3.1.1

scraper

self-propelled or towed crawler or wheeled machine which has a bowl with a cutting edge positioned between the axles, and which cuts, loads, transports, discharges and spreads material through its forward motion

Note 1 to entry: The loading through a forward motion can be assisted by a powered mechanism (elevator) fixed to the scraper bowl.

3.1.2

towed scraper

scraper that is not self-propelled but which is propelled instead by a towing machine on which the operator's station is located

[SOURCE:SOURCE: ISO 6165:2012, 4.7.1]

3.1.3

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 scraper

[SOURCE:SOURCE: ISO 6746‑1:2003, 3.3]

3.1.4

equipment

set of components mounted onto the base machine to fulfil the primary design function

3.1.5

attachment

optional assembly of components that can be mounted onto the base machine for a specific use

3.1.6

component

part or an assembly of parts of a base machine, equipment or an attachment

3.2.1

operating mass

mass of the base machine with empty bowl, equipment specified by the manufacturer, operator (75 kg), full fuel tank and full lubricating, hydraulic and cooling systems

3.2.2

payload

manufacturer’s rated mass that can be carried in the scraper bowl

3.2.3

loaded mass

sum of the operating mass and the payload loaded in accordance with ISO 6485

3.2.4

axle distribution

percentage of machine mass or the actual mass of each axle, empty and loaded

3.2.5

shipping mass

mass of the base machine with empty bowl, without operator, with full lubricating, hydraulic and cooling systems, 10 % of fuel tank capacity and with or without equipment, cab, canopy and/or operator protective structure, as stated by the manufacturer

3.2.6

cab [canopy] [ROPS] [FOPS] mass

mass of cab [canopy] [ROPS (roll-over protective structure)] [FOPS (falling-object protective structure)] with all components and mountings required to secure it to the base machine

3.3.1

push-pull or dual loading

mode of operation which allows one scraper to assist in loading another by pushing or pulling through engagement devices which usually include push plates, a hook and a bail

3.4.1

net power

power obtained on a test bed at the end of the crankshaft or its equivalent, at the corresponding engine speed, with the equipment and auxiliaries listed in ISO 15550:2002, Table 1, column 2, and required in column 3 (fitted for engine net power test)

Note 1 to entry: If the power measurement can only be carried out with a mounted gearbox, the losses in the gearbox should be added to the measured power to give the net engine power.

3.4.2

maximum travel speed

maximum speed that can be obtained on hard level surfaces in each of the forward and reverse gear ratios available, with scraper bowl empty

3.4.3

rimpull

force available between the tyre and the ground to propel the scraper

3.4.4

rimpull with direct drive transmission

rimpull calculated or measured at the rated engine speed and at maximum engine torque in each forward speed

Note 1 to entry: The maximum pull can be limited by mass and traction conditions.

3.4.5

rimpull with power shift transmission [electric drive] [hydrostatic drive]

rimpull given by the calculated or measured pull versus machine speed curves in each forward gear range

Note 1 to entry: The maximum pull can be limited by mass and traction conditions.
