Introduction
Vibracon®chocks are permanent, strong and re-usable machinery mounting chocks for all
types of rotating or critically aligned machinery. Vibracon®chocks are mechanically stiff
chocks that make accurate mounting simple and quick. The Vibracon®advantages are
elimination of the trial and error alignment process characteristic for the “mill and shim”
method and adjustability during the life cycle of the machinery.
The Vibracon®chock has many configurations and material options to satisfy technical
concerns, in end user environments and production line costs. All Vibracon®chocks include
the spherical top plate and mating middle section. This self leveling configuration
accommodates the angular differences that are inherent with mounting surfaces. The height
adjustment feature has the greatest range in the industry, which makes the Vibracon®chock
easy to install.
Vibracon®chocks are the most economical means to establish a perfect mounting plane. The
Vibracon®advantage is the capability to perfectly create the mounting plane within minutes
and repeatedly for Production or Service Managers and Accountants.
In this manual we will inform you about all facts of the Vibracon®. If you have further
questions or if you need additional information, please remember The Machine Support
Group is a 24/7 organization. Please don’t hesitate to contact one of our offices as
mentioned below.

2.1 How to select the right Vibracon®chock size?
To get an indication which size of Vibracon®should be used, the following parameters will
give you an impression:
•What is the size of the bolthole in the component bed plate?
•What is the minimum distance (pitch) between two adjacent holes?
The type indication of Vibracon®is related to the foundation bolts for which they can be used.
For instance the Vibracon®SM30 is developed to be used in combination with a hexagonal
bolt M30 but it is also possible to use one size of bolt diameter bigger, in this example a bolt
M33.
2.2 How to get a Vibracon®chocking proposal free of charge?
As a part of our service, Machine Support offers you a free of charge calculation proposal for
the mounting of your component. To prepare this calculation we need information concerning
the component, the available chocking height and some information concerning the
foundation.
The fastest way to receive a chocking proposal for your application is to fill out one of the
appropriate datasheets (APPENDIX 1). The datasheets can also be downloaded from our
website www.machinesupport.com we ask you to send the completed datasheets by e-mail
to:
[email protected]
The used calculation software is approved by the Classification Societies involved for marine
applications. On request Machine Support will make contact with the OEM to support you
with getting an agreement on the chocking proposal.
Normally you will receive, within one day, a calculation as mentioned in APPENDIX 2.
A full proposal consists of four sheets:
•Report of all information related to the selection of the chock, including operating
forces on the chocks plus foundation hardware information;
•Illustration of the top view of the component that shows the location of the chocks, the
position of the positioning and / or collision chocks and the fitted bolts (if required);
•Illustration of the cross section of the foundation bolt in which the clamping length and
foundation bolt are specified;
•Illustration of the cross section of the fitted bolt, if required, in which the clamping
length and fitted bolt are specified.
Machine Support, upon request, will submit our report to the involved Classification Society
for approval. Costs for this service are on an as negotiated and per event basis.

2.3 How to order Vibracon®chocks?
In the Vibracon®brochure (see chapter 1) you will find an overview of the standard elements.
If you have a specific component which has to be chocked and the standard elements will
not fit, please don’t hesitate to send in your demands and we will find out if we can provide
you a proper solution.
Based on the unique article numbers the chocks can be ordered by fax, mail or e-mail. As
soon as we have received your order we will send you an order conformation in reply.
Vibracon®chocks are always on stock at Machine Support in the Netherlands. However, it is
recommended to check the delivery time before ordering. Our local dealers of the elements
also have some elements on stock.
A list of all distributors is available on the website from Machine Support:
www.machinesupport.com
2.3.1 The Original
Vibracon® SM chocks are machinery mounting chocks that are easily and accurately
adjusted. The chocks accommodate up to a 4° angular difference between machine and the
mounting base without expensive machining of the base or extra work of installing epoxy
resin chocks.
The self levelling capability combined with the height adjustment feature eliminates the
possibility of a soft foot in the production line and for the life cycle of the machinery.

2.3.2 The Low Profile
The Low Profile chocks offer an economic solution for repair projects or fixed design systems
where expensive milled chocks, shims or epoxy resins were applied. The Vibracon®SM Low
Profile configuration addresses those applications where the chock height between the
foundation and component has been established by the previous design. Most of the other
chocking methods are time consuming and do not support the life cycle needs of the
machine owners and installation activities on a tight schedule. A variety of adjustment tools
for confined installation spaces is available.

2.3.3 The extended Vibracon®Original and Low Profile
It can happen that the maximum element height is not sufficient to fill up the gap between the
foundation top plate and the bed plate of the component. In that situation it is possible to
introduce a so called additional bottom ring to extend the maximum height of the Vibracon®
Original and Low Profile chocks. This ring will be mounted between the base plate of the
chock and the top plate of the foundation. As an alternative for the additional bottom ring
Machine Support can also provide Vibracon®extended bottom rings.
As a rule of thumb, the height of the chocks should not exceed the diameter of the elements.
For instance the maximum height of a Vibracon®SM30, with a diameter of 140 mm, should
not exceed a chock height of 140 mm.
