Motor power calculation of hoisting device (Indoor EOC)

* Motor power calculation of hoisting device (Indoor EOC)

 

* Hoisting speed : V = m/min

* Rated load : R = ton

* Hook(attachment) weight : A = ton

* No. of wire rope fall : N = fall

* Wire rope reeving efficiency : Er = (Refer to N & sheave bearing)

* Wire drum efficiency : Ed = (Refer to wire drum bearing)

* Gear reducer efficiency : Eg = (Refer to gear reducer stage no.)

* Used motor power : Pu =    kw x   set

 

* Required motor power

 

 

 

 

( Calculated value )

* Required motor power Pm =      kw x    set  <  Pu =      kw x    set
