Work principle: Once connected with power, the transportation system (available to users' demands) will make the elevating belt move from bottom to the top continually. Then it will get to the bucket that is fixed on the bucket belt and through which materials can be put into the mouth of the loading systems, then the materials will be transported to the elevator head. The elevator head was designed like a parabolic curve so materials can be reclaimed from unloading mouth. Meanwhile the empty bucket will move back to the elevator seat by the drive of bucket belt, once it is full of materials it will be elevated to the top again. Repeatedly like this it can meet the needs of vertical transportation. Features: 1) The machine has a beautiful appearance because of the small body. Although it only cost a little power, the transportation capacity is very large 2) The structure of transportation system is reasonable and reliable; the rubber that fixed on the head wheel can increase the fricative coefficient 3) The bucket is made of high strength plywood, so its life time is long and the volume is large 4) The bucket belt is made of nylon so the anti-tensile strength is strong, the extension rate is low and the life time is long 5) When the power is cut off, elevator will stop working, but materials won't fall back down into the seat of the elevator bottom, because there is a backspin system installed in the machine. Or if we are checking the machine when it is cut off, the belt will not move back so it can assure the worker is safe enough
