Concept of hydraulic cylinder and mechanical superiority.
 The threshold of crane industry has been raised in this years. For some detailed crane information about cranes, you can access the crane service and the RAMHOIST website on the mechanical mobile page.
 Like leverage, scholars have learned from Archimedes's earliest theoretical development. In King Hieron of Syracuse, Archimedes moves on a large ship in the sea of heron. Archimedes set up his pulley system on the appointed day, the ship was full of passengers and goods, and Archimedes pulled the rope. As a result, the goods transported were "smooth and uniform, just like she was in the sea."
 Unlike ancient ways of dealing with people, modern people not only regard this as a novelty, but a basic science. Next, I will explain this principle briefly. In order to make the weight easier to lift, the pulley can distribute weight by different rope. Suppose there is a very heavy object. Someone stretched out his hand and tried to lift it with his own strength. In order to be able to do it, he joined the roller skating on the big load. Then tie the rope at the other end of the heavy weight to the ceiling and pull the rope onto the pulley. Then he can lift the object by raising the rope. Why can we do it? Because half of the force required to lift objects is provided by the  ceiling, and people only pay half of their strength.
 What is the cause of this situation? The weight of the roller skating is distributed on the two rope segments, one side from the ceiling to the pulley, and the other side from the pulley to the lift. Torque controls the distribution. Because we use the ability to lift the ceiling to support the ceiling, the initiates do only half of the work, so whether you believe it or not, the ceiling helps to improve the object. Not only that, the way of increasing the pulley can also make the elevator move, but the physical explanation is more complicated. It can be briefly explained that the general rule is that the number of pulley determines the power.
 The effect of roller skating in different configurations is different. Here are three types of roller skating. The fixed sliding middle axle or wheel is fixed, allowing easier configuration. The movable pulley's center shaft or wheel can move freely, and the movable pulley is multiplied by the additional force, which makes the work easier. Combined pulleys are third  kinds of fixed pulley which can be fixed and movable. Like leverage, different situations require different types of pulleys.
 So what is the way to apply it to a crane? First of all, it is necessary to use pulleys on cranes. The most common thing is to use roller skating in cantilever cranes. Because the cantilever crane is equipped with wires, it can be wound and load roller skating. The lifting capacity depends on the number of packages.
 Next is the importance of hydraulic cylinders for cranes. This is a follow-up article about the advantages of machinery.
 The role of hydraulic cylinders will be linked to the third part of the science behind our series of construction cranes. The first part is the lever, the second part is the pulley, which briefly describes the cause of the lifting force of the crane.
