BENEFITS & FEATURES
M322C Material Handler
Increased lifting capacity, improved cycle times and ease of operation lead to increased productivity and lower operating costs. For additional machine information, consult the M322C specalog.


Material Handling Undercarriage
The MH undercarriage provides maximum durability and long life. A totally welded design, this undercarriage provides the stability needed for material handling applications and is especially well suited for machines with a hydraulic cab riser. The swing bearing is mounted directly in the center of the undercarriage to optimize lifting and reach in all directions. The four outriggers offer large cylinders, optimized kinematics and increased speed. They provide a wider stance than standard M322C outriggers for added stability and lift capacity. Hydraulic lines are routed through the frame. Cylinders have heavy duty guards to provide protection from damage.

MH Boom and Sticks
The M322C MH boom (6.8 m/22'4") has been redesigned to handle increased lifting capacities. The new stick range offers leading side plates to maximize protection of hydraulic lines. The lines are fitted between the two side plates at the stick nose, offering protection from damage. Three sticks are available.

Drop Nose Stick
The drop nose stick (4.9 m/16'1") offers reach and lifting required for typical MH applications. The stick contains high pressure and medium pressure hydraulic lines.

Long Drop Nose Stick
The long drop nose stick (5.9 m/19'4") offers a solution when maximum reach is required. The stick contains high pressure and medium pressure hydraulic lines.

Straight Stick
The straight stick (4.8 m/15'9") offers a solution for MH applications requiring an additional hydraulic function such as a sorting grapple. The stick contains high pressure and medium pressure lines and can be ordered with M318C bucket linkage to offer forward and back motion of the work tool.

Standard Booms and Sticks
A variable adjustable boom and curved one-piece boom are also available for the M322C MH with the standard stick options.

Fixed Cab Riser
The fixed cab riser offers a very stable and comfortable method to raise the cab. The fixed cab riser lifts the cab by 1200 mm (3'11") to offer better viewing to all sides. Well-positioned steps lead continuously from ground level to the raised cab. In shipping position, the cab is unmounted to meet national road regulations.

Hydraulic Cab Riser
The hydraulic cab riser design provides the most suitable solution when high flexibility in cab height is needed. The lift arms on the hydraulic cab riser are box-section designed for greater cab stability. Two heavy-duty hydraulic cylinders provide quick and controlled up and down travel. With the cab in the topmost position, the cylinders are retracted to ensure excellent stability. In the event of a hydraulic malfunction, the cab can be lowered using either a lever inside the cab or one on the frame at ground level. The linkage is a parallelogram design which keeps the cab level in all positions.

Top Position
The top position raises the cab by 2400 mm (7'11"). This provides optimal viewing to all sides in different applications such as scrap handling, log handling and various load/unload tasks. The cab's position is infinitely variable.

Medium Position
The medium position places the cab forward by 500 mm (20") more than in the travel position for increased visibility.

Bottom Position
The bottom position is used for shipping and travel position. When equipped with a VA boom or one-piece boom, this is the only position allowed for traveling on public roads.

Elevated Cab
Fixed and hydraulic cab risers are available to maximize viewing to all sides of the machine.

Dedicated Swing Pump
A separate dedicated variable displacement piston pump and fixed displacement piston motor power the swing mechanism. This closed hydraulic circuit helps to provide maximum swing performance without reducing power to the main hydraulic functions.

Caterpillar XT-6™ ES Hoses
To meet critical flexibility and strength demands of wheel excavator applications, XT-6 ES hoses and O-ring face seal couplings are installed for reliable, leak free connections. Hose routings are designed to protect from damage, reducing hose failure downtime.

Auxiliary Hydraulic Valves
The versatility of the hydraulic system can be expanded with multiple valve options.

Multi-function Valve
The multi-function valve is the core of the innovative Tool Control system. This valve can be electronically programmed for flow direction (one or two ways), pressure and flow rate. The valve also features priority flow to maximize control of the work tool. This on-board electro-hydraulic functionality eliminates the need for manual readjustments to the auxiliary hydraulics each time a different tool is used.

Medium Pressure
A medium pressure valve is available for use with standard medium pressure tools.

Hydraulic Cylinder Snubbers
The hydraulic cylinder snubbers at rod end of boom cylinders, both ends of stick cylinders and bucket cylinder rod end cushion shocks, reduce sound and increase cylinder life.

Boom Damping
Boom damping on the MH boom provides increased stability and reduced cab vibration. This contributes to precise machine controllability.

Stick Regeneration Circuit
The stick regeneration circuit increases efficiency and reduces cycle times.

Serviceability
Extended service intervals and easy access reduce operating costs.


Extended Service Intervals
Using Scheduled Oil Sampling (S•O•SSM), hydraulic oil change intervals can be extended from 2000 hours to 4000 hours. Engine coolant change intervals are up to 6000 hours with Cat Extended Life Coolant/Anti-freeze. Engine oil change interval is increased to 500 hours.

Easy Access
Gull-wing doors, with pneumatically-assisted lift cylinders, effortlessly lift up for exceptional access to the engine and all service points.

Easy to Clean Coolers
Flat fins on all coolers reduce clogging and make it easier to remove debris.
