Control any type of shaking caused by forces such as strong wind, earthquakes, and vibrations triggered by walking.

We offer the best proposition according to the application, installation conditions, and customer needs. The equipment can be classified into two categories: “passive type” and “hybrid type.” The hybrid type has powered components for motorized control.

Vibration control system for high-rise buildings

The shaking of a building caused by strong winds or aftershock is reduced to improve livability.

High-rise buildings today are built with soft structures to “yield the strength” of earthquakes. Although, these safe “vibrations” may lead residents to feel unsafe or unpleasant. Our vibration control systems reduces these vibrations to secure safe and comfortable spaces.

Vibration control systems for Observatories and Airport traffic control towers

Higashiyama Sky Tower, Nagoya
Kansai International Airport

We propose high-performance equipment that can be installed in limited space.

Our vibration control system is available for observatory buildings which becomes a landmark for its area, and for airport traffic control towers checking all the airplane landing and departures.

Vertical vibration control system for floors

Illustration of Vertical vibration control system for floors

Vertical vibrations on the floor caused by walking or an earthquake are reduced.

Our device, confirmed by affluent delivery records and superior technologies, can be applied to wide range of situations as a countermeasure for walking and traffic vibrations and also for earthquakes.
MHI Machinery Systems provides vertical vibration control system which responds to various vertical vibration in new buildings as well as existing buildings with experienced analytic and research technologies.

Vibration control systems for industrial chimneys and wireless communication towers

The shaking of a steel structure due to winds is controlled to improve fatigue strength.

A vibration control device is introduced into a stack or a steel telecommunications tower to reduce wind response, dampen seismic force, and prevent electromagnetic interference. Structural members can be protected from fatigue damage caused by wind response.
