Three-section Telescopic Arm
* Centralized lubrication
* Adopt 30mm main rope, Adopt 26mm auxiliary rope
* Can design to match bucket and grabber
* The upgraded auxiliary rope design makes the pipeline smoother while stretching
* The external hose pulley separates the hose from the main rope, avoids the friction between the main rope and the hose, reduces failures, and makes maintenance more convenient
