Double-ended shear beam truck scales

Diamondback truck scales.
Built to take the hit.

The double-ended shear beam sits in a self-centering mount, so the weighbridge returns to center after braking shock and off-center loading. CheckLink parallel-link suspension absorbs the motion of vehicles starting and stopping. Up to 130,000 lb concentrated load capacity on the 8560XD.

The Diamondback specialty

Impact, and the heaviest loads

Diamondback is the family to specify when the traffic itself is the problem: haul roads, off-road vehicles and the highest concentrated loads of any scale Thurman manufactures. The load path is what earns it that job.

Self-centering load path

The double-ended shear beam sits in a self-centering mount. After impacts, braking shock and side loads the weighbridge returns to center on its own.

130,000 lb CLC on the 8560XD

The Diamondback 8560XD carries a 130,000 lb concentrated load capacity at 135 tons, on 100,000 lb double-ended shear beam cells — the highest concentrated load capacity in the Thurman catalog.

CheckLink suspension

Parallel links give 360-degree shock suspension and absorb the motion of vehicles starting and stopping. The 8560XD adds four end-wall bumper check bolts, set at installation.

Top or side service access

On the 8560, 8550 and 8560 PV, each load cell is reached through a top corner access plate. The Diamondback 8560XD mounts its load cells and enclosures on the side of the weighbridge, so a technician works them from outside the bridge.

5-year weighbridge warranty

The structural steel weighbridge carries a 5-year warranty from shipment against defective material or workmanship, provided it is serviced at least twice a year by a Thurman-authorized service entity under a Preventive Maintenance Agreement that stays in force for the full warranty period.

Load cell interface

Analog or Intalogix®.

Every Thurman electronic scale is configured with one of two load-cell interfaces. Specify an analog interface to combine all the load cell signals into one that is read by the indicator, or trade up to Intalogix for a modern digital solution with the latest in lightning and surge technologies.

Thurman Analog

One summed signal, trimmed section by section.

123
  1. One Analog Section Controller for each truck scale section
  2. Each section is trimmed at a potentiometer on its controller
  3. The controllers interconnect and send one analog signal to the indicator

Serviced with a meter and standard test equipment.

Pairs with the TS3301 and TS3302 indicators

Thurman Intalogix Technology

Every load cell reported, trimmed at the indicator.

1234
  1. One Smart Sectional Controller for each truck scale section
  2. Controllers daisy-chain on a digital path
  3. One pit power supply per scale, with built-in lightning and surge protection
  4. 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.

Pairs with the TS3311 and TS3312 indicators

Analog signalDigital data

One ordering rule. A scale supplied with Intalogix must be ordered with an Intalogix indicator at the same time — the interface and the indicator are specified together. Your distributor confirms which interface a given model ships with at quotation.
