二十冶研制成功 DY—1型电子力矩限制器二十冶吊运公司电子实验室,设计制造出一种新型的 DY—1型电子力矩限制器,于1985年9月正式安装到大型起重机上进行实际使用。通过工作运行验证表明,这种新型力矩限制器,与国外同类产品的技术状况相当,完全可以取代进口产品,为实现大型起重机力矩限制器国产化迈出了可喜的一步。 Twenty Metallurgical Successfully Developed DY-1 Electronic Torque Limiter Twenty Metallurgical Lifting Company Electronic Lab designed and manufactured a new type of DY-1 electronic torque limiter which was formally installed on a large crane in September 1985 Actual use. Through the verification of working operation, it shows that this new type of torque limiter, which is equivalent to the technical condition of similar foreign products, can completely replace imported products and takes a gratifying step toward the localization of large crane torque limiter.
