ABSTRACT:
In a device for simultaneously stressing a group of tension elements in a prestressed concrete member, a common driving source is used for mechanically rotating each of the spindles and wrench sleeves which are connectible to the tension elements. Separate safety clutches are selectively engageable with each of the spindles and wrench sleeves so that individual connection of each spindle to a tension element can be provided and, as the element is stressed in tension, individual adjustment can be provided by the wrench sleeve for each anchor nut on its associated tension element.
