ABSTRACT:
The invention pertains to apparatus for tensioning chains as may be used to tie down and position cargo. A pair of elongated members each have an outer end on which a tension transmitting fitting is mounted, and at their inner ends the members are telescopingly interrelated and adjustably interconnected through a resilient impact cushion placed under compression by tension forces transmitted between the members. A non-compressible sleeve prevents overcompression of the impact cushion and the apparatus includes adjustable elements for precompressing the cushion.
