RATCHETS
No. Tensioning devices should only be tightened by hand. Your lashing device is designed for a manual force of 50 daN (20 daN for strap widths of 25 mm). If you increase the leverage of your ratchet, for example, by using a bar, you also increase the tension in your lashing strap. If this force becomes too great, your lashing device will be overloaded, and safety cannot be guaranteed.
For safe use, you must always consider the information on the label of your lashing strap and the LC inscription on your ratchet.

First, calculate the force that you need to absorb. Based on that, you can determine the number of ratchet straps (with a specific breaking strength) you need. Depending on that, choose the ratchets with the appropriate breaking strength.

Standard Push Ratchets
Push ratchets are tensioned by pushing the ratchet lever. This is the standard type of ratchet.
Ergo Ratchets or Pull Ratchets
Ergo ratchets are tensioned by pulling. This makes it easier to transfer the force onto the lashing strap. Unlike traditional ratchets, the ergo ratchet also has an additional strap guide. To tension a pull ratchet correctly, the lashing strap must always be passed UNDER the strap guide.
Ratchets with Short Handle
Standard ratchets come with a short handle. These tensioners can achieve a preload of 200 to 450 daN.
Ratchets with Long Handle
With a longer operating lever, you can apply more preload force (STF) to the strap with the same amount of muscle power compared to ratchets with a short handle. Tensioners with long levers can achieve a preload of 300 to 600 daN. This may vary the number of required ratchets.
Detachable Ratchets
Every ratchet consists of a base element (or console) and a ratchet lever. In detachable ratchets, both elements can be disconnected. After securing, the operating lever can be removed so that only the console remains on the strap. One lever can operate multiple consoles.
