4、t(回柱绞车) introduction,Drawing hoist is a new type of mine auxiliary transportation equipment.,4. Drawing hoist introduction,It mainly used to dismantle and recycling mine stope face of blind mechanical equipment. Traction big and traction speed slow is the main drawing hoist performance requirements.
5、 With the improvement of mechanized degree, it is more and more widely used in mechanization mining face, as installation, recycling of various equipment says spare parts. Drawing hoist except to drawing and caving, also can be used to work hauling and scheduling vehicles.,4. Drawing hoist introduct
6、ion,Drawing hoist mainly consists of electric motor, coupling(联轴器), reducer, the drum device and electric hydraulic brake(电液制动器) etc. It can be divided into 4 parts:Electric motor（电动机）Reducer（减速器）Drum device（卷筒装置）Base（底座） Now, let me introduce the 4 parts one by one.,4. Drawing hoist introduction,El
7、ectric motor: It is the power source of the whole product, the device of translate the electric energy(电能) into kinetic energy(动能).,4. Drawing hoist introduction,The effect of reducer is to reduce the speed , and increase torque(力矩),thereby increase the tension(拉力).,4. Drawing hoist introduction,4. Drawing hoist introduction,Drum device (卷筒装置)is used to roll the steel wire rope(钢丝绳),4. Drawing hoist introduction,Base(底座)：It is the base of the product. Its used to fasten the whole machine.,Overall figure of drawing hoist,The animation of the machine,Thank you!,The end,
