The drum brake system is a mechanical system that generates friction by pushing brake shoes against the rotating inner surface of a drum attached to the wheel, thereby slowing or stopping the vehicle. It is commonly used on the rear wheels of vehicles, integrated with the parking brake mechanism, to provide safe parking functionality. Structure and Operating Principle In this system, a hollow, cylindrical component called the drum rotates with the wheel hub. When braking is applied, the hydrauli

Dump trucks are cargo vehicles equipped with mechanical or hydraulic dumping systems that allow the transported load to be discharged at an angle from the rear or side. These trucks are commonly used for transporting bulk materials such as soil, sand, gravel, excavation debris, and coal. Due to their faster unloading capability compared to fixed-body trucks, they play a vital role in construction, mining, and infrastructure projects. Historical Development The modern form of dump trucks began to

Mobile crane is a lifting and handling machine that operates via a hydraulic system, typically featuring a telescopic boom structure, and can move on roads or terrain without being anchored to a fixed foundation. These machines are equipped with their own chassis, enabling them to move independently, become operational in a short time, and safely transport heavy loads in both vertical and horizontal planes. The primary distinction between mobile cranes and fixed cranes is that mobile cranes are
