The new Cat MH3250 and MH3260 models deliver high efficiency in demanding material handling applications. Replacing the historical Cat 330D MH and 345 C MH models respectively, the next-generation MH3250 and MH3260 tracked material handlers boast longer maintenance intervals and improved fuel efficiency to decrease owning and operating costs up to 20%. An entirely new cab concept elevates operator comfort throughout the shift to increase productivity.
Both models feature new mechanical variable-gauge undercarriages that flexibly improve machine transportation without sacrificing lifting performance. Track gauge retracts to 10 feet, 7 inches to lower transport costs and make moving the material handlers more efficient. When at the yard, gauge extends to 12 feet, 2 inches wide to increase stability and maximize lift capacities. The MH3250 and MH3260 have respective 52 feet, 6 inch and 59 feet, 1 inch maximum reach, reducing the number of times the material handler has to be repositioned at the yard to increase productivity.
Three different power modes — Power, Smart and Eco — fine-tune power requirements to the job, so the new MH3250 and MH3260 use less fuel than their predecessors without sacrificing machine performance. Smart Mode automatically matches engine and hydraulic power to working conditions to reduce fuel consumption, while Power Mode provides maximum power to optimize productivity. The machines’ new fuel-efficient engines meet stringent U.S. EPA Tier 4 Final emission standards and can run up to B-20 biodiesel.
An upper-level service platform with access steps constructed of antiskid punch plate provides easy, safe, and quick access to machine service items. In the event of a hydraulic service interruption, the cab can be safely lowered via one of two emergency cab lowering valves, located inside the cab as well as outside of the machine. Check valves on the boom and stick prevent reverse hydraulic oil flow, to maintain the position of the front linkage should the hydraulic system experience an unexpected loss in pressure.
Synchronized service intervals and extended filter replacement schedules reduce maintenance time and costs for the new Cat MH3250 and MH3260 material handlers. All fuel filters feature a coordinated 1,000-operating-hour change interval, and the new air intake filter with precleaner lasts up to 1,000 hours to reduce maintenance requirements. A new hydraulic oil filter improves filtration and increases change intervals to 3,000 operating hours, a 50 percent longer service life than previous filter designs. New anti-drain valves keep the hydraulic oil clean during filter replacement to improve system longevity.
Operators conveniently track filter life and maintenance intervals on the in-cab high-resolution monitor. The high-efficiency cooling fan features an automatic reverse function to keep the cores clean, maximizing machine uptime. Conveniently located Cat S∙O∙SSM ports allow for quick fluid sample extraction for analysis, simplifying maintenance.
