Cat 814K wheeled dozer

Caterpillar begins first machine shipments this month of its new Cat 814K wheeled dozer.

Selling points of the 814K are the new, sound-suppressed cab, the power unit and transmission drive, and centralised service station configuration. Caterpillar says this “drives machine uptime and operator productivity to new levels”.

Isolation cab mounting plus seat air-suspension reduce machine vibration feedback to the operator. Operating noise levels in the cab are 71 dB, compared to 78 dB of its predecessor, with a sound-suppression package option to lower sound levels to 70 dB.

Inside the cab the first thing you might notice is that there is no steering wheel. The new fold-up STIC™ (Steering and Transmission Integrated Control System) armrest makes it easier to get into and out of the cab, while 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, Cat says.

The new touchscreen panel displays machine operating data such as system temperatures, fuel use and machine hours. The Vital Information Management System (VIMS) allows technicians to connect to the machine to access sensor information and machine data, to produce productivity reports etc. Cat Product Link offers remote access of machine operating data through the VisionLink interface to facilitate fleet management.

The Cat C7.1 ACERT engine meets EU Stage IV emission standards (and the USA’s EPA Tier 4 Final).

Engine Idle Shutdown and Auto Idle Kickdown avoid unnecessary idling to lower fuel consumption. 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 2.84-m3 straight blade delivers high production dozing on stockpile material and general earthmoving projects. Alternatively, the 10.5 m3 coal blade is good for lighter materials.
