江西省机械厅于1987年8月20～21日在山西昔阳县对南昌通用机械厂生产的LZB—120型防爆立瓜装载机进行了技术鉴定。出席会议的有开滦煤矿等12个单位的21名代表。与会代表认为,该机已达国外80年代同类产品水平,一致同意鉴定并投入批量生产。煤炭系统的代表对该机发生强烈兴趣,煤炭部技术开发公司有关领导要求开滦煤矿和南昌通用机械厂通力合作,对以LZB—120型防爆立爪装载机为主体的机械化作业线作出可行性分析。该机1987年5月15日正式投入使用,8个月内掘进588米、挖方10584米~3,在6、7月份分别创独头掘进128卷和92米的记录。设备使用正常、3个月内未出过事故,与瑞典8HR立瓜装载机相比,扒抓力大,运输槽宽,通过大块岩石能力强。
Mechanical Hall of Jiangxi Provincial Government conducted technical appraisal on LZB-120 explosion-proof Liguar Loader produced by Nanchang General Machinery Factory in Xiyang County, Shanxi Province from August 20 to 21, 1987. Twenty-one representatives from 12 units including Kailuan Coal Mine attended the meeting. Participants believe that the aircraft has reached the level of similar products in the 1980s abroad, agreed to identify and put into mass production. Representatives of the coal system took a strong interest in the aircraft. The relevant leaders of the technology development company of the Ministry of Coal Mine demanded that Kailuan Coal Mine and Nanchang General Machinery Factory cooperate with each other and make feasibility study on the mechanized operation line with LZB-120 explosion-proof claw loader as the main body analysis. The aircraft was officially put into use May 15, 1987, within 8 months of drilling 588 meters, digging 10584 m ~ 3, in June and July were the first to dig 128 volumes and 92 meters of records. The equipment is in normal use and no accident has occurred within 3 months. Compared with the Swedish 8HR Liguar Loader, it has the advantages of large gripping force, wide transport slot and strong ability of passing large rocks.
