A new tool has been added to the tools page : WinchTools. WinchTools is a simply software which calculates some useful date about winch and pulley system. The aim is to calculate the maximun load on the hook with the parameters of your construction, including : motors, gears, diameter of winch, pulley system, weight of hook… Efficiency of drivetrain is managed, the available torque is reduced when you use worm and knob gear (lost power). I hope this software will be helpful for the crane builders to calculate speed, load, torque and so on. Winchtools by nico71 – Current version...
My version of LPE3i based on scotch yoke system (original ideas from LPEpower) but with new switches ! It works smoothly at 200RPM with 4 hand-pumps and without friction (thanks to the scotch yoke).
