Overview Rail Clamp Systems
- High durability
- Position of clamp remains unchanged in case of power failure (fail-safe)

Rail Clamp electro-hydraulical
(PDF, 2.32 MB)
Operation:
- Closing through spring force
- Adjustable throttle (time delay 3 - 120 sec.)
- Opening through hydro-cylinder und hydro-aggregate incl. emergency hand-pump in case of power loss
- With power loss the rail clamp closes automatically (fail save)
- Holding force per rail clamp with μ = 0.25 or μ = 0.4ZWA
Special Features:
- Automatic rail clamp; horizontal movement ± 25 mm and vertical movement ± 20 mm. Two idlers inside the clamp housing guide the rail clamp on the rail
- No loss of clamping force resulting from jaw wear because reduced spring force is compensated by increasing the toggle lever transmission
- Limit switch controls the position of rail clamps "clamp open", "clamp closed", "jaw wear"
- Pressure switch in hydro aggregate redundant to mechanical limit switch at the clamp car
- Holding force per rail clamp with μ = 0.25 or μ = 0.4 according to DIN 15019 Part 1
- Exchangeable clamping jaws
- Emergency hand-pump in case of power loss
- Electro-installation complete to terminal box on the clamp housing
- Hydraulic system, hydro-aggregate and hydro-cylinder are ready for operation, hydraulic oil is included
- Clamp housing idlers hardened
- ZWA car support rail VHS for maintenance free operation of the rail clamp is included
- Aluminium cover is protected from environmental influence when it is completely closed. On demand the sides of the cover can be turned around, so that 2 big vertical openings develop
- 160 μm paint with four layers standard
- Rapid interchangeability of the units , like hydro-cylinder and hydro-aggregate
