I needed some additional storage for my basement shop. Note in picture that planer, mortiser, mini-bandsaw, air compressor, and other tools are stored on the shelves. Also note roll around cart in front of shelf. My planer is very heavy, and since I have had some minor back issues, I’m always concerned when lifting the planer that I will cause a major back issue. Now I roll the cart upto the shelf, slide planer or mortiser off shelf and onto cart, do the job required, and slide them back onto storage shelf… easy peasy! Cart is not only same height as shelf, it’s also same height as table saw and various work tables in my shop. I can transport any heavy item around the shop while keeping it at the same height, just sliding it around. This has been a real back saver.
