A close look at what happens when multiple ropes share traditional edge rollers.
Members: Rope efficiency in haul systems
Last month I published the test report: Pulley + rope efficiency. As with most tests, I was left with even more questions. The key observation was that measured pulley efficiency varies significantly (up to 10%)
Members: Pulley + rope efficiency
There more to measured pulley efficiency than just consideration of the physical bearings or bushings on the axle. This report considers the effect of losses within the rope.
Members: Transport Hitch
The Transport Hitch can be used to tension and hold a load in a limited set of scenarios. It is an interesting study of physics and it helps us to understand the importance of friction. This knot
