An automatic tarp tensioning device operable to remove slack from a tarp cov er due to stretching and wear includes an extension mechanism attached to a tar p cover and an adjusting element attached to the tarp cover and movable relati ve to the extension mechanism to apply tension to the tarp cover. A plurality o f biasing mechanisms is disposed between the extension mechanism and the adjusting element to bias the adjusting element away from the extension mechanism to thereby tension the tarp cover. Each biasing mechanism includes a spring under compression between the extension mechanism and the adjusting element and a limiting element to limit the maximum extension of the spring. The limiting element includes a bolt and nut assembly interconnecting the extension mechanism and the adjusting member and is adjustable to control th e expansion of the spring. The device operates to automatically tension the ta rp cover when the cover is deployed.
