Lifting capacity of the excavator
Lifting attachment

The lifting operation is only permitted when the excavator is equipped with the following safety systems as
per EN 474-5:
– Pipe safety valve on the boom cylinder (page 189)
– Pipe safety valve on the arm cylinder (page 189)
– Overload warning system (page 190)

If the dozer is being used to increase the machine’s stability, an additional pipe safety valve must be installed
in accordance with EN 474-1 (page 189).

The lifting attachment is to be fastened to the attachment or to other parts of the excavator in such a manner
as to exclude the possibility of the lifting rope accidentally unhooking.

The installation on the attachment or the equipment must be such as to guarantee the optimum field of vision
between the operator and the guide [the person who fastens the lifting rope to the lifting attachment].

The lifting attachment is to be positioned so that the lifting rope is not deflected from its vertical direction of
tension by other parts of the machine.

The lifting attachment must be formed and positioned in such a manner as to exclude the possibility of the
lifting rope accidentally slipping.

Care must be taken when positioning the lifting attachment that there is no risk of restriction (e.g. becoming
caught on something) during normal operation of the excavator or when working on any particular object.

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.
