Benefits & Features
M322C Material Handler
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.

Engine
3056E ATAAC Engine
The Caterpillar 3056E ATAAC turbocharged engine is built for power and meets all current worldwide emissions standards. The air-to-air aftercooler reduces smoke and emissions by providing a cooler inlet air for more efficient combustion. This also extends the life of the piston rings and cylinder bores.
Service
The engine is longitudinally mounted on the right side for easier servicing of the oil filter, oil filler, oil drain valve, fuel filter, V-belt tightener and the oil dipstick. All are accessible from ground level. The radiator and hydraulic oil cooler fan and air conditioner condenser are hinged for easier cleaning.
Cooling System
The cooling system features an electronically controlled variable speed on-demand fan. The fan is driven by a hydraulic pump. Fan speed is determined by engine coolant, transmission oil, hydraulic oil and inlet manifold temperatures. Cooler operating conditions allow lower average fan speeds resulting in reduced fuel consumption and lower noise levels. The electronic engine control continuously compensates for this varying fan load providing consistent net horsepower, regardless of operating conditions.

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
