About 10 years ago I was on a project that installed quite a large telescoping shiploader. That had a 60" wide troughing conveyor that could telescope like in the video. I believe the belt was driven by a 600 HP 2400v motor. That was one difficult sumbitch to commission. The shiploader had 7 pulleys, all of which had to be aligned just right to maintain belt tracking. The problem is you don't know which pulley is tugging the belt out of position, and that changes depending on whether the conveyor is retracted or extended. It was a nightmare.
Anyway I respect the conveyors in this video. They are a lot more complicated than it looks.
