Wire tensioner for grape trellis
A wire tensioner for grape trellis is a handy tool that greatly facilitates the process of tensioning the wire. It allows you to pull the wire quickly and easily, even if you have no experience in this matter.
A grape trellis wire tensioner is a special device used to tension wire or cable on a trellis.
A wire tensioner is an important element when growing grapes on a trellis. The requirements for the tensioner are simple - load bearing capacity, durability, ease of use, ease of use.
What is the difference between wire tensioners for grapes and tensioners for an intensive garden or tensioners for raspberries, currants and other bushes?
First of all, it should be noted the mediocre loads in the grape row, where with the longest industrial row of 120 meters, the harvest is about 350 kg, and the height of the trellis is 1.8 meters in height.
What are the tasks facing the tensioner for grape trellis? The main task is guaranteed load bearing. All tensioners in our category are suitable for this. So let's move on to additional tasks.
So, we will need three tasks in the work: to fix the wire, to tighten and to fix the tension. Taking into account these three actions, we can divide wire tensioners for grape trellis according to the way they work:
1. Tensioning is carried out using threading according to the lanyard principle. And here, depending on the length of our grape row, which is directly related to the load, you can choose a lanyard from M6 to M14, it is preferable to use the ear-ear or ear-hook type.
When working with a lanyard, we will have three twists from the wire. The first twisting of the wire is for attaching one part of the lanyard to the post, the second is for attaching the second part of the lanyard, and the third twist is for attaching the wire to the remote edge post. Why do we focus on this? First of all, twisting can be an unreliable fastening if you did not make enough turns or did not twist well enough. Secondly, if you did everything well, then you should remember the time spent on these three twists. By the way, the middle twisting should be done last, so as not to guess with the size of the wire. It should also be remembered that the lanyard is limited by threading at the degree of tension, and also from a financial point of view, only m6 and m8 sizes remain attractive.
From all of the above, we can draw conclusions about the advantages of such a tensioner for grape wire as a lanyard:
- availability in every hardware store
- Option to choose with a low price
- absolute clarity of work
- tension fixation does not require additional action
2. Wire tension is obtained by winding the wire on a bolt, square or wire rod.
On the bolt: U-shaped tensioner, clamps for posts - as a feature, there are stoppers for fixing the tension, which is not always convenient to do it yourself. The U-shaped tensioner also requires a separate attachment to the post, which can be done by twisted wire or screw clamps or banding tape.
On the square: the L-90 tensioner is structurally designed in such a way that the stopper is designed on the square itself and stops at a small turn. L-90 is also designed for additional attachment to the pole.
On the wire: Tenvit – a hook or clip made of wire for winding the wire on the vine trellis. In tenvita, a hook is used as fixation, but due to its single position, it can be used only twice during a 360-degree rotation.
3. Griple-type tension, where the level of wire tension depends on the passage of the wire through the griple lock, and the level is fixed at the same time due to the wedging drum. And this tensioner completely lacks twisting of the wire. The tension is fixed automatically. Fairly reasonable price.
However, there are also disadvantages:
- hard to find
- the working principle is not clear at first
- without an additional expensive tool, tensioning is performed only by manual and not always sufficient method
- difficulties with repeated application
