Key Specs
The Cat® MH3040 material handler builds upon the legacy of the M325D L MH to provide the power and reliability you need for your toughest material handling applications. A new cab along with up to 25% reduced fuel costs and up to 20% reduced maintenance costs combine with proven components to bring you the next generation of Cat Material Handlers.
The MH3040 is built from proven components designed to withstand the toughest applications. Count on the MH3040 to provide the durability and reliability you expect from Cat products.
Two power modes and a new electrically driven fan with auto reverse function minimize fuel use and increase engine efficiency.
With extended maintenance intervals and fewer connections and hoses, you get more done at a lower cost compared to the previous model.
