Page 219: Lifting Capacity Of The Excavator
Lifting capacity of the excavator LIFTING CAPACITY OF THE EXCAVATOR Constructive calculation of lifting capacity The lifting capacity of the excavator is based on ISO 10567 and does not exceed 75 % of the static tipping load or 87 % of the hydraulic lifting capacity of the machine. The lifting capacity is measured at the front bolt of the arm with the arm fully extended.
Page 220: Lifting Attachment
Load suspensions (e.g. hooks) may only be welded on by suitably skilled personnel. For this type of work, please contact your KUBOTA dealer. At every point of the implement or the boom, the lifting attachment must withstand a load of two-and-a-half- times its rated lifting load.
Page 221: Load Suspension Device
Lifting capacity of the excavator Load suspension device A load suspension device with all the characteristics listed below is required: The system must withstand a load two-and-a-half times its rated lifting load, regardless of the point at which that load is applied. The system must be designed in such a way as to practically prevent any objects that have been lifted from falling from the lifting attachment, for example by means of a protective attachment designed for this purpose.
Page 222 Information on inspecting lifting equipment in France The test coefficients determined by KUBOTA and to be applied for the commissioning or recommissioning of ma- chines equipped for lifting (article 10 et 11 de l'arrêté du 1 mars 2004 relatif aux vérifications des appareils et ac- cessoires de levage) are 1.0 for static testing and 1.0 for dynamic testing.
