<p>The present invention relates to a winding force measuring method of an elevator to measure the winding force when the number of people more than capacity is on board by using a static frictional coefficient by a rope pulley and a winding rope. The winding force measuring method of an elevator according to the present invention comprises: a step (ST100) of coupling with a rope catcher (30) to restrain elevation of a winding rope (20); a step (ST200) of measuring an unbalanced weight by detecting load applied to the winding rope (20) by a weight detector (21); a step of (ST300) of slipping the winding rope (20) from a rope pulley (16) by forcibly operating a winding means (13); a step (ST400) of calculating a maximum static frictional coefficient by the rope pulley (16) and the winding rope (20); and a step (ST500) of calculating maximum winding force by using the maximum static frictional coefficient.</p> |
