d) tipping lines as shown in Figure 1;
e) at maximum reach with/without telescopic arm to the front/rear, as shown in Figure 2 and to the side as
shown in Figure 3.
5.8.4.2 Bucket application
The rated lift capacity for a walking excavator used in bucket applications shall be determined either by:
rated tipping load according to !ISO 10567:2007, 3.8", in the most unfavourable position;
or
hydraulic lift capacity according to !ISO 10567:2007, 3.11"
whichever is less.
The volumetric rating of the bucket shall be determined according to !ISO 7451:2007".
NOTE The mass and the volumetric rating of the bucket and the density of the material have to be taken
into account when a bucket is selected for a specific application.
5.8.4.3 Object handling application
5.8.4.3.1 General
The rated lift capacity of walking excavators in object handling application shall be determined according
to 5.8.4.3.2.

5.8.4.3.2 Rated lift capacity in object handling
The rated lift capacity in object handling shall be determined according to !ISO 10567:2007, 3.13".
5.8.4.3.3 Rated lift capacity table in object handling
A table of the rated lift capacity in object handling in relation to the reach and turntable position, established by
the manufacturer, shall be provided. Annex B gives an example for such a table. The table(s) shall be
available at the operator's station for each object-handling configuration specified in the operation manual.
5.8.4.3.4 Load safety devices
Walking excavators used in object handling operations and with a maximum rated lift capacity according to
!EN 474-1:2006+A1:2009", 3.5 greater than or equal to 1000 kg, at a minimum lift point radius, as
defined in !3.5 of ISO 10567:2007", or an overturning moment greater than or equal to 40 000 Nm, shall
be equipped with:
a ) an acoustic or visual warning device which indicates to the operator when the rated lift capacity or
corresponding load moment is reached and continues as long as the load or load moment is exceeded.
The rated lift capacity is defined in 5.8.4.3.2. This device may be deactivated while the excavator
equipment is performing operations other than object handling. The activation shall be clearly indicated.
The control of the deactivation shall be within the operator's zone of comfort according to
!EN ISO 6682:2008". A warning sign shall be placed close to the control device indicating the need
for activation during object handling.
b) a boom-lowering control device on the raising boom cylinder(s) in accordance with ISO 8643:1997.
5.8.5 Retrieval and towing
!EN 474-1:2006+A1:2009", 5.15 applies with the exception of 5.15.2 and 5.15.5.
