Excavator - type sleeper replacement machine is a kind of railway maintenance equipment. It is designed to meet the needs of railway track maintenance and emergency repair. This machine can be installed on various excavators with a tonnage rating of 6 - 13 tons. It can completely mechanize the removal and replacement of all kinds of railway sleepers, including cement sleepers, wooden sleepers and steel sleepers.
The excavator - type sleeper replacement machine consists of two main parts: the sleeper - changing clamp and the shield plate. With its large shield plate, it is very convenient and fast to remove the subgrade gravel around the sleepers that need to be replaced. Then, the hydraulic gripper is used to clamp the sleepers that need to be replaced and pull them out of the roadbed, and put the new sleepers into the roadbed under the rail. After that, the large shield plate is used to level the subgrade gravel evenly. In this way, the removal, replacement and leveling can be completed at one time, which truly realizes the multi - function of one machine, replaces manual labor and greatly improves the work efficiency.
The whole process is completely mechanized, which is reasonable and reliable. A special holding valve is installed on the clamp head to ensure that the clamping force remains unchanged even in the case of sudden drop in input pressure. The adjustable clamp end baffle ensures accurate work positioning. High - strength wear - resistant steel is adopted, which makes the machine light in weight. The digging depth of the large shield plate is adjustable, which makes the work more flexible. In addition, the structure of the railway sleeper replacement machine is compact, the operation is light and convenient, and the coordination is good. This machine has the characteristics of high operation and construction safety and strong practicality.
