The robust construction of the cushymount is designed to withstand high impact forces, incorporating a built-in buffer to limit the vertical and horizontal movement of the suspended equipment, without the need for external limiting devices. Dissimilar stiffness rates in the two horizontal modes optimize the suspension system to avoid resonances with the main engine orders, while ensuring a high degree of vibration isolation during operation with rotational speeds as low as 500 rpm. The supports are approved by Lloyd's Register of Shipping and may be available with a height adjustment function for special circumstances.
