1.3 It`s really easy to use, because the handles can be located near the object and in the middle.
The negative aspect is that is very thin so if the weight in the box is not balanced, it is going to fell down to one side.
1.4 It’s easy to put a box over the belt you just have to lift up very little the box to put it over the belt. It`s really simple and easy to use, you just have to make two steps to carry a box, the problem is that is really thin so it`s easy that the box lean to one side.
1.5 It doesn’t matter if there is more weight in one side of the box, with this system all the weight is balanced. It can carry a lot of things not only boxes.
1.3 and 1.4 are very resistance so now we are going to look for resistance materials to use in 1.5.
1.3 and 1.4 are really compact and light.
In 1.5 we have to found a way to carry the boxes always in the middle.
In 1.3, 1.4 and 1.5 the time compared with 1.2 and 1.1 is less, because it works in two steps.
In 1.5 we have to find a way to use less handles, and that these handles work property being in the middle of the box always.
We have to use a resistance textile, so Henk can carry 25 kg without breaking the handles.
1.3 and 1.4 are complicated to use, 1.5 speak for it self, you just see it and you can understand how to use it.
Henk like the 1.5 idea, but with some adaptations that we have to make, he like that is compact, and easy to use.
