钢丝绳电动葫芦是一种轻小型起重设备, 具有结构紧凑、重量轻、体积小、零部件通用性强、操作方便等优点。减速器采用硬齿面传动设计，寿命长，机械效率高。电机采用锥形转子制动电动机，具有上下双向安全限位装置。 MDI型电动葫芦具有快速和慢速两种起升速度，起吊平稳准确。 CDI、MDI型钢丝绳电动葫芦可广泛用于提升重物或安装在单梁起重机，直线、曲线的工字梁上，也可用于葫芦双梁、龙门起重机或悬臂吊上，是工矿企业、铁路、码头、仓库中常用的起重设备。 CDI MDI type wire-rope electric hoist is a kind of light-small lifting equipment with advantages of tight structure, light weight, small volume, wide common use and convenient operation etc.If reducers with hard gear surface are applied, it will have long life and high mechanical efficiency. Conic rotor brake motors are equipped which has safety limiter in both up and down directions. MDItype electric hoists have fast and slow lifting speeds which make it lift steadily and accurately. CDI MDI type wire-rope electric hoists can be widely used to hoist heavy objects, or installed on the straight or curve I-steel beam of Single-girder Cranes. They can also be used together with Electric Hoist Double-girder, gantry crane and slewing cranes. All the above has made the electric hoists common in industrial and ore enterprises, railway, wharfs and warehouses.
