These two challenges are urban congestion and arid areas.That the best solution is the crawler telescopic crane. The reason this crane was used as a solution is that it can carry weights at high altitudes. Also, it can move on the sand and rough surfaces (arid areas) with ease.
The boom comprises many tubes fitted inside one another that can be extended through hydraulics so that weights can be carried over long distances. Telescopic cranes offer a very speedy set-up, making them perfect for emergency or rescue jobs.
Crawlers have fantastic off-road capabilities and portability. They move with ease over rugged or uneven surfaces. The crawler crane does not lose control while lifting and moving heavy loads because it possesses a counterweight.
Therefore, the crawler telescopic crane is a crane with all benefits which were said before. Essentially, cranes are made of steel. Steel consists essentially of iron, manganese, and carbon. The crane will be made from a collection of substances. The crane consists of Medium Carbon Steel which composes of 0.29% - 0.54% of Carbon with 0.60%-1.65% manganese. In addition to its favorable effect on the corrosion resistance of steel, nickel is added to steel to increase hardenability.
Nickel enhances the low-temperature behavior of the material by improving the fracture toughness. Also, solar cells will be added to benefit from the light of the sun and convert it to energy to move the crane and the boom, so, it will be put in a field close to the crane or spread over the body of the crane. We will use the pullies also because the pullies can lift the loads with low effort, so it will decrease the effort of the engine of the crane.
1- The “Torque” concept was used to balance our prototype using the law of: “T= r*F sinθ”. In addition to use the “Six trigonometric ratios” concept and the “Sine law” and “Cosine law” to find the angles in our crane and the lengths of the base and other parts.
