Digital Electronic Frame for Direct Shear Test

It operates with an advanced electromechanical structure that includes a stepper motor, a precise reduction unit, and a lead screw with reduced backlash.

The device is designed to achieve linear, micrometric movements during rapid return motion at a constant speed and independently of the load.

The continuous movement speed in both directions can be adjusted between 0.00001 and 9 mm/min using the electronic control unit.

With the digital display, rotation count, forward/reverse speeds, and displacement can be programmed for direct shear measurement.

Suitable for shear boxes measuring 100 x 100 mm.
