The most important mechanical parts in heavy machines

Heavy machinery, such as trucks, bulldozers, and forklifts, are used as the basis for transporting heavy loads around the world. In this article, we examine the importance and characteristics of the most important mechanical parts of these machines.


The engine acts as the heart of any heavy machine and helps provide the necessary power to move and do heavy work.

Power, efficiency, fuel consumption, and useful life are among the critical features of an engine.

Gear box

The gearbox helps to regulate the speed and power of the engine and also takes care of increasing the life of the engine.

Acceleration, power, correct performance and correct transmission of power are among the important features of the gearbox.

The brakes

Brakes are critical to the safety and control of heavy machinery and help reduce the risk of road accidents.

Stunning performance, performance in various conditions, and long life are critical features of heavy vehicle brakes.

Battery and electrical system

The battery and electrical system provide the necessary electricity to run electrical systems, lighting, and other activities, among the essential capabilities of heavy machinery.

Power, useful life, stability, and productivity are among the important characteristics of the battery and electrical system of heavy machines.

Cooling system

The cooling system helps to respond to the increase in temperature and prevent the engine from overheating and protects the optimal performance of the engine.

Efficiency, cooling power, stability, and easy maintenance are among the critical features of the cooling system.


Mechanical parts of heavy machines play a very vital role in the efficiency, safety, and stability of these vehicles. The importance of the productivity and efficiency of these parts has a direct impact on the performance and maintenance cost of the machines, and ultimately on the safety and efficiency in the heavy cargo transportation industry.

These components are constantly being developed and improved to provide more standards for the transportation industry and ensure optimal performance.
