GMT supplies rubber and rubber to metal bonded elements to reduce and eliminate unwanted vibration and noise in all kinds of construction equipment. High-frequency loads require elastomer qualities specially adapted to this application.
These applications typically have very high levels of mechanically induced vibration and impact stresses which have to be isolated. The large product range of GMT mountings, which have been especially developed for this purpose, include
- elastomers for vibratory hammers
- buffers and rails for vibrating drum rollers and vibration compaction plates
- buffers for hand grip
- cab suspension elements
- engine bearings / aggregate bearings
- axle bearings
In areas like the steering mechanism bushes, springs and steering rods are mainly used to achieve the desired isolation. The use of maintenance free mountings with a long service life is the economic choice for such like applications. Our In-house compounding specialists have the expertise to support customers when selecting compounds used for these applications, which can be improved for good oil-, grease- and / or frost- behaviour and physical properties.
When used for the isolation of vibrating drum rollers and vibration compaction plates the heavy duty rubber mounts are subjected to both shear and compression loading. GMT elements provide isolation of the vibrating drum or plate, hence preventing fatigue and wear on moving parts. Great demands are made on the mountings which are exposed to high loads and extreme environmental conditions.
For the suspension of the vehicle cab we recommend the use of GMT cone mountings. The special design of these mountings provides for different stiffness in the three main axes. This offers a high comfort for the driver and at the same time a safe guidance of the cab is provided.
