1999-6-28 Issued by the State Machinery Industry Bureau, implemented on January 1, 2000, JB/T9019.1-199. This standard is a revision of the ZDJB6001.1, 89 screw starter type and parameters. During the revision, the original standard was comprehensively modified. The main technical content was not cavitated. The standard replaced the Appendix A of the standard H86.1-8 from the actual version. It is a reminder appendix. This standard was developed and coordinated by the Beijing Hoisting and Conveying Machinery Research Institute. This standard is the responsibility of the Shijiazhuang Mining Machinery Research Institute. This standard is for the purpose of engineering maintenance and non-compliance. 【Scope

This standard strictly describes the types, basic symbols and connection dimensions of screw gate hoists, JB/T9019.1-1999
Replaces ZB386001.189
This standard is applicable to screw gate hoists (hereinafter referred to as gate hoists) for flat gates in water conservancy, hydropower and municipal water supply and drainage projects. 2 Types
2.1 Gate hoists are divided into two series: general type and remote control type. Each series is divided into two types: single-point and double-point. The general single-point opening machine has both manual and electric driving modes. The appearance of the closing machine is shown in Figures 1-3:
