1、 ANSI/ASABE S602.2 MAY2015 General Safety Standard for Agricultural Tractors in Scraper Applications American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members worldwide, who are dedicated to advancement of engineering applicable to agric
2、ultural, food, and biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally agricultural field equipment, farmstead equipment, structur
3、es, soil and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Practices, and Data are informational and advisory only. Their u
4、se by anyone engaged in industry or trade is entirely voluntary. The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance with applicable ordinances, laws and regulations. Prospective us
5、ers are responsible for protecting themselves against liability for infringement of patents. ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“, regardless of the revision approval date. Newly developed Standa
6、rds, Engineering Practices and Data approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard requires verification by ANSI that the requirements for due
7、 process, consensus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple
8、 majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Additionally, procedures of ASABE require that acti
9、on be taken periodically to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

10、ight American Society of Agricultural and Biological Engineers 1 ANSI/ASABE S602.2 MAY2015 Revision approved May 2015 as an American National Standard General Safety Standard for Agricultural Tractors in Scraper Applications Developed by the ASABE Tractors Subcommittee and approved by the Power and
11、Machinery Division. Adopted as an ASABE Standard and approved as an American National Standard August 2008; revised March 2014; revision approved by ANSI April 2014; revised by ASABE and approved by ANSI May 2015. Keywords: Safety, Scraper, Tractors 1 Scope 1.1 This Standard provides safety requirem
12、ents for agricultural scraper tractors as defined in ASAE S390, when used in construction environments, as defined in ISO 6165. 1.2 This standard does not apply to agricultural tractors used in traditional agricultural applications, such as land leveling. 1.3 Agricultural scraper tractors that meet
13、the requirements of this standard are suitable for use in traditional agricultural tractor applications. 2 Normative References The following referenced documents are indispensable for the application of this document.

In the event of conflicting requirements, the requirements of this standard shall ta
20、ke precedence. 5 Protective Structures 5.1 Roll over protective structures (ROPS) shall be in accordance with ISO 3471. 5.1.1 Category three of ISO 3471, wheeled earth-moving machine: loader, tractor-dozer, pipe layer, landfill compactor, skid-steer loader, backhoe loader and trencher type, shall be
21、 used for force and energy calculations. 5.1.2 The mass used need not include the mass of the towed scraper or payload; however, it shall include the agricultural scraper tractor, fuel, operator, and ballast. 5.2 Agricultural scraper tractors intended for use in applications where a risk of falling
22、objects are present shall be equipped with a FOPS meeting the requirements of SAE J167, ISO 3449 level I, or ISO 3449 level II, as appropriate to the application. 6 Operator Station 6.1 Location, movement, and identification of operator controls shall be in accordance with ASABE/ISO 15077. 6.2 Seat
