ABSTRACT:
Apparatus for prestressing a concrete structure or the like by wrapping tensioned wire around the peripheral wall of the same includes a carriage which travels about the periphery of the structure, a device mounted on the carriage for paying off wire from a wire supply, a wire tensioning mechanism which includes at least one pair of stress wheels each of which the wire at least partially encircles, a tensiometer, a tensioned wire payout device which is adjustable to pay out wire at selectable heights relative to the carriage, a slip clutch linked to at least one of the stress wheels and being adjusted to slip when torque transferred from the tension in the wire is applied to the clutch and exceeds a predetermined torque value thereby allowing the tension in the wire to be controlled, and a driving motor mounted to the carriage to propel the carriage about the periphery of the structure.
