Sleepers Laying Machine VDH

The VDH 015 sleeper laying machine has been fully designed for the concrete twin-block sleepers. The care we brought to its design enables us to offer a very attractive export concept.

Attractive because, on one hand, our technology links quality, reability, simplicity, and on the other hand, through to the optimisation of the whole production process, which both lead to a major reduction of local production costs (equipment, raw materials, labour...)
Our technology is covered by several National and European patents.

Over this last decade we have sold and installed more than thirty units (sleepers laying machines and moulds) which have all met our customers requirements, to their highest satisfaction.

 
Operationnal data
  • Minimum output of 20 to 28 sleepers per hour (depending on the type of sleepers, type of fastening system and local production conditions)
  • Sleeper laying machine lifetime : 10 years
  • Mould lifetime : 500.000 sleepers
  • Easiness to fill the hopper and to control the production process
  • Installed power : 20 Kw max
  • Compact dimensions : Lxlxh = 3,5m x 4m x 4m. Approximative weight : 6 tons
  • Running on rail or swinging wheels, the VDH mobile is equipped with all the devices necessary to its operation.    Its is completely self-operating.
Technical advantages of a VDH- 015 laying machine
  • High adaptability to all kind of sleepers to be produced (networks [train, tramway, metro],  fastening [Pandrol, Nabla, Vossloh], rail gauge, sleeper dimensions)
  • Homogeneous and very resistant concrete thanks to the non-stop mould vibration and to the simultaneous mechanical compaction at the end of a cycle
  • Repetitive and constant quality thanks to the single mould process (one single mould can be adapted to suit different types of rail used in the same rail track)
  • Instant de-moulding and clearing of sleepers after 24 hours of in-line drying
  • Instant dimensional control gauging after de-moulding enabling all steel components to be re-used in cas of dimensional error
  • Millimetre-length precision due to the positioning of the reinforcements in the notches of the shoulders or inserts, as well as to the electromagnetic system of positioning and maintenance of the shoulders or inserts
  • Automatic control of the perfect alignment of the shoulders or inserts (solidarisation shoulder-netting and electromagnet)
  • Excellent mechanical resistance of the shoulders or inserts with double anchorage legs
 
Economic advantages
  • Production investments costs (turn-key plant), cheaper than any other type of control sleepers
  • Longer lifetime of twin-blocks concrete, produced according to our technology (over than 35 years)
  • Cheap raw materials can be used, ensuring the best sleeper's resistance values, thanks to the simultaneous vibrator and pressing process
  • Very easy machine to operate (only a few semi-skilled people required)
  • As far as the laying zone is concerned, a simple concrete slab is required - or even a plane stabilized zone (neither particular ground installation needed, nor other investment -  only provide water & electricity connections on the site)
  • Optimal use of the locally available materials (sand, aggregates, cement, steel wire...)
  • Old rails can be re-used to produce the tie-bars
  • No scrap sleepers due to the fully automatic production process
  • Sleeper production does not require heating during concrete curing. The raw materials are common. No additives are requied to the mix
  • Easy moving of the machine (on rails or wheels) on the installation site (significant transportation cost reduction)
  • In summary, the twin-block concrete sleepers produced according to our technology link the highest performance values with a simple and low cost process of manufacturing
