Product Description
Product Description
XGMA XG822CNG/LNG Crawler excavator adopts optimized engine output power, variable working modes, large-capacity fuel tank and reinforced structure, ensuring its top performance, high productivity and reliability.
Innovative Electro-hydraulic Control System
With a dual-pump, dual-circuit constant power control system, the engine can provide a strong operating force. Optimized operation performance of the engine reduces power loss.
Large-capacity Fuel Tank with Anti-rust Treatment
The large capacity of fuel tank reduces the frequency of refueling. The interior of the fuel tank has been well treated against rusting. No rusting will occur even if the tank is soaked in oil containing water and phosphoric acid and other chemicals for a long period of time.
Reinforced Boom and Arm
The boom and arm use large-box structure, in which welded plates against torsion form a compact, strong and durable integrity that prevents deformation under larger digging force. With optimized design, the boom and the arm can provide considerable working range and depth on ditching, excavating and other common construction situations.
Wearable Bucket
Standard reinforced bucket with highly rigid steel sheet, tips and side cutters can serve a long period.
High-strength Swing Platform
Reinforced plates, welded on the two main beam of swing platform, considerably improve the bending resistance performance.
