WebJan 19, 2024 · So, the chain tension exerted by a 52-tooth chainring at 260 watts of power output and 126 RPM cadence is (176 N)/(4.45 N/lbf) = 40 lbf. And since 52 = 2 x 26, the … WebJan 20, 2024 · The G70 designation signifies that a tow chain’s tensile strength is rated at 70. A tow chain may be marked with a 7, 70, or even 700 to signify the G70 grade. With that out of the way, let us talk tensile strength for any of our readers who might not understand what that means.

One of the safety measures implemented was to place chain in Gradesbased on the ultimate breaking strength of that chain. This number is what we see today G30, G43, G70, G80 & G100 and the common chain grades. The number after each letter is N/mm2. For example, G80 means that the maximum stress … See more The other safety measure was identifying which types of chain are appropriate and strong enough for overhead lifting. Anytime we move or lift a load it is dangerous. Moving a … See more Alloy Chain Grade 80or Grade 100 should be used for overhead lifting.
