The AMC-MECANOCAUCHO® Hi Sec height-adjustment system is designed for applications requiring precise engine alignment together with the ability to withstand high thrust loads and dynamic forces.
Its reinforced construction and oversized central nut make it particularly suitable for marine propulsion engines, where the mounting system must maintain accurate positioning whilst transmitting the forces generated by the propulsion system.
The Hi Sec system is zinc-plated and chromated in accordance with DIN 50961 / ISO 2081, providing effective protection against corrosion and making it suitable for demanding marine and industrial environments.

DNV rules for ships/ High Speed light craft, Issue Jan 2016 Point 4 Chapter 3 Section1 F202, establishes that standard height adjusters are not acceptable for leveling, due to cyclic bending moments that the studs and bolts are subjected to. This is the reason why leveling of mounts using shims beneath the mounts is the only recommended method for leveling.
AMC-MECANOCAUCHO shares also this method and that is the reason why AMC-MECANOCAUCHO® Shims have been developed. In order to achieve a fine leveling HI-SEC height adjusters allow a final precise adjusting with security.
