This standard refers to the contents of the definition, structural safety factor, control, design basis of the lifting mechanism, system protection and other chapters of the American standard ANSIA92.5-1980 "Boom-type aerial work platform".
This standard also refers to the design basis and control of the working platform and lifting mechanism assembly of the American standard ANSIA92.6-1979 "Self-propelled aerial work platform". With the increasing use of aerial work platforms, their structural types are also increasing year by year. In order to meet the needs of industry development, we have formulated five product standards, namely "Sleeve Cylinder High-fixed Working Platform", "Boom-type Aerial Working Platform", "Scissor-type Aerial Working Platform", "Stable Column Aerial Working Platform" and "Truss Aerial Working Platform", based on the original JJ82-91 "Aerial Working Platform" industry standard according to the different structural types of the products, to guide the design, manufacture and use of various products. From the date of implementation, this standard will replace Appendix A of J82-91 as the standard appendix.
This standard is proposed by the Standard and Quota Research Institute of the Ministry of Construction. This standard is under the jurisdiction of Beijing Construction Machinery Comprehensive Research Institute, the technical unit responsible for mechanical equipment and vehicle standards of the Ministry of Construction.
The drafting units of this standard are: Building Mechanization Research Institute of China Academy of Building Research and Shanghai Building Electric Tool Factory.
The main drafters of this standard are: Wang Zhenfeng, Liu Zijin, Jing Qizuo, Zhao Hongxue and Wang Zhongliu. This standard is entrusted to the Building Mechanization Research Institute of China Academy of Building Research for interpretation.
