CAT MH3027 Material Handler

The Cat MH3027 is the fourth and smallest in the series of new wheeled material handlers that Caterpillar is introducing to global markets in the greater than 25-metric-ton size class. At 28 500 kg (62,832 lb), the MH3027 delivers performance in a smaller package—specifically a swing radius that is 213 mm (8.3 inches) less than the Cat MH3037.

The new Cat material handlers are purpose-built and available a straight or drop nose stick. The Cat cab avoidance system, using sensors on the front linkage, is standard equipment and helps ensure that the work tool will not contact the cab. You can choose the cab-to-platform configuration or the “ground level entry and exit” with a step-in cab that lowers to the front or the side of the machine to enhance convenience and safety for operators and service personnel.

The hydraulic cab riser takes the operator to 18’0” feet for optimal jobsite visibility.  Additionally, the cab features joystick steering control, which eliminates the steering wheel and opens the front view for the operator. A standard rearview camera also expands sight lines with optional side view camera. It is powered by a Cat C7.1 ACERT engine that meets US EPA Tier 4 Final/EU Stage IV emissions standards.

Operation of the emissions control system is completely transparent to the operator—with no downtime for particulate filter regeneration. The engine features an electronically controlled, mechanically actuated, unit-injector fuel system that uses multiple-injection fuel delivery for optimum power and economy in all operating situations. The MH3027 configuration is rated at 129 kW (173 hp). The load-sensing hydraulic system delivers power when needed and reduces fuel burn. Using a closed-center, one-pump, load-sensing implement hydraulic system with electro-hydraulic pilot control, the hydraulic pump generates only as much oil flow and pressure as required for the application, yielding powerful, rapid response and fuel-saving efficiency.

The machine regenerates boom-down oil flow, reducing the volume of oil the pump must produce. True four wheel mechanical drive provides excellent maneuvering performance even on unimproved terrain. A variable displacement hydraulic motor coupled with a two-speed transmission provides high- and low-speed travel with creeper speed capability for control due to the infinitely variable travel speed.

An oscillating rear axle provides smooth travel over rough terrain.  The rear axle is equipped with an oscillation lock that provides greater stability during light duty material handling without stabilizers deployed. Fiberglass gull-wing panels supported by gas-filled cylinders provide ready access to the routine maintenance points in spacious, lighted compartments. Service panels are located on the top, left and right side of the machine. Handrails and anti-slip surfaces help technicians perform their work safely and efficiently.
