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.

Your operators face harsh working environments that can affect the durability of your equipment. With this in mind, the MH3059 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 MH3059 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.

Frame

The MH3059's frame is divided into an upper and lower portion. The upper frame houses the hydraulic cab riser, counterweight, boom, engine and a portion of the 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 MH3059'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.

Counterweight

Weighing 12 247 kg (27,000 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 MH3059 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.

You know that a material handler works only as good as its front linkage is able to handle the job. The MH3059'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 MH3059 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 complement 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.
