Three-section telescopic boom for excavators

An excavator with a telescopic arm, also known as a telescopic boom, is a type of construction equipment that combines the functions of an excavator and a telescopic crane. It is designed to provide increased reach and versatility in various construction and excavation tasks.

The telescopic arm or boom of an excavator is equipped with multiple sections that can extend or retract, similar to the telescopic mechanism of a camera tripod or a car antenna. These sections are usually powered by hydraulic cylinders, allowing for smooth and precise movement.

The main advantage of an excavator with a telescopic arm is its extended reach. By extending the boom sections, the excavator can reach greater distances horizontally or vertically, depending on the configuration. This makes it particularly useful in tasks such as digging deep trenches, reaching over obstacles, or working on elevated surfaces.

The telescopic arm of an excavator is typically controlled by the operator using hydraulic joysticks or controls in the cabin. The operator can extend or retract the boom sections as needed, adjusting the reach to match the requirements of the job.

Three-section telescopic arm
The main material we use is Q690/HG785.
Lighter and stronger

The main material of the arm tube is Q690D/HG785.
Longer service life, lighter weight and stronger.
Elsewhere, we use Q355B.

Telescopic arm
Nylon material reduces wear and tear
Our pulleys are made of POM material, which has high mechanical strength and rigidity.
Two pulleys are at the top and the other two at the bottom, which partially separates the high and low sections.
Pressure hoses and wire ropes reduce mutual friction. Reducing the friction will prolong the service life. You can see the wire rope at the top on both sides and the high pressure hose at the bottom. There is also an adjustable bracket to tighten the hose as needed.
