Project Description
SDLG
Engine: SDLG SD6B Engine
Operating weight: 21700kg
Bucket Capacity: 1.2 CBM
E6225F is a core product jointly developed by SDLG and Volvo experts after fully investigating the Chinese market. The product has high-strengthened chassis, heavy working device, optimized matching power hydraulic system, suitable for a variety of harsh conditions.
● The original imported low-speed and high torque D6 engine with supercharging and intercooling, can meet T3 emission. Strong power, economic and environmental protection, are more suitable for mine operation. It adopts three-stage air filtration, three-stage oil filtration and three-stage fuel filtration, with high reliability.
● Double pump constant power positive flow hydraulic system, automatic sensing control, with regeneration, priority and other functions.
● The reinforced lower frame with lengthened crawler and widened chassis has good trafficability and higher operation stability of the whole machine.
● Equipped with EECU, VECU, IECU, keypad and GPS electronic control system with special technology. It has functions of self-inspection, monitoring, emergency alarm, GPS positioning and remote monitoring, with good man-machine interaction and convenient operation and maintenance.
● The cab is spacious and has good sound insulation effect. It is equipped with three sunshade nets. Silicone oil rubber shock absorber is used to reduce vibration and impact.
● It can be equipped with various working devices and accessories such as crushing hammer.
