Material Handlers

Whether you operate indoors in areas with limited space such as a transfer or recycling station, or outdoors in a scrap yard or waterway/port application, material handlers are purpose-designed and built for excellent reach, flexibility and lift performance to meet the tough requirements of material handling applications. Special features such as heavy-duty frames and wide undercarriage ensure aggressive performance, reliability and excellent productivity. A variety of Cat grapples are also available to maximize machine performance in material handling applications.

Ultra High Demolition

UHD machines can reach higher and are capable of supporting the work tools you need for your demo job. Fronts can be interchangeable, making your demo jobs safer and faster. Caterpillar offers best-in-class work tools for bigger and more versatile demolition applications.

Long Reach

Long Reach excavators provide extra reach needed for deep digging applications, finishing/grading of embankments, and for dredging under water.

Rippers

Rippers are typically large hydraulic excavators equipped with short, heavy-duty booms and sticks. The stick is typically equipped with a ripper shank work tool. These machines are often used for ripping rock or tightly packed soil and can be found, for example, in road-building applications.

VA Booms

Variable Adjustable (VA) boom configured machines offer improved right-side visibility, better roading balance, improved versatility when working in tight quarters, and are able to lift heavy loads. VA-style booms offer improved flexibility and versatility versus a standard one-piece boom.

Extending Booms & Sticks

Extending booms provide extra-long reach in unique applications, such as working alongside of a pier or access to a subway shaft. Oftentimes the work tools used in such applications develop a square hole. Typical work tool for this application is a clamshell-style bucket.
