从1986年中信重型机械公司（原洛阳矿山机器厂）引进瑞典，ABB公司提升机技术及4m样机之后，经过消化吸收和自行研制开发，在此基础上，陆续设计制造了几十台大型直联悬臂（即提升机不带减速器，与电机共用一根轴）多绳摩擦式提升机。其中采用了两种新技术：提升机主轴与电动机 Since 1986, CITIC Heavy Machinery Company (formerly Luoyang Mining Machinery Factory) to Sweden, ABB hoist technology and 4m prototype, after digestion and absorption and self-development, on this basis, one after another to design and manufacture of dozens of large-scale direct Cantilever (ie, hoist without gearbox, and motor sharing a shaft) Multi-rope friction hoist. Which uses two new technologies: hoist spindle and motor
