Cushymount™ ’K’
Features/Applications
The Cushymount ”K” Series Mountings have been developed primarily for the suspension of medium speed diesel units used for marine main propulsion and auxiliary power generation applications, but may also be considered for rail locomotive traction power units, gas turbines and compressors.
The load capacity range of the mountings extends from 20kN to 80kN with effective deflections of up to 10mm on the larger mounting. The dissimilar stiffness rates in the two horizontal modes enables optimisation of the suspension system to avoid resonances with major engine orders whilst providing a high degree of vibration isolation when operating with rotational speeds as low as 500 rpm.
The robust construction of the mount is designed to accommodate high shock forces, incorporating an integral buffer to limit vertical and horizontal displacement of the suspended equipment without the need for external limiting devices.
The mountings carry Lloyd’s Register of Shipping type approval and for special requirements can be made available with a height adjustment feature.
