| TECHNICAL REFERENCE When you contract for Crane & Hoist Engineering services, you can be assured of compliance with appropriate specifications, codes and standards, along with safe and economical designs. HERE ARE THE MOST IMPORTANT SOURCES FOR SPECIFICATIONS, CODES AND STANDARDS FOR CRANES AND HOISTS WHICH ARE MANUFACTURED AND SOLD IN THE USA: OSHA, Occupational Safety & Health Administration,www.osha.gov. Prior to OSHA there were numerous industry and state consensus standards regarding safety in the workplace and the proper methods for manufacturing equipment. But until 1971 when OSHA was created as a Federal agency, none of these standards had any real teeth. The applicable codes are broken into 29CFR 1910 for General Industry and 29CFR 1926 for Construction. WISHA, Washington Industrial Safety and Health Act, Section 18 of OSHA encourages States to develop and operate their own job and safety and health programs. OSHA approves and monitors the State plans and many States have gone ahead with their own plans. WISHA is the acronym commonly applied for the State of Washington's plan. Oregon www.orosha.org and California also have plans. ASME, American Society of Mechanical Engineers, www.asme.org. This engineering society has, over a period of nearly 100 years, developed the American National Safety Standard B30 for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings. Standard B30 is broken into some 30 different safety and performance standards covering almost all types of lifting equipment, including mobile cranes. CMAA, Crane Manufacturers Association of America, www.mhia. This is an independent trade association of the larger manufacturers of overhead cranes. The member companies regulary publish industry standard specifications for Top Running, Under Running, Single and Multiple Girder Cranes. CMAA Specifications 70 and 74 are very often called out in crane specifications and proposals for general industry applications. HMI, Hoist Manufacturer's Institute, www.mhia. An affiliate of the Material Handling Industry of America (MHIA), this is a trade association of manufacturers of hand chain hoists, trolleys, air chain and air rope hoists, and electric chain and electric wire rope overhead hoists. This group publishes standards for design, performance and proper operation of the equipment they manufacture. The HMI H1 through H5 Hoist Duty Class Ratings are commonly used in the overhead hoist industry. ANSI, American National Standards Institute, www.ansi.org. A private, nonprofit organization that administers and coordinates the U.S. voluntary standardization and conformity assessment system. Their mission is "to enhance both the global competitiveness of U.S. business and the U.S. quality of life by promoting and facilitating voluntary consensus standards and conformity systems, and safeguarding their integrity." The ASME B30 codes for cranes and hoists are examples of ANSI standards. AWS, American Welding Society, www.aws.org. A nonprofit organization which has the goal of advancing science, technology and application of welding. ANSI/AWS Standard D14.1, which is the "Specification for Welding of Industrial and Mill Cranes and other Material Handling Equipment," is often specified regarding crane manufacture. SAE, Society of Automotive Engineers, www.sae.org. An engineering society which provides standards for all types of vehicles including mobile cranes. The "SAE Crane Standards Manual" number HS-2000 is a compilation of the most common mobile crane standards. Back to top |
