Gilson Dead-Weight Direct and Direct/Residual Shear Machines by Karol-Warner are motorized units for dead-weight direct and direct/residual shear testing of soil samples and use a 10:1 dead-weight beam loading system to apply vertical confining pressures. These compact, self-contained units have similar designs, but differ in instrumentation for data measurement and collection. Both are built for harsh laboratory environments and require little floor space.

Strain rate is precisely controlled from 0.0001—0.3in/min (0.0025—7.62mm/min) ±1% by an advanced stepper-motor drive system. Settings are easily adjusted using digital thumb wheel controls. Maximum shear displacement is 0.8in (20.3mm). Vertical load capacity is 1,411lb (640kg) and maximum horizontal shear force is 1,500lbf (6,672N). A solid 1.25in (32mm) base for the Shear Box assembly is mounted on a sturdy painted steel cabinet and stand with heavy-duty casters for easy mobility. Drainage plates, loading block, and a water chamber of Teflon coated anodized aluminum are included. Round or Square Direct Shear Boxes are available in a variety of sizes and are purchased separately. HMA-739 Shear Box Counterbalance offsets top-half weight of Shear Boxes with specimen dimensions up to 2.5in (63.5mm) and is also purchased separately. Inquire for Counterbalances for larger sizes. Weight Sets are purchased separately, and at least one US or Metric weight set is required for proper operation.

HM-380R Dead-Weight Direct Shear Machine features an S-Type Load Cell with Digital Readout to display shear force, and Analog Dial Indicators to measure vertical and shear displacement.

Options to upgrade the HM-380R for partial or complete electronic measurement and data collection include HM-739 Linear Variable Displacement Transducers (LVDT’s) with 1in (25.4mm) range and 0.0001in (0.0025mm) resolution to measure horizontal and vertical displacement. The LVDT’s must be connected to an HM-418 Two-Channel or HM-419 Four-Channel Digital Readout. The Readouts show real-time values on a large vacuum fluorescent display and can transfer load and displacement data to a computer with a Windows® XP or newer operating system. The HM-419 model provides an additional channel to route force measurements from the Load Cell to a computer. All are purchased separately.

HM-380D Direct/Residual Shear Machine performs both direct and residual shear measurements and is already configured for complete electronic measurement and data collection. Vertical consolidation, shear force, and horizontal displacement values are all processed through a four-channel Digital Readout and routed to the user’s Windows-based computer via a mini USB port. Data can be used for analysis and to create printable graphs. Software is included to plot test progress and import data to an Excel spreadsheet. The digital display shows current values on selected channels.
