Caterpillar wheeled material handlers updated for improved operations

The updated Cat® M325D MH and M325D LMH wheeled
material handlers are designed to meet the production
requirements in bulk materials handling applications and in the
scrap and recycling industries. The updated models feature a
new, optional cambered boom for superior reach into barges, a
new front linkage that allows the operator to fold the stick up
under the boom for easier transport, a reinforced cab structure
and refinements for enhanced safety, and a new, optional autoreversing
fan for reliable machine operation in dusty areas.
The M325D MH is equipped with four sets of dual 12.00-20
solid rubber tyres and has an operating weight of 30,871kg
(68,059 lb). The M325D LMH has an operating weight of
35,261kg (77,737 lb) and is equipped with four single 16.00-25
solid rubber tyres. Optional pneumatic tyres are available. The
reach of the two machines is in the 14.3 to 15.6-metre range (47
to 51 feet).
The Cat C7 Engine with ACERT® technology powers both
machines. The C7 produces net power of 140kW (190hp) and
features electronic controls that govern the mechanically
actuated unit fuel injection (MEUI) system. The ADEM™ A4
electronic control module manages fuel delivery to get the best
performance per unit of fuel used. The engine management
system provides flexible fuel mapping, allowing the engine to
respond quickly to varying application needs. Automatic engine
speed control offers two-stage one-touch control for maximum
fuel efficiency and reduced sound levels.
The hydraulic system is designed specifically to handle the
requirements of demanding material handling applications. The
D-Series models use a hydraulic cross sensing system that can
maximize hydraulic power when needed for faster implement
CAMBERED BOOM SPEEDS BARGE UNLOADING
The 9.9-meter (32.5-foot) cambered boom is an option designed
for barge unloading applications. The configuration provides
excellent reach to unload materials from all corners and sides of
barges. Welded box-section structures are designed with thick,
multi-plate fabrications in high stress areas, which allow
NEW FRONT LINKAGE EASES TRANSPORT
The new front linkage of the updated M325D material handlers
makes it possible to fold the stick up under the boom, which
allows the machine to be transported in most regions with any
available stick combination installed. The new design uses a
longer boom and shorter sticks to maintain the working range.
The redesigned boom has 20% less section height, which results
REINFORCED CAB ENHANCES SAFETY
The new, reinforced cab structure provides enhanced protection
for the machine operator. It is compliant with 2006/42/EC. The
new roof window is scratch resistant glass, and an additional steel
crossbar at the front, top of the cab helps protect the operator.
A rear-view camera sending images to a display inside the cab
further enhance safety. For operator comfort, each material
handler now can be equipped with a factory installed radio with
CD. The system is MP3 ready. A flip release panel provides antitheft
AUTO-REVERSING FAN HELPS KEEP MACHINE COOL
The new automatic reversing fan purges dirt, dust and airborne
debris from the cooling system. The system automatically
reverses the fan at preset intervals to expel debris from the
radiator and engine compartment. In conditions that vary a great
deal, the operator can manually reverse the fan at any time. The
fan is controlled by the engine electrical control module for
smooth and reliable operation.
In addition to the enhancements that are new worldwide, the
M325D MH and M325D LMH wheeled material handlers sold
everywhere now can be equipped with a generator. The 20kW
SSMC (solid state magnet control) generator provides superior
reliability as a result of its soft start system and overheating
protection. In addition, the SSMC generator provides
commonality in joystick button usage, improved clean magnet
drop due to software control, and duty cycle monitoring to
prevent generator and magnet damage. Other benefits of this
generator include lower maintenance costs and improved
serviceability.
