Storm brake / rail clamp type VZFH-HVZ, with lifting and positioning function
About the product
Patented: Storm brake / rail clamp with integrated lifting and positioning function.
- With integrated lifting function
- No contact to the rail during crane travel / Therefore no wear on clamping jaws and guide rollers during crane travel
- No guide rollers for guidance the clamp on the rail during crane travel
- Lateral positioning function for lowering the clamp system -(patented pending system)
- Particularly suitable for fast moving crane systems
- Particularly suitable for transverse travels / cross-runs
- Restraining / holding forces up to 640 kN per clamp
- Self acting in case of power failure
- MADE IN GERMANY
VZFH-HVZ is an upgrade version of standard rail clamp type VZFH.
- Closing by spring force with toggle lever system – adjustable by throttle
- Opening by hydraulic-cylinder (Hydraulic power unit is integrated)
- Hand pump for emergency operation (manual) is supplied (standard)
- Automatically closing function in case of power failure
- No loss of restraining / holding force due to toggle lever transmission resulting from e.g. wear of clamping jaws (permissible measure)
- Limit switch position control system “Clamp open”, “Clamp close” and alarm signal “worn clamp jaws”
- Position control switch for “Clamp is in lifting position / Crane travel is possible
- Vertical movement compensation of + 40 mm up to – 20 mm
- Lateral compensation for rail misalignment of ± 25 mm with integrated lateral guidance system during lowering
- During crane operation all parts of the clamp are positioned above the rail system / Therefore no wear of any components during crane operation
- Guide rollers for guide the storm brake on the rail as used at standard type VZFH will not be integrated into type VZFH-HVZ (wear reduction, reduced maintenance and follow-up costs)
- Particularly suitable of fast moving crane systems(over 300 m/min)
- Strongly reduced maintenance / follow-up costs
- No contact to the rail during crane travel
- No loss of restraining / holding force due to toggle lever transmission (resulting e.g. wear of clamping jaws)
- Special flange mounting
- Special construction
- Special painting of housing (Please specify RAL color)
- Crane systems
- Offshore / Ship
- Steel industry
- Railbound hall roofs / gates
