目前,有些工矿企业自制的起重机不符合设计规范和起重机械安全规程要求,在设计、选材、加工、热处理、装配等方面的质量都不如专业生产厂要求严格,质量检验手段跟不上,安全保护装置不齐全,不可靠,不能预防由于操作失误造成的设备故障和人身伤亡事故。因此,加强自制起重机的检查 At present, some cranes manufactured by industrial and mining enterprises do not meet the design specifications and crane safety requirements. The quality in terms of design, material selection, processing, heat treatment and assembly are not as strict as the requirements of professional manufacturing plants, and the quality inspection methods can not keep up. The safety Protection device is not complete, unreliable, can not prevent due to operational errors caused by equipment failure and personal injury accident. Therefore, to strengthen self-made crane inspection
