A most important tool in industries know as jib crane. The crane, which holds the things with the help of a hoist and can be moved upon a rail near a beam is known as jib crane. It is also known as truck crane. Most of the jib cranes has a telescopic boom in different sections. However, it is bonded with a weight of 63 tons and in every different three sections has telescopic beam. With a length of 40m it has been launched. At the end it is connected with a solid structure and an extender arm is equipped with these booms. This extender arm with approximately of 20 meters long is connected with the main crane with a length of 60 m. The different sections are raised to their desired height when these are loaded.
Behind the cockpit operator, different lines of cables made up of steels, run from real for the arm extender and boom can be raised. These different cables have the capacity of supporting the load of 64 kg (Approx). So minimum ten cables can be lifted by 70 ton jib cranes. Thus, these lines can run through this arm extender and the boom, which is bonded with a metal ball of 129 kg, which carries the lines when there is no load upon the hook.
The spear, which is attached with them must have the capacity to handle the load, when it is moved up and down as well as right and left. "Rotex Gear" (turned-able) complete the two rotations per minute under the cockpit of the operator. This bidirectional hydraulic motor drive the rotation is bounding in the cockpit, which is surrounded with a metal cover to avoid accidents. The hydraulic pedal controls those rotations.
Jib crane and the truck cranes are used to carry heavy loads to a great height. While this lifting operation the crane should be stabled. The truck uses the media in a way so that cranes can't be tilt from one side to other because tires do not have such required stability. Hydraulics is used by that media to lift ground around the truck or jib cranes including the tires of truck. To support the legs and shoes they are made up of beams. Sometimes pads are used under the shoes so that they can be able to drive away the force of the load against the concrete and the jib cranes. These are made of wooden planks to create base than actual shoes.
This whole mechanism is used to balance the crane during the lifting operation. At the bottom of the cockpit detachable counterweights are also placed. This balance is to prevent from slanting over during the work. The requires balance is determined by the radius, angle of the boom and weight of the load during whole process. Thus, man makes easy to lift very heavy weight by these important tools, i.e, jib cranes in our life.
