FAQ
Q: How does Liugong 777A take into account the dual needs of loading and excavation?
A: Through the patented quick-change system (3 minutes switching) and dual-mode optimization design:
Loading mode: 5T rated load + 3.0m³ large-capacity bucket, suitable for ore/slag loading;
Excavation mode: 1.2m³ bucket capacity + 4.1m excavation depth, meeting the needs of foundation construction.
Q: How to ensure reliability in extreme environments (such as deserts/extreme cold)?
A:Configure exclusive reinforcement kit:
Desert version: two-stage air pre-filter + hydraulic oil radiator (55°C high temperature continuous operation verification);
Extreme cold version: engine preheating system + low-temperature hydraulic oil circuit (-40°C Siberian oil field case).
Q: Compared with CAT/JCB equipment of the same level, what is the core advantage?
A: Three major competitive advantages:
Cost: 70% commonality of parts, 35% lower maintenance cost (compared to CAT 420);
Efficiency: 12% faster loading cycle time, 9L/h lower fuel consumption (third-party test);
Customization: 5 pre-set kits are available (such as mining version), while competitors only have 2-3 options.
