WebFeb 25, 2024 · Abstract. The reeving efficiency is a measure of how effectively the drill line and sheaves transfer the drawworks power to the moving external load. The drill line is a steel wire rope having an inherent bending resistance. The internal bending friction is the dominating component of the single sheave efficiency, which is a function of line to … WebMar 6, 2024 · In a typical reeving system set-up, a motor actuates a sheave or reel from which a wire rope is directed via deviation sheaves to the payload. The seemingly simple set-up of reeving systems comprises a number of details that make dynamic modeling of such systems a challenge [ 1, 2 ].
WebMay 20, 2024 · The reeving system evolved from the block-and-tackle developed centuries ago, the mechanical advantage to lift a load—learned perhaps by trial and error of throwing a couple of vines over a tree limb and pulling down. This method’s modern components are drums, wire rope, sheaves, blocks, and end fittings (in other words, the reeving system). WebThe formula for finding the size of wire rope required to lift a given load is: C (in inches) = 2.5 x P (tons). You work this formula in the same manner explained above for fiber line.
