Trelleborg’s industrial anti-vibration solutions operation has launched two new marine engine mounts – the high deflection (HD) Cushyfloat and the mini HD Cushyfloat – to provide improved vibration isolation and passenger comfort on marine vessels.
Based on Trelleborg’s most popular marine engine
mount, the Cushyfloat, the new solutions have been purpose-designed to alleviate
excessive vibrations caused by an increase in engine power on lightweight hulls.
Specifically, the new HD Cushyfloat is specially
developed using a unique rubber compound, which increases its ability to
provide improved vibration isolation, especially when travelling at low speeds
due to harbor restrictions, for example.
Bill Mortel, Director – Materials and Technology at Trelleborg’s industrial anti-vibration
solutions operation, says: “When operating at low speeds, the level of unwanted
vibration caused by the boat engine increases. This creates a more difficult
environment for a standard mount to isolate those vibrations. As such, a
specialist solution was required and so our HD Cushyfloat was born.”
Vibration is passed through the mount to the rest
of the vessel, the amount of which depends on how well the mount isolates the
vibrations. As such, the rate at which the mount deflects under the various
landing conditions of a marine engine is critical to ensure a smoother, quieter
ride for passengers and workers onboard.
Mortel continues: “Vertical and lateral buffering
within the HD Cushyfloat’s design limits the movement of the engine in tough
service conditions. Similarly, it has an interchangeable footprint with
existing mounts, which makes retrofit easy and trouble free. Furthermore with an
in-built deflection gauge as standard, the installation and alignment of the
engine is simplified.”
