Dead-Weight, Direct Residual Shear Machines

The HM-5750 Series of Dead-Weight Direct-Shear machines comes in two configurations — analog and manual gauge measuring devices. These machines feature Humboldt's touch-screen monitor for test control. In addition, Model HM-5750A provides four (4) integral and independent data acquisition channels, which can be utilized in stand-alone configurations or accessed through a LAN-networked computer using Humboldt‘s Next Software for control and data collection.

HM-5750A.3F
The HM-5750A Direct Shear machine is an economical choice for performing direct/residual shear tests utilizing the dead-weight method and analog measuring devices. The microprocessor-based system features a stepper-motor drive system and a 7" touch-screen display that allows the operator to control and monitor all test functions. Like all Elite Series machines, the HM-5750A is built around Humboldt's integral, 4-channel data logger with touch-screen control, which allows the HM-5750A to be used as a standalone device capable of full test control and data logging. It can also be controlled by a networked computer at any location with access to the network. The carriage accepts shear box squares up to 4.0" (100mm) internal dimension. Forward and reverse measurements permit residual shear testing as standard. A built-in safety feature prevents the overloading of the load measuring system. The HM-5750A is supplied complete with a 2,000 lbf (10kN) capacity load cell, 1" (25.4mm) horizontal strain transducer, and a 0.4" (10.2mm) vertical strain transducer.

Shear box assemblies and related accessories are not included and should be ordered separately

HM-5750.3F / HM-5750M.3F
The HM-5750 and HM-5750M Direct Shear machines are an economical choice for performing direct/residual shear tests utilizing the dead-weight method with load rings and dial gauges.
These models include the carriage, stand, vertical load hanger, and a balanced lever loading arm with a 10:1 ratio that reduces the weight required to perform tests. The micro-processor-based system features a stepper motor drive system and a 7" touch-screen display. The carriage accepts shear box squares up to 4.0" (100mm) internal dimension. Forward and reverse measurements permit residual shear testing as standard. A built-in safety feature prevents the overtravel of the load measuring system. The HM-5750 and HM-5750M are supplied complete with a 2,000 lbf (10kN) capacity load ring, 1.0" x 0.001" (25.4 x 0.01mm) and 0.5" x 0.0001" (12 x 0.002mm) dial indicator.)

Shear box assemblies and related accessories are not included and should be ordered separately

Upgrade Your Existing Humboldt Geotechnical Testing Machines to Elite Series Machines
You can upgrade your existing Humboldt testing equipment to our Elite Series machines. These upgrades require your existing machine to be sent to Humboldt for a complete refurbishment and upgrade to the new equipment. Upgrades include the new 7", full-color touch-screen controller, and a new enclosure. (When upgrading machines, return transducers and load cells along with the machine for recalibration.
