What are lifts made of?
Content
blade and shaft
The blade and shaft of a typical hoist are made from a single piece of forged vanadium or carbon steel.What is vanadium and vanadium steel?
Vanadium is a hard, silver-gray, ductile and malleable metallic element.
Vanadium steel is a type of steel alloyed with vanadium for added strength, hardness, and high temperature resistance. Because of the great effort that goes into the lift, it must be made from a strong piece of metal.
What is carbon steel?
Carbon steel is a type of steel alloy with a minimum carbon content of 0.3%. The properties of carbon steel depend on the amount of carbon it contains. There are three main types of carbon steel: low, medium and high carbon. Lifts are usually made of medium carbon steel.
1. low carbon steel
Contains up to 0.3% carbon. This increases ductility, but does not affect strength. Ductility is a measure of how much stress a material can withstand before it breaks.
2. Medium carbon steel
Contains from 0.3 to 0.5% carbon. It is ideal for machining or forging and where surface hardness is desired.
3. High carbon steel
Contains more than 0.5% carbon. This becomes very hard and withstands high shear loads and wear.
What is "forging"?
Forging is a manufacturing process in which steel is deformed (usually while hot) into a desired shape using a compressive force, such as a blow from a hammer.
