What is a telescopic arm for excavators?
A telescopic arm for excavators consists of several key components: a fixed body, a sliding body, a steel wire rope, and a telescopic cylinder. By modifying the sliding bodies, it is possible to achieve a desired working radius and vertical reach for excavation. When paired with a bucket, it effectively handles deep excavation projects like digging up earth, sand, or coal.
Advantages of telescopic arms:
2. We use 6mm thickness.
3. The slider is made of nylon and the pulley is made of steel.All hoses are centrally lubriPCed.
4. The external hose pulley of the bucket cylinder is more convenient for hose replacement and repair.
5. The external hose pulley separates the hose from the main rope.Avoid friction between the main rope and the hose, reduce failures.
6. The double rope design ensures the safety of the telescopic arm. Even if the main rope is broken, the arm will not stretch.
