Caterpillar’s new 814K wheel dozer

Caterpillar’s new 814K wheel dozer features a redesigned cab, efficient power unit and transmission drive, and centralized service station configuration to drive machine uptime and operator productivity to new levels. Its rugged structure is designed to achieve multiple life cycles under the toughest operating conditions.

An upgraded cab makes the operator’s workspace more comfortable and enables more efficient machine operation. Isolation cab mounting and seat air-suspension safeguard against machine vibration feedback to the operator. The quiet cabin reduces operating noise levels to just 71 dB, compared to 78 dB of its predecessor, with a sound-suppression package option to lower sound levels to 70 dB.

Cab entry/exit is greatly facilitated through integration of the new fold-up STIC (Steering and Transmission Integrated Control System) armrest, which delivers maximum machine responsiveness and control plus smoother, faster cycles, while minimizing operator movement to reduce fatigue. Simple side-to-side movements turn the machine to the left or right, and gear selection 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.

Today’s 814K wheel dozer offers a newly upgraded touch screen information display for intuitive machine control. 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, view data logging of machine parameters and diagnostic codes, and monitor machine health and maintenance issues. Cat Product Link offers remote access of machine operating data through the easy-to-use VisionLink interface to facilitate fleet management.

The 814K is powered by the Cat C7.1 ACERT engine meeting U.S. EPA Tier 4 Final and EU Stage IV emission standards, or Brazil MAR-1 emission standards equivalent to Tier 3 and Stage IIIA to meet global emissions standards. Featuring Engine Idle Shutdown and Auto Idle Kickdown to avoid unnecessary idling, the field-proven engine boasts lower fuel consumption than 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.

Offering four forward and reverse speeds to match application demands, the wheel dozer boasts the best-in-class Cat planetary power-shift transmission. Through the Cat-exclusive Advanced Productivity Electronic Control Strategy (APECS), the 814K delivers consistent and smooth shifting, even when under load. APECS results in no loss of momentum on slopes during gear shifts, so the dozer climbs grades more efficiently and with less fuel burn.

Caterpillar also introduced new B-Prefix hydraulic hammers, which use a simple design that ensures reliability, versatility, ease-of-use and maintenance.

Available in B4(s) and B6(s) silenced, and B4 and B6 non-silenced versions, the hammers provide “plug-and-play” operation with a range of compact equipment, while delivering optimum life-cycle value. They are suited for skid steer loaders, multi-terrain loaders, compact track loaders, mini hydraulic excavators (3- to 8-ton operating weights), and backhoe loaders working in a range of construction and light-demolition applications.

Tool types for the new hammers include moil, cone, parallel and transverse chisel, and blunt, allowing the hammer to be adapted to an extensive range of applications. Matching Caterpillar-designed hydraulic kits are also offered and the best fit for Cat machines, providing customers a breaker package with superior design and benefits.
