ASME B56.1-2004 pdf download.Safety Standard for Low Lift and High Lift Trucks.
This Standard is one of a series that has been formu- lated with the American Society of Mechanical Engi- neers 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 the elements of design, operation, and maintenance; stan- dardization relating to principal dimensions to facilitate interchangeability, test methods, and test procedures of powered and nonpowered industrial trucks (not includ- ing vehicles intended primarily for earth moving or over-the-road hauling); and maintenance of liaison with the International Organizationfor 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 Standard. It is expected, however, that the Standard will find a major application in industry, serving as a guide to manufacturers, pur- chasers, and users of the equipment. For convenience, Standards for Powered and Non- powered Industrial Trucks have been divided into sepa- rate volumes: Safety Standards B56.1 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 Tractors B56.10 Manually Propelled High Lift Industrial Trucks Standardization 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 vii B56.11.5 Measurement of Sound Emitted by Low Lift, High Lift, and Rough Terrain Powered Industrial Trucks B56.11.6 Evaluation of Visibility From Powered Industrial Trucks B56.11.7 Liquefied Petroleum Gas (LPG) Fuel Cylin- ders (Horizontal or Vertical) Mounting — Liquid Withdrawal — for Powered Indus- trial Trucks Safety standards that were previously listed as B56 volumes but now have different identification due to a change in standards development assignments are as follows: NFPA 505 Fire Safety Standard for Powered Indus- trial Trucks Type Designations, Areas of Use, Maintenance and Operation (for- merly B56.2) UL 583 Standard for Safety for Electric-Battery- Powered Industrial Trucks (formerly B56.3) UL 558 Standard for Safety for Internal Combus- tion Engine-Powered Industrial Trucks (formerly B56.4) B56 volumes that have been withdrawn: B56.7 Industrial Crane Trucks B56.11.3 Load Handling Symbols for Powered Indus- trial Trucks 3287 Powered Industrial Trucks: Symbols for Operator Controls and Others Displays If adopted for governmental use, the references to other national standards in the specific volumes may be changed to refer to the corresponding governmental regulations. The use ofpowered and nonpowered industrial trucks is subject to certain hazards that cannot be completely eliminated by mechanical means, but the risks can be minimized by the exercise ofintelligence, care, and com- mon sense. It is therefore essential to have competent and careful operators, physically and mentally fit, and thoroughly trained in the safe operation of the equip- ment and the handling of the loads.
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
