Cat unveils new 814K wheel dozer

Caterpillar has equipped its new 814K wheel dozer with the best-in-class Cat planetary powershift transmission.

Offering four forward and reverse speeds to match application demands, the transmission is designed specifically for demanding mining applications.

Through the Cat-exclusive Advanced Productivity Electronic Control Strategy (APECS), the new 814K delivers consistent and smooth shifting, even when under load. APECS eliminates loss of momentum on slopes during gear shifts, so the dozer climbs grades more efficiently and with less fuel burn.

The 814K is powered by the Cat C7.1 Tier 4 Final ACERT engine. Featuring Engine Idle Shutdown and Auto Idle Kickdown to avoid unnecessary idling, the new field-proven engine features reduced fuel consumption compared to previous models.

As well, 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.

Two Cat blade design options offer tough dozing and rolling characteristics. The 2.84 cubic metre straight blade delivers high production dozing on stockpile material and general earthmoving projects. Alternatively, the 10.5 cubic metre coal blade provides precise and productive dozing, while helping to retain load control with increased capacity for lighter materials.

New cab

Isolation cab mounting, plus seat air-suspension, safeguard against machine vibration feedback to the operator. The quiet cabin reduces operating noise levels to 71 dB, compared to 78 dB of its predecessor, with a sound-suppression package option to lower sound levels to 70 dB.

Cab entry and exit is improved through integration of the new fold-up STIC (Steering and Transmission Integrated Control System) armrest. STIC delivers maximum machine responsiveness and control plus smoother, faster cycles, while minimizing operator movement to reduce fatigue, according to Caterpillar. Simple side-to-side movements turn the machine to the left or right, and gear selection control is operated through a finger-controlled rocker switch. Removal of the steering wheel console vastly increases operator space and improves forward visibility of the work area.

The new wheel dozer offers a upgraded touch screen display that features critical machine operating data, like system temperatures, fuel use and machine hours.

The dozer’s new Vital Information Management System (VIMS) allows technicians to connect directly to the machine to access a wide range of sensor information and expanded machine data. This allows managers to create productivity reports, identify operator training opportunities, see data logging of machine parameters and diagnostic codes, and monitor machine health. Cat Product Link offers remote access of machine operating data through the easy-to-use VisionLink interface to facilitate fleet management.

The machine’s new centralize ground-level service area provides quick access to the master disconnect switch with integrated lock-out or tag-out, DEF purge lamp for Tier 4 Final/Stage IV engines, circuit breakers, emergency fuel shutoff switch and jump start receptacle. Grouping of grease points for steering, hitch and rear axle trunnions along with easily visible fluid sight gauges reduce time spent on daily maintenance requirements.

By providing the operator with real-time operating data, VIMS system notifications alert operators and technicians of machine issues, so they can be quickly addressed before experiencing a significant downtime event. The machine’s new high efficiency hydraulic filtration results in cleaner hydraulic oil to increase component life and extends the oil inspection requirement by 50 per cent, from 2,000 to 4,000 hours. Railings, ladders and non-slip surfaces for platform level access points help to enhance technician safety when working on the engine and cooling system.

The new Cat 814K wheel dozer is currently available for worldwide orders. The first machine shipments are expected this month.
