VZH Storm Brake / Rail Clamp – Fully Hydraulic

Hubner Australia is proud to offer the Type VZH Storm Brake / Rail Clamp, designed and built by Römer Fördertechnik GmbH (RFT Germany). Moreover, this clamp delivers dependable and fail-safe holding for cranes or rail-bound machines across Australia and New Zealand.

Key Features and Benefits

  • Made in Germany – RFT ensures high safety and quality standards.

  • Hydraulic closing and opening – It closes and opens solely via hydraulic power, offering reliable and smooth operation.

  • Strong holding force – Depending on version, each clamp delivers up to 256 kN, and with optional upgrade, up to 623 kN.

  • Fail-safe option available – You can choose a version with a pressure accumulator that closes the clamp automatically in a power loss.

  • Limit switch monitoring – Built-in sensors track whether the clamp is open, closed, or worn, helping you stay informed and safe.

  • Compensates for rail misalignment – Even if rails are slightly off, the clamp adapts to ± 15 mm sideways; more if needed.

  • Guidance in two positions – The clamp is usable in both vertical and horizontal designs, matching your setup needs.

 How It Works

First, hydraulic oil powers the clamp to open and close. Then, in case of power loss, the pressure accumulator acts and ensures the clamp closes automatically—unless you choose a non-self-closing version. Finally, the limit switches track the clamp position to alert operators about any issues.

 Typical Uses

This clamp is perfect for:

  • Overhead, bridge, and gantry cranes

  • Shipyard and offshore rails

  • Roof gates in rail depots

  • Heavy-duty steel, mining, or wind-industry gear

  • Any system needing safe, stable holding in storms or power failure

 Versions & Options

You can choose between three versions:

  1. Hand-pump only – manual, not automatic at power loss.

  2. Hydraulic unit – powers opening/closing, but no auto-close on power loss.

  3. Hydraulic unit + accumulator (VZH-A-S) – auto-closes during power loss.

Moreover, you can add:

  • Custom flanges to suit mounting needs

  • Special RAL paint for environment protection

  • Additional limit switches or alarms

  • Higher force options (up to 623 kN)
