Caterpillar has improved operator comfort and performance efficiencies on its 814K wheel dozer, which now features a sound-suppressed cab, an efficient power unit and transmission drive, as well as a centralized service station configuration to provide better drive machine uptime and operator productivity.
A Caterpillar spokesperson said, “With its rugged structure designed to achieve multiple life cycles under the toughest operating conditions, the 814K delivers high production operation in applications like utility work at mines, heavy civil construction backfilling and grading work, and ground preparation and subbase work on airport and commercial projects.”
The wheel dozer’s upgraded cab design makes 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 with 78dB of its predecessor, with a sound-suppression package option to lower sound levels to 70dB.
Intuitive machine control
A new touchscreen information display provides intuitive machine control, displaying critical machine operating data such as system temperatures, fuel use and machine hours. The dozer’s information management system allows technicians to connect directly to the machine to access a wide range of sensor information and expanded machine data, so managers can create productivity reports, identify operator training opportunities, see data logging of machine parameters and diagnostic codes, and monitor machine health.
Powered by the Cat C7.1 Acert engine meeting US EPA Tier 4 Final and EU Stage IV emission standards, or Brazil MAR-1 emission standards equivalent to Tier 3 and Stage IIIA, the vehicle meets global emissions standards.
It also includes a range of features that reduce service time to maximize machine uptime. The machine’s new centralized 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 with easily visible fluid sight gauges reduces time spent on daily maintenance requirements.
