Caterpillar 814K Wheel Dozer

June 4, 2018

The 248-horsepower 814K wheel Caterpillar dozer has an operating weight of 48,390 pounds. The straight blade pushes 3.7 cubic yards.

The cab has been upgraded with isolation cab mounting and seat air-suspension to reduce machine vibration. Operating noise levels have been reduced to 71 dB(A), compared to 78 with its predecessor.

The steering wheel has been removed, replaced with a foldup control system located on an armrest. The Steering and Transmission Integrated Control System (STIC) allows for simple side-to-side movements that turn the machine to the left or right, and gear selection control through a finger-controlled rocker switch.

The Cat C7.1 ACERT engine features Engine Idle Shutdown and Auto Idle Kickdown and has lower fuel consumption than with previous models. Load Sense Control Hydraulics provide on-demand hydraulic flow required by the implement and steering system to further improve fuel efficiency and deliver increased rimpull.

Four forward and reverse speeds match application demands, and the wheel a planetary powershift transmission, designed specifically for mining applications, the company says.

Two blade design options are available. The 3.72-cubic yard straight blade delivers high production dozing on stockpile material and general earthmoving projects. The 13.8-cubic-yard coal blade provides precise and productive dozing, while helping to retain load control with increased capacity for lighter materials.

The machine has a centralized ground-level service area that provides quick access to the master disconnect switch with integrated lock-out/tag-out, DEF purge lamp for Tier 4 Final/Stage IV engines, circuit breakers, emergency fuel shutoff switch, and jump start receptacle. Grease points for steering, hitch, and rear axle trunnions are grouped along with easily visible fluid sight gauges.
