (DPF) and a selective
catalytic reduction system to meet EPA Tier 4-Final/EU Stage V exhaust emissions standards.
Automatic, on-the-go regeneration occurs during normal duty cycles to clear the DPF. Eco Mode
can reduce fuel consumption by up to 5 percent, according to Caterpillar, and can be enabled and
disabled by the operator on the go.
Machine frames are designed to handle high torque loads, decrease hitch-area stress, and
optimize suspension geometry, says the company, and a new flexible fender design extends
component longevity and can reduce repair costs. The new 725 articulated truck’s universal
joints feature lifetime lubrication, and other lubrication points are grouped in the hitch area for
