27-WF2060 Digishear, direct/residual shear machine, digital control and display of speed
110-240 V, 50-60 Hz, 1 ph.
STANDARDS: ASTM D3080 / BS 1377:7 / AASHTO T236
General description
This new machine, which is driven by a high resolution stepper motor and worm reduction unit, can accommodate all standard specimens up to 10 cm square and 10 cm dia. The vertical load is directly applied to the specimen through a load frame carrying weights and can be increased using the beam loading device, used to amplify the vertical load on the shear testing machines. It can receive up to 50 kg of weight so that the total load on the specimen can reach 500 N or 5000 N.
Specifications
- Speed range adjustable from 0.00001 to 4.99999 mm/min (preset via firmware)
- Maximum shear force : 5000 N
- Maximum vertical load : 500 N/5000 N using 10:1 lever loading device
- Speed drive ratio : stepper motor 1/10,000 resolution
- Horizontal travel : preset via firmware up to 19 mm
- Displacement limits controlled by optical safety switch
- Digital display : LCD 4-row by 20 characters. Easy to operate via the membrane keyboard
- Overall dimensions : 953x387x1180 mm
- Weight approx. : 120 kg
Shear Boxes
All shear box assemblies are constructed of brass and are designed to contain water that surrounds the specimen. They consist of a square box with a rigid walled round or square hole complete with adapter loading pad, retaining plate, 2 grids, 2 perforated grids and 2 porous plates.
