由工程机械研究所設計广州重机厂試制的65吨300大气压三級套管式双柱塞高压泵的手动电动液压千斤頂,經过工业試驗和有关单位鉴定,認为性能良好,結构紧凑,工作安全可靠,現已定型投入生产。該千斤顶是船塢、炼油厂、机械工厂、建筑施工、修造火車、建筑鉄路桥梁、特别是搶修預制桥梁所不可缺少的一种較先进的有效工具,既能电动又能手动,其性能規格如下:
The manual electro-hydraulic jacks of the 65-ton, 300-barrel, three-stage, double-plunger high-pressure pump pilot-scaled by the Guangzhou Engineering Machinery Research Institute were designed by the Engineering Machinery Research Institute. After industrial tests and relevant unit identification, it is considered that the performance is good and the structure is compact. Safe and reliable, it has been put into production. The jack is an indispensable and effective tool for shipyards, oil refineries, machinery factories, building construction, building trains, building roads and bridges, and particularly repairing prefabricated bridges. It is both electric and manual, and its performance specifications are as follows:
