GeneMpls, It's a home made backhoe. Backhoe fits inside extension forks to get extra height for the scaffolding. It's faster and a whole lot easier for a 1 man operation than lugging around traditional scaffolding. Load all the heavy stuff on the platform and raise it up.
This set up gets the platform 6' off the ground
With the backhoe and extension forks the platform will go up 12'. That covers 99% of the work I do.
It's all built to fit on the trailer for easy access.
