Rated load of traction machineWhen the traction ratio is 1:1 and the balance coefficient is 0.40, it means the rated load of the car in the tangential traction of the traction wheel.National Standard of the Peoples Republic of ChinaGBT 10058-1997Specifications for LiftsForewordThe national standard is the amendment to the original Specifications for Lifts GB 10058-88, main content of which are as the following: 1) In chapter “ whole performance”, the regulations of classification are canceled, which include acceleration and redarded speed of vertical vibration, acceleration and redarded speed of horizontal vibration, as well as indicators of noise and leveling accuracy.2) For improving operation efficiency of the lifts, the requirements to open time and close time of passenger lifts are added in the national standard.3) In chapter “reliability”, the regulation of classification of reliability indicator is canceled; examining requests to control cabinet which is considered as commodity component are added in the national standard.4) In Appendix A, specific regulations are made to technical documents kept in manufacturer after sale of lifts.The standard will replace GB 10058-88 since the effective date.Appendix A is a standard appendix.The standard is proposed by Ministry of Construction of the Peoples Republic of China.The standard is under the jurisdiction of China Lift Standardization Technical Committee.This standard is drafted by Institute of Construction Mechanization of China Academy of Building Research, Beijing Schindler Elevator Co., Ltd in China, Tianjin Otis Elevator Co., Ltd in China, and Guangzhou Elevator Industry Co., Ltd.The standard is mainly prepared by Kerong Peng, Guozhen Zhang, Xiaohui Xi and Xizhi Yang.The standard was firstly issued in 1988 and firstly revised in 1997. 1 ScopeThe standard formulates technical specifications of passenger lifts and freight lifts, inspection provisions, indication marks, package, transportation and storage.The standard is applicable to power-actuated traction-type or compulsory-type passenger lifts and freight lifts whose rated speed is not higher than 2.5m/s;The standard is inapplicable to hydraulic lifts and dumbwaiter lifts. 2Normative ReferencesThe articles included in the following standards become the articles of the national standard by quotation. The listed editions are efficient while the standard is published. All standards will be revised, so all parties who use the following standards should consider the latest edition as possible.GB 2828-87In-batch Check Counting Sampling Process and Sample Table(suitable for continuous batch)GB 7588-1995Safety Code for Manufacturing and Installation of Lifts (eqv EN 81-1: 1985)In this code, Chapter 1, Chapter 2, Chapter 3, Chapter 4, Section 7.2.1 (partial), Section 8.17.1, Section 9.1.2b), Section 9.9.6.2 (partial), Section 12.6 (partial), Section 13.1.1.3, Section 15.2.3.2 (partial), Section 16.2a)6) (partial), Appendix C, Appendix E, Appendix G, Appendix M and Appendix ZA are recommendatory; the rest are obligatory. This code is the revised version of GB 7588-1995 Safety Rules for the Construction and Installation of Lifts (equivalent to EN81-1: 1985) on the base of EN81-1: 1998 Safety Rules for the Construction and Installation of Lifts issued by European Committee for Standardization (CEN). This revised version is equivalent to EN81-1:1998 in the fields of technical contents and article numbering. Compared with EN81-1:1985, EN81-1:1998 changed huge parts of contents. The new version increases plenty of new technical contents and new calculation method. Besides a few parts are changed according to the Chinse lift situations, this revised version is basically compliant to the contents of EN81-1:1998. In the revised version, the following major technical contents are changed: 1. GB 7588-1995 version has a concise and definite application scope, so this revised version reserve the application scope of GB 7588-1995. For the purpose of presenting the definiteness, the revised version adds sickbed lift, deletes the application scope of EN81 1:1998. 2. This revised version makes the following changes from the quoted terms and conditions of EN81-1:1998. (1) If the international standards or overseas advanced standards listed in Quoted Codes of EN81-1:1998 have already equivalently adopted as Chinese national standards (GB) or industry standard, then this quoted terms and conditions are directly named as the corresponding Chinese code number. (2) The code name that is not included in the Quoted Codes and make no mention in EN81-1:1998 has some content involved in the Chinese code, so it is also listed in the Quoted Codes of this code. For instance, in Clause :16.2a)6), the original text use CENELEC symbols is listed in Chinese national standard GB/T 4728, Graphical Symbols for Electrical Diagrams. And Clause 9.1.2c) is listed in the Chinese national standard GB 8903, Wire Ropes for Lifts.
