I don't speak Russian so I can't tell you what this guy is saying but if you watch the video you'll get the gist of his clever jig for boarding a ceiling without a helper...It consists of a platform with some vertical posts (2-by or whatever size they'd be in Russia) that support one end of the drywall. He lifts the piece onto the posts, steps up on the platform, and lifts the back end of the board to the ceiling.
The lighting is poor, but if you skip to the 1:14 point of the video you can see him pivot a second set of arms into the vertical position so they hold the drywall in place. If you don't feel like watching him fasten the board – you can skip to the 3:24 point for a good shot of how the pivots works.
It's not high-tech, but it beats the heck out of making T-shaped braces out of 2x4s and using them to wedge the board against the ceiling. And it's cheaper than buying a factory-made lift.
So what is this tool and why is it such a big deal? It's a Fluorescent Lighting Tester (2210-20) that allows an electrician or maintenance person to use a single detection device to figure out why a particular fixture or bulb isn't working - without ever leaving the ground. That may not mean much to those of us who have a few fluorescent fixtures in the shop or kitchen – but it does to the facilities guy who is responsible for the lights in an office building or school. If the building is large enough, he and a helper could work full-time changing bulbs and ballasts and never complete the job.
