Kaivurit

Kaivurit, commonly known as excavators, are heavy construction equipment used for digging trenches and holes, demolition, and material handling. They are characterized by a boom, dipper (or stick), bucket, and cab on a rotating platform known as the house. The house sits atop an undercarriage with tracks or wheels. The tracks provide excellent stability and mobility over rough terrain, while wheeled excavators offer greater speed and maneuverability on hard surfaces.

The primary function of a kaivuri is excavation. The hydraulic system allows for precise control of the boom, dipper, and bucket, enabling operators to dig with great accuracy. This makes them indispensable for a wide range of tasks, including building foundations, laying pipelines, road construction, and mining operations. Beyond digging, kaivurit can be fitted with various attachments, such as hydraulic hammers for breaking concrete and rock, grapples for moving scrap or logs, and augers for drilling holes.

Kaivurit are powered by diesel engines that drive hydraulic pumps. These pumps generate the fluid pressure needed to operate the various arm and bucket movements. The operator controls these movements from the cab, which typically offers 360-degree visibility. The rotating house allows the operator to swing the boom and bucket to different positions without moving the undercarriage, increasing efficiency. Their versatility and power have made kaivurit a cornerstone of modern construction and earthmoving.
