Model:GDSLADS
Use:Meets ASTM D-3999, ASTM D-5311, and ASTM D-6528 Standards. GDS Large Automated Direct Shear System (GDSLADS) is an electro-mechanical direct shear testing device for large samples, up to 300mm square or round.
Standard:GBT 50123-2019
Product Code : GDSLADS
Standard Direct Shear up to 300x300mm.
Geomembrane Shear test.
Rock Mechanics sample set.
Electro-magnetic shear actuation, only mains electricity required (no hydraulics or pneumatics).
Electro-magnetic normal force application (no hanging weights, hydraulics or pneumatics).
No compressed air supply required.
Built in Loadcells (standard 100kN range but can be interchanged for lower stress tests)
Reversible loading in shear
Automated data logging – testing can run unattended over night and over weekends
Stiff construction to reduce equipment compliance
Multiple sample boxes available to increase specimen throughput
Cylindrical or square samples available
Key features | Benefits to the user |
---|---|
Electro-mechanical actuation: | Only mains electricity required (no hydraulics or pneumatics) therefore reducing the space required and providing a more accurate system. |
Electro-mechanical & normal force application: | No hanging weights, hydraulics or pneumatics. |
Automated data logging (multiple stage tests): | Testing can run unattended over night and at weekends to increase throughput and reduce staff costs. Multiple stage tests can be preprogrammed and saved in GDSLAB. |
Cylindrical or square samples can be supplied, as well as multiple sample boxes: | GDSLADS has the flexibility to test different shaped samples allowing the user greater flexibility of use, along with increased throughput of tests via multiple sample boxes. |
Built in loadcells (Standard 100kN, other ranges can be provided): | Interchangeable loadcells allow lower range loadcells to be used for more accurate low stress testing. |
Stiff construction: | To reduce equipment compliance and increase accuracy. |
After setting of shear gap no further user intervention is required: | Automated test control and a greater throughput of samples. |
Actuators | 100kN Shear force actuator, 100kN Normal force actuator |
