* Braking torque calculation of hoisting device (Indoor EOC) * Hoisting motor power : Pu = kw x set * Hoisting motor rpm : N = rpm * Requird brake safety factor : Sf = (% of motor torque) * Used braking torque : Tu = kg.m/set x set * Required braking torque ( Calculated value ) * Required braking torque Tb = kg.m < Tu = kg.m/set x set
