Highlights of excavator sliding boom slding arm
An excavator sliding arm, also known as a telescopic arm or extendable arm, is a specialized feature found on some excavators. It is designed to increase the reach and versatility of the machine by providing an additional telescoping section that can extend or retract.
The sliding arm consists of two or more sections that slide into one another, similar to a telescope. The sections are usually made of high-strength steel and are connected by hydraulic cylinders, which allow for controlled extension and retraction.
When the arm is fully retracted, it functions like a standard excavator arm, providing a shorter reach and digging capability.
However, when the hydraulic cylinders extend the sliding sections, the arm's length increases, enabling the excavator to reach further distances or depths.
This feature is particularly useful in applications where additional reach is required, such as excavating deep trenches, working on sloped terrain, or reaching over obstacles. It allows the operator to adjust the arm's length on the go, without the need for manual arm changes or repositioning of the entire machine.
It's important to note that not all excavators come equipped with a sliding arm. This feature is typically found on larger, more advanced excavator models designed for specific applications where extended reach is a priority.
