Wheel dia. calculation of trolley drive (Indoor EOC)

* Wheel dia. calculation of trolley drive (Indoor EOC)

 

* Trolley drive(traversing) speed : V = m/min

* Rated load : R = ton

* Hook(attachment) weight : A = ton

* Trolley self weight : T = ton

(trolley frame & trolley drive & hoisting device & acc.)

* Trolley wheel base : Wb = cm

* Hook(attachment) approach : At = cm

(Trolley wheel & hook(attachment) distance)

* Trolley rail size : rail kg/m

* Trolley rail head breadth(dimension) : b = cm

* Trolley rail head corner radius(dimension) : r = cm

* Rail limiting pressure : K = kg/cm2 (refer to material)

* Trolley speed coefficient : C1 = (Refer to speed V)

* Trolley speed coefficient : C2 = (Refer to speed V)

* Trolley wheel material (KS,JIS,ASTM) :

* Trolley wheel quantity : n = ea

* Used wheel dia. : Du = cm

 

* Trolley wheel load :  Pmax, Pmin, Pmean

 

* Required wheel dia.

 

 

( Calculated value )

 

* Required wheel dia. Dr =      cm < Du =     cm
