Hello,

this is a truck that can lift, carry and put down a container using two hydraulically operated arms. Today, I've seen such a truck on my way to work and remembered that I didn't build one in Minecraft yet.
This truck is quite versatile because it can carry many different types of containers for different purposes. Some examples are a press container for paper and packages or a salt spreading container for keeping the roads safe during winter.
If you search for these trucks probably search for "Absetzkipper". It's their German name and the results are closer to the truck I built than the results for "Swing Arm Garbage Truck".

Enjoy!
