CTW Automation presents the RD3 for the bigger rebound “tie-down” shocks.

RD3 is 3HP machine with a peak stroke of 2.0″ and peak speeds over 40 in/sec.

The RD3 uses CTW-Probe Analysis software to allow the user to create and run Tests of various velocities on one of three strokes to collect force data that is presented in various industry-standard graphs. The RD3 is a compact, lightweight tabletop machine that is designed to be structurally sound where loading is applied based on FEA analysis. Measurements are taken based on the line of actuation to ensure only the damper or specimen result is recorded.
