Goodeng International GD1600

Goodeng International GD1600 is designed to enhance the executing mechanism capability , hydraulic system is designed pursuant to large flow and high pressure. The inserting control valve group reacts fast and reduces 40-50% pressure loss in hydraulic system

1. Equipped with twin diesel engines, one or two engines working is realized to meet different conditions, and thus saving energy. If one of the twin engines breaks down, the other one can still be operated to run slowly , which exploits machine’s redundant capability.
2. Rack and pinion transmission for push&pull.
3. Hydraulic system: push&pull, rotation and walking adopt close-circuit system and electro-hydraulic proportional control.
4. To enhance the executing mechanism capability , hydraulic system is designed pursuant to large flow and high pressure. Our self-designed inserting control valve group reacts fast and reduces 40-50% pressure loss in hydraulic system.
5. Detachable ,floating clamp, floating spindle.
6. Enlarged operation cab, adjustable seat, more humanist and comfortable.
7. Electro-control handle, simple and reliable circuit, with high sensitivity.
8. Two types walking systems: vehicle and wire-control , ensuring safety during travelling.
9. Electro-hydraulic united controlling system independently designed and developed, realizes itself adaptive control to different working condition and different geologic strata，improving the efficiency of construction 20-30% .
10. System is configured with both auto-operation and man-operation. Auto-operation could timely adjust the running parameter according to the strata situation and automatically adjust the rig for protection.
11. Rational and effective flushing cooling system ensures reliability and efficiency of system, and extends motor using life avoiding damages.
12. We have strict methods, systems and facilities for cleaning control of hydraulic system, which ensures the its cleanliness, excelling NAS 8, reducing malfunction rate. (According to authoritative statistics, 70% hydraulic malfunctions arise from contaminated hydraulic oil.)
