A tarp cover system including a pawl (44) and ratchet (26) mechanism for locking a tarp cover (6) in a rolled-up truck-body-uncovered condition, and a brake operating lever that is initially pivoted in one direction with one hand by the operator to release the pawl from the ratchet to unlock the rolled up cover, and is subsequently pivoted in the same direction by the same hand to brake the unwinding of the cover as it is spring-biased toward the truck-body-covered condition. To re-cover the truck body, a crank shaft (24) is rotated to rotate the roll in the cover-winding direction against the biasing force of the cover spring, the ratchet mechanism preventing uncontrolled unwinding of the cover.

ystème de bâche comprenant un mécanisme à cliquet (44) et rochet (26) servant à bloquer une bâche (6) en position enroulée sur une caisse de camion ainsi qu'un levier de freinage que l'opérateur doit d'abord presser d'une seule main pour libérer le cliquet du rochet afin de déverrouiller la bâche enroulée et qu'il doit ensuite faire pivoter, de la même main, pour freine le déroulement de la bâche que l'action d'un ressort place en position de recouvrement de la caisse du camion. Pour remettre la bâche en position de recouvrement, une manivelle (24) doit être actionnée pour tourner le rouleau et le faire se dérouler contre l'action de rappel du ressort, le mécanisme d'encliquetage empêchant le déroulement désordonné de la bâche.
