pin

“pin” in machines is a simple but crucial part. It’s a metal piece, like a cylinder, that connects different parts of a machine, allowing them to move or rotate at joints. Pins vary in shapes and sizes and are commonly found in construction equipment, vehicles, and other machinery.
Where you find a pin on a machine depends on how the machine is designed. In construction equipment, like excavators or loaders, pins are often used in joints that let arms or buckets move. In vehicles, pins might be part of the suspension system or hinge points for doors. The exact spot and role of a pin change based on the specific design of the machine.
