SLEWING RINGS - Rima (UK)

R E A D I N G O F T H E C H E C K C H A R THOW TO DETERMINE THE EQUIVALENT LOADS (Fa.eq, Mr.eq)• Peq = equivalent loads pointFa.eq = Fa + 5,05 . FrMr.eq = Mr.Significance:Fa = Nominal axial load (KN)Fr = Nominal radial load (KN)Fa.eq = Equivalent axial load (KN)Mr = Nominal tilting moment (KN.m)Mr.eq = equivalent tilting moment (KN.m)• Pu = point of useFa.u = Fa.eq . K.stat.Mr.u = Mr.eq . K.stat.Significance:K stat = Safety factorFa.u = Axial load of work (KN)Mr.u = Tilting moment of work (KN.m)Please note: the Pu must be under the curve of the limit load chartThe ratio OM/OPu represents the nominal safety factor that must correspond to the value and specificationsimposed by the user.The formulas for the preliminary choice of the slewing rings correspond to a hypothetical case with:• Axle of vertical rotation• Inferior speed to 1 turn / minute• Work without shock• Without considering the resultant loadof the gear• For different application please refer toour technical department.Please note: in all cases, the customerrequirements in this section must beconfirmed by our technical department.8
