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:
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.
