    The construction truck with two levers train, is a tool for the construction of houses formed by a box (13) to load the objects (14), bricks and cement especially, the box (13) is widened, both sides, in what forms the two long radii (1) of the first lever (1-3), which rest on a transverse axis (2) and extend into a short radius (3) that comes into contact with the end of the long radius (4) of the second lever (4 - 6), at the end of which the short radius (6) has a vertical axis (7) with support (8), which will push up the long radius (1) of the first lever (1 -3), -and, with it, to the box (13) loaded with objects (14) -, when the end of its long radius (4) is pushed down by the end of the short radius (3)) of the first lever (1 - 3).

    Construction forklift, with two levers train.
    Object of the invention
    The main objective of the present invention is to reduce the weight of the objects (14) that are loaded in the boxes (13) of the trucks used in construction. In this way, the worker who uses it will stay cooler after the jomada than if he spends hours carrying the usual weight of everything they put in the box (13) of the truck, which is usually a considerable weight that with the passing of the hours the forces are undermining.
    Background of the invention
    The main antecedent of my invention of the day (19.03.17) is in the principle of lever of Archimedes of which, in this occasion, it is duplicated in two levers (1-3) and (4-6), so that it increases the force of the worker at the time of loading with his objects (14), or, what is the same, so that this worker reduces to the maximum his effort at the time of having to lift them and transport them especially.
    Description of the invention
    The construction truck with two levers train, is a tool for the construction of houses, which is formed by a train of levers, in which, the end of the short radius (3) of the first lever (1-3), is in contact with the end of the long radius (4) of the second lever (4-6); each lever (1-3) and (4-6) rests on a transverse axis (2) and (5). The first lever (1-3) has a long radius (1), a pivot or transverse axis (2), and a short radius (3), the end of which contacts the end of the long radius (4) of the second lever (4-6), in which there is another pivot or transverse axis (5) and a short radius (6), whose end bends to form a vertical axis (7) that has a support (8) at its upper end, which is located below the long radius (1) of the first lever (1-3). The support (8) is not fixed to the long radius (1). The long radius (1) is part of the box (13), which in figure 1 is loaded with objects (14) -, from which it protrudes from the sides. The transverse axis (2) joins the other long radius (1), - located at the bottom of the blade -, which is parallel to the long radius (1) seen in the foreground. At the center point of this transverse axis (2), the upper end of another vertical axis is located
    (9) at whose lower end the wheel (11) is located. Of this vertical axis (9), and, fixed to it, they extend to both sides, and, horizontally, two rectangles, which cannot be seen in the figure because one is directed towards the reader, and, the other, towards the bottom of the sheet. From them, two other parallel metal rectangles (10) start, in whose vertical edge, -which is parallel to the axis (9), and, in the figure, is located on its right-, they have a transverse axis (5), -of the that, in figure 1, only the outer end is seen, which functions as a pivot for the second lever (4-6), whose short radius (6) bends vertically on the axis (7). A "V" shaped support (12) is located below the box (13), and, it serves for the truck to rest on the ground when it is in the rest position.
    Description of the figures
    Figure 1: Side view of a truck loaded with objects (12), in which the position of the two levers (1-3) and (4-6) located in an inverted position with respect to each other can be seen. The second lever (4-6) has a vertical axis (7) with a support (8) at the upper end, which pushes below the long radius (1) when the short radius (3) of the first lever (1-) 3) push down the long radius (4) of the second lever (4-6).

    Description of a preferred embodiment
    The two-lever train construction truck is characterized by being a tool for building houses formed by a box (13) to load objects (14), bricks and cement especially. The box (13) widens, on both sides, in what forms the two long radii (1) of the first lever (1-3), which rest on a transverse axis (2) and extend over a short radius (3) which comes into contact with the end of the long radius (4) of the second lever (4-6), at which end of the short radius (6) has a vertical axis (7) with support (8), which will push up to the long radius (1) of the first lever (13), -and, with it, to the box (13) loaded with objects (14) -, when the end of its long radius (4) is pushed down by the end of the short radius (3) of the first lever (1-3). The operation can not be easier. When the worker lifts the end of the long radius
    (1) of the first lever (1-3), the end of its short radius (3) will push down the end of the long radius (4) of the second lever (4-6), which will pivot on the transverse axis (5) and will lift with greater force to the end of its short radius (6). In turn, this short radius (6) will push up the vertical axis (7), whose support (8) will push up the long radius (1) of the first lever (1-3), thus reducing the entire weight of the objects (14) that had been placed on the box (13). The separate calculation of the force that can be found at the ends of the short radii (4, 6) of the two levers (1-3) and (4-6) is as follows, for an initial labor force of 30 Newtons , in a long radius of 50 centimeters, and, a short radius of 15 centimeters in the first lever (1-3), and, a long radius of 50 centimeters, and, a short radius of 3 centimeters in the second lever (4 -6):
    In this result we observe that, the downward force of 30 newtons of the weight of the objects (14) that the worker would have to lift with a force of the same value, becomes, on the vertical axis (7), an upward force of 1,666.6 Newtons, which shows that the weight reduction will be more than effective in this truck with two levers, which the worker will appreciate at all times using it.
