The manual traction / compression stand
The MDD Stand is a precision manually operated stand that is easy to use and allows a dynamometer to be moved regularly when hand hold is no longer sufficient.
The rotation of the crank at the top of the stand is the element ensuring the regularity of traction and compression.
The irreversibility of the endless screw within the cross member makes it possible to maintain the force on the part during the test.
This device is very popular for testing springs in association with a digital ruler.
