1  Scope
This International Standard provides a uniform method of calculating, and a test method for validating, rated lift capacity as presented in commercial literature for pipelayers and wheeled tractors or loaders equipped with a vertical-only pivoted, hydraulic or mechanically operated, side boom. The rated lift capacity considers hoist mechanism limits, tipping loads and rope factor. After the lift capacity has been calculated and validated, a reduction factor is applied to establish the rated lift capacity for the specific pipelayer or wheeled machine configuration. This International Standard applies to machines having a lift capacity greater than 10 000 N when used in lifting applications. It includes pipelayers as defined in ISO 6165 and ISO 7136, and wheeled tractors and loaders as defined in ISO 6165, ISO 6747 and ISO 7131.

3  Definitions
For the purposes of this International Standard, the following definitions apply.
3.1 load
External force including the weight of attaching equipment applied at the load hook. See figures 1 and 2.
3.2 lift point line
Vertical line through the centre of the load hook.
3.3 outrigger
Extendable or fixed arm attached to the base machine which rests on the supporting surface and defines the tipping line. See figures 7 and 8.
3.4 tipping line
balance point fulcrum
(See 3.4.1 to 3.4.4.)
3.4.1 tipping line (for crawler machines)
Outer edge of the outer track link rail on the boom side of the machine. See figure 1.
3.4.2 tipping line (for wheeled machines with non-oscillating axle)
Line connecting the centres of contact of the front and rear tyres with the ground reference plane on the boom side of the machine. See figures 2, 3 and 5.
3.4.3 tipping line (for wheeled machines with oscillating axle)
Line in the ground reference plane connecting the centre of contact of the tyre on the rigid axle on the boom side of the machine and the vertical line through the centre of oscillation of the oscillating axle.See figures 4 and 6.
3.4.4 tipping line (for machines with outriggers)
Line in the ground reference plane connecting the centres of contact of the outrigger pads on the boom side of the machine. See figures 7 and 8.
