Dump truck or duck truck?

Here's an interesting video of a Komatsu track off-road dump truck that has apparently been around a few years but we just learned of it.  Although the truck doesn't hold as large a load as a traditional wheeled dump truck, it will travel in water, snow and mud, and the truck bed swivels, helping the truck get into position with minimal maneuvering.  Half way in the video clip a smaller tracked dump is shown in action - demonstrating the utility of having a trackbed that can swivel and dump, i.e., acting as a side dump.
