Weighbridge with Self-Contained Modules in Place Assembly Time Estimates When scheduling installation for a typical three-module, 70' truck scale, plan for a two-hour minimum crane rental to place the modules into position.
Figure 1-2. Unloading Modules From Truck Serial Tag The serial tag on an ATV Series portable truck scale truck scale is found at the end of the scale near the SURVIVOR logo (see Figure 1-3). A duplicate tag is placed inside of the J-box pocket (see Figure 1-4). Figure 1-3.
Assembly The following sections detail deck module assembly, setting load cell mounts, and scale relocation. Deck Module Assembly NOTE: The bridge module is placed on truck last. Set it off to the side when unloading modules at installation site. 1. Considering the location of the indicator, place first self-contained module of the ATV into position on a flat surface.
Setup 1. Back off shipping bolts located on ends of weighbridges (four for each self-contained module) until each bolt is no longer inserted in the scale (see Figure 2-5). Shipping Bolt Figure 2-5. Weighbridge Shipping Bolts 2. Remove the bolt which connects the stand to bulkhead base (see Figure 2-6). Re-install this bolt in the bulkhead base after the stand is raised in Step 4.
Scale Relocation Use the following steps when relocating the ATV portable truck scale series truck scale. 1. Remove load cell cover plates. Load Chain Cell Wiring Figure 2-9. Load Cell Cover Plate Removed 2. Remove hitch pin that holds stand in retracted position (see Figure 2-9). 3.
Connecting Electronic Equipment Electrical Ground Connections Sixty feet of six-wire homerun cable is supplied for wiring the J-box to the indicator. It is best to run this Improper grounding systems on outdoor in 3/4" galvanized metal or plastic conduit from the Caution truck scales often cause corrupted data J-box to the indicator.
Be certain each load cell grounding strap is securely A separate grounding system conductor must extend connected to the top plate and bottom plate of each uninterrupted from the main service panel ground to load cell mount.

Trimming and Calibration The following section describes steps in trimming individual cells and pairs of cells, and calibration of the ATV truck scale. See J-box instructions located in the J-box for details on trimming. Overview and Equipment Required Load Cell Trimming Individual load cell signal trimming (equalizing the signal output from each load cell) must be done first along each side of the scale so all cells on a side have equal signal output.
3. The lowest reading of the four is the reference cell. Do not change that cell’s signal. Instead use the individual cell potentiometers for the other three cells to reduce those signals to match your reference cell. Remember that you turned all pots to full signal before starting, so you can not increase the signal from any cell —...

Equipment Required Truck scales are routinely calibrated using 25% of the capacity weight of the scale. Certified Class F test weights equaling at least 12.5% of the scale’s capacity are required for calibrating a commercial legal-for-trade truck scale. In addition, some type of weight for a substitution test of an additional 12.5% of the capacity is required. This can be the test-weight truck, bags of sand, or any convenient items easy to load onto the scale.
Load Cell Replacement Replacement Procedure 1. Position jack beneath one of the weighbridge’s main frame members close to the load cell mount. (Allow room for load cell removal and installation.) Raise jack approximately 1/2" and put setting block(s) under the scale deck. Caution As a safety precaution, always use setting blocks when jacking scale module.
