Reduced unsprung mass, reduction of vibration and noise, easy replacement of wheel tyres
GHH proposes a wide product range of rubber-sprung wheels, based on the experience of more than 75 years and 120’000 wheels supplied in very different applications, from light rail to heavy haul locomotives:
- The SAB V-Wheel family (V15 - V30 - V60).
- The SAB Resilient Disc Wheel.
- The VUT Wheel.
Running comfort, for the passenger, the resident, the vehicle and its track
Proven by field measurements or positive customer ratings. GHH resilient wheels provide a very efficient reduction of shocks and vibrations. With their low radial stiffness, the SAB Resilient Wheel or the VUT wheel can replace a primary suspension or accommodate specific bogie designs, e.g. direct motor drives.
Key benefits of GHH solutions
Tailor-made solutions, because each project is unique. Specifics like: small diameter, high wheel load, thermal impact from block brake are adapted to each project.
Maintainability, because service costs must be minimal
One common feature for all our wheels: a split design. Three steel parts: a wheel tyre, a wheel body and a wedge ring. In between, some pre-stressed rubber elements: rubber pads, or, alternatively, one rubber ring or two rubber rings. Result: a very easy replacement of tyres and rubber elements, with only conventional tools.
GHH resilient wheels decrease rolling noise and squealing noise in curves. In case of additional requirements, GHH proposes customised noise absorption systems, like rings, absorbers or shields, mounted on the wheel tyre.
Key benefits of GHH solutions
Tailor-made solutions, because each project is unique. GHH designs its solution following the specific requirements of bogie, drive and brake modules. Meter or standard gauge, restricted spaces, high loads or severe operating conditions. Bogie or running gear, wheelsets or independent wheel axles. GHH provides the solution.
GHH is the partner of the manufacturers of low-floor Light Rail Vehicles
From driven wheelset to swivel-mounted independent wheel unit, high tech for low-floor.
From development and engineering to production and assembly, the complete wheelset system is the core of our expertise.
Our products fulfil the requirements of any specific vehicle platform:
- Driven and non-driven wheelsets
- Independent wheel axles with cranked axles
- Independent wheel unit with or without swivel-mounted wheels
The systems are supplied with resilient wheels of the extensive product range of GHH for a significant reduction of noise and vibrations.

Ready to install, because system engineering is our strength.
GHH develops and delivers a complete solution, from wheel and axle to bearing system and speed sensor, ready to install in the bogie or running gear.
Reliable design, reduction of maintenance costs.
A robust and service-proven design, a strict respect of manu-facturing quality and a thoroughly studied maintenability ensure low costs for operation and maintenance. GHH offers tailor-made service packages, from operation consulting to in-house service.
Attractiveness and comfort, low-floor as a key feature.
The systems of GHH provide vehicles with the improved accessibility of low floor. Resilient wheels of GHH contribute to a significant reduction of rolling noise and, more impressively, squealing noise. For passenger comfort, for residents quality of life and for the environment.
