Digphragm wall grab XTC80/55


Please call : 0086-13916689101



1. Front/rear single rope and dual winches, which substantially improves the rope’s,longest 80m.

2. The specific extra-wide chassis manufactured with XCMG’s mature technologies ,having large swiveling bearing,provides super stability. Max. Distance between tracks: 4900mm.

3. The slewing mechanism is adopted with imported elements, super large slewing support improve the reliability of the grab. The platform is designed through 3D software-aided force analysis, stress analysis and rational layout.

4. The control system of Double winch equipped with an encoder ensures the accurate synchronization of double winches reduces the frequency of synchronized adjustment and increases the construction efficiency.

5. Adopting import double-speed gear box, main winch can accurately control trench cutter’s quick up-down motion and low speed feed. Electro-hydraulically proportional follow-up control system can ensure the synchronism of slurry hose drum, hydraulic hose drum and main winch.

6. Air lift reverse circulation slagging mode, which can reduce the consumption of fuel & construction costs effectively.

7. Self-developed milling wheel-drive structure, easy to get the spare parts, low cost and short time of maintenance.

8. With the convenient function‘one machine, two configurations’, which can achieve universal with XG600D.
