1. Special hydraulic telescopic crawler chassis, heavy slewing bearing, high stability of the whole machine;

2. The box boom structure is adopted with good flexibility, which effectively avoids the drop of the verticality of the groove caused by the impact during the grab construction;

3. Imported Cummins EFI turbocharged engine (Euro III) is selected, with strong power, low noise and low emission;

4. Equipped with inclinometer, with functions such as grab deviation correction and touchdown protection, recording and storing the digging process of grab and drawing the groove curve, which can effectively ensure the groove accuracy;

4. Equipped with inclinometer, with functions such as grab deviation correction and touchdown protection, recording and storing the digging process of grab and drawing the groove curve, which can effectively ensure the groove accuracy;

5. The hydraulic motor provides constant tension hose reel control system to ensure that the hose can be automatically lowered and lifted with the grab in the process of slotting;

6. The intelligent control system can realize automatic winding, cable retraction, winch synchronization, automatic detection of pressure and alarm at key points, and reduce service and maintenance time.
