VZM Storm Brake / Rail Clamp – Manual Operation

At Hubner Australia, we offer the VZM Storm Brake / Rail Clamp from Römer Fördertechnik GmbH (RFT Germany) across Australia and New Zealand. This manually operated clamp secures cranes and rail‑guided machines—especially during storms, power loss, or emergency stops.

 Key Features and Benefits

  • Made in Germany – Crafted to high standards to ensure long-lasting and safe use

  • Simple manual control – You can close or open the clamp by hand, giving clear operational control without power .

  • Strong holding force – It prevents movement with up to 100 kN of force per clamp

  • Climb‑up lever mechanism – Moreover, it includes a lever that lifts the clamp off the rail when opening, reducing wear

  • Position sensors – You can monitor whether it’s open or closed using built‑in limit switches

  • Rail misalignment tolerance – The floating housing allows ± 7 mm lateral and up to ± 25 mm with rolling guides or hand lever positioning

  • Guided sliding housing – Additionally, the unit includes rollers or a hand lever for horizontal alignment, so the sides remain clear

 Technical Details

First, the clamp closes manually using a hand wheel or lever. Furthermore, when you open it, the lever lifts the clamp shoes clear of the rail, and rollers or a guide lever help reposition it if the rail is misaligned. Then, limit switches confirm the open/closed status for safe operation.

Specifically, it features:

  • Manual closing/opening via handwheel or lever

  • Clamping force up to 100 kN per clamp

  • Floating housing with ± 25 mm rail misalignment compensation (or ± 7 mm without guides)

  • Limit switch monitoring for open and closed positions

 Ideal Applications

Because it’s fully manual and reliable, VZM is a great fit for:

  • Crane systems in ports, factories, warehouses

  • Rail‑mounted hall roofs and entrance gates

  • Mining and material‑handling systems

  • Offshore or ship cranes

  • Any setup needing a fail‑safe, non‑powered storm brake

 Options & Add‑Ons

To tailor it to your needs, VZM offers:

  • Limit switch kit: Provides open/close status

  • Custom flange mounts: Fit to your specific structure

  • RAL paint selection: For branding or corrosion resistance
