  • Page 4: Introduction

    Introduction This manual is meant as an installation guide for the B-TEK Railroad Approved series of full electronic railroad track scales. Scales are available in both AAR and AREMA designs. This includes the following models: BT-RA-CPD The RA and RS series of railroad track scales is available in standard module lengths of 12'-6" for a "single" and 25' for a "double".

  • Page 5: Before Installation

    Before Installation Prior to installation verify the following: • The scale design will meet the customer's application correctly • The scale is located so that it is aligned with existing rail track and has a minimum of 75 feet of tangent track at each approach.

  • 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, as well as the governing rail line requirements.
  • Page 7 Excerpts from the Association of American Railroads Scale Handbook include the following: Location: Scale should be so located that an adequate foundation and at least 75 feet of tangent track at each approach to the weigh rails can be provided. Elevation: In areas with poor drainage, the scale shall be raised to such an elevation that drainage of the surface water shall be away from it.
  • Page 8 Where a special scale house is required, a suitable and substantial building shall be provided. To ensure prop- er operation of the indicator and/or recorder, the house shall be equipped with proper environmental control. Scale House Location: The lateral clearance between the scale house and centerline of scale or any track shall not be less than 8 feet, unless otherwise required by law, or the servicing railroad.

  • Page 9: Site Preparation / Foundation

    Site Preparation / Foundation Check and review all blueprints prior to starting work. Steps to follow include: • Use only the latest engineering drawing sent with the scale order. • Using a transit, locate the stakes where the scale foundation will be constructed. •...

  • Page 10: Rail Scale Installation

    Rail Scale Installation Prior to installation of the scale it is important to have the proper tools and equipment. The following is a sug- gested list : • A mobile crane with a minimum capacity of 11,000 LBS. • Foundation drawings •...
  • Page 11 Measuring from established centerline use the provided foun- dation drawings to snap center lines at all load cell/checking stand foundation base plates. Place supplied jam nuts and washers onto foundation bolts then set supplied load cell/checking stand foundation plates to required height per supplied B-TEK foundation drawings. Ensure plates are leveled. Install washers and nuts onto leveled plates.
  • Page 12 For each load cell in the scale, a load cell mount kit will be provided. It consists of the following: • Lower receiver • Debris foam ring • Upper Receiver • (1) “Y” grounding strap • Thick ring plate • (1) bag containing anti-rotation pin •...
  • Page 13 Place weigh bridges onto dummy pins. Verify that all four dummy stands are inserted concentrically in the mounting plate through holes with no binding and that the bridge rests flat on top of the dummy cell pins. 2020 www.B-TEK.com Rail Scale Installation Manual...

  • Page 14: Connecting Modules

    Connecting Modules (If Double Bridge) With the first end module in place you can now lift the next adjoining module into place and attach using the supplied mounting plates and splice plates. The module will be lowered onto the mounting plate connected to the end module that was installed first, and onto the dummy stands at the opposite end.

  • Page 15: Confirm Required Positioning

    Confirm Required Positioning Verify weight bridge is centered on established centerline of track (for side to side checking). Verify weigh- bridge is centered and gaps are equal at each end wall (for end to end checking). If adjustments are required, loosen the two ring plate bolts and adjust ring plate to achieve the required adjustments to center the weigh- bridges.
  • Page 16 Use B-TEK leveling tool to plum all load cells. Loosen bolts in ring plate to adjust load cell to plum. Tighten ring plate bolts completely after load cells are plum. Locate checking rods, nuts and washers. Install nuts and washers as detailed in the image below. Place assemblies into checking rod stands as shown.

  • Page 17: Grouting

    Fasten rods into place with remaining nuts and washers. Tighten nuts enough to prevent end to end movement of the rod, but not so tight that the washers cannot rotate freely. Grouting Build grout boxes around load cell/checking stand foundation plates. Grout Specifications: •...

  • Page 18: Rails, Rail Clips And Anti-Creep Devices

    Rails, Rail Clips and Anti-Creep Devices The scale is designed to accept no less than 115 lb rail with Foster #62 rail clip. The approach rails and scale weigh rail are required to be the same weight and dimension. The approach anchor bolts, approach rail plates, rail clips, and anti-creep devices are all optional items.
  • Page 19 Positive means must be provided to prevent the creeping of the approach rails and to maintain a clearance which shall be not less than 1/8 inches or more than 5/8 inches between the approach rails and the weighrails. The AAR Specifications state that the rail on the approach and the weighbridge shall be anchored to pre- vent creeping of the rails.

  • Page 20: Connecting The Grounding Cables

    Connect the Grounding Cables (Rail) Connect the grounding cables from each load cell to the threaded cable stand-off on the weighbridge. Additionally, connect a grounding cable from the M8 bolt/nut on the locating plate to the same stand-off on the weighbridge.
