Have you seen our Heavy Duty isolator, HD Marine?
It is specially developed for heavy duty industry and marine applications such as suspension of propulsion engines, auxiliary engines, compressors etc.
HD Marine has a linear characteristic up to 10 mm deflection and is for the moment available in 3 different rubbers, ranging up to a static load of 6,5 ton but with the possibility to absorb double load short term. The isolator is also equipped with a displacement limiter ensuring limited movements when exposed to extra dynamic forces (such as roll, pitch and heave). It has been lab tested at Müller BBM for static and dynamic stiffness both vertically and horizontally.
