1. Introduction
The MagnaMount® weigh module provides an accurate method of weighing heavycapacity tank, truck, and railroad track weighing applications. The mount is
available in three heavy-duty capacities: 50,000 lb, 100,000 lb, and 200,000 lb. The
load bearing plate is constructed of high-grade carbon steel, which gives the mount
its high-strength capabilities. The unique Teflon®-coated load bearing plate permits
multi-directional movement to offer accurate weighing and compensate for temperature variations. The mount shields the load cell on four sides to protect it from
shock and side loads.
RTICSP1, RTICP1, and RLCSP1 compression canister loads cells are compatible
for use in the MagnaMount. All are constructed of stainless steel, hermetically
sealed, and rated for 150% maximum overload.
The installation should be planned by a qualified structural engineer. Each installation is unique, and this manual is meant to serve only as a general guideline for
installation.

2. Parts Assembly
The MagnaMount can be assembled as one unit and hoisted into place on the
foundation, or it can be assembled part by part onto the foundation. This section
describes the assembly of the mount into one unit.
2.1 Assembling the Base Plate
1. Screw the four leveling bolts into the base plate.
2. Place the two corner stands on the base plate (see graphic below).
3. Place the flexure plate over the two corner stands.
4. Place the two anchor blocks on top of the flexure plate in line with each
corner stand.
5. Screw anchor bolt through the anchor blocks, flexure plate, and corner
stands to the base plate using the eight anchor block bolts and washers
(only six anchor block bolts and washers for the 100,000 lb capacity mount
and only four for the 50,000 lb).
6. Torque the anchor block bolts to spec (see torque value table, page 4).

2.2 Assembling the Retaining Plate
1. Install tension pins 1/4" x 3/4" in retaining plates and bottom plates. Leave
1/4" out of plates.
2. Place the bottom plate on top of the flexure plate (see graphic below).
3. Position the top mounting plate under the flexure plate aligned with the
bottom plate.
4. Screw the top mounting plate to the bottom plate using the top mounting
plate bolts, lockwashers, and washers.
5. Torque the top mounting plate bolts to spec ( see torque value table, page 4).
Note:
The top mounting plate is on the bottom of this assembly and on top of
the load cell.
6. Place the bottom fabreeka pad on the bottom plate.
7. Place the top fabreeka pad on the bottom Fabreeka® pad.
8. Place the retaining plate on top of the top Fabreeka pad.

2.3 Assembling the Dummy Load Cell
1. Place nine shims on the load cell mounting plate (only four shims for the
100,000 lb capacity mount and only six for the 50,000 lb).
2. Place the dummy load cell on the shims (see load cell assembly graphic).
3. Screw the load cell screw into the dummy load cell from the bottom of the
load cell mounting plate.
4. Insert the dummy load cell assembly in the mount between the base plate
and the top mounting plate. Add or subtract shims so top of dummy cell just
touches the top mounting plate with no load.
5. Screw the load cell mounting plate bolts with lockwashers into the base
plate.
6. Torque the load cell mounting plate bolts to spec. See the following table
for all necessary torque values.

Note:
After the mount is fully installed on the foundation and the scale deck I-beam is
secured to the mount, the dummy load cell can be replaced by the actual load cell.
Refer to Section 3.3.4, Installing the Load Cell and Section 3.3.5 Removing the
Load Cell.
