stout box-type arm, hydraulic system, Cummins QSL9-C325 EFI turbocharging engine-Europe III, Rexroth A8VO variable dual-pump - details see: https://www.machineto.com/xcmg-xg450d-drilling-rig-diaphragm-wall-grab-diaphragm-equipment-10113150

XCMGXG450DDiaphragm Wall Grab

-Adopt the drilling rig chassis made with XCMG’s mature technique and the stout box-type arm frame, which are quite stable. The winch adopts the layout of single rope with front winch and rear winch, attached with advanced electrical and hydraulic system, which greatly improves the service life of the steel wire rope and the system stability.
- The imported Cummins QSL9-C325 EFI turbocharging engine (Europe III) has strong power, low noise and emission.
- Adopt stable, reliable, and high-performance hydraulic system and parts of international brand. The main circuit adopts Rexroth A8VO variable dual-pump as the main pump which composes the load sensing control system with the main valve to obtain energy conservation. The reel system adopts Rexroth Mooring Control constant tension control system with stable and reliable performance.
- The advanced programmable inclinometry device can record and save the digging process of the grab, which can effectively ensure the construction quality.
- Adopt advanced intelligent failure diagnosis system, sounding system, touchdown protection system, and CPC system
