LIFT TRUCK SCALE
INSTALLATION
1. Unpacking
The LTS Lift Truck Scale is shipped on a pallet. A standard system will include the following components:
1.
2.
3.
4.
5.
6.
One (1) scale carriage assembly with safety plates
One (1) load cell cable assembly with mounting bracket
One (1) power cable
One (1) electronic indicator with mounting hardware
One (1) Operator / Installation manual
One (1) Side Shift Bracket (Optional)
Upon receipt of shipment, inspect to make sure the above listed parts are present.
2. Scale Base Installation
2.2.
Remove safety plate(s) from bottom of scale carriage assembly. Place the scale in a vertical position
on the edge of the shipping pallet, with the rear side outward. Examine the back plate of the scale
base at this time to locate the carriage alignment bolts. (Ref. figure: 1) The head of a bolt that
protrudes from the rear of the scale is known as the fixed carriage alignment bolt. There are also
several adjustable carriage alignment bolts protruding from the rear of the scale. These adjustable
bolts have a red lock nut located between the two plates. These bolts will be adjusted in step #4.
Note: If the lift truck has a take-up-reel device ensure that the Load Cell Cable Mounting Bracket is
located on the opposite side of the lift truck. Relocate the longer mounting bolt to the correct side
of the base prior to installing the base.
2.3.
Remove forks from the lift truck, and position the truck behind the scale assembly.
Warning:
2.4.
Raise or lower the lift truck carriage and tilt the mast forward to a position that aligns the anti-shift pin
on the scale assembly with the center notch on the lift truck carriage. Tilt the mast back to catch the
scale assembly and carefully raise the carriage to a comfortable working position. Reattach the safety
plates to the bottom of the scale assembly, so that the lip of the safety plate is behind the original
carriage (Refer to Figure #3).
Torque the Safety Plate Retaining Bolts to 125 Ft-Lbs.
Warning:
Note:
To avoid bodily harm care must be exercised while handling the scale base prior to applying
the safety plates.
Failure to properly torque the Safety Plate Retaining Bolts may result in Bodily Harm or
Damage to the Equipment.
The Center Cleat with Anti-Shift Pin should be centered with the middle notch of the truck
carriage. Verify that the Anti-Shift Pin is adjusted so that the Pin is located well within the center
notch area of the carriage. DO NOT OVERADJUST. The anti-shift pin should not touch the
bottom of the notch on the original carriage; this will cause side to side tilting of the scale. To
 LTS Scale Company, LLC

Rev B 1/26/16
properly adjust the Anti-Shift Pin, tighten the Pin down until it bottoms out then back the Pin off
1/8 of a turn.
2.5.
To assure firm and level mounting, the fixed carriage alignment bolt of the scale assembly should be
resting on the lift truck carriage. To attain a secure mounting, loosen the lock nuts (painted red for
easy identification), then back the alignment bolts off until the center pad is resting against the lift truck
carriage. Next, adjust the carriage alignment bolts so that they are just touching the lift truck carriage,
and then tighten the lock nuts (Ref. Figure #1).
2.6.
Remove the two (2) fork stop bolts, located in the upper corners of the front plate. Now reattach the lift
truck forks to the scale assembly, and re-insert the fork stop bolts.
2.7.
Position the load cell cable assembly to either the right or left side of the scale assembly. Select the
side opposite any hose or reel-type take-up device. Secure the load cell cable assembly to the longest
mounting bolt. This bolt can be moved to either side of the scale (Note: A special load cell-mounting
bracket is mounted at the factory for NTEP applications).

9 bracket, cable guard mount
10 1/2-13 bolt hex head
3.2. Inspect the rear carriage for pre-drilled and tapped holes on rear carriage.
3.2.1. If there is a hole on the end of the carriage then use #5 (bracket, side shift angle). One of the #7
bolts provided should fit (1/2”, 5/8”, or 14mm).
Run bolts all the way in until they hit
the back plate and the bracket is
vertically straight, then tighten the
jam nuts.
Caution: if bracket #5 is mounted
too high, side sifter will bend
bracket as it goes past end of rear
carriage.
3.2.2.
If there is a hole on the back of the carriage then discard #5 (bracket, side shift angle) and
attach bracket #1 (bracket, side shift) directly to the rear carriage using one of the #7 bolts
provided (1/2”, 5/8”, or 14mm).
3.3.
Use the cable ties provided to secure the load cell cable to the front and rear bracket. Operate
side shifter all the way to the left and right and make sure there is enough cable slack left
between brackets.
Caution:
Operate side shifter slowly in both directions and up and down. Check clearance from
moving parts. Make sure to leave enough slack in the load cell cable between brackets.

4. Indicator Installation
4.1. Location of the indicator is a matter of operator preference. The universal-mounting bracket (included)
enables it to be mounted to the safety cage or on the truck’s dashboard. Mount the indicator at the
preferred location using the supplied hardware. Run the load cell cable from scale assembly to the
indicator, securing it with cable ties where necessary, but DO NOT plug connector into back of scale
until power hook-up is completed. For most installations the load cell cable is secured with cable ties at
the roll cage and at the top of the mast, however, each installation must be reviewed to determine the
best method of securing the load cell cable. Slowly and carefully raise and lower the carriage and
watch load cell cable for possible pinch points. Make sure there is enough slack in load cell cable if
mast is fully extended. If scale has side shifter see installation instructions for installing side shift
bracket
Note:
4.2.
Lift trucks that are equipped with side-shift require an extra bracket.
Hook up power to the system. The power hook up procedure depends upon the type of lift truck,
gas/propane or electric. Follow the respective steps:
Note:
To avoid damage to the indicator it is necessary to ensure that the indicator is setup
for the corresponding lift truck voltage. This input voltage is preset at the factory per
the customer supplied voltage specification.
4.2.1.
Gas/Propane Truck. Run the power cable (two-conductor) from the indicator to the battery
power supply of the truck. When routing the power cable avoid all contact with any moving or hot
parts of the lift truck. The power cable is normally routed behind the dashboard or under the
floor of the cab. Use wire ties to secure it in a safe position. Make sure all electrical
connections match the polarity and voltage of the battery posts. Power cable inputs are white
(+) and black (-). Ensue power cable is routed away from distributor cap, spark plug coil and
spark plug wires. Failure to route cable away from these noise sources could cause intermittent
operation or damage the indicator.
Note:
Do not use instrument gauges for hook up. Due to internal impedance, this could
cause indicator problems or failure.
Warning:
Lift trucks with ignition systems (gas/propane) require carbon noise suppressed
spark plug wires, and resistor-type spark plugs. Failure to have all parts installed
correctly will damage the scale indicator. Also, copper or stainless wires on ignition
systems will damage the scale indicator.
4.2.2.
Electric Lift Truck. Be sure the indicator is equipped for the proper voltage. Run the power
cable (two-conductor) from the indicator to the battery of the truck. The power cable is normally
routed behind the dashboard or under the floor of the cab. When routing the power cable avoid
all contact with any moving or hot parts of the lift truck. Use wire ties to secure it in a safe
position. Make sure all electrical connections match the polarity and voltage of the battery posts.
Power cable inputs are white (+) and black (-).
Important: Connect the power cable inputs to the first two lugs coming off of the battery power
supply. This will ensure that you are hooked up to a clean power supply and avoid
damaging the equipment.
Warning:
Electric lift trucks do not have a chassis ground. A connection using the chassis as
a ground will damage the scale indicator.
 LTS Scale Company, LLC
15
Rev B 1/26/16
4.3. Plug in the power cable and load cell cable into the back of the indicator. Re-check the safety plates
and fork stop bolts to be sure they are properly secured. Turn the indicator ON and lift the forks off
the ground. Carefully raise and lower the carriage and check the load cell cable to be sure it does not
catch on anything. Use wire ties to secure the load cell cable in a clear position. Press “ZERO” key on
the indicator. The indicator should zero and be ready for use. Forks must be in a level position to
ensure accurate readings.
Do not make any calibration adjustments until the scale has been exercised several times, with a load of at least
50% of capacity. After exercising the scale, repeat adjustment of the carriage alignment bolts.

Service and Repair
5. Flexure Replacement and Adjustment
In order to replace flexures, it is necessary to remove the entire scale assembly from the lift truck. Prior to
replacing the flexures, perform the following steps:
5.1. Make sure the indicator is turned off.
5.2. Remove the forks from the scale assembly.
5.3. Disconnect the load cell cable from the indicator.
5.4. Remove the safety plates from the bottom of the scale and truck carriage.
5.5.
Position the lift truck so that the scale assembly can be lowered onto a sturdy work surface. (A heavy
gauge-shipping pallet works well) Back the lift truck away from the work surface, leaving the scale
assembly on the pallet in a vertical position. Secure the scale so that it does not fall.
6. Top Flexures
6.1. If it is necessary to replace more than one flexure on the scale, be sure to remove and replace only one
flexure (or set of flexures) at a time. When replacing a flexure, it is important to return all retainer
clamps and any shims to their original position.
6.2. It may be necessary to use two large “C” clamps at the bottom to draw the scale assembly together. If
clamping is necessary, do not exert excessive clamping force.
6.3. It may also be necessary to ream holes in the replacement flexures, to prevent bolts in flexure retainer
clamps from binding.
Note: Do not tighten the flexure retainer clamps all the way. Positioning and tightening will follow in
Final Adjustment of Flexure Retaining Plates.
7. Bottom Flexures
7.1. Replacement of bottom flexures is more complex than the top flexures. Most shims used for achieving
heel-to-toe balancing are located in the bottom row of flexures. Carefully remove flexures from the
bottom row and look for shims beneath. Shims must be returned to their original position between
flexure and scale. (Ref. figure: 2)
7.2. After all lower flexures are replaced and shims are in proper locations, tighten all lower bolts on the
retainer clamps, but do not tighten them completely.
 LTS Scale Company, LLC
17
Rev B 1/26/16
8. Final Adjustment of Flexure Retaining Plates
8.1. Place two “C” clamps on the bottom of the plate assembly between center and outer flexures and
tighten the clamps. Locate the two stop-bolts and back them out so they are tight against the front
plate. Check to ensure that all flexure-retaining clamps are flush with the front plate. Do not allow the
retaining clamps to extend beyond the surface of the front plate. When all retaining clamps are flush,
torque all bolts to approximately 125 ft.-lbs.
8.2. After all flexure retainer bolts have been tightened, inspect flexure support clamps to determine that a
gap of approximately 1/16-inch is maintained between both ends of the support clamp and the inside of
the plate assemblies. It may be necessary to either reposition the support clamp, or to remove and
grind (either side of) the clamp to give the approximate 1/16-inch gap. If grinding is necessary, remove
the entire support clamp (top and bottom) and grind together as one unit.
8.3. Inspect again to ensure that no flexures are extending beyond the surface of the front or rear plate. If a
flexure extends beyond a plate surface, grind off until surface is flush.
8.4. Remove “C” clamps and reinstall scale on lift truck (refer back to the installation procedure). Exercise
scale with a load approximately 50% of scale’s capacity prior to calibration and testing.
9. Scale Balancing - Adjusting Heal-to-Toe Shift
9.1. Heel-to-toe or shift in weighing may be adjusted by adding or removing shims between the lower
flexures and front plate. If weight on heel of fork is higher than the weight on the toe (tip) of the fork,
remove shims (if any) from the lower flexure on the front plate, or add shims to the lower flexure on the
rear plate.
9.2. If the weight on the toe of the fork is higher than on the heel, add shims to the lower flexure on the front
plate. One pound of error equals approximately 0.001-inch shim. Heel and toe adjustments can be
performed at all three flexures on the front plate, by moving the forks on top of the flexure being tested
(left, center, and right, respectively). Important: If you add or remove shims, exercise the scale and
reset the carriage alignment bolts.
