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.
