Construction machines are machines used in the construction industry to perform various tasks. These machines are used in construction projects for digging, material handling, workarounds, lifting loads and more. Construction machinery reduces construction speeds, labor and increases benefits.

The working principle of construction machines varies depending on each type of machine and its use. But in general, construction machines move depending on the power source and walking mechanisms whose purpose is to use them to perform a particular task.

Many construction machines draw energy from power sources such as internal combustion engines or electric motors. This power source drives the machine's moving mechanisms and starting. For example, hydraulic systems are used in excavators. The internal combustion engine drives the hydraulic pumps and somehow supplies the hydraulic fluid with high components. This hydraulic pressure is used to control the excavator's arms, bucket and other moving mechanism.

Construction machinery is often controlled by operators. The operator steers and moves the machine using joysticks, pedals, buttons or other control controls. These controls perform the desired action by activating certain features or functions of the machine.

Since construction machines have powerful and complex mechanisms, the training and experience of operators is of great importance. Proper use and the use of safe operating principles are critical to both gaining operators' authorization and ensuring peak performance of the machine.
