What Are The Advantages Of Two Section Long Reach Arm？
In construction projects such as river channel clean out and slope protection, the standard excavator arm cannot reach far distance working points. As a key attachment for excavators, the two section long reach arm breaks the limitation of working distance and expands the working boundary of excavators. It is the preferred equipment for long distance construction, and customized production is available for different demands.
The most prominent merit of the two section long reach arm is its wide working coverage
Compared with original standard arms, this long reach boom achieves longer digging radius, deeper digging depth and higher uninstall height. For river dredging, the excavator can finish sludge cleaning on the bank instead of driving into water, avoiding sinking risks. For high slope trimming, frequent machine relocation is unnecessary. It can finish slope finishing in one operation, saving time spent on moving machines.
It adopts high strength raw materials for reliable structural performance
The boom is mainly made of Q355D, Q460C or Q550 steel plates with high tensile strength. Under heavy load conditions like earth digging and sand handling, the boom resists deformation and cracking effectively. The pin shaft is made of 40Cr, and copper bush is embedded at the base of the boom. These core components reduce friction during operation, lower abnormal clearance and noise, and extend overall service life for long time continuous outdoor work.
Reasonable pipeline layout guarantees smooth movements.
Equipped with high pressure oil tubes, the arm delivers stable hydraulic oil transmission during stretching, retracting and lifting. Movements are responsive without stuck or delay. Well arranged pipelines reduce hydraulic leakage failures, cut down on site maintenance work and support continuous construction progress.
Customized design brings great compatibility. It can be tailored according to different excavator tonnage, covering 20/25T, 30/36T, 40/47T models. Parameters including arm length, digging radius, bucket capacity and counterweight can be adjusted for actual working conditions. No matter shallow river dredging, high slope trimming or long distance earth handling, customized specifications can perfectly match site requirements.
It improves construction efficiency and cuts comprehensive costs.
The long reach arm enlarges single operation coverage and reduces machine relocation frequency, which lessens wear of track components. Operators can complete tasks from safe distance for risky working spots, lowering potential safety hazards. It also decreases the need for auxiliary machines, saving machine rental and labor expenses.
To sum up, with extended working range, durable materials, stable hydraulic performance and customizable features, the two section long reach arm solves many long distance construction difficulties. It is widely applied in river dredging, slope protection and foundation excavation, bringing great practical value to engineering projects.
