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
