In order to meet the needs of rapid, safe and efficient railway transportation, the track maintenance sections of railway bureaus need to replace the invalid concrete sleepers frequently to ensure the traffic safety, which is one of the important work contents of railway speed increase. The replacement of sleepers can be carried out by railway sleeper changing machine. The railway sleeper changing machine can be used to install and replace the sleepers, and can also clear and arrange the stones that hinder the work. At present, the way of replacing sleepers by railway departments is still mainly manual work. Manual replacement of sleepers is labor-intensive, slow and inefficient. In order to speed up the replacement, even if one sleeper is replaced, four or five people are required to complete a skylight point. In order to improve the speed and efficiency of railway sleeper replacement, railway sleeper changing machine can be used. Its function is to install and replace sleepers. The replacement of sleepers is carried out in the interval time of train operation. Too few operators will affect normal operation due to too slow speed. However, the cost of manual replacement of sleepers is high and the efficiency is low. In order to solve the problem of high cost and low efficiency, it is necessary to use sleeper replacement machinery to replace manual operation. The railway sleeper changing machine can install sleepers in the initial stage of railway construction, or clean the stones beside the sleepers and replace the sleepers in the later stage of construction.
