Key Features

Commitment from the Ground Up


Recognizing that fuel efficiency is directly affected by hydraulic performance, the hydraulic system in the MH3049 is carefully designed to provide the work needed without wasting fuel. A high capacity hydraulic cooling system keeps operating temperatures low, resulting in longer component life, higher efficiency and lower repair cost.

Structural Integrity

You expect quality and durability. The MH3049 is purpose-built from the ground up with frame construction that utilizes continuous welds, extensive chamfering, “feathered” weld end points and radiused corners. Critical areas use high grade structural steel, and areas susceptible to side loading have pins oversized by 15%-20%, with threaded retention. To withstand extreme loads encountered in material handling applications, both the boom and the stick are built from single piece continuous top and side plates - no seams or baffles.

User-Friendly Technology

Effective operator and machine communication is critical in any job application to ensure productivity. The MH3049 features a user-friendly operating system that clearly communicates machine conditions in plain language, no need to research code definitions. In addition, the in-cab monitor reports machine conditions, warnings and maintenance checks. To increase comfort, operators can adjust machine functions, such as joystick control sensitivity through the operating system.

Lower Operating Cost

Low operating cost was one of the top priorities throughout the MH3049’s design phase. The combination of extending component life, optimizing fuel efficiency and an innovative hydraulic system all work together to provide the lowest possible operating cost.

Safety and Comfort

Decrease the risk for slips and falls with the patented “ground entry and exit” hydraulic cab riser system. This innovative system will lower the cab to ground level for operator entry and exit. This is one of many features the MH3049 brings to improve the safety of your operations.

Engine and Power Train

More Power and Efficiency

More power when you need it, the Cat C9 ACERT large displacement engine optimizes machine performance and enhances fuel efficiency while meeting Tier 3/Stage IIIA emission regulations. The C9 is an 8.8 L (537 in3), in-line 6 cylinder engine rated at 224 kW (300 hp). This market proven Cat engine produces enough power to run simultaneous machine operations.

Precise Engine Control

The ADEM™ A4 (Advanced Diesel Engine Management) provides quick response to engine demands. Utilizing flexible fuel mapping, the ADEM A4 electronically controlled fuel module monitors performance with sensors in the air intake, fuel, exhaust and cooling system to produce higher efficiency and lower emissions.

Enhanced Fuel Efficiency with Auto Throttle

Fuel can drastically affect your businesses’ operating cost. The fuel saving auto throttle feature reduces the engine rpm back to idle after five seconds of inactivity, decreasing fuel consumption.

Dependable Power Train

True all-wheel drive is achieved with four independent planetary wheel drives. Oscillating rear housing with lock-out feature and solid rubber tires provide machine stability and traction. As a result, there are no transfer cases, axles or drive shafts in the undercarriage from which material could drag and damage machinery.

Convenient Travel

Machine movement is regulated through a two mode shift on the fly travel system that includes a creeper mode up to 5.0 km/h (3.1 mph) and a standard mode up to 12.0 km/h (7.5 mph). Steering and speed are controlled through the joystick controls while forward and reverse direction is controlled through a foot pedal.

Hydraulic System

Effective Hydraulics - Improve Your Machine’s Performance

Machine productivity depends on hydraulic performance. The MH3049’s hydraulic system is designed to provide power without compromising efficiency, and protect component life to keep your machine running.

Torque Performance

Proper torque distribution on the MH3049 allows you to run simultaneous operations without compromising performance or efficiency. A dedicated closed loop swing system ensures that machine implement functions do not interfere with swing movements. A dual pump system produces hydraulic power for the implements, work tools, travel and cab riser systems. The engine flywheel evenly divides power between both main pumps through a two pad pump drive gearbox. A dedicated swing pump provides torque for swing functions, maintaining swing priority for increased production cycles.

Low Operating Temperatures

Running at lower operating temperatures protects component life. The MH3049’s hydraulic system is linked with its own independent cooling system to ensure that low operating temperatures are maintained. The independent hydraulic cooler features a variable speed auto-reversing hydraulic fan and its own air tunnel to ensure proper ventilation without compromising the engine’s cooling system.

Fast Cycle Times

Faster cycle times increase productivity. An efficient load sensing hydraulic system supplies quick lift and implement performance while providing control regardless of boom, stick or travel demands. The dedicated hydrostatic swing system ensures that swing speed is not affected by other machine functions.

Flow Management

Operating costs are cut with flow management technologies. Flow-sharing compensation delivers flow on-demand for smooth, efficient operations, regardless of load. Load sensing pumps generate only the flow and pressure required to meet system demands based on the work being done.

Structure and Frame

Built Quality - Structural Integrity

Your operators face harsh working environments that can affect the durability of your equipment. With this in mind, the MH3049 was built beyond industry standards. Structures were subjected to extensive strain gauge testing and finite element analysis to ensure built quality and durability. Not cutting any corners, structural grade steel is used in critical areas. Built to last, The MH3049 has continuous welds along with chamfering and feathering techniques. Pins and bushings are oversized to prevent stress failures and lubricated through the automatic lubrication system to enhance component durability.


The MH3049’s frame is divided into an upper and lower portion. The upper frame houses the hydraulic cab riser, counterweight, boom, engine and hydraulic system. The boom foot is mounted at the upper frame’s center to create a stable working platform. The upper frame attaches to the lower frame through the MH3049’s rotating axis, a 660 mm (26 in) fully boxed riser ring with 51 mm (2 in) integrated top plate. The lower frame is high off the ground to prevent any materials from dragging and the design is tapered to evenly distribute the weight on its four outriggers.


Weighing 9980 kg (22,000 lb), the cast counterweight, located at the rear of the machine, includes a grid enclosure to ensure ventilation of the engine and hydraulic machinery compartment. The rearview camera is housed in the counterweight, protecting it from debris.

The MH3049 is meant to be an integral part of your operations for many years to come, built strong with thick plates, radiused corners and detailed welds.

Front Linkage

Durability - Built with No Compromises

You know that a material handler works only as good as its front linkage is able to handle the job. The MH3049’s boom and stick are purpose built for the loads encountered in bulk material handling applications, able to withstand extreme loading conditions. Careful and detailed handling of stresses ensures that the MH3049 has the durability you need for your day-to-day operation. The boom and stick top and side plates are manufactured from single plates of steel to eliminate the need for internal baffles and cross boom weld joints. Feathered welds and strengthened connections compliment the structural integrity of the front linkage. Automatic lubrication on linkage pins and bushings extend component life, protecting your investment. Excellent lift performance is delivered with dual boom cylinders and stick cylinders. The boom foot mounted on the center of the upper frame creates a stable lifting platform. The 10.67 m (35'0") boom and 8 m (26'3") drop nose stick provide a horizontal reach of 17.8 m (58'5") and a large working envelope, minimizing machine travel and bringing down operation costs.

Falling and flying debris is one of the hazards of the workplace. To protect your operator, the MH3049 is equipped with the impact-absorbing cab guard that conforms to ISO 10262 safety standards. The Falling Object Guarding System consists of two parts that are bolted on top of the cab and on front of the windshield.

High Operator Visibility

The ability to see your work area is critical to a safe working environment. The cab is purposefully designed to provide high visibility and ensure that the operator can view his work area. The cab includes a polycarbonate skylight, removable window panes and a rear window that serves as an emergency exit. Joystick controls in lieu of a steering wheel provide a less obstructed front view. In addition, a cab mounted windshield wiper improves operator visibility in wet weather conditions.

Rearview Camera

Having line of sight to what is happening behind the machine is vital in maintaining a safe work environment, which is why a rearview camera is mounted on the counterweight. The live audio and video transmission is fed through the HD color monitor in the cab.

Safer Operations

Maintain safe working distances with the stick limiter, which prevents the work tool from coming into close proximity to the operator station. Function override controls allow for up close work. Operators will be warned through the cab monitor when the machine is nearing or exceeding lift capacity. If lift capacity is exceeded, boom and stick functions are limited as an added assurance to protect your investment from preventable accidents.

Ground Access Cab

You are safer from the risk of slips and falls with the MH3049’s patented ground entry and exit cab riser system. In the event of a power loss, a cab riser pressure release valve located in the operator station allows for the cab to be lowered, enabling the operator to safely exit the machine.
