RotaChock Introduction The RotaChock is an adjustable, self leveling and reusable equipment mounting chock. The RotaChock is
a blend of engineering and years of field experience to produce a strong, stiff and elegant device to end
machinery softfoot.
Machinery Mounting Solutions’ Philosophy
Strive to design and manufacture the best chocking solution for our customers. Using the parameters
provided by our customers we create technical and economical resolutions to a fundamental and core
element of machinery installation ‐ chocking. Chocking solutions can take a variety of configurations
and materials and we exploit our comprehensive experience with machine installations for the
equipment stakeholders. Primarily, we consider mechanical chocks as the best life cycle decision for
rigidly mounted machines because of the adjustability characteristics and reusability features.
Our approach is to partition chocking into two needs either new construction or retrofit. For new
designs, we have a standard brochure that illustrates our ease of installation and economics to suit the
end users environment. For the retrofit and fixed design markets, we use our core elements and create
solutions for the application.
Chocks
Chocks, liners and shims are placed between equipment and its foundation. Chocks by any other name
or of the many configurations and materials which are used throughout industry have two simple goals:
create a flat mounting surface for the equipment and transfer of energy from the machine to the
foundation. The history of chocking began with milled foundations and fitted chocks which gave way to
shims and poured epoxy chocks. All these techniques are good practices but at Machinery Mounting
Solutions with experience in all these techniques we have developed the RotaChock with attributes that
achieved the basic goals stated above plus we add reusability attributes that are unmatched in the field.
RotaChock Details
The RotaChock is a mechanical chock. The core technologies are from diverse backgrounds of
applications that are time‐tested and standardized under a variety of technical organizations and
societies. We package these successful techniques differently and we made the RotaChock the easiest
chock to install and reuse.

The following illustration exhibits some of the innovations of the RotaChock:
Lenticular Top Part – at 4 degrees, the largest angular
difference in the market
Adjustment Slots to accommodate a variety of tools
ANSI Compression Buttress Threads for maximum strength,
stiffness and adjustment range for the material selected.
Plus, ease of installation in all rugged environments.
Surface: load rating ratio that is the best in the market
We have blended technologies to evolve mechanical chocking and we proudly present a technically
superior product. The RotaChock can be provided in a variety of configurations to suit the application.
We manufacture the RotaChock in a variety of materials to suit lifecycle environments.
The technical approach for development of the RotaChock was to create the highest load rating viable
while using the lowest yield strength material required by industry (316 Stainless Steel per API
Guidance). Our approach means the normal carbon steel and alloy steel chocks have an even greater
margin of safety over and above the stated chock ratings. The RotaChock is easy to install and can be
adjusted with a variety of hand tools usually available in the field. Also, the RotaChock needs to be
reusable. The ability to readjust the mounting plane to accommodate modularity of machinery, settling
of the foundations and machine wear is an essential element to lowering life cycle costs of machines.
Another RotaChock innovation is the experimentation and implementation of a process to inhibit rust of
normal steel chocks. Stainless Steel 316L is an excellent and required material for highly corrosive
applications but it comes at a price. At Machinery Mounting Solutions with a consistent objective to
improve our products, we incorporated a molecular diffusion process for carbon steel and alloy steel
chocks. We call the process Anti‐Corrosion Enhanced – ACE! The process developed many years ago
primarily for the automotive industry has been adopted by oil and gas for downhole applications, OEM’s
for engine internals and many other industries use this process to enhance wear, scuff resistance and
fatigue life. Well, it turns out the process has another attribute ‐ corrosion resistance. A by‐product of
diffusing the iron and oxygen atoms with nitrogen and carbon at a low temperature results in surface
that has negligible dimensional distortion and is rust resistant. Comparisons via salt spray testing show
that stainless 316L marks at 420 hours, 1045 carbon steel‐ACE marks at 320 hours whereas untreated
1045 carbon steel marks within 90 minutes. A real advantage in the machinery mounting industry!

Press Release June 2010 RotaChock® ACE Anti‐Corrosion Enhanced RotaChock® Machinery Mounting Solutions is leading heavy industry into more trouble‐free installations. The RotaChock® ACE assists machinery mounting stakeholders with a rugged solution for rust problems. Driven by our innovation and solutions provider philosophy we are implementing a new material process to our RotaChock® products for owners, operators and fabricators of complex machine installations. The RotaChock® is a reusable machinery mounting chock for rigidly mounted machines. The RotaChock® eliminates soft foot and is a proven success. The RotaChock® has a large adjustment range which is coupled with a significant self leveling capacity for an easy to use chock that results in a high quality installation. The company’s charter as a solutions provider understands and responds to the needs of our customers to address costs, technical needs and life cycle issues. ACE is one of our latest innovations!!
While our stainless steel products address the technical and life cycle concerns, the cost of the core material is not appealing for all applications. For most of the land based applications, the chocking system is exposed to the weather which means plain ferrous based materials require maintenance. After thorough investigation and laboratory testing, Machinery Mounting SolutionsTM has selected a process that diffuses the ferrite regional layer of carbon steel and alloy steel with carbon and nitrogen.
The result is an enhanced rust resistance surface and improved wear attributes. Inherently, the RotaChock® is strong, stiff and the economical solution for the installation of machinery that requires coplanar mounting surfaces. Adding to our portfolio the RotaChock® ACE addresses the cost concerns of the marketplace for a long life cycle and low maintenance. Contact Machinery Mounting SolutionsTM for details.

Selection Methods for RotaChocks
Selecting a RotaChock can take three methods:
1) Bolt Size Method:
Select a RotaChock based upon the mounting bolt size. For example: 1”Bolt = RC4 (please refer
to the brochure).
Designers Notes:
a) The RotaChock diameter versus the foundation mounting surface. The bottom should be
fully supported
b) The gap (distance from foundation to the component mounting surface)
c) The material (carbon steel and carbon steel with our ACE process will be the best for most
applications) stainless steel is also a stocked solution and other materials are available.
2) Chock Calculation Method:
a) Provide weight, operating characteristics, foot print, gap and bolt size. A sizing calculation
will be provided. Also, see the Designers Notes above.
3) Comprehensive Chocking Plan Method:
a) Complete and submit the data sheets provided on the subsequent pages or download the
files from our website.
Designers Notes:
This Chocking Plan Method is typically recommended for Class applications.
Further, please note in your data sheets submittals any special environmental applications
i.e. High‐Shock, Arctic Circle, Nuclear etc…
This method recommends the chock, positioning of chocks, bolting design and bolt torques.
Machinery Mounting Solutions typically provides mounting kits. Please contact us for this
comprehensive supply option.

Detailed Installation Instructions
Chocking
Introduction
Chocking is the interface between machinery and the foundation structure. The function of this
interface is to create a coplanar surface for the installed machinery. The RotaChock® creates
the machinery mounting plane effectively and efficiently. The following instructions were
prepared for those that are new to mechanical chocks or those that need a refresher that
mechanical chocks are not shims – they are gap fillers. They are intended to create a coplanar
mounting surface for your machine quickly and easily. If you follow these instructions, the
installation should be completed in less than one hour. If it is taking longer, contact us!
Pre‐Requisites for Chocking
System design ‐ Considering any chocking system includes ensuring the foundation is
structurally stiff for the static and dynamics of the equipment plus the forces from the
environment. Each industry has a different consideration for environmental forces i.e. military
Grade A shock requirements are vastly different from petrochem pump systems and the
chocking system must meet or exceed the requirements of the application. Defining and
understanding these topics are the responsibility of the design activity but Machinery Mounting
Solutions can assist.
System design considerations specific to the RotaChock® include chocking thickness (gap) and
bottom part support.
Step 1) Using the mounting bolt size make a
preliminary selection of the RotaChock®. From the
RotaChock brochures select a configuration and
nominal design height (gap).
Step 2) Insure the foundation width will
accommodate the RotaChock® diameter. The RotaChock® bottom part should be fully
supported.

Sizing Calculation – Contact Machinery Mounting Solutions, to insure the best sizing of the
RotaChock®. This is free service. The rule of thumb solution is to select a RotaChock® based
upon bolt size but for many applications technically sound and better economic solutions will
be offered.
Jacking Devices – Moving the machinery into plumb and/or alignment is most efficiently
positioned by using jack bolts. There are other techniques such as our
bolt and nut, hydraulic jacks or wedges but no matter the jacking device
it needs to be clear of the RotaChock. The design of the package should
take in consideration ease of installation, access and the lifecycle of the
machinery. RotaChock® is a mounting chock and we recommend that it
not be used as a lifting device – it’s just too much work – keep it simple.
Machinery Checks
Clean the underside of component mounting foot. Check the mounting area for damage or
debris and take corrective action.
Foundation Checks
Clean the mounting surface and if primed that there is only a light coat (1 or 2 mils) of primer.
Rocker Check ‐ Position RotaChock in approximate final location, apply hand load to top of
RotaChock and try to rock the RotaChock® assembly side‐to‐side. If it rocks, investigate the
reason and correct. In most instances the surface preparation is only some localized sanding.
Ed.1.5.2 ‐ RotaChock Information Book
19
A more quantitative check procedure follows but typically the rocker check is adequate.
Feeler Gauge Check – Push down on the RotaChock® and examine the circumference of the
bottom part at the foundation with a feeler gauge of 0.05mm (0.002”). The acceptable
mounting surface check is achieved when the feeler does not pass completely through the
interface area

Alignment
Accomplish alignment per machine/system target requirements for cold alignment, thermal
growth and crankshaft deflections using jacking devices.
Because the RotaChock® is a mechanical device align the unit 0.002” (0.05mm) above target.
The 0.002” (0.05mm) is a nominal dimension to accommodate extrusion of the lubricant in the
chock’s internal surfaces. There may be some slight variances due to machine load, chock size,
foundation surface condition and bolt stretch and we recommend that installers take notes of
their equipment alignments to make the next alignment event quicker.

Chock Preparation
Unpack the RotaChock
Carbon steel RotaChocks® are packaged with LPS3 on the surfaces‐ Clean off the top of the top
part and bottom of the bottom ring with a degreaser solution.
Notes:
The RotaChock® has slots for adjustment. Many tools can be used to tighten the chock. Tools
that can be used for the RotaChock include: Flat head screw drivers (with tip slightly ground off
to provide grip in the slot), chisels or dowel pins. We also have spanners for sale but they are
not essential for a perfect installation.
The RotaChock® is designed with a buttress thread. The force required to tighten the chock in
place against the gap is minimal (20 – 30 lbs‐ft). Because of this thread configuration they will
lock sooner (less force) than other mechanical chocks that do not use a buttress thread
configuration.
Slot sizes:
Chock Installation
Place the RotaChock® in position (generally concentric with the bolt
hole). Fit the RotaChock by rotating (unscrewing) by hand. A single
person using 2 tools should tighten each RotaChock®. Please do not
have multiple technicians tightening the chocks. Once each
RotaChock® is fitted, take the load off of the vertical jacking screws
and install foundation bolts.
Ed.1.5.2 ‐ RotaChock Information Book
21
After tightening foundation bolts to the required torque, check the final alignment. The
alignment should be within cold alignment target tolerances and with no softfoot.
SHOP HELPER:
NOTE: The RotaChock is simply a gap filler device for the space between the skid/foundation and the piece of equipment. Zero softfoot installations are typically achieved within 15 ‐30 minutes depending on the number of mounting positions. If you do not achieve zero softfoot installations within 1 hour contact us, there is something amiss with the mounting procedure or the skid/foundation. Again, these are gap fillers not shims! Position the machine where you want it on jacking screws or similar devices. Below are some jacking device ideas for applications where the equipment provider placed their jacking bolts too close to the mounting hole – it is not a problem just something to be aware of before chock installation.
Ed.1.5.2 ‐ RotaChock Information Book
22
An alternative jacking setup is to use a nut and bolt which is slightly shorter than the height of the
system intended gap. A 1” bolt and nut(s) is enough but use whatever you are comfortable with.
Remember the machine will only be on these for 15‐30 minutes. 3 per side should do it for long
machines. Position the component for its final vertical location/alignment, on the jacking devices.
The horizontal moves can be accomplished on the jacking devices or the RotaChocks.
Install the RotaChocks – adjust to fit by hand. Then, one person using RotaChock tools, flat head screw drivers, allen wrenches or anything else (flat bar) that fits the slots tighten the RotaChocks. Remember the RotaChocks have buttress threads so it does not take much force to make these chocks tighten (friction lock with about 20 ‐30 ft‐lbs) in the gap between the component and its foundation. Loosen the jacking bolts. The RotaChocks are now taking the weight of the machine. Install and tighten foundation hardware. Please note: Directly out to the packaging RotaChocks have lubricant in the thread and spherical surface. As the bolts are tightened, this lubricant will be extruded out. We recommend that you allow approximately 0.002” above your position target for this extruded lubricant. Just a note: this is not crush‐ if the chock crushed it would never rotate again. These chocks only crush when we tell them to! And it usually will require very large servo‐hydraulic presses or high explosives. Also, there is a long (wrong) approach to machinery mounting with RotaChocks. We call it the Lottery Approach! Make skid/foundation plumb on shop floor (cool), measure RotaChocks to some height to achieve the center line target of your machine and install the chocks . Install the machine and tighten mounting bolts. If you have no softfoot with this procedure YOU ARE LUCKY! Most of the time, you will not be that lucky.
Ed.1.5.2 ‐ RotaChock Information Book
23
Here’s what’s happening! The machine is really still sitting on three points – yes, in the case of really big
machine it maybe four or five – but it still has softfoot! The machine’s feet are not coplanar and the skid
is twisted! So you and your helpers get out hydraulic jacks and start lifting the machine at a point and
ask ”… how much does a RotaChock adjust per adjusting hole?” Forget it! You will chase softfoot
around the machine for hours – like a shim. Sure eventually you will get it. We recommend that you
save your energy for the next rodeo and follow the instructions provided earlier in this section. For
years before mechanical chocks and epoxy resins – we did it! That’s why we developed the RotaChock!
Don’t chase soft foot around! Do not wait for epoxy resins to setup. Do not make machinery mounting
difficult – use RotaChocks!
AGAIN, set the machine on target using jacking screws. Fill the gap with the RotaChock. Release the
jacking screws. Tighten the mounting hardware. You are finished! Sure for your QA documents confirm
alignment and zero softfoot, get the sign‐off and pick‐up your tools!
Just to drive it in: The RotaChock is not a shim! It is a gap filler – a chock! The alignment process for the
RotaChock is the same as for poured chocks. Align as required for the thermal conditions and fill the
gap. Be done in minutes – use the RotaChock!
Guess what? In the field it is the same way – because that foundation will rack in transportation. During
commissioning, alignment and softfoot are checked and 85% of the time the chock will need to be
adjusted. The RotaChocks will be there and ready to be adjusted to accommodate the new machinery
plane.
Protecting the RotaChock®
The RotaChock® uses a relatively fine thread interface, debris in the thread will make
the device hard to adjust. Protect the thread from debris while the unit is being
stored, transported or in the field. Also, the carbon steel chock will rust and must be
preserved. All methods for steel preservation are acceptable but please note the
thread should be protected during the lifecycle.
What Lubricant is used on the RotaChocks?
All RotaChocks have the threads and spherical top part lubricated with Loctite® Nickel Anti‐
Seize. Carbon Steel RotaChocks have, the outer surfaces are coated with LPS 3® Premier
Rust Inhibitor. The LPS‐3 should be cleaned off of the top and base surface of the chock.

Foundation Bolts
Each industry has specifications for foundation bolting and each manufacturer and customer
has their own bolting preferences, follow their requirements. It does matter for the RotaChock.
We use the size, grade and style of bolting information supplied by the customer for our bolt
torque calculations. For the chocking plan method, we recommend bolting arrangement best
for the application. We have time proven solutions which have been used across multiple
industry sectors.
Bolt Torque
The founders of Machinery Mounting Solutions have over 100 years experience in machinery
mounting and foundation bolts. The final torque and resulting stretch of the bolt is critical to
the life cycle performance of the machine. The bolt stretch has to take into account the bolts /
nuts, washers, foundation interfaces, chock height, we have taken these into account in the
minimum stretch required to maintain frictional forces in the nut.
Contact Machinery Mounting Solutions for detailed design solutions.
We offer design, and supply foundation studs and fitted studs to suit your application.

Spherical Spacers
The purpose of chocking is to create a perfect coplanar mounting surface for the machine(s).
The RotaChock product is a mechanical chock that corrects for the inherent mounting surface
inconsistencies between a machine and its’ foundation – coplanar mounting surfaces are
assured! Now that the unit is mounted properly using RotaChock, pour chocking systems or blocks and
shims what about the mounting hardware? Illustration 1 depicts two configurations currently in the

Hardware Bending
No matter what type of chock is installed, the bolt is stressed into position during installation. Usually in
production line settings it is not a problem, but all the time, over time, the hardware will loosen. The
loosening hardware will affect the vibration, maintenance requirements and eventually the chock
and/or equipment. All service teams have a story of at least a few packages out there that are having
problems relative to mounting hardware loosening. It is not the equipment, not the chock and not the
service guy not taking care when tightening the hardware. It is a bolt or stud that is stress relieving due
to angular misalignment.

Spherical Spacer Solution
The Machinery Mounting Solutions Spherical Spacer accomplishes two functions: 1) it creates hardware
planes and 2) bolt elongation. The RotaChock® by design is capable of taking the clamping force created
by the hardware at any length. Whereas the rule of thumb for poured epoxy resins is about 12 bolt
diameters minimum. We offer the spacer to suit your application while creating a fastener that is in
pure tension and no longer a maintenance problem for the life cycle of the machine. Illustration 3 and
Table 1 depicts our part number and diameters offered. The angular offset maximum angle is 4 degrees.
The length of the spherical spacers can be manufactured to your requirements.

Adjusting the RotaChock® is a simple task that can be accomplished using a large variety of tools. From years in the field, we have learned that having options is a significant RotaChock® advantage. The slots are shown in Illustration 1 below. Tools like: Flat head screw drivers ( with tip slightly ground off to provide grip in the slot ) , chisels, Allen wrenches, dowel pins or similar hand tools accomplish the job. Further, we recognize some technicians like the feel of a spanner. In support of customer inquiries we stock a range of adjusting tools:

RotaChock Foundation – Design Notes
Q. How much coverage does the RotaChock need?
A. Insure the foundation width will accommodate the RotaChock® base part diameter. The
RotaChock® bottom part should be fully supported. Not having the base ring fully supported
can distort the thread in the base. The distorted thread could lock the device prematurely.
Prevent a problem and support the base.
Coverage of the top part is usually governed by the bolt position of the machine. As long as that
position is acceptable for equipment manufacture for shear forces (side pullout requirements) from the
machine it will be acceptable for the RotaChock.
SATISFACTORY UNSATISFACTORY
GAP
Ed.1.5.2 ‐ RotaChock Information Book
29
Q. Can a spacer be added to mounting system?
A. Yes, but we caution the installing activity to control the configuration of the spacers and
condition of foundation surface. Below are some scenarios that we have seen in the past years.
Double chock on a single shim:
The scenario is:
The foundation is off slightly (normal condition)
The shim (usually thin) is sheared and not necessarily flat.
A unit is aligned properly on the jack screws. Chock 1 is installed (at the four corners) the bolts are
tightened. Technician A walks away and is happy with a good job.
The Technician B comes in and installs chock #2 and tightens everything up. Next thing to check is
softfoot. You got it! Softfoot!
What’s happened?
The shim is not flat but it is thin enough to deform (spring) into contour as clamping force to chock #1 is
applied. The remaining shim under chock #2 is now a loaded spring (un‐calibrated). The RotaChock with
its buttress thread tightens with a small amount force – as designed! It must be the chocks fault!
We offer taller top parts to accommodate the shop and field. If spacers are required, we recommend
milled flat spacers which are positioned between the component foot and the chock.
Ed.1.5.2 ‐ RotaChock Information Book
30
Q. What other considerations need to be taken into account?
A. Some installations require cutouts to be made in the I‐Beam webs to gain access to the
foundation bolts. Below are some illustrations.
Incorrect – fastener access is too large for the diameter of the chock and the removing the web material
is too close to the mounting flange. The results are a greatly reduced beam strength and system that
acts like it has softfoot.
Improved fastener access maintains the strength of the mounting flange. Add a spacer to access the nut
for ease of maintenance for the lifecycle.
