3 Terms and definitions
For the purposes of this document, the terms and definitions given In ISO 6165 and the following apply.
3.1 General
self-propelled crawler or wheeled machine, with an open body, which transports and dumps or spreads material, loading being performed either by means external to the dumper or by self-loading equipment
base machine
machine with a cab or canopy and operator-protective structures (If required), without equipment or attachments but possessing the necessary mountings for such equipment and attachments
set of components mounted onto the base machine which allows an attachment to perform its design function
self-loading equipment
an integral mounted, bucket-supporting structure and linkage permanently fitted to a compact dumper enabling it to fill its own open body with material
Note 1 to entry: See 4.1.5.
assembly of components that can be mounted onto the base machine or equipment for a specific use
part ofan asemhly or ofa base machine, equipment or an attachment
3.2 Performance
tractive force rimpull
force available between the tyre and the ground to propel the dumper
tractive force with direct drive transmission
tractive force calculated or measured at the maximum engine torque in each forward gear
Note ito entry: The maximum pull could be limited by mass and traction conditions.
tractive force rimpull with powershift transmission (electric drivel (hydrostatic drivel tractive force rimpull given by the calcu1ted or measured pull versus machine speed curves in each forward gear range
Note ito entry: The maximum pull could be limited by mass and traction conditions.
empty body dump and return time
full movement cycle time of a body, door or ejector without load, at the rated engine speed
manufacturer’s rated mass that can be carried by the machine
