Normally, insiders call it as hydraulic excavators. excavator boom cylinder as one of the hydraulic cylinders, it is widely used in construction machinery industry. Certainly, it’s also an important actuator in the hydraulic transmission system. At the same time it is an energy conversion device that converts hydraulic energy into mechanical energy.

Types Of Hydraulic Cylinders

Depending on the application and industry, we also call hydraulic cylinders as hydraulic actuators or hydraulic pistons. Pneumatic actuators are often used to control processes that require accurate and fast response. This is because pneumatic actuators do not require large power. However, hydraulic actuators have a variety of directions, but the most common is the piston type. Meanwhile, these hydraulic excavator boom cylinder can be of different sizes. Additionally, excavator cylinders own different uses according to different sizes.
