  • Page 6: Choosing A Site

    Choosing a Site The first step in installing the scale is to choose an appropriate site. Pertinent steps in choosing the site are: - Ensure that the site has adequate approaching / exiting distance to comply with state and local Weights and Measures regulations. Scale length and scale elevation (maximum fall per foot allowance) will impact the total area requirement.
  • Page 7 - Check all state and local Weights and Measures requirements before breaking ground to ensure compliance with all regulations. - Obtain all necessary permits for construction. - Check all public utilities to ensure that your site is free of underground lines, pipes or hoses.

  • Page 8: Site Preparation / Foundation

    - The base plates, which support the load cells, are designed to be anchored to the foundation (or pier) by using expansion bolts placed in concrete after curing. - B-TEK Scales recommends the use of 3/4” X 7” length expansion bolts, which provide greater flexibility, to ensure proper positioning of the scale.

  • Page 9: Unpacking

    Unpacking Unload the shipping crate of scale components prior to unloading scale platform modules from the truck to verify you have everything included on the packing list. Open all boxes for individual equipment pieces and perform a physical inspection to be certain all components are present and have not been damaged during shipping.

  • Page 14 It is recommended to layout all foundation base plates prior to permanently anchoring to the foundation. Set the foundation plates in place. Do not secure the plates to the foundation at this time. Ensure that the foundation base plates are all level with each other. Shim plates for use on the top of the foundation base plates are included.

  • Page 15: Locating Plate

    Locating Plate Secure the load cell locating plates to the foundation base plates using the included hex head bolts (2) M12 X 40mm and (1) M8 X 40mm, lock nuts and flat washers. Starting with the first 4-cell module locating plates, place a dummy load cell assembly into the base ring of each locating plate.

  • Page 16: Module Assembly

    Module Assembly (if required) The individual weighbridge modules may have been specified to be shipped to the installation site already assembled. If not, they must be bolted together prior to being placed into / onto the foundation. In addition, if not pre-assembled at the factory the conduit will have to be placed in the module prior to installation.
  • Page 17 Module Assembly (continued) The left and right halves of weighbridge modules will be bolted together through their respective connection plates. Be sure that the modules being bolted together are matching pairs and have the same type of load cell support ends. First insert (2) 1/2”-13 X 2-1/2”...

  • Page 19: Conduit Installation

    Conduit Installation If not ordered as pre-assembled at the factory, the conduit for cable runs must be installed in the weighbridge. The lengths of conduit will be bundled together with your “scale package” and can be inserted thru the lifting lugs located on the inside of either of the module halves.

  • Page 20: Center Deck Panel And Clip Installation

    Center Deck Panel and Clip Installation Steel deck Centurions, 11’ and wide utilizes center deck panels between the left and right connected halves. These cover plates are secured by use of a deck panel clip (#100-60084) and cap screw (#HW-B-1/2-13X1.5SHCS) which are tightened against a panel tube inside the scale module.

  • Page 21: Lifting Modules Into Place

    Lifting Modules into Place Note: If the scale is a concrete deck version, refer to the following sections for shoring and crowning instructions prior to lifting the modules into place. The first module to be placed onto the foundation is a 4-cell module which should be placed directly after the end wall.
  • Page 22 Prior to installing the weighbridge module onto the dummy load cell stands ensure that safety supports such as wood blocking is placed under the weighbridge module being lifted. Lift the 4-cell module over the four dummy cell stand assemblies and slowly lower the module so that the button on top of each dummy stand is inserted into the thru hole located in the module’s load cell nest.
  • Page 23 CORRECT WRONG LOAD CELL / DUMMY STAND ALIGNMENT Take a measurement from the outside edge to the end wall on both sides of the module end plate to ensure that the module is parallel with the end wall. The measurements should be within 1/8” of each other. If they are not, lift and adjust the module to achieve squareness.

  • Page 24: Connecting Modules

    Connecting Modules With the first 4-cell module in place you can now lift the next adjoining module into place and attach using the load cell nest brackets. This will be a 2-cell module which consists of upper connection brackets on one end, and load cell connector brackets on the other.
  • Page 25 Lower the module into place so that the connection shelves rest on top of the 4-cell module’s load cell nests. Lower the opposite end of the module so that the button on top of each stand is inserted into the thru hole located in the module’s load cell nest. LOAD CELL NEST UPPER CONNECTION SHELF...
  • Page 26 Adjust the 7/8” X 3” bolts that run lengthwise with the scale so that the distance between the end module plates is 9-3/4”. This measurement should be taken on both side of the modules to ensure that the cover plates will fit between the modules properly. As a reference, you need approximately 10-3/4”...
  • Page 27 Each subsequent 2-cell module, if used, will be installed identical to the module in the previous section, with the load cell nest upper connection bracket mating with the load cell nest lower connection bracket of the adjacent module, with the opposite end of the module resting on dummy load cell stands.

  • Page 29: Concrete Deck Scales Preparation

    Approximately 24,000 lbs. of concrete will be poured into a typical 24’ x 11’ B -TEK Centurion weighbridge module. If you have questions about the shoring procedure, please call B-TEK scales at 800-266-8900.  The standard B-TEK Centurion concrete deck scale has approximately 6” of clearance from the bottom of the main structural beams to the top of the foundation floor.
  • Page 30  Shims (metal or wood) will be required to achieve proper elevation of the wood timber. Additional shims can be used in the center of the module to create a positive crown. Refer to the following section in the manual regarding crowning the scale module.
  • Page 31 Crowning Instructions Once the modules are in place and supported on dummy load cell stands or load cell stands, you must verify that there is a positive crown in the modules. This is to ensure proper rain and snow runoff. The same shoring timbers used for the bottom pan support can be used for crowning the module.

  • Page 32: Adjusting The Checking

    Adjusting the Checking Once assembled, verify that the scale is centered in the foundation. If it is not, make the appropriate adjustments. With the modules bolted together, adjust the end bumper checking and the side checking stands. The poly bumpers on the end wall, and the bolt heads on the side checking stands should be approximately 1/16”-1/8”...

  • Page 33: Replacing The Dummy Load Cell Stands

    Replacing the Dummy Load Cell Stands Once the end and side checking has been adjusted the dummy load cell stands will need to be removed and replaced with the actual load cells. It is imperative that the checking has been adjusted to minimize the lateral movement of the weighbridges when replacing the stands.
  • Page 34 Once the dummy load cell stand has been removed, replace with the load cell Assembly per the diagram below: Start by placing the ceramic isolation disc into the circular ring which is part of the locating plate. The load cell bottom cup is then placed inside the isolation disc, with the anti-rotation pin insert into the cup’s blind hole.

  • Page 35: Aligning The Load Cells

    Checking the Alignment of Load Cells Once the load cell assembly has been installed it must be checked for correct alignment. Using the B-TEK load cell surface level, supplied to authorized dealers, attach to the lower diameter of the load cell using the integral magnet. The magnet can be adjusted in and out by turning the set screw.
  • Page 36 Once the entire scale has had the load cell assemblies installed and aligned correctly, readjust all bumper checking assemblies to within 1/16” - 1/8”. At this time drill and install all of the anchors for the base plates. Anchors are sug- gested to be 3/4”...
