Abstract
Apparatus for applying a releasable tension to an anchored strap extended over, or connected to, a load carried on a platform. The apparatus comprises a housing, a torsion element for strap recoil, a winching rotor for operatively interconnecting the torsion element and the inboard end of the strap, and a nonincremental clamping assembly for releasably engaging the middle of a strap between the ends. Tension is first supplied to the anchored strap by action of the torsion element on the rotor. Thereafter, further tension is applied to the anchored strap by a winching force applied to the rotor. The tension of the anchored strap is maintained by engagement of the clamping assembly with the strap.
