Caterpillar unveil new 824K wheel dozer
Latest machine designed to deliver efficient productivity, long-term durability and optimum value
THE new Caterpillar 824K wheel dozer is said to build on the solid performance of its predecessor models with engineering refinements and features that enhance safety, serviceability and machine management.
With a net power rating of 405hp (302kW) and a maximum operating weight of 34,004kg, the 824K model is available with six blade configurations ranging in capacity from 5.0 to 16.2 cubic metres for production dozing, stockpile dozing or clean-up work.
Equipped with a Cat C15 ACERT engine, the machine benefits from 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 stabilized.
Drivetrain efficiency, fuel economy and travel speeds are further enhanced with the lock-up clutch in the Cat torque converter, a feature that reduces both drivetrain power losses and system heat. Two engine options are available that meet either US EPA Tier 4 Final/EU Stage IV emission standards or US EPA Tier 3/EU Stage IIIA equivalent emission standards.
For further drivetrain efficiency, the smooth shifting, electronically controlled, 4F/4R Cat powershift transmission can be set by the operator to automatically upshift or downshift based on machine speed.
In addition, the wheel dozer’s single clutch speed shifting controls allow the 824K to carry momentum through range shifts for high productivity and fuel savings. The machine is also equipped with steering and transmission integrated control (STIC) – a system that allows single-lever steering and transmission control. Simple side-to-side movements of the STIC lever provide up to 43° of steering articulation in both directions for precise manoeuvrability, and buttons on the lever provide fingertip control of directional and range shifting.
A primary focus on the 824K design is operator convenience and safety, such as providing light shallow-angle stairways for entering and exiting the cab and designing the STIC armrest to fold away for added room when entering or leaving the seat.
The wheel dozer also features a Cat Comfort Series air-suspension seat that has extra thick cushions and moves both the attached electro-hydraulic STIC-control pod and electro-hydraulic implement-control pod when adjusted.
To complement serviceability, Caterpillar’s Vital Information System, VIMS 3G, is integrated into the 824K design which keeps operators informed about machine operating conditions via a graphic display that features a touch-screen interface.
The machine also has monitoring capability through Cat’s Product Link system that provides event and diagnostic codes, as well as data such as operating hours, fuel level and idle time. This information is transmitted to a secure web-based application, VisionLink, which conveys information to machine owners and dealers, including working time, idle time and mapping functions.
