Construction work to replace railway sleepers

Currently, cars for replacing railway sleepers are modernized on the basis of excavators. The chassis is equipped with the front and rear lifting wheels, and at the front end, grips for replacing the sleepers and ballast cleaners are installed, which allows the replacement of the sleepers. Currently, the largest number of modernized equipment is based on excavators of the 75th model. There are two types of excavators modernized for cars to replace the sleepers.
The first type - the chassis is equipped with caterpillar chassis, which is popularly called a "two -wheel drive move", the speed of movement can reach 15 km/h, which makes such a machine a kind of "small train".
The second type - the chassis is equipped with a restrictive wheel for movement on rails, which performs the positioning function when replacing the sleepers to prevent the machine from the track.
