Rice Lake SURVIVOR PT Series - Manual (Page 8)

4 Survivor PT - Pit Type Truck Scale
2.0 Assemble Deck Modules
The modules are designated either as an end module or a center module. All two-module scales will have two end
modules, while longer scales will have two end modules and one or more center module (Figure 2-1).
Figure 2-1. Center and End Modules
In a three module scale, the end module is the first to be positioned on setting blocks followed by the center
module. The last module to be assembled is an end module. Scales with more than three modules will have
additional center modules installed.
Example – a 100' scale would have two end modules and three center modules.
2.1 Place End Module A
Place one 15 1/4" temporary setting block on the top of each pier and position them so that they will not interfere
with the installation of the load cell mounts. The scale module should be 3/4" away from the bulkhead ramp and
3/4" from each pit wall side. By using the 15 1/4" blocks, the top of the main beam will be approximately 6-1/3"
below the top of the pit.
2.2 Place and Attach Center Module
To assist in easy assembly of the center module, make sure that both modules have direct end-to-end surface
contact.
10. Place four 15 1/4" setting blocks on top of the piers in the center sections.
11. Position and place the center module on the setting blocks, making sure that both the end module and
center module end plates are aligned.
12. Check that the module is centered side-to-side in the pit.
At the installer’s discretion, install the center section with the J-box on the near side to the scale house.
13. When both modules are aligned, insert the top three 1 1/8" bolts with flat washers, lock washers and nuts
on the outside of the beam. (Leave out the bottom bolt to facilitate load cell mount installation).
Tighten bolts and nuts finger tight until all modules are in place.
A long pry bar can be used to make small adjustments in module alignment, but it is easier to leave the
second module attached to the crane for making small alignment changes.
14. Install the three top bolts, washers and nuts on the inside of the beam. Install the bolts, washers and nuts on
the opposite beam using six bolts, washers and nuts. Tighten only finger tight.

Do not install the bottom bolt at this time.
