This rock drill is similar to an Ingersoll Rand ECM-350, and has a ton of moving delicate parts. The boom will raise and lower, swing to the right and swivel. There are a lot of pins, which I'd strongly suggest you replace with metal, styrene rod or similar material. There is also a wheeled air compressor trailer that can be used with this piece if you so desire. Should there be any qeustions or issues, contact me via the designer link or via email to firstname.lastname@example.org
