Caterpillar has added the new AD22
underground truck to its hard rock mining
product line. The 22 t payload articulated dump
truck is the smallest in the Cat ® product line, yet
it is designed to deliver the productive
performance and durability of its proven, larger
counterparts. Its small operating envelope and
agile characteristics enhance productivity in any
mining application suited for this size class.
The AD22 makes best use of proven Cat
components, such as the C11 ACERT™ diesel
engine. The durable engine delivers gross power
of 242 kW to achieve superior speed
on grade. The new truck shares
major components
with a number
of Cat
machines to
help ensure good
parts availability and
reduce inventory costs.
Joy Global’s 22HD LHD offers a bucket
capacity of 9 m 3 , static tipping loads of
48.2 kN, a breakout force (tilt) of 350 kN and
an operating weight of 58,968 kg
The wide body design makes loading faster
and easier. Multiple dump body sizes are
available to optimise the truck for all mining
applications suited to this size class.
The AD22 also takes advantage of Caterpillar
ergonomic designs to create controls and
instrumentation that help operators perform
efficiently. An easy-to-read full colour LCD
screen displays machine status.
Prior to the AD22 launch, Caterpillar Underground
Mining (CUGM) had acquired the intellectual
property of underground articulated truck designs
from Ground Force Worldwide. This provides
Caterpillar with additional design options in the
20 t and smaller payload class. The Ground
Force AT18E (18 t payload ejector) and AT20 (20
t payload) remain available for immediate order
via Ground Force Worldwide. The company
showcased the AT18E at MINExpo 2016.
This acquisition followed the September 2015
announcement of CUGM acquiring the
intellectual property of underground articulated
truck designs from Specialised Vehicle Solutions
(SVS). The new Cat ® AD22 is derived from the
SVS UAT designs and is currently undergoing
field trials.
The new Cat R1700K underground LHD
features multiple engine configurations, a new
ergonomic operator cabin and greater payload.
The compact profile, efficient power train and
rugged construction deliver low cost truck
loading and LHD production.
