平面转弯带式输送机是指采用平输送带实现平面转弯的特种带式输送机，也可伴随着平面转弯进行竖向凸凹弧弯曲，构成空间转弯。它是通过采取一定的特殊措施使输送机运行时产生一个向外的离心推力来克服由转弯造成的输送带张力的向心合力，从而保证输送带的转弯运行。该平面转弯带式输送机可实现输送带的自然变向，而不需采用特殊结构的专用输送带。

平面转弯带式输送机的使用可以使得原先无法实现的运输线路得以实现,或者使用常规胶带机方式实现起来非常复杂的运输通道得以大大简化,从而减少转运站的投资,减少污染点、减少设备故障点、减少维修和操作人员等。可广泛用于煤炭、冶金、建材、粮食、化工、电力、港口等领域，具有极高的社会效益和经济效益。

The plane bend belt conveyor is a special belt conveyor which uses flat conveyor belt to realize plane bending, it can also form space bending by performing vertical bending on convex and concave curved segment along with plane bending. It makes the conveyor produce an outward centrifugal thrust during operation to overcome the centripetal composite force of conveyor belt tension resulted from bending by taking certain special measures, thus ensuring the bend running of conveyor belt. This plane bend belt conveyor can realize the natural direction change of conveyor belt without the need of special conveyor belt with special structure.

The use of plane bend belt conveyor can realize the transportation line which cannot be realized on the original conveyor, or make the transportation channel greatly simplified which is very complicated to be realized with conventional rubber belt conveyor, thus lowering the investment for transfer station, reducing pollution points and equipment trouble points, and decreasing maintenance and operation personnel, etc. It can be widely used in fields as of coal, metallurgy, building materials, grains, chemical engineering, electric power, harbor, etc., and has very high social benefit and economic benefit.
