ASME B30.22-2023 铰接式悬臂起重机安全标准 PDF下载
ASME B30.22 针对铰接式悬臂起重机(Articulating Boom Crane)——即多节折叠臂、可伸缩并通过铰接关节实现“越障”作业的汽车底盘或自行走起重机——给出结构、液压、电气及安全系统要求。2023 版规定主臂与副臂铰点必须设置双冗余锁止销、超载时臂架自动回缩至安全角度;要求额定载荷图按 5° 倾角风速 12 m/s 计算,并标注“作业区域限制弧”防止关节过度折叠;新增 360° 连续回转齿轮盘每 200 工作小时润滑、每 5 年一次焊缝 MT+UT 抽检,以及遥控操作时信号丢失 3 s 内自动减速停机等条款,为市政抢修、设备安装、石化检修等复杂空间吊装提供高安全等级技术规范 。
