ASME B56.1:2004 pdf download.Safety Standard for Low Lift and High Lift Trucks
1 SCOPE
This Standard defines the safety requirements relating to the elements of design, operation, and maintenance of low lift and high lift powered industrial trucks con- trolled by a riding or walking operator, and intended for use on compacted, improved surfaces.
2 PURPOSE
The purpose of this Standard is to promote safety through the design, construction, application, operation, and maintenance oflow lift and high lift powered indus- trial trucks. This Standard may be used as a guide by governmental authorities desiring to formulate safety rules and regulations. This Standard is also intended for voluntary use by others associated with the manufacture or use of low lift and high lift powered industrial trucks.
3 INTERPRETATION
3.1 Mandatory and Advisory Rules To carry out the provisions of this Standard, all items in Parts II, III, IV, and V are mandatory except those including the word should, which are recommendations. 3.2 Classification of Approved Trucks The word approved means the classification or listing of trucks as to fire, explosion, and/or electric shock hazard by a nationally recognized testing laboratory, i.e., a laboratory qualified and equipped to conduct examinations and tests such as those prescribed by Underwriters Laboratories, Incorporated. 3.3 Requests for Interpretation The B56 Committee will render an interpretation of any requirement of this Standard. Interpretations will be rendered only in response to a written request sent to the Secretaryofthe B56Committee, ASME International, Three Park Avenue, New York, NY 10016-5990. The request for interpretation shall be in the following format. Subject: Cite the applicable paragraph number(s) and provide a concise description. Edition: Cite the applicable edition of the pertinent standard for which the interpretation is being requested. Question: Phrase the question as a request for an inter- pretation of a specific requirement suitable for general understanding and use, not as a request for approval of a proprietary design or situation. The inquirer may also include any plans or drawings that are nec- essary to explain the question; however, they should not contain proprietary names or information. ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available. Further, per- sons aggrieved by an interpretation may appeal to the cognizant ASME Committee or Subcommittee. ASME does not “approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device or activity. 3.4 Metric Conversions The values stated in metric units are to be regarded as the standard. U.S. Customary units are maintained in the User’s section (in parentheses) as information for those not familiar with metric units. The conversion to U.S. Customary units is a direct (soft) conversion from SI units.
4 GENERAL SAFETY PRACTICES
4.1 Introduction 4.1.1 Part II contains requirements for the users of powered industrial trucks. Included are requirements for operator qualifications and training, operating safety rules, and maintenance practices. 4.1.2 Unusual operating conditions may require additional safety precautions and special operating instructions. 4.1.3 Supervision is an essential element in the safe operation of powered industrial trucks. 4.2 Modifications, Nameplates, Markings, and Capacity 4.2.1 Except as provided in para. 4.2.2, no modifica- tions or alterations to a powered industrial truck that may affect the capacity, stability, or safe operation of the truckshallbe made withouttheprior writtenapprovalof the original truck manufacturer or its successor thereof. When the truck manufacturer or its successor approves a modification or alteration, appropriate changes shall be made to capacity plates, decals, tags, and operation and maintenance manuals. 4.2.2 If the truck manufacturer is no longer in busi- ness and there is no successor to the business, the user may arrange for a modification or alteration to a pow- ered industrial truck, provided however, the user (a) arranges for modification or alteration to be designed, tested, and implemented by an engineer(s) expert in industrial trucks and their safety (b) maintains a permanent record of the design, test(s), and implementation of the modification or alter- ation (c) makes appropriate changes to the capacity plate(s), decals, tags, and operation and maintenance manuals (d) affixes a permanent and readily visible label on the truck stating the manner in which the truck has been modified or altered together with the date of the modification or alteration, and the name ofthe organiza- tion that accomplished the tasks
