2012年10月11日,中信重工机械股份有限公司研制成功JKYB-φ3.5×2.5m型液压防爆提升机。该液压防爆提升机采用2台RD03型行星齿轮减速器的双边驱动配置,直径为3.5m,800kW装机功率,采用了4台200kW电动机,4台250L轴向柱塞泵,12台液压马达,是目前国内规格最大、装机功率最大、静张力最大的单筒双驱液压防爆提升机。与国内外同类产品相比,具有自动减速、自动停车等12项安全防护装置特性,可实现高速轻载和重载低速运行工况。该类提升机主要用于有沼气及其他易燃易爆物的煤矿,主要为井下运输或辅助运输服务,可垂直升降煤、矿石、材料、设备及人员,也可供金属矿、非金属矿、冶金、建筑、港口和其他工程作起重、提升、运输之用。
October 11, 2012, CITIC Heavy Industries Machinery Co., Ltd. successfully developed JKYB-φ3.5 × 2.5m hydraulic explosion-proof hoist. The hydraulic explosion-proof hoist with two RD03-type planetary gear reducer bilateral drive configuration, diameter 3.5m, 800kW installed power, using four 200kW motor, four 250L axial piston pump, 12 hydraulic motors, is Currently the largest domestic specifications, the largest installed power, static tension largest single cylinder dual-drive hydraulic explosion-proof hoist. Compared with similar products at home and abroad, with 12 automatic safety devices, such as automatic deceleration, automatic parking features, can achieve high-speed light-load and heavy-load low-speed operation conditions. This type of hoist is mainly used in coal mines with biogas and other flammable and explosive materials, mainly for underground transportation or auxiliary transportation services, which can vertically lift coal, ore, materials, equipment and personnel, and also can be used for metal ore and non-metal mine , Metallurgy, construction, ports and other projects for lifting, upgrading, transport purposes.
