Wheel dia. calculation of bridge drive (Indoor EOC)

* Bridge drive(travelling) 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.)

* Bridge self weight : B=     ton

(girder & saddle(rocker) & bridge drive & acc.)

* Bridge span : S =     cm

* Hook(attachment) approach : Ab =     cm

(Bridge wheel & hook(attachment) distance)

* Bridge rail size : rail      kg/m

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

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

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

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

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

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

* Bridge wheel quantity : n =      ea

* Used wheel dia. : Du =      cm

 

* Bridge wheel load : Pmax, Pmin, Pmean

* Required wheel dia.

 

( Calculated value )

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