Good questions. Like all designs, tracks have trade offs. Turning is not the strongest part of track designs. However, the design of the treads profile has a lot to do with how the tracks perform in different situations. The taper on the side of the tread profile helps a lot with turning.
Roller chain is defined by ANSI standards. The working load for ANSI #35 roller chain is 480 pounds and the minimum tensile strength is 1760 pounds. Each section of track has two sets of chain on them. These are for standard chain and we obviously are using a modified version. But these are the most applicable numbers I have. We have not done any failure testing yet (it is on the long list). But I designed this to be a serious product and not a toy. Having a steel chain on booth sides of the track and two steel pins running through each tread mean these things take a lot to break.
