On April 4, 2021, during the Ching Ming holiday, most of the trains on the Shanghai-Nanjing intercity were delayed, and a large number of passengers gathered in the station. In response to this, the staff of the national railway hotline said that in the interval between Shanghai-Nanjing Intercity Suzhou Park and Yangcheng Lake, some trains were delayed due to equipment failures caused by kites entangled with the catenary. After rush repair by the maintenance personnel, the fault was resolved after one and a half hours.

Because there are mostly open areas along the high-speed rail lines, in the windy spring and autumn seasons, there are often kites and plastic films floating. Once the kites are hung or entangled on the railway track contact net, it is likely to cause the power supply equipment to malfunction, trip, and cause the train to stop urgently. , Interfere with the normal railway transportation order. In severe cases, it will also pose a threat to train safety. In addition to kites, balloons, sky lanterns, drones, and even light trash may force the stop of the high-speed rail.

The traditional method of cleaning external objects in the catenary is manual removal, but there are problems such as the need to block lines, long on-site operations, which may affect the punctual operation of passenger trains, and the removal of foreign objects in the catenary has become a pain point for railway operation and maintenance.

In response to this reality, Suzhou Usiland company has concentrated its R&D power to developed a smart laser clearance device suitable for railway operations on the basis of current product. It is small in size, high in energy, does not require preheating, and can be positioned within a few seconds. Remove foreign objects on the contact network to prevent floating objects from affecting the normal operation of the train.
