Abstract
A tensioning apparatus for a lashing strap (8) includes a frame (1) having side walls (5, 5'). One end of the lashing strap (8) is fixed to the frame. A spindle (11) is rotatably secured to the frame (1), bridging the space between the side walls (5, 5') and bearing a tensioning lever (17) for winding the lashing strap (8) up from its free end. Ratchet devices that are employed at either end of the spindle (11) permit the operator to select whether a push or a pull on the tensioning lever (17) is to turn the spindle (11). Each ratchet device includes a ratchet wheel (14; 14') fixed to the spindle (11), a ratchet securing mechanism (70) disposed at the frame (1), and a tensioning ratchet mechanism (80) disposed at the tensioning lever (17).
