2) Using of the emergency pump to check operation conditions of hydraulic system, and mechanical dredging work.
3) After operation of system working condition checked, check engines running and power capacity.

Second, test in testing pool

2) Upon testing completion of electricity system, hydraulic system, engines, and dredging pump, main hydraulic pump will be opened and hydraulic system load performance is tested, in order to check operation of the work of the various hydraulic machinery and systems

Third, install at work site and debug

1) Our technician will go to work site to install dredger.
