It is equipped with special chassis manufactured with mature XCMG technologies and it has solid box type boom, featuring extra stability. The reasonable allocation of winch system, combined with advanced electric and hydraulic system, greatly improves the service life of steel wire rope and the system stability. The grapple adopts simple structure and it is convenient for disassembly and repair.
It adopts imported Cummins QSL9-C325 electric-injection turbocharged engine (Euro III) which features strong power, low noise and low emission.
The hydraulic system and parts utilize products of world-famous brands, which feature high stability, reliability and high performance. The main circuit adopts Rexroth A8VO variable displacement dual pump as the main pump, which composes the load sensing control system together with the main valve, and it features energy-saving. The winch system adopts Rexroth Mooring Contrl constant tension control system, which has stable and reliable performance.
The advanced programmable angle measuring device can record the grapple’s working process, which can effectively meet the work requirements and guarantee the work quality.
It adopts advanced intelligent troubleshooting system, depth sounder, touchdown protection system and deviation-rectification system.
