Brief Introduction The kinds of industrial transfer cars trolleys, which is powered by low voltage railways. It makes the AC electricity power is transformed into AC 36v three-phase and are respectively connected to the three rails. Then the industrial transfer cars trolleys conduct the AC 36v on rail into the electrical appliance box at the bottom of the trolleys. And then the AC 36v is transformed into DC 36v to control the DC motor. Use this principle to make the industrial transfer cars trolleys start, stop, go forward and backward and adjust the speed and so on. This series industrial transfer cars trolleys have strict requirement on the construction of the railways which need to be insulated. In the transition of voltage, transformer is required to convert high voltage to low voltage. When running distance is more than 70m, you need to increase the transformers to make up the voltage which has been lowered Parts Show Trolley Frame The frame is two longitudinal beam, several beams with steel panel welded together, which adopts box beam structure according to the crane principle and combined with the design of the rail wheels. Its main feather: large load bearing, little table deformation, long service lifetime. Rail Wheels About the industrial transfer cars trolley's wheel, it is single rim of corner case, the material is ZG55, or can be customized as per your demand. It can improve the load capacity and install easily. And the rail wheels are manufactured and assemblied by ourselves. Lifting Hole The lifting hole are installed on the industrial transfer cars trolleys for convenient transporting. Especially, it can be lifted and moved after the structure finished. What's more, it makes the appearance more delicate and beautiful.
