Truck scales, railroad scales, floor scales and indicators
· Since 1918Born in Ohio.
Built for the heaviest loads.
Thurman builds the whole weighing system, not one part of it: the weighbridge your trucks drive onto, the indicator that reads the weight, the display the driver sees, and the ticket that prints. One distributor quotes it, installs it and calibrates it.

IndicatorsTS3300Analog or Intalogix, with an embedded web server.Three load paths.
Three different jobs.
For impact & up to 130,000 lb CLCSelf-centering double-ended shear beam.
- Recovers from braking shock and off-center loading
- 130,000 lb CLC at 135 tons on the 8560XD
- CheckLink parallel-link suspension
For solid deck design & side service accessRocker column load cells in the tire path.
- IP69K hermetically sealed stainless cells
- Steel deck and field-poured concrete
- 120,000 lb CLC and 14 ft widths on the 8565XD
Above-ground mechanical lever scaleLever-and-fulcrum weighbridge.
- Levers carry the load; one S-type cell converts it
- 70,000 lb CLC on platforms to 80 ft — model 8100
- 8140 S.A.M. sits above ground, low profile, no pit
Diamondback: When loads land off-center and drivers brake hard on the deck
It absorbs the hit, re-centers itself, and is available with concentrated load capacity up to 130,000 lb.
Falcon: To cut long-term maintenance in wet conditions
The load cells are hermetically sealed to IP69K, the standard deck carries no cover plates, and cells are checked and replaced from beside the platform.
Mechanical: When the site specifies a mechanical scale
Steel levers carry the load and a single S‑type cell converts it, so an 80 ft platform has one weighing element to calibrate and service.
Five decisions, one weighing system
Steel deck, concrete deck, or mechanical lever. Above ground or in a pit. The Diamondback's double-ended shear beam with CheckLink and parallel link suspension, the Falcon's rocker column with hermetically sealed load cells, or the workhorse of a mechanical lever system, are fit by site and traffic.
Truck & rail models →The load-cell interfaceAnalog Section Controllers with potentiometers or Intalogix, an on-scale digital solution with enhanced lightning and surge protection. Chosen at order time, because it sets how the scale is wired, monitored and serviced.
Compare the interfaces →The indicatorThe TS3300 weighing indicator runs the scale, prints the ticket, and can be configured for indoor and washdown environments. An embedded web server provides load-cell diagnostics, downloadable records, and a user configuration menu.
TS3300 models →What the driver seesRemote displays put the weight where the driver can read it from the cab: 5 in. digits with a viewing distance up to 300 ft. Traffic signals mount on their own pole for one or two directions.
Displays & signals →The ticket, and the dataPrinters for single, multi-copy, and thermal tickets. Serial, Ethernet, and PLC interface cards supporting EtherNet/IP, Modbus TCP, or DeviceNet communication. Use your browser or download transaction records to a flash drive.

One summed signal, trimmed section by section.
- One Analog Section Controller for each truck scale section
- Each section is trimmed at a potentiometer on its controller
- The controllers interconnect and send one analog signal to the indicator
Serviced with a meter and standard test equipment.
Every load cell reported, trimmed at the indicator.
- One Smart Sectional Controller for each truck scale section
- Controllers daisy-chain on a digital path
- One pit power supply per scale, with built-in lightning and surge protection
- The indicator reads each load cell and section for diagnostics
Digitize each load cell signal at the scale for individual monitoring, with enhanced protection against lightning and electrical surges.

Made for heavy industry
Quarries, elevators, landfills, plant sites and freight yards run scales all day in dust, impact and weather. Each page below matches a deck, an indicator and a display to that duty cycle — with the capacities and ratings to check the fit.
Grain, feed and bulk commodity weighing — inbound/outbound truck flows and accumulation.
Ultra-heavy haul trucks and aggregate, weighed slow-speed or in motion in punishing environments.
Log trucks and forestry loads on self-restoring decks built to take repeated impact.
High-capacity industrial and rail weighing for mills, scrap yards and heavy material handling.
Landfills, transfer stations and scrap yards, where the scale sets the tipping fee on every load in and out.
Ready-mix, asphalt and cement plants weighing raw material in and loaded trucks out, all season.
Fleets, public scales and distribution centers that weigh before dispatch, on a legal-for-trade deck.
Chemical plants, fuel terminals and power stations, weighing through washdown and corrosive dust.
Who installs it, calibrates it and keeps it running
Every Thurman scale is installed and maintained by an independent, factory-trained distributor — the same people who calibrate it and certify it legal for trade. Downtime on a scale stops the gate, so the parts that shorten a service call are specified into the system, not added later.
Factory-trained distributors handle installation, calibration, legal-for-trade certification and emergency repair, from 70 locations in the current directory.
Find your distributor →With Intalogix, the cell diagnostics page identifies a failing load cell immediately, so a technician replaces the cell that failed instead of isolating it by elimination. Readable from a browser on the TS3300.

Thurman started as a Columbus, Ohio machine shop in 1918 and built its first motor-vehicle scale in 1948. Today it's part of the Fairbanks Scales family.
