Long-line system
Turnout sleepers as well as track sleepers are produced on long casting beds. The turnout sleeper which is uniform in cross section is particularly suited for this method; it is produced in a string and sawn to length as required. If the lengths per bed covering are known, mould end plates are used as well between the sleepers.
Due to its outline and dynamics, the track sleeper is posing special challenges to the manufacturers as regards detensioning. But this type of sleepers can also be profitably produced on long casting beds and convinces by a simple plant technology as against production in the carousel system.
For stressing track sleepers and turnout sleepers on the long-line system we supply
Casting bed equipment:
- Planning and in-depth advisory service for standard equipment and for special solutions
- Complete casting bed equipment (abutment anchor posts, transverse anchor plates, detensioning equipment, vertically adjustable supports, guards/safety devices, detensioning cylinders with support sleeves)
- Single-wire/strand stressing or multi-stressing
- Synchronized stroke display for detensioning equipment
- Anchor grips and couplers for strand and wire, threaded anchors or button head anchors
Basic machinery equipment:
- Easy to operate stressing jacks, optionally with automatic elongation measurement and logging (TENSAcontrol)
- Appropriate hydraulic pump units with jack lifting units, pneumatic tires and multiple connections
- Small and manoeuvrable hydraulic units for constricted space conditions
- Wire pushing machines and automatic wire pushing systems with hydraulic or mechanical steel cutters as well as strand uncoiling reels and wire cages
- Detensioning units for smooth force transmission for highest sleeper quality
- Force measuring units for stressing jack calibration and for stressing force control at the casting bed
- Cleaning lines for anchor grips
- Coiling drums and prestressing steel distributors
- Automatic and manual button heading equipment for prestressing wire
- Accessories and spare parts are available in the long term
We should be glad to provide advice on the following subjects
- Optimal process sequences
- Possible methods for your plant
- Technical system contexts of prestressing technology
- Reasonable combination of manual and automatic stations
