Earth-moving machinery - Rubber-tyred machines - Steering requirements (ISO 5010:1992 modified)

This European Standard specifies steering system tests and performance criteria for evaluating the steering capability of rubber-tyred self-propelled earth-moving machines having a machine speed, determined in accordance with ISO 6014:1986, greater than 20 km/h.
It applies to tractors, loaders, backhoe loaders, excavators, dumpers, tractor-scrapers and graders equipped with either manual (unassisted) steering, power-assisted steering of fully powered steering as defined in
ISO 6165:1997.
This European Standard excludes rollers, compactors and pipelayers.

Erdbaumaschinen - Radfahrzeuge - Lenkvermögen (ISO 5010:1992 modifiziert)

Diese Europäische Norm legt Anforderungen und Prüfungen für Lenkanlagen zur Beurteilung des Lenk-vermögens von gummibereiften, selbst fahrende Erdbaumaschinen, die für Fahrgeschwindigkeiten, ermittelt nach ISO 6014:1986, über 20 km/h ausgelegt sind, fest.
Sie gilt für Schlepper, Lader, Baggerlader, Bagger, Muldenfahrzeuge, Scraper und Grader, wie in ISO 6165:1997 definiert, die entweder mit Muskelkraftlenkung (ohne Fremdhilfe), Hilfskraftlenkung oder Fremdkraftlenkung ausgerüstet sind.
Diese Europäische Norm schließt Walzen, Bodenverdichter und Rohrleger aus.

Engins de terrassement - Engins équipés de pneumatiques - Systèmes de direction (ISO 5010:1992 modifié)

La présente norme européenne prescrit les essais et les critères de performance pour l’évaluation de la capacité du
système de direction des engins de terrassement automoteurs équipés de pneumatiques, dont la vitesse au sol,
déterminée conformément à l'ISO 6014:1986, est supérieure à 20 km/h.
Elle est applicable aux tracteurs, chargeuses, chargeuses-pelleteuses, pelles, tombereaux, décapeuses
automotrices et niveleuses, tels que définis dans l'ISO 6165:1997, équipés de systèmes de direction manuelle,
assistée, ou à servodirection.
La présente norme européenne exclut les rouleaux, les compacteurs et les tracteurs poseurs de canalisations.

3.2.1 normal steering power source means for providing power to effect steering in either power-assisted or fully powered steering systems, for example, hydraulic pump, air compressor, electric generator 3.2.2 emergency steering power source means for providing power to the emergency steering system, for example, hydraulic pump, air compressor, accumulator, battery 3.2.3 failure of normal steering power source complete and instantaneous loss of a normal steering power source output. It is assumed that not more than one failure will occur at the same time 3.3 steering control element manual control means by which the operator provides muscular power inputs to the steering systems to effect the desired steering of the machine, including the typical steering-wheel or any equivalent manual control means 3.4 steering effort necessary force exerted by the operator on the steering control element in order to steer the machine 3.5 steering angle total displacement angle between the front wheels and the rear wheels as they move about one or more vertical steering axes from their normal straight-ahead condition to a turned condition NOTE 1 The steering angle for multiple axle machines is determined between the wheels at the farthest forward and the farthest rearward axle. NOTE 2 Ackermann steering inherently has a greater steering angle on the side of the machine toward the inside of the turn as compared to the wheels on the outside of the turn. Therefore, where Ackermann steering is involved, the location of the steering angle measurement also needs to be specified. A steering angle accomplished by a combination of geometries incorporating Ackermann steering is included, and also requires the location of steering angle measurement to be specified. 3.6 tyre circle outer tyre clearance diameter determined in accordance with clause 9 3.7 working circuit pressure that nominal pressure applied to the specific circuit by the pump(s) SIST EN 12643:2000+A1:2008
