1 Scope
This International Standard specifies methods for measuring and calculating the tool forces of earth-moving attachments fitted to hydraulic excavators and the hoe equipment of backhoe loaders. It is applicable to hydraulic excavators and backhoe loaders as defined in ISO 6165.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 tool force force generated at the bucket lip or cutting edge, but not at the tips of the teeth, when operating the bucket or arm cylinders independently
3.2 arm cylinder tool force force generated at the bucket lip with the arm cylinder positioned to provide a rotating moment around the arm pivot Note 1 to entry: The bucket lip moves towards the base machine when hoe equipment is used.
3.3 arm cylinder tool force at level crowd 〈shovel equipment〉 horizontal arm cylinder tool force generated by the arm cylinder at the bucket lip when the bucket”s attitude is level and maintained parallel to the ground line and the lip is at the ground line
3.4 bucket cylinder tool force tool force generated at the bucket lip with the bucket cylinder(s) positioned to provide a rotating moment to the bucket around its pivot Note 1 to entry: The bucket lip moves towards the base machine when hoe equipment is used and away from it when shovel equipment is used.
3.5 crowd tool force 〈hydraulic excavators with telescoping boom〉 tool force generated at the bucket lip when the telescoping boom is retracted
3.6 rated tool force tool force, measured or calculated, that the manufacturer publishes
3.7 actual tool force measured tool force generated at the bucket without tipping or sliding occurring
3.8 maximum [arm cylinder] [bucket cylinder] [crowd] tool force largest measured or calculated tool force
3.9 grab [clamshell] closing force force generated between the grab [clamshell] cutting edges or teeth tips when closing
3.10 maximum grab [clamshell] closing force largest measured or calculated grab [clamshell] closing force
