A company in Wuxi, Jiangsu, ordered a battery powered on rail transfer trolley in our company. The company is doing wood processing. The flat car is ordered to carry the wooden board. We have fixed brackets on the flat car. There are rollers on the bracket. The roller can be rotated automatically, the plank can be transferred to the middle of the flat car along the roller, and then the board is transported to the processing room. The customer said that this flat car not only saves manpower handling but also saves the car transportation. It is more than one car and said that it will add two more.
