AS ISO 7132:2021 Earth-moving machinery – Dumpers – Terminology and commercial specifications. 5 Performance characteristics The following performance characteristics are used in connection with dumpers: the International Standard indicates further characteristics and test methods as appropriate; the term number refers to the term as defined in this International Standard. a) ISO net power (engine): see Iso 9249. b) Maximum travel speed: see ISO 6014. c) Tractive force rimpull (3.2.1): 1) Tractive force with direct drive transmission (3.2.1.1); Tractive force rimpull with powershift transmission, electric drive or hydrostatic drive (3.2.1.2). d) Empty body dump and return time (3.2.2). e) Steering capability 1) Turning radius: see ISO 7457. Machine clearance diameter: see ISO 7457. f) Braking performance: based on requirements given in ISO 3450. g) Payload (3.2.3). 6 Commercial literature specifications (SI units) 6.1 Engine Specify the characteristics: a) manufacturer and model; b) compression-ignition (diesel) or spark-ignition; c) type of cycle (two- or four-stroke); d) naturally aspirated, mechanically supercharged, or turbo-charged, with or without aftercooling; e) number of cylinders; f) bore; g) stroke; h) displacement; I) cooling system (air or water cooled); j) type of fuel; k) power, flywheel net at r/min; l) torque, maxirnum at r/min; m) starter type; n) electrical system V. 6.2 Transmission Specify the type, for example: — manual shift with flywheel clutch; — power shift with torque converter; — hydrostatic; — electric; — number of gear speeds, forward and reverse; — travel speeds (forward and reverse). A graph of rimpull versus speed should be shown. 6.3 Drive axle(s) Specify the type, for example: — steerable; — fixed, oscillating and/or suspended; — hydrostatic; — electric; — bevel gear and pinion; — differential — standard, non-slip, limited slip or lock-up; — planetary final drive. 6.4 Steering 6.4.1 Type Specify type in accordance with ISO 5010, for example: — articulated frame; — front-wheel steer; — rear-wheel steer; — all-wheel steer; — crawler skid steer; — boosted, manual, hydrostatic; — emergency steer method. 6.4.2 Performance Specify: — turning radius , left and right; — machine clearance diameter.AS ISO 7132 pdf download.
