11、B56.9 Subcommittee started work on this standard in the direction of the B56 Committee and sponsor, The American Society of Mechanical Engineers (ASME). Following a number of work sessions and ballots within the Subcommittee and the B56 Committee, it was submitted for B56 Committee ballot, public re
12、view, and ASME approval. After obtaining such approval, the Standard was submitted to the American National Standards Institute, Inc. (ANSI). ANSI approved to issue the first edition of this standard as American National Standard B56.9 was granted on August 6, 1987. Following approval by the B56 Com
13、mittee and ASME, and after public review, ASME B56.9- 1992 was approved by ANSI on January 2, 1992. After transferring the management of the B56 Committee from ASME to ITSDF, ASME B56.9- 1992 was reaffirmed and redesignated as ANSI/ITSDF B56.9-2005. After approval by the B56 Committee and after publ
14、ic review, a revision of ANSI/ITSDF B56.9 was approved by ANSI and designated an American National Standard on August 23, 2006. This Standard shall become effective 1 year after its respective Date of Issuance. Part III applies only to trucks manufactured after the effective date. Safety codes and s
15、tandards are intended to enhance public health and safety. Revisions result from committee consideration of factors such as technological advances, new data, and changing environmental and industry needs. Revisions do not imply that previous editions were inadequate. iv ITSDF STANDARDS COMMITTEE ROS

ANSI/ITSDF B56.9-2006 SAFETY STANDARD FOROPERATOR CONTROLLED INDUSTRIAL TOW TRACTORS vi POWERED AND NONPOWERED INDUSTRIAL TRUCKS B56 SERIES INTRODUCTION GENERAL This Standard is one of a series that ha
21、ve been formulated with the Industrial Truck Standard Developing Foundation as Sponsor in accordance with the Accredited Organization method, the procedures accredited by the American National Standards Institute, Inc., and the following scope: Establishment of the safety requirements relating to th
22、e elements of design, operation, and maintenance; standardization relating to principal dimensions to facilitate interchangeability, test methods, and test procedures of powered and nonpowered industrial trucks (not including vehicles intended primarily for earth moving or over-the-road hauling); an
23、d maintenance of liaison with the International Organization for Standardization (ISO) in all matters pertaining to powered and nonpowered industrial trucks. One purpose of the Standard is to serve as a guide to governmental authorities having jurisdiction over subjects within the scope of the Stand
24、ard. It is expected, however, that the Standard will find a major application in industry, serving as a guide to manufacturers, purchasers, and users of the equipment. For convenience, Standards of Powered and Nonpowered Industrial Trucks have been divided into separate volumes: Safety Standards B56
25、.1 Low Lift and High Lift Trucks B56.5 Guided Industrial Vehicles and Automated Functions of Manned Industrial Vehicles B56.6 Rough Terrain Forklift Trucks B56.8 Personnel and Burden Carriers B56.9 Operator Controlled Industrial Tow Trucks B56.10 Manually Propelled High Lift Industrial Trucks Standa
26、rdization Standards B56.11.1 Double Race or Bi-Level Swivel and Rigid Industrial Casters B56.11.4 Hook-Type Forks and Fork Carriers for Powered Industrial Forklift Trucks B56.11.5 Measurement of Sound Emitted by Low Lift, High Lift, and Rough Terrain Powered Industrial Trucks B56.11.6 Evaluation of
27、Visibility From Powered Industrial Trucks B56.11.7 Liquefied Petroleum Gas (LPG) Fuel Cylinders (Horizontal or Vertical) Mounting Liquid Withdrawal for Powered Industrial Trucks Safety standards that were previously listed as B56 volumes but now have different identification due to a change in stand
28、ards development assignments are as follows: NFPA 505 Fire Safety Standard for Powered Industrial Trucks Type Designations, Areas of Use, Maintenance and Operation (formerly B56.2) UL 583 Standard for Safety for Electric-Battery- Powered Industrial Trucks (formerly B56.3) UL 558 Standard for Safety
29、for Internal Combustion Engine-Powered Industrial Trucks (formerly B56.4) If adopted for governmental use, the references to other national codes and standards in the specific volumes may be changed to refer to the corresponding governmental regulations. The use of powered and nonpowered industrial
30、trucks is subject to certain hazards that cannot be completely eliminated by mechanical means, but the risks can be minimized by the exercise of intelligence, care, and common sense. It is therefore essential to have competent and careful operators, physically and mentally fit, and thoroughly traine
31、d in the safe operation of the equipment and the handling of the loads. Serious hazards are overloading, instability of the load, obstruction to the free passage of the load, collision with objects or pedestrians, poor maintenance, and use of equipment for a purpose for which it was not intended or
32、designed. Suggestions for improvement of these Standards, especially those based on actual experience in their application, shall be submitted to the Secretary of the B56 Committee, ITSDF, 1750 K Street NW, Suite 460, Washington DC 20006.
