Cat designed its new MH3250 and MH3620 tracked material handlers to reduce owning and operating costs by 20% from their predecessors, the company says.
Cat achieves the lower O&O costs by increasing fuel efficiency and maintenance intervals, among other improvements.
The models, which also come with a new cab concept, replace the 330D MH and 345 C MH. Lift height is 52.5 feet for the MH3250, and 59 feet 1 inch for the MH3260. Operating weight is 107,700 pounds for the MH3250, and 133,200 pounds for the MH3260.
Both machines have new Cat Tier 4 Final diesel engines that can run up to 20% biodiesel fuel. The MH3250 delivers 311 net horsepower and the MH3260 produces 424.
Three different power modes can match performance to the task:
For the operator, Cat recreated the cab, making it quieter with sound suppression. It sits upon rubber mounts to reduce vibration. It also features an air-suspension seat that is heated and ventilated. Keyless push start is also standard. Controls are in front of the operator within close reach. The left-hand console tilts up to make it easier to get in and out of the cab.
The 10-inch high-resolution touchscreen uses a jog dial-control. The screen also shows views from the standard side and rear cameras. Operators can set their joystick and power mode preferences with the Operator ID function, and those parameters will return automatically when the ID is typed in.
