A shovel is a tool for digging and moving things. 

Long ago, people used animal bones to dig. They used a shoulder blade as a simple shovel. Today, we have many kinds of shovels for different jobs. Some shovels have wide blades to push snow. 
In the past, many people worked together to shovel. They moved coal and gravel by hand. Later, a man named Frederick Taylor studied how to shovel. He wanted to find the best way to work. He found that different materials need different shovels. For example, you should not use the same shovel for coal and gravel. Using the right tool helps people work better. Now, big machines often do this heavy work.
A shovel is a helpful tool for many jobs. 

Most hand shovels work in a very simple way. 
People have been digging for a very long time. 
There are many special types of shovels to know. 


Today, we use both hands and machines for digging. 
A shovel is a versatile hand tool designed for digging, lifting, and moving bulk materials. 
The mechanism of a hand shovel relies on the strength of its materials. 
Shovels come in many specialized types tailored to specific tasks. 


Humanity has used digging tools since the Neolithic age. In those early times, people often used the scapula, or shoulder blade, of large animals as crude shovels. The development of purpose-built shovels was a groundbreaking advancement for farming and construction. For a long time, manual shoveling was the primary method for excavation in many industries. This included mining, quarrying, and loading railroad cars or cargo holds with ore and grain. Until the 1950s, manual labor was a massive part of these industries. Large groups of workers, known as labor gangs, were assigned to handle digging tasks. These gangs could consist of dozens or even hundreds of workers performing rapid excavation.
In the late 19th and early 20th centuries, the efficiency of this work became a scientific study. Frederick Winslow Taylor, a developer of scientific management, took a deep interest in the "science of shoveling." 
The transition from manual labor to mechanization changed the industrial landscape. During the Second Industrial Revolution around 1900, heavy equipment like crawler excavators became available.
