Caterpillar introduces fourth model in line of material handlers

Cat MH3027 is purpose-built to work ideally in solid waste and scrap recycling applications.

Peoria, Illinois-based Caterpillar has introduced its Cat MH3027, which is the fourth and smallest member of the new wheeled material handler line that the company has introduced in the greater-than-25-ton size class. The Cat MH3027 has an operating weight of 62,832 pounds and is powered by a Cat C7.1 ACERT engine that meets U.S. Environmental Protection Agency (EPA) Tier 4 Final/EU Stage IV emissions standards. With a swing radius that is 213 millimeters (8.3 inches) less than the previous model, Cat MH3037, the company says the Cat MH3027 delivers a strong performance in a smaller package.

The new Cat material handlers are purpose-built to work productively and reliably in solid waste and scrap recycling applications, the company says. The MH3027 is available in configurations for waste handling, featuring a straight stick, and for scrap handling, featuring a drop nose stick. A debris-resistant cooling package with a hydraulic, variable speed, auto reversing fan and plug-resistant coolers equips the machine for challenging conditions, the company states.

New with the MH3027 model is the option to select from two hydraulic cab riser options: the cab-to-platform configuration or the patented “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, Caterpillar explains. The hydraulic cab riser escalates the operator up to 18 feet for optimal job site visibility, according to the company. 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.

Operation of the emissions control system is transparent to the operator, with no downtime for particulate filter regeneration, the company says. The engine features an electronically controlled, mechanically actuated, unit-injector fuel system that uses multiple-injection fuel delivery for power and economy in all operating situations. The MH3027 configuration is rated at 173 horsepower.

Caterpillar says the intelligent, load-sensing hydraulic system delivers power when needed and reduces fuel burn. High-strength structural steel and advanced welding techniques ensure structural integrity. Maintenance is simplified, according to the company, with enhanced serviceability features, such as auto lube for the upper area of the machine and centralized manual lube for the lower.

Using a closed-center, one-pump, load-sensing implement hydraulic system with electrohydraulic pilot control, the hydraulic pump generates only as much oil flow and pressure as required for the application, aiding with fuel efficiency, the company notes. To further enhance overall hydraulic power and efficiency, the machine regenerates boom-down oil flow, reducing the volume of oil the pump must produce.

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. The rear axle is equipped with an oscillation lock that provides greater stability during light-duty material handling without stabilizers deployed.

Durable fiberglass gull-wing panels supported by gas-filled cylinders provide ready access to the routine maintenance points in lighted compartments. Service panels are located on the top, left and right side of the machine.

Cat Connect offers Link and Detect technologies for the MH3027. Product Link™ helps fleet owners track locations, hours, fuel consumption, idle time, events and diagnostic codes by wirelessly reporting all via the online VisionLink® user interface to help lower owning and operating costs.

The MH3027 can handle a variety of work tools. The machine features medium-pressure flow from a separate valve for tool rotation and a high-pressure circuit from the main pump to operate the open/close functions of typical tools, such as orange-peel grapples, clamshells and log grapples.

A separate pump is used to provide hydraulic power to operate a generator for an optional scrap magnet. The generator features a patented Cat solid-state magnet controller that has a sorting feature to aid the operator.
