SDLG Excavator E6215H

High-strength chassis, robust structural components, stable operation
• Configured with Lingong’s classic and mature 22T platform chassis, providing excellent operational stability, durability, wear resistance, and impact resistance for a long service life;
• Reinforced work device and frame, robotically welded, inspected with weld flaw detectors, and shot blasted to reduce stress and ensure high reliability;
• Customized structural component plates, manufactured using globally advanced processes, offering high load-bearing capacity and long service life.

Fully electronic hydraulic system, fuel-efficient and highly efficient
• Utilizes Lingong’s independently developed electronic control system, with finely optimized electro-hydraulic control system; the main valve integrates proportional solenoid valves for full electrical control, replacing pilot lines with wiring connections, resulting in a simpler oil circuit and lower pressure loss;
• Independent control of each machine movement, intelligent flow merging, quick response, high flow distribution efficiency, and fuel efficiency;
• Optimized main valve and handle control curves improve controllability for various precise operations such as loading and leveling;
• Large displacement main pump provides ample flow, resulting in faster movements and higher efficiency;
• Uses a large displacement swing motor for stronger torque.

Roll-Over Protective Structure (ROPS) Cab, Intelligent Control
• The cab features a simple and stylish design, and comes standard with a roll-over protective structure, ensuring safer and more reliable operation in the field; the enlarged interior space provides better visibility and a more comfortable ride;
• Equipped with an 8-inch LCD color display, which is clear and easy to read, providing a clear view of the machine’s operating status;
• The right-side control box integrates multiple switches for page turning, throttle level, high/low speed travel, and maximum power mode, all within easy reach for convenient operation;
• The new generation air conditioning system features a large air volume and excellent cooling performance; the raised front air vents provide a more reasonable and comfortable airflow;
• The large PC sunroof offers a wider field of vision, better lighting and ventilation; front, top, and rear sunshades, and a right-side curtain provide enhanced comfort and user-friendliness.

Convenient Maintenance, Centralized Service Points
• The left and right engine hoods and the top engine hood have a large opening angle for convenient maintenance;
• The left hood houses the E-ECU, machine fuses, relays, and engine air filter; the right hood houses the fuel filter, oil filter, and main pump pressure test port;
• The top engine hood houses the intake preheating, intercooler, and auxiliary water tank, facilitating maintenance;
• The enlarged radiator ensures low hydraulic oil temperature, easily handling river conditions, and enabling more efficient demolition and hammering operations.
