### Construction Crane (Grúa de construcción)

1. 1. 6º “N” Mecánica Industrial, Turno MATUTINO CENTRO DE BACHILLERATO TECNOLOGICO Industrial y de servicios N°26 PROYECTO INTEGRADOR:
2. 2. • LOPEZ VAZQUEZ MARIO ANTONIO • RAVELES EVIA JOSE ALEJANDRO • REYES CAÑAS FELIPE DE JESUS • ZARATE GARCIA CARLOS EDUARDO
3. 3. JUST TAKING knowledge of mechanics, physics and drawing. APPLIED TO ONE PROJECT KNOWLEDGE we have achieved over three years. WHAT WE WILL MAKE A construction crane IS LIMITED TO SCALE. THE PROJECT TO MAKE be based on BOTH LEARNING WORKSHOP mechanics and technical drawing AS ALSO APPLYING THE PHYSICAL AND WHAT ARE THE ESSENTIAL Mathematical Methods.
4. 4. Construction crane runs through a pulley system 4 has pulleys, a counterweight that manages to create a balance forces are equal to 0 this causes the crane can be stabilized and will not fall sideways. a central and mainstay preventing not too quantitative easing move and a larger base that distributes the weight and the forces exerted.
5. 5. • A pulley is a wheel having a slot or groove in its periphery, which rotates about an axis through its center. • a) Fixed pulley: As the name suggests, consists of a single pulley which is fixed somewhere. • b) Movable pulley: A set of two pulleys, one of which is fixed, while the other is mobile.
6. 6. • c) Pulleys composite systems: There are multiple pulley systems that seek to obtain a high mechanical advantage, ie, raise heavy weights with low effort. • In its formula involved the "force" that the object or person must apply to lift the "resistance" and the number of mobile pulleys involved in lifting strength:
7. 7. • "System is in static equilibrium when the total or resultant force (net force) acting on a body and the resulting moment are null, apply for bodies at rest or in constant motion."
8. 8. •  Balance  system:  You  can  say  that  the  balance of translation is achieved when all  summations of the forces is zero (0).  ∑F= 0 • Balance  of  rotation:  You  can  say  that  this  balance  exists  when  summations  of  M  (Moments) is zero (0).                ∑ M= 0
