Caterpillar has unveiled the new 814K wheel dozer, which features an updated sound-suppressed cab, efficient power unit and transmission drive, and centralised service station configuration to drive machine uptime and operator productivity.
With its rugged structure designed to achieve multiple life cycles under the toughest operating conditions, Cat promises to deliver high production operation in applications like utility work at mines with the 814K.
The wheel dozer’s upgraded cab has been designed to make the operator’s workspace more comfortable and provides for more efficient machine operation.
Isolation cab mounting plus seat air-suspension safeguard against machine vibration feedback to the operator. The quiet cabin reduces operating noise levels to just 71dB, compared to 78dB of its predecessor, with a sound-suppression package option to lower sound levels to 70dB.
The new 814K is powered by the Cat C7.1 ACERT engine meeting U.S. EPA Tier 4 Final and EU Stage IV emission standards, as well as Stage IIIA to meet global emissions standards.
It also features engine idle shutdown and auto idle kickdown to avoid unnecessary idling; the new field-proven engine boasts 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.
The new 814K wheel dozer includes a host of features aimed at reducing service time to maximise machine uptime. The machine’s new centralised ground-level service area 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.
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.
The new 814K wheel dozer is currently available for worldwide orders, according to Cat. The first machine shipments are planned for June 2018.
