1. Structure composition: The three-section telescopic arm is the same as the log collecting arm, and the telescopic arm usually carries a clamshell bucket or GP bucket.
2. Product details: The telescopic arm can be made of Q690D-Q960 material according to the requirements, with much deeper excavation depth, simple and convenient operation, safe and reliable.
Twin-Rope Lines
The twin-rope lines are adopted for safety. Even if one of the twin ropes breaks, the other can hold the telescopic arm in position. To evenly distribute the load to twin roles in normal operation, an equalizer is provided to extend rope life.
Free-Fall Prevention Devices
Free-Fall Prevention Device: The clamshell is operated by twin-rope lines for its pull-up operations. Even if one of twin ropes breaks, the other can hold the clamshell to avoid its free fall
The long service life is ensured by using larger-diameter sheaves on the telescopic arm to reduce its bending force. To this end, sheaves and wire ropes are newly attached on the outside. This configuration is convenient for checking if the telescopic arm extends and retracts normally in daily maintenance Extended Rope Life
Rope replacement intervals: 1800 hours
Note: Rope replacement intervals vary according to operating conditions.
