ASME B30.4-2020 门座起重机和基座式起重机.pdf简介：

ASME B30.4-2020 "门座起重机和基座式起重机"标准是美国机械工程师学会（American Society of Mechanical Engineers，ASME）制定的一份关于移动式工业起重机设计、制造、安装、检验和维护的规范。这份标准主要针对门座起重机和基座式起重机，这类起重机广泛应用于港口、码头、仓库和其他工业设施，用于重型物料的吊运和装卸。

该标准涵盖了多个关键方面，包括但不限于： 1. 起重机的结构和材料要求：定义了设计和制造过程中的强度、刚度、耐腐蚀性等标准。 2. 安全装置：规定了必须安装的安全设备，如起重量限制器、防风制动系统、行程限位器等。 3. 操作和控制：详细描述了操作规程、控制系统要求以及应急响应措施。 4. 安装、检验和维护：提供了关于安装过程中的要点，以及定期检查和维护的建议，以确保设备的稳定运行和用户安全。

2020版更新了部分内容，以反映最新的技术发展和行业最佳实践，旨在提高起重机的性能、可靠性和安全性。任何设计、制造和使用这类起重机的组织都需要遵循这一标准，以符合法规要求和确保设备性能。
