330D MH Material Handler

Special features provide for aggressive performance, reliability, and excellent productivity.

Fixed Riser

CAT® designed and built, 1.95 m (6'5") 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 to the platform extending around the cab riser. This platform allows 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 2.6 m (8'6") 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 grapple open-close function is provided on the right side joystick. The rotate function is also 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 entering the cooling system. The optional automatic reversing fan purges dirt and dust from the cooling system.

Generator Set

A 20 kW (26.8 hp) hydraulically driven generator set can power magnets up to 1.68 m (66") in diameter.

330D MH Two-Piece Caterpillar Front Linkage

Caterpillar 330D Material Handler fronts are purpose designed and built for excellent reach, flexibility, and lift performance to meet all requirements of material handling applications.

CAT® Two-Piece Front Linkage

Offers a maximum horizontal reach of 16 m (52'6") from swing center and maximum vertical reach of 16.9 m (55'5"). This front is an excellent match for the 0.96 m3 (1.25 yd3) grapple or a 1.68 m (66") magnet. An optional 14.6 m (47'1") two-piece front linkage has a maximum vertical height of 15.8 m (51'11"). This front is an excellent match for the 1.15 m3 (1.5 yd3) Orange Peel Grapple or the 1.68 m (66") Walker magnet.

Material Handling 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

Maximizes strength and minimizes structure weight.

Dual Stick Cylinders

Provides excellent geometry for working close in to the machine or at full reach.

Heavy Lift

Provides additional lift capacity for handling of heavy, robust objects.


ACERT™ Technology meets U.S. EPA Tier 3 emission regulations, with exceptional performance capabilities and proven reliability.


Six-cylinder, turbocharged engine built for power, reliability, and economy will allow the machine to consistently perform at high levels. The CAT® C9 engine is designed for low emissions and will meet EPA Tier 3 emissions requirements.


The 330D MH structural components are the backbone of the machine's durability and provide for excellent stability.

High and Square Undercarriage

Provides excellent over-the-side stability required to handle heavy loads and improve productivity. Provides excellent ground clearance required to clear obstacles.

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

A variety of grapples and magnets are available to maximize machine performance in material handling applications.

Walker Magnets

The Walker 1.68 m (66") Lift Master magnet can be used with the 330D 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 0.96 m3 (1.25 yd3) and the 1.15 m3 (1.5 yd3) Orange Peel Grapples are available 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.

Serviceability and Complete Customer Support

Simplified service and maintenance features save you time and money. Your CAT® dealer offers a wide range of services that can be set up under a customer support agreement when you purchase your equipment.

Ground Level Service

The design and layout of the 330D 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 maximum cleaning efficiency. When the air cleaner plugs, a warning is displayed on the monitor inside the cab.

Capsule Filter

The hydraulic return filter, a capsule filter, is situated outside the hydraulic tank. The 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 330D 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 330D 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 downtime. You can also save money with remanufactured components.

Machine Selection

Make detailed comparisons of the machines you are considering before you buy. What are the job requirements, machine attachments and operating hours? What production is needed? Your CAT® dealer can provide recommendations.

Customer Support Agreements

CAT® Dealers offer a variety of product support agreements, and work with customers to develop a plan that best meets specific needs. These plans can cover the entire machine, including attachments, to help protect the customer’s investment.
