The new Cat 824K Wheel Dozer builds on the solid performance of predecessor models with engineering refinements in its power train, operator station and structures, and in features that enhance safety, serviceability and machine management. With a net power rating of 405 hp and a maximum operating weight of 74,966 lb., the 824K is available with six blade configurations ranging in capacity from 6.6 to 21.1 cu. yd. to customize it for production dozing, stockpile dozing or cleanup work.
The Cat C15 ACERT engine features an electronically controlled 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 stabilized. Drive train efficiency, fuel economy and travel speeds are further enhanced with the lock-up clutch in the Cat torque converter, a feature that reduces both drive train power losses and system heat.
The 824K design integrates massive, purpose-built structures and heavy-duty components that can support multiple rebuilds. The new dozer features a full box-section rear frame designed to resist twisting forces and shock loads encountered in heavy dozing.
teering cylinder mounts are designed to effectively dissipate steering loads into the frame, and axle mounts are heavy-duty components that contribute to the overall structural integrity. This robust design results in significant cost savings and sustained optimum performance over the life cycle of the 824K.
