From small pumps and generators to entire buildings; VISOTECH can treat all vibration issues. Backed by GERB, the German experts in this field, VISOTECH now makes these latest technology high quality systems available to our Australian and New Zealand customers.
Owing to their high-speed rolls, rotary printing presses cause vibrations In the machine itself as well as in its foundation. Therefore, in many cases right up to the present a large concrete foundation is foreseen which can be placed on piles should the subsoil be unsatisfactory.
Pipework dampers are frequently used for the protection of piping systems and other components in power plants and industrial facilities. GERB pipework dampers are highly effective viscoelastic elements, well proven in numerous installations. Already in 1951 Viscodampers® were patented for pipe applications.
GERB Floating Slab Systems are successfully installed in tunnels, above ground, and on elevated rail tracks.
The most common use of Visotech GERB vibration isolation solutions in Australia and New Zealand is with plant and equipment. Eliminating these vibrations is important both for the health and safety of workers near these machines, but also for the machines themselves.
Wide span structures such as bridges, stairs, and roofs, as well as tall, narrow structures such as chimneys, antennas, masts and buildings, can be easily excited to high vibration amplitudes in their first or higher eigenforms. Excitations can be caused by wind forces, pedestrian traffic, machinery or earthquakes. Natural frequencies and damping are typically low for these structures. With GERB tuned mass dampers (TMD), these vibrations can be easily reduced.
With the Newcastle earthquake and the more recent Christchurch event in mind, Australian and New Zealand architects and engineers are taking earthquake protection of infrastructure and buildings very seriously. Visotech can help with very the design and supply of specific and customised earthquake protection systems.
The isolation of entire buildings from outside vibrations is a very specialised field of expertise. Visotech Australia/GERB have been working on such projects for many years now, all over the world. We can work with architects and engineers to design and supply vibration isolation systems customised to each project's exact requirements.
Large gas and diesel engines are used for many purposes, i.e. trains, ships and for local power generation. In all cases, foundations for these engines must be both economical and effective. Elastic support of this equipment meets these requirements.
