Overview

Customization to Work for Your Application.

Caterpillar offers partial machines and systems in collaboration with Cat® dealers and Original Equipment Manufacturers (OEMs), providing specialty machines tailored to specific applications. Bare chassis trucks can be ordered with or without hoist cylinders, and most product options are the same as those available on dump truck models.

These models feature a higher Tractor ROPS certification for specialty applications, including water trucks, tow trucks, and fuel/lube trucks. Partial machine configurations are commonly used in construction, demolition, waste, material handling, and mining industries. These bare chassis options make it easier to purchase complete solutions through your Cat dealer, along with additional service and support.
