Benefits & Features
325D MH Material Handler
Fixed Cab Riser
CAT® designed and built, 6'5" (1.95 m) manual tilt cab riser provides for operating height with excellent visibility for loading and unloading processing equipment, trucks, and rail cars. Access to the cab is provided by a ladder leading up to the platform extending around the cab riser. This platform will allow for windshield cleaning. The cab riser can be manually tilted forward 90 degrees for shipping.
Hydraulic Cab Riser
Optional hydraulic cab riser provides up to 8'6" (2.6 m) of additional operating height. There is easy access to the cab platform provided by handrails attached to the riser.
Operator Controls
The ability to modulate the grapple open-close function is also provided on the right side joystick. The rotate function is modulated by using a slider switch mounted on the joystick.
Cooling System
External debris filters allow easy access for cleaning. This prevents clogging from dirt and dust coming into the cooling system. The optional automatic reversing fan purges dirt and dust from cooling system.
Generator Set
An optional 20 kW generator set can power magnets up to 66" (1.68 m) in diameter.
325D MH Two-Piece Caterpillar Front Linkage
The CAT® Two-Piece Front Linkage
Offers a maximum horizontal reach of 50'11" (15.5 m) from swing center and maximum vertical height of 53'11" (16.4 m). It is an excellent match for a 0.75 yd3 (0.57 cubic meter) Orange Peel Grapple or a 57" (1.45 m) Walker Magnet. The optional 46'4" (14.1 m) two-piece front linkage has a maximum vertical height of 49'11" (15.2 m) and is an excellent match for a 1.25 yd3 (0.96 cubic meter) Orange Peel Grapple or the 66" (1.68 m) Walker magnet.
Booms and Sticks
Designed and built for performance and long service life.
Welded Box-Section Structures
Efficiently designed with thick, multi-plate fabrications in high stress areas, which allows structures to flex, dissipating stress and maximizing strength.
Stress Relieving Booms and Sticks
Maximize strength and minimizes structure weight.
Dual Stick Cylinders
Provides excellent geometry for working close to the machine or at full reach.
Heavy Lift
Provides additional lifting capacity for handling of heavy, robust objects.
Engine
Cat® C7 ACERT™
The Cat® C7 with ACERT™ Technology introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology. The building blocks of ACERT™ Technology are fuel delivery, air management, and electronic control. ACERT™ Technology optimizes engine performance while meeting U.S. EPA Tier 3 engine emissions regulations.
Performance
The 325D MH, equipped with the C7 engine with ACERT™ Technology, provides 12% more horsepower as compared to the 3126B ATAAC HEUI in the 325C MH.
Automatic Engine Control Speed Control
The two-stage, one-touch control maximizes fuel efficiency and reduces sound levels.
ADEM™ A4 Engine Controller
ADEM™ A4 electronic control module manages fuel delivery to get best performance per gallon of fuel used. The engine management system provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It tracks engine and machine conditions while keeping the engine operating at peak efficiency.
Electronic Control Module
The Electronic Control Module (ECM) works as the "brain" of the engine's control system, responding quickly to operating variables to maximum engine efficiency. Fully integrated with sensors in the engine's fuel, air, coolant, and exhaust systems, the ECM stores and relays information on conditions such as rpm, fuel consumption, and diagnostic information.
Fuel Delivery
The Cat® C7 features electronic controls that govern the fuel injection system. Multiple injection fuel delivery involves a high degree of precision.
Air Cleaner
The radial seal air filter features a double-layered filter core for more efficient filtration and is located in a compartment behind the cab. A warning is displayed on the monitor when dust accumulates above the preset level.
Noise Reduction Technologies
The engine mounts are rubber-isolating mounts matched with the engine package. Further noise reduction has been achieved through design changes to the isolated top cover, oil pan, multiple injection strategy, insulated timing cover, sculpted crankcase and gear train refinements.
Structures
High, Square Undercarriage
Provides excellent over-the-side stability required to handle heavy loads and improve productivity. Excellent ground clearance provided to clear obstacles. Longer track roller frames increase over-the-front stability. Stands up in the toughest applications. Modified X-shaped, box section carbody provides excellent resistance to torsional bending. Upper structure weight and stresses are distributed evenly across the full length of the roller track frame.
Heavy Duty Upper Frame
The upper frame is specifically designed for the scrap and material handling applications. It is built of higher strength material and thicker steel sections to handle increased swing loads from the longer front and heavier counterweights used in material handling.
Work Tools - Attachments
Work Tool Selection
When choosing a work tool, please consider the work tool application, the variation of the density of material to be handled and productivity requirements. Check with your CAT® dealer for more details on specifications, sizes, and other work tool types.
Walker Magnets
The Walker 57" (1.45 m) or 66" (1.68 m) Lift Master magnets can be used with the 325D MH. These magnets have been designed and engineered for scrap processing applications. Ask your dealer salesperson for information on the Walker Magnet.
Orange Peel Grapples
The 0.75 yd3 (0.57 cubic meter) and the 1.25 yd3 (0.96 cubic meter) Orange Peel Grapples are available attachments.
Serviceability and Complete Customer Support
Ground Level Service
The design and layout of the 325D MH was made with the service technician in mind. Many service locations are easily accessible at ground level allowing critical maintenance to get done quickly and efficiently.
Pump Compartment
A service door on the right side of the upper structure allows ground-level access to the pump and pilot filter.
Radiator Compartment
The left rear service door allows easy access to the engine radiator, oil cooler and air-to-air-after-cooler. A reserve tank and drain cock are attached to the radiator for simplified maintenance.
Air Filter Compartment
The air filter features a double-element construction for superior cleaning efficiency. When the air cleaner plugs, a warning is displayed on the monitor screen inside the cab.
Capsule Filter
The hydraulic return filter, a capsule filter, is situated outside the hydraulic tank. This filter prevents contaminants from entering the system when hydraulic oil is changed and keeps the operation clean.
Fan Guard
Engine radiator fan is completely enclosed by fine wire mesh, reducing the risk of an accident.
Diagnostic and Monitoring
The 325D MH is equipped with S•O•SSM sampling ports and hydraulic test ports for the hydraulic system, engine oil, and for coolant. A test connection for the CAT® Electronic Technician (CAT® ET) service tool is located in the cab.
Extended Service Interval
The 325D MH service and maintenance intervals have been extended to reduce machine service time and increase machine availability
CAT® Dealer Maintenance
Choose from your CAT® Dealer's wide range of maintenance services at the time you purchase your machine. Preventive Maintenance will help you to avoid unscheduled repairs and diagnostic programs such as Scheduled Oil Sampling and Technical Analysis are available.
Product Support
You will find nearly all parts at our dealer parts counter. CAT® dealers utilize a worldwide computer network to find in-stock parts to minimize machine down time. Save money with remanufactured components.
Machine Selection
