THE CRANE

GENERAL OBJETIVE

 

Vamos hacer el proyecto como una solución a la contaminación de las partes más afectadas en marinilla debido a las inundaciones o desastres que se puedan presentar.

Este proyecto abarca todas las zonas aledañas al río marinilla debido a que las inundaciones que se producen en épocas del año afectan mucho los recursos y principalmente a las familias que viven cerca de este.

We go to make the project like a solution to the contamination of the most affected parts in marinilla due to the floods or disasters that can be presented.

This project embraces all the boundary areas to the river marinilla because the floods that take place in times of the year they affect the resources a lot and mainly to the families that live near this.

 

•Ayudar a la población de marinilla con la contaminación causada por el desborde del río marinilla.•Hacer un rápido trabajo de recuperación de recursos cuando dicho desborde suceda.•Controlar los desbordes por medio de implementos de prevención.

• Help the population gives marinilla with the contamination caused by the overhang of the river marinilla.• make an express work gives recovery of resources when this overhang happens. •control the overhangs by means of implements gives prevention.  

SPECIFICS OBJETIVE

JUSTIFICATION

 

Vamos hacer este proyecto porque vemos que cuando pasan las inundaciones muchas personas quedan afectadas enormemente con todo lo relacionado con sus implementos de casa  y también porque los desbordes que son efectuados por la creciente del rió marinilla causan malos olores en todos sus alrededores y este produce una marinilla desagradable.

Este proyecto lo haremos para que las familias no pierdan todos sus enseres y que vean que la gobernación los apoya.

We go to make this project because we see that when they pass the floods many people they are affected vastly with all the related with their implements of house and also because the overhangs that are made by the growing one give the river marinilla they cause bad scents in all their outskirtses and east produces an unpleasant marinilla.    This project will make it so that the families don't lose all their tackles and that they see that the government supports them.  

HISTORY

Crane, machine to displace vertical heavy objects and horizontally. The capacity gives a crane can go from some hundreds of kilograms until several hundred of tons; the motive power can be manual or to proceed gives electric motors, of internal combustion or give vapor. As for their form, they are classified as cranes of davit, jib cranes motive and cranes bridge. The cranes give davit they take an arm or horizontal davit located on a vertical tower. The horizontal movement gives the load it is gotten rotating the davit or the whole crane and displacing the lathe is hoisted, located in a mobile car that runs along the arm. The mobile jib crane has a design hof cantilever and it is formed by an arm articulated by the base with the inferior part of a vertical mast and I hold in the end by means of a cable that goes to a lathe located in the upside of the mast. To avoid that the mast falls toward the side of the arm counterbalances or suspenders they are used. The horizontal movement is obtained rotating the crane and getting up or lowering the arm. The cranes bridge are formed by a horizontal davit whose ends move on raíles or perpendicular rails to the davit. The lathe is hoisted of slips in longitudinal sense for the davit by means of a car. The cranes normal bridges move on high raíles, while the calls portal cranes are mounted on pillars that move for raíles located at the level of the floor.  

THEORETICAL MARCO

 The first car gives two wheels he/she gives the one that one has news he/she appears in Mesopotamia of B.C. approximately the year 2000. Later on the Egyptians, Persian, Assyrian, Roman and most gives the towns or groupings of the antiquity they used these cars to the being speedier vehicles they were of great importance in times of war transporting in them to the lancers and archers. In the Roman type of these carriages the cars of they drove from behind and they were closed for before and they were discovered cars. They were thrown by three or four horses transported an or two people both of cause. The denominated car “BIGER” it was thrown by two horses and it was used for the battle or for the competition. The compound number “BRIGA” it was thrown by three horses. When the Romans entered triumphant of a battle they used an armored car and closed by all their sides and their panels were decorated with lathes made in copper or in wood. In blunt the career gives carriages it was par excellence the sport in that time.   The Greeks and the Romans have left perseverance of their inventions related with the cranes many of those inventions of those times we use them today in day like the pulley is used more than everything in countries like great Britain, France, Italy, Japan, and other countries. The first crane arrives in great Britain in the century v before Christ.

AND OF ASSEMBLY

PROCEDURES

1.A rain gives ideas with respect to the problems of marinilla 2.The best five problems are taken out 3.And lastly the problem is taken out that will elaborate 4.Then the possible solutions to the outlined problem 5.Then at the most important factors are looked of the project, the cost, the time that takes to elaborate it, and of course the creativity 6.Then spends to make the textual project with all the related with the project: cover, I title, justification, general objective, specific objectives, I mark theoretical, etc. 7.Then the appropriate materials are looked for for the project and you begins to elaborate with the briefings of the designs elaborated in the textual project 8.After the project this elaborated one is begun to look for improvements for the same one 9.Then he/she gets ready the exhibition he/she gives the project with billboards, portfolios, and of course the device
