Sleeper changer and ballast remover

Diesel Fuel Heater Hardfacing


The Sleeper Changer and Ballast Remover SWG 10 allows to change sleepers and remove ballast underneath the installed track.

Individual resleepering as well as continuous resleepering is possible.

For continuous resleepering, the sleepers will be replaced as well as the old ballast removed and the formation will be levelled, all in one go.

In continuous resleepering the output can peak to approximately 1 sleeper per minute.

For the

replacement of individual sleepers, the ballast blade of the SWG 10 allows to prepare the sleeper bay prior to installation of the new sleeper.

Output in single sleeper replacement is depending on sleeper and site conditions.


All types of sleepers can be handled by the NEWAG SWG 10 sleeper changer, including bi-block sleepers.


The unit can be powered by a hi rail road cum rail excavator with a machine weight of 12 – 15 t.

The excavator must be equipped with 3 independent hydraulic circuits fitted to the jib of the excavator.


The sleeper changer and ballast remover can be employed for the following jobs in trackwork:


1. Continuous resleepering and ballast removal Sleeper changer with buckets and sleeper pincer

2. Single sleeper replacement Sleeper changer with pincer, however without buckets

3. Ballast removal without resleepering Sleeper changer with buckets and sleeper pincer


Working method:


1. for continuous resleepering

- Lifting of track by winches or track lifter

- Removal by means of the pincer of first 4 – 5 sleepers sideways through ballast shoulder

- Vertical pivoting of sleeper changer 90° into ballast removal position, creation of a work pit. As soon as pit is formed, the track does not require lifting any more. The pit progresses as work advances.


From now on there is a cycle which proceeds as follows:

- Pick up and pull back of the next old sleeper at the far end of the pit by means of the sleeper pincer for about 2 m,

- Turning of the sleeper by rotator built into the sleeper pincer horizontally by 90°,

- Lifting off the sleeper through the middle of the track, pivoting sleeper changer 90° vertically into ballast remover mode,

- Removal of the ballast by ballast blade and fitted ballast buckets,

- Disposal of the old sleeper,

- Picking up of new sleeper,

- Turning new sleeper horizontally into the track and fitting of sleeper at the correct spacing to the already (re)installed sleeper at the nearside of the pit,

- Driving forward to the far side of the pit,

- Picking up of the next old sleeper and repeating the described cycle.


2. for replacing single sleepers

- Lifting of the track by winches or track lifter,

- Pick up of the old sleeper and pushing out sideways through the ballast shoulder by means of the sleeper pincer,

- Disposal of the old sleeper,

- Pivoting of the sleeper changer 90° into ballast blade mode,

- Levelling of the sleeper bay before insertion of the new

Sleeper,

- Pivoting back of the unit in sleeper changing mode, picking up of new sleeper and insertion sideways into track into prepared sleeper bay.


3. for ballast removal without resleepering

- Lifting of track by winches or track lifter,

- Removal by means of the pincer of first 4 – 5 sleepers sideways through ballast shoulder,

- Vertical pivoting of sleeper changer 90° into ballast removal position,

- Creation of a work pit.


As soon as pit is formed, the track does not require lifting any more. The pit progresses as work advances.


From now on there is a cycle which proceeds as follows:

- Pick up and pull back of the next old sleeper at the far end of the pit by means of the sleeper pincer for about 3 m,

- Repositioning and fastening of the sleeper at the nearside of the pit,

- Vertical pivot back into ballast removal position,

- Excavation of the ballast and levelling of formation,

- Pick up of the next sleeper at the far end of the pit,

- Pulling back of the sleeper and installation at the correct spacing to the last mounted sleeper at the nearside of the pit,

- Repeating the same cycle again and again.
