For Release in North America: April 2013

With an operating weight of 111,000 pounds (50,349 kg), the MH3049 is the first of several new wheeled material handlers that Caterpillar will introduce in the greater-than-25-tons class. Coming immediately behind the MH3049 is the new MH3059 at an operating weight of 130,000 pounds (58,967 kg). The new Cat material handlers are purpose-built to work productively and durably in industrial, scrap recycling, and waterway applications, while affording maximum protection and convenience for the operator.

Both of the new material handlers are powered by the Cat ACERT C9 8.8L engine featuring 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 MH3049's C9 engine is rated at 300-horsepower (224 kW) while the MH3059 engine is rated at 325 hp (242 kW).

The hydraulic cab-riser system features patented "ground entry and exit" with a step-in cab, enhancing safety for operators and service personnel. Cab height on both machines is adjustable up to an eye level of 18.75 feet (5.70 m) on the MH3049 and 23.5 feet (7.2 m) on the MH3059. On the MH3049, raise time from ground level to maximum height is approximately 14 seconds; lowering time from maximum height to ground level is 12 seconds. Similarly, the raise time from ground level to maximum height on the MH3059 is approximately 17 seconds and lowering time from maximum height to ground level is 13 seconds. Adjustable sensors control the height of the cab above the ground. A manual safety override in the cab allows the operator to lower the riser in the event of engine power loss.
