Power, Reliability and Fuel Economy
The Power and Performance You NeedThe Cat engine meets China Nonroad III, UN/ECE R96 Stage IIIA emission standards, and U.S. EPA Tier 3/EU Stage IIIA equivalent emission standards, delivers a maximum net power (Acc. ISO 14396) of 128.8 kW at a rated speed of 2,000 rpm.
Fuel Efficiency – Common Rail Fuel System and Fuel PumpThis combination provides outstandingly low fuel consumption during both working and traveling applications.
Fuel Efficiency – Demand Fan Cooling SystemThe electronically controlled hydraulic motor drives a variable speed on-demand fan, resulting in optimized fuel consumption.
Fuel Efficiency – One-Touch Low Idle ControlThe Automatic Engine Speed Control reduces engine speed if no operation is performed, reducing fuel consumption and sound levels.
Fuel Efficiency – Eco and Work Modes
- The Eco Mode can significantly reduce your fuel consumption
- The Travel Mode optimizes driveline performance while preserving fuel
- The Power Mode is the best compromise between productivity and fuel efficiency
Fast, Precise, Flexible
Efficient Design, Smart and Fast
- Dedicated Swing Pump – A closed hydraulic circuit is dedicated to the swing only. Having two separate pumps, one for the swing and the other for the other functions allows faster and smoother combined movements.
- Stick Circuit – Increases efficiency and helps enhance controllability for higher productivity.
- Boom, Stick and Cab Riser Hydraulic Snubbers – help cushion shocks, reduce sound and increase cylinders life.
Control Like No Other
- Heavy Lift Mode – maximizes lifting performance by boosting the lifting capability by 7%.
- Adjustable Hydraulic Sensitivity – Allows you to adjust the aggressiveness of the machine according to the application.
- Tool Control System – enables you to select up to 10 preprogrammed hydraulic work tools from the monitor. Proportional two-way flow is ideal for rotating tools with joystick sliding switches for modulated tool control.
Structure – Elevated Cab and Frame
Strength, Flexibility, Mobility
High Visibility – 2400 mm Elevated Cab
The hydraulic cab riser is designed to be:
- Stable – Wide lift arms, deep box-sectioned design, strong top and bottom links and retractable hydraulic cylinders used to raise the cab for greater stability.
- Fast – Two heavy-duty hydraulic cylinders provide quick and controlled up and down travel.
- Comfortable – The parallelogram design of the linkage allows the cab to remain level at all ranges of motion.
- Cab movement is also slowed as it reaches the end of the riser stroke, with no sudden start/stop effect.
- Safe – The cab can be lowered using either a lever inside the cab or one on the frame at ground level in the event of a hydraulic malfunction.
Undercarriage OptionsEffective hydraulic line routing, transmission protection and heavy-duty axles make the Cat undercarriages perfect for material handler applications.
Three different undercarriages are available to provide the stability you need for your applications:
- Material Handling – The Material Handling undercarriage with four welded outriggers is ideal when extra stability is needed.
- Material Handling with Dozer Blade – An optional expansion to the Material Handling Undercarriage includes an additional dozer blade mounted ahead of the front stabilizers to be used to push material commonly encountered in waste and millyard applications.
- Standard – The Standard undercarriage is equipped with dozer blade at front and stabilizers at rear.
Heavy-Duty AxlesThe front axle offers wide oscillating and steering angles. The transmission is mounted directly on the rear axle for protection and optimum ground clearance.
Advanced Disc Brake SystemThe disc brake system acts directly on the hub instead of the drive shaft to avoid planetary gear backlash. This minimizes the rocking effect associated with working free on wheels.
Keeps Operators Productive All Shift Long
Legacy from the Renowned Cat Wheel Material HandlersDesigned for the operator, our cabs are unique.
- Frequently used switches are centralized, kept to the minimum and ideally located close to the joysticks.
- Storage compartments are useful … when well designed. The lunch box provides sufficient room to store a hard hat. Several other areas include drink, phone, or key holders.
Comfortable Seat OptionsOur seats provide all the comfort needed for a long day of work. The comfort seat is equipped with a passive seat climate control and air suspension which can be adjusted to the operator’s weight.
Automatic Climate ControlEasy adjustment of the cab temperature with filtered ventilation.

Standard Rearview CameraTogether with the best in class visibility to all sides, the rear view displayed on the monitor helps ensure a safe operation.
Large Color MonitorEasy to read and in local language, you can rely on the high resolution LCD monitor, which will keep you aware of any important information. “Quick Access” buttons allow a quick selection of favorite functions. The tool select function lets you preset up to ten different hydraulic attachments for quick tool changes.
Durability – Designed with No CompromisesYou know that a material handler works only as good as its front linkage is able to handle the job. The M322D2 MH’s booms and sticks are purpose built for the loads encountered in material handling applications. Sticks are purposely designed with leading side plates to maximize the protection of hydraulic lines.
MH BoomMH booms include high pressure hydraulic lines for opening and closing functionality and medium pressure lines for implement rotation.
MH SticksMH sticks are equipped with high and medium pressure auxiliary lines. The 4900 mm and 5900 mm Drop Nose Sticks offer the reaching and lifting capabilities required for typical MH applications, while the 4800 mm Straight Stick is the best solution when additional work tool functionality is needed.
Special ApplicationsThe M322D2 MH offers the ability to combine the hydraulic cab riser with a traditional excavator front linkage. This combination has been proven in transfer station, mining, and millyard applications.
When Operation Becomes as Easy as Pleasant
Joystick SteeringKeep both hands on your joysticks even when you need to reposition the machine while simultaneously moving the implements. You can do more precise work faster with increased safety around the machine.
Get the best power output from the engine and hydraulics and maintain optimum fuel efficiency:
- Economy Mode – for precise material handling and loading with the added benefit of reduced fuel consumption.
- Power Mode – for applications requiring fast volume loading and material casting.
Automatic Travel ModeAutomatically engaged when the travel pedal is depressed, this mode provides maximum speed, drawbar pull and best in class fuel efficiency.
SmartBoomAllow your operator to fully concentrate on production.The unique Cat SmartBoom significantly enhances operator comfort and job efficiency by reducing stress and vibrations transmitted to the machine. Loading is more productive and more fuel efficient as the return cycle is reduced while the boom down function does not require pump flow.
Your Safety is NOT Optional
Smart devices are embedded to offer as much safety as possible for your operators, and help enforce safe behavior:
- Large handrails and steps assist you during cab ingress and egress.
- Anti-skid plates on all walkways and steps reduce slipping hazards, by decreasing the accumulation of mud, improving machine cleanliness and operator and technician safety.
- LED rear lights enhance visibility.
- Seat belt.
- Emergency shut off switch and battery disconnect switch.
- Lowering check valves.
- Standard rearview camera gives you a clear field of view behind the machine through the monitor.
- MSS Machine Security System prevents unauthorized machine use.
