Hydraulic mounts

Hydraulic mounts combining elastomeric elasticity and hydraulic damping to optimise vibration isolation and equipment movement control.

The AMC-MECANOCAUCHO® hydraulic mounts combine the function of an elastomeric spring and a hydraulic damper in a single unit, providing both effective vibration isolation and improved control of equipment movement.

Their design incorporates a hydraulic fluid whose movement within the mount generates additional damping. This technology allows the stiffness and damping characteristics to be adapted to the dynamic requirements of the application and helps reduce excessive movement, particularly during transient conditions and when passing through resonance.

The internal construction combines metal components bonded to the elastomer, ensuring the integrity of the hydraulic system while providing resistance to high dynamic loads and shocks and maintaining excellent durability.

These mounts are particularly suitable for engines, mobile machinery, generator sets and equipment subjected to vibration, shocks or load variations, where a combination of effective vibration isolation and high damping is required.

Technical characteristics

The AMC-MECANOCAUCHO® Hydraulic mounts have an interlocking metal component that provides fail-safe protection for mobile applications. This device limits excessive vertical movement when the mountings are subjected to shocks inputs.
The metal parts are suitably thick and robust to withstand Off Road vehicle application shock inputs and also have an outdoor anti-corrosive treatment fully compliant with RoHs

TECHNICAL ADVICE FOR FOPS ROPS APPROVAL

AMC-MECANOCAUCHO's technical department will be pleased to offer you advice on correct installation procedures to achieve FOPS/ROPS tests approvals.

These pictures show a typical traction test on rectangular hydraulic medium mount subjected to loads up to 4 Tons without destruction of the part. For more information on this topic, please contact our technical department.

Operation and Assembly

A hook wrench should be used in the slots to avoid the rotation movement of the rubber.

Advantages

Improved isolation

It offers improved isolation compared with conventional anti-vibration mounts of similar geometry.

Superior damping that reduces amplification and controls movement

The superior damping enhances equipment stability: when passing through resonance during start-up and shutdown, energy is absorbed, resulting in reduced amplitude.

High robustness in dynamic applications for improved durability

These mounts offer enhanced robustness and are designed to withstand extreme load peaks. They are especially recommended where good durability is required in demanding applications.
