Caterpillar says its new MH3037 wheeled materials handler has been built from the ground up for industrial, scrap recycling, millyard and waterway applications.

The Cat MH3037 is the first of a new material handler line-up Caterpillar is introducing in the greater than 25-metric ton size class.

The model is the first in a series of new wheeled handlers Caterpillar is introducing in the greater than 25-metric tonne size class.

The Cat MH3037 has an operating weight of 39,500kg and is powered by a Cat C7.1 ACERT engine that meets USA EPA Tier 4 Final/EU Stage IV emission standards.

The engine, which gives a rated output of 225hp, features an electronically controlled, mechanically actuated, unit-injector fuel system that uses multiple-injection fuel delivery for optimum power and economy in all operating conditions.


Cat says high-strength structural steel and advanced welding techniques have been used for the construction of the machine.

Booms and sticks are constructed from single-piece top and side plates to eliminate the need for seams and internal baffles.

The upper frame is designed specifically to dissipate loads transferred through the front linkage and counterweight, while the lower frame has a unique tapered design for evenly distributing loads and reducing stress.

In addition to the 8.8m boom, the MH3037 can be equipped with a shorter 5.8m version or a longer 7.2m front configuration to best fit application requirements.


The MH3037 uses a closed-centre, 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 hence helping operators save on operating costs.

To further enhance overall hydraulic power and efficiency, the machine regenerates boom-down oil flow, hence reducing the volume of oil the pump must produce.

The hydraulic oil cooler, engine air-to-air aftercooler and engine radiator are all mounted side-by-side to reduce clogging by airborne debris and to provide better access for cleaning.

The Cat MH3037’s powertrain incorporates limited-slip differentials on both the front and rear axles to provide true all-wheel drive performance.

A variable displacement hydraulic motor, coupled with a two-speed transmission provides high and low speed travel and creeper speed capabilities.


The hydraulic cab-riser system on the MH3037 allows cab height to be adjusted up to an eye level of 5.5m. In the event of engine power loss, manual override valves in the cab allow the cab to be lowered so the operator can exit safely at ground level.

The MH3037 can be equipped with an optional falling-objects guarding system (FOGS). This includes a top guard to protect the operator from falling debris and a front guard to prevent debris from flying into the work area.

A rear-view camera comes standard with the MH3037 which image is displayed on a high-definition color monitor. A separate monitor displays operating parameters, starting fluid levels and machine warnings.

Work functions and steering are all controlled with joysticks for a smoother and faster operation.


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

Greaseless bearings in the cab-riser linkage reduce maintenance and an upper auto-lube system lubricates critical areas based on runtime.


Cat’s Link and Detect technologies are available on the MH3037 to allow operators to wirelessly track machine location, hours, fuel consumption, idle time, events codes and diagnostic codes via the online VisionLink user interface.

Cat has designed the MH3037 to handle a variety of work tools including orange-peel grapples, clamshells, log grapples and more.
