Installation Overview Prior to installation of the scale it is important to have the proper location and application for the particular scale being installed. The typical procedure for the installation of scales covered in this manual will consist of the following: •...
Optional Pit Frame Installation Instructions Cut out concrete 1’ larger than pit frame side (6” on each side) and dig out minimum of 8” deep. Note, you might need to cut larger area if the surrounding concrete is not level to make angled approach to the scale a gradual slope. Install 1”...
Unpacking Caution: The scale platform is heavy and can be awkward to handle. Exercise extreme care when lifting the scale platform to avoid personal bodily harm or damage to the equipment. Remove the packing material and inspect the scale for any visible damage occurring during shipment.
Assembling the Scale Prior to installation of the scale the leveling feet must be threaded into the tapped through holes in each of the four load cells bolted to the corner assembly in the scale. In the case of a Workhorse heavy duty platform scale, four corner load cell assemblies with upper and possibly lower plates will need to be assembled and attached to the scale.
Assembling the Scale - Workhorse Workhorse heavy duty platform scales need to have the leveling foot threaded into the load cell, then the top mounting plate will need to be attached to the scale weighbridge by four mounting bolts. The leveling foot may sit on the floor, may include foot locating plates, or may rest on topside of a bottom mounting plate, all depending on the application.
Assembling the Scale - Rocker Pin Suspension Place base frame onto the floor making sure the frame is level. Install pins into all four corners. The rocker frame design does not allow for height adjustments. Temporarily place the scale onto the load pins to verify the scale does not rock from corner to corner.
Anchoring Rocker Pin Suspension Frame There are two anchor locations per corner. If shims are required, for additional height, place supplied shims under each corner. Drill 5/8” diameter hole, 2” into the cement. Do not ream or allow the drill to wobble. Repeat this step for all of the anchor locations.
Opening and Cleaning - Lift Deck To open scale: Locate hand hole(s) and latch(es). Pull ring towards you to release locking bolt. Once all locking bolts are released lift deck. Once deck is open, locate built in locking/support bars. Locate built in upper clevis pin(s). Remove cotter pin and place support bar onto upper clevis pin.
Summing Board Connections With the exception of the Workhorse, floor and drum scales are typically shipped with the load cells bolted in place and pre-wired to the summing board. Load cell wiring will be as follows for Sensortronic cells: Note: For alternate interchangeable load cell brands check calibration certificate for wiring specifics or refer to the drawing below.

Connecting the Indicator Depending on the type of scale package and/or indicator purchased, the connecting or “homerun” cable between the scale and indicator may or may not be provided. A 4-wire cable is required to connect the two together, or an optional 6-wire cable for longer runs over 50 ft.
With all of the potentiometers at “maximum signal” set the test weight over one corner of the scale platform and record the weight shown on the indicator. Repeat this process for the remaining three corners. Whichever corner load cell has the lowest reading will be used as the reference and will not be adjusted.
Load Cell Replacement If a load cell should need replaced, verify the part number with the spare parts list in this manual. Replacement cells should be of the same capacity of the cell that is being replaced, as well as of the other cells in the scale. Lift the scale platform using lifting eyes, fork lift, or hydraulic jack.
