Wheel and Axle
Another way to apply a pre-tensioning load to a Cast Beam member as it dries is to use a Drive Wheel and Axle rather than a hang-
ing mass over a pulley. In the image below, the load is measured with a 100 N Load Cell (PS-2201) and the load limit is 100 N.
Double Pulley and Axle
Use a hanging mass and two pulleys. The second pulley multiplies the load applied to the Cast Beam member as it dries. In the
image below, the load is measured by a 100 N Load Cell and the load limit is 100 N.
