SDLG 40t-E6400F Upgraded Crawler Excavator for Harsh working conditions
E6400F is an upgraded product developed by SDLG that is suitable for a variety of harsh working conditions. This series of products adopts high-end configuration, global procurement, and careful manufacturing, which fully guarantees the high reliability and high return rate of the product.
1. Adopting the new SD130A high-efficiency diesel engine specially designed by Lingong to meet the national three emission standards, reducing emissions, improving operating performance and fuel efficiency; the engine is equipped with precise high-pressure fuel injectors, turbochargers, intercoolers and electronics The engine control system realizes the optimization of equipment performance. It is equipped with Tech Tool fault detection interface, which can facilitate the detection and maintenance of the engine; it adopts three-stage air filtration, three-stage oil filtration and three-stage fuel filtration to fully protect the engine under severe working conditions.
2. Double pump constant power negative flow automatic load-sensitive hydraulic system, automatic sensor control, with regeneration, priority and other functions, high production efficiency, strong digging ability, accurate operation and good economy.
3. The frame and durable structure can easily absorb the impact transmitted by the excavating device. The steel bar welding design between the center frame and the side frame of the upper frame, the reinforced X-shaped lower frame of the widened chassis, the lower part of the reinforcement, and the process welding design, adapt to harsh working conditions, so that the whole machine has better stability, reliability.
4. Standard reinforced HD type boom stick, refined from high-quality steel, high-strength steel is used in key parts, and special reinforcement design is carried out on stress concentration parts, which improves the working reliability under severe operating conditions; the boom stick provides Different optional types.
5. The cab is spacious, sealed, and has good sound insulation effect. It is equipped with a three-sided sunshade net; it adopts a 5-point silicone rubber shock absorber to reduce vibration and impact. Equipped with high-end damping seats and automatic air-conditioning with dual-stage air filtration, it provides a comfortable driving environment.
6. Equipped with EECU, VECU, IECU, KEYPAD and GPS electronic control system with Lingong proprietary technology, which is coordinated, energy-saving and efficient; equipped with LCD monitor, with self-checking, monitoring, emergency fault alarm, GPS positioning and remote monitoring, etc. Function, good human-computer interaction, convenient operation and maintenance. The optional rear-view camera allows the operator to see the blind area through the I-ECU monitor, thereby increasing the field of view and improving safety.
