* 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
