Storm Brake / Rail Clamp Type VZFH-HVZ

At Hubner Australia, we’re proud to offer the VZFH-HVZ Storm Brake / Rail Clamp from Römer Fördertechnik (RFT Germany), designed with patented lifting and positioning functions to boost crane safety across Australia and New Zealand.

 Key Features & Benefits

  • German-built reliability – Made in Germany to the highest standards

  • Patented lifting design – It lifts clear of the rail during crane movement, eliminating wear and tear

  • Automatic closing on power loss – Spring-loaded toggle system ensures clamp locks without power

  • Height and lateral adjustment – Compensates ±40 mm vertically and ±25 mm sideways for rail misalignment

  • High holding capacity – Up to 840 kN per clamp, ideal for high-speed cranes
