Preliminary results of mean velocities, velocity dispersions and dynamical masses are presented for the galaxy clusters A1750, SC0626-54 and SC0625-536, based on new spectroscopic observations of more than 150 galaxies. Their optical and dynamical structures show that A1750 is dynamically a double cluster, but the other two have single structures, forming together an extended supercluster.
