Product Description
The LG6225E is the upgraded and updated product developed by SDXG based on the advanced technology. With high-strength chassis, enhanced reinforced implement, perfectly matched power and hydraulic systems, this product is compatible with a variety of harsh operating conditions.
The hydraulic system adopts double-pump constant power and negative flow control, which has modes of “self-sensing working mode” and “single/double-pump oil supply controllable”, and is equipped with functions of boom and arm flow regeneration and swing priority, etc., ensuring high working efficiency and good controllability of the complete machine. Hydraulic components of international brand are adopted, which ensures the reliability of the product.
The reinforced boom, arm and bucket enhances the ability of the complete excavator to adapt to harsh operating conditions; the breaking hammer,rotary grab and other implements are optionally available.
The non-slip channel and platform offers higher safety.
Applied with the X-type lower frame of the widened chassis, and the reinforced upper frame, offering higher stability and easily qualified for heavy-dutyoperating conditions.
Applied with the double-speed self-switching high-torque traveling motor, which ensures large traction; the wet brake, which offers goodsmoothness and high reliability; the optimized crawler, featuring good lubricating and sealing performance and prolonged service life.
It is equipped with supercharged inter cooling engine of second generation electric governor system EMR2, featured by strong power, economical and environmental protection and high reliability.
Applied with the large-size three-side doors and the split engine hood, which facilitate the inspection, maintenance andrepair.
Electrical system:EECU, VECU and IECU electronic control systems with SDXG patented technology are equipped, which provide various working modes for the complete machine to adapt to various working conditions and achieve energy-saving and high efficiency; color LCD monitor with functions such as self-inspection, monitor, emergency fault alarm, GPS positioning and remote monitoring is equipped, which ensures good human-machine interaction and is easy for operation and maintenance.
Wide and bright cab with open vision and good sealing performance, linkage suspension seats, two-stage filtration air condit.
LG6225E is equipped with a low noise, low emission, small size, and strong power Coummis engine. It is also equipped with a new type of independent flow distribution hydraulic system (LUDV) unrelated to the load pressure. The machine owns characteristics of energy saving, full functional, good stability, high productivity, spacious and comfortable cabin etc.
The parallel radiator cooling makes cooling effect better and maintenance easier.
