I appreciate all the comments on my "How to pump concrete" video. Everyone seems to realize that this was just a BASIC introduction video. I would love to do some more in-depth videos focusing on safety, setup, on-site conditions and variables, and even as far as going into basic problem solving during a pour such as rock packing, sand packing, and even actual pump problems like E-stop malfucnctions, and hydraulic issues. I've seen a lot of various problems in my 2 years as a n operator/mechanic, and I feel I could help you guys understand a lot more about how to fix problems on tthe job when there is noone there to help you out. Still, I know there are guys on here that have years more experience than me, so feel free to keep giving out ideas on future video concepts. Thanks again for all the great comments, keep 'em coming.
