The main function of the excavator boom cylinder is to control the digging and loading actions of the bucket.
The excavator boom cylinder is an essential component of the excavator’s working mechanism, enabling various actions of the excavator through the principles of hydraulic systems. Specifically, the boom cylinder is connected to a long arm attached to the frame, commonly referred to as the boom. The boom cylinder, controlled by the hydraulic system, allows for the digging and loading actions of the bucket, achieved by regulating the inflow and outflow of hydraulic oil to control the extension and retraction of the boom.
The working principle of the hydraulic system is based on the hydraulic pump distributing fluid through a distributor, which then flows to the hydraulic inlet and return pipes of the boom cylinder. Since all cylinders on the excavator operate in both directions, there are two boom cylinders, with the inlet and return pipes split into two parallel lines, each connected to one cylinder for both inflow and outflow. This design allows the hydraulic system to efficiently and accurately control the movements of the boom, enabling a series of tasks such as digging and loading.
In summary, the excavator boom cylinder, through precise control of the hydraulic system, facilitates the flexible operation of the excavator’s working mechanism and is one of the key components enabling the excavator to perform various tasks.
