Tower cranes often have more than one pulley. This helps it multiply its force to lift heavy objects. Using the scientific principles behind simple machines, such as the lever and the pulley, cranes can multiply smaller forces to lift heavy loads to great heights.
What makes a crane strong?
The most important substance used to manufacture cranes is steel. Steel is an alloy of iron and a small amount of carbon. For structures that do not require very high strength, a common form of steel known as carbon steel is used. By definition, carbon steel contains less than 2% of elements other than iron and carbon.

How much weight can Cranes lift?
So there is no one simple answer to the question, “how much weight can a crane lift?” On average, most cranes can lift loads between 10 and 60 tonnes. But some models can handle much more weight. Keep in mind that the capacity depends on the specific vehicle and the nature of the lift.
How do Cranes not fall over?
Why Don’t Tower Cranes Fall Over? This is mostly down to the concrete base, which is massive and needs to be poured weeks before the crane arrives. The triangulated cross-member structure of the mast gives it more stability and prevents bending. Plus, it’s anchored and bolted to the ground.
