The six-blade configurations on the new
With a maximum operating weight of 34tonnes, the 824K takes blades ranging from 5.04m³ to 16.13m³. The updated model is said to build on the performance of its predecessors with engineering refinements in its powertrain, operator station and structures, as well as features that enhance safety, serviceability and machine management.
The Cat VIMS 3G Vital Information System is integrated into the 824K wheeled dozer’s design to keep operators informed about machine operating conditions.
The model’s Cat C15 ACERT engine features an electronicallycontrolled fuel delivery system, an engine idle shutdown system to conserve fuel by limiting idling time, and a delayed shutdown feature to ensure that the engine is not stopped until operating temperatures have stabilised.
Drivetrain efficiency, fuel economy and travel speeds are further enhanced with the lock-up clutch in the Cat torque converter, reducing both drivetrain power losses and system heat. Two engine options are available that meet either US EPA Tier 4 Final emissions standards or Tier 3 equivalent emissions standards.
The electronically-controlled, 4F/4R Cat power-shift transmission can be set by the operator to automatically upshift or downshift based on machine speed. In addition, single clutch speed shifting controls allow the 824K to carry momentum through range shifts, for high productivity and fuel savings.
Both operating efficiency and operator convenience are enhanced with the left foot pedal, which serves as an engine decelerator, transmission neutraliser and brake, depending on the degree of application. As a decelerator, the left pedal allows the operator to temporarily reduce engine speed by overriding the throttle lock setting when manoeuvring around obstacles.
A new fuel tank is said by Caterpillar to provide a minimum 12 hours of operation, depending on the application. An optional tyre pressure monitoring system provides real-time information to the operator in the cab, ensuring proper inflation and optimising tyre life.
