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 840 kN per clamp
  • Self acting in case of power failure
  • MADE IN GERMANY

  • 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
  • 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
