21 Ton Hydraulic Crawler Excavator XE215DA 1.05m3 Bucket Capacity

XE215DA adopts the latest separate pump independent control system and imported new main pump and main valve only for . With arm electronically controlled, for the same earthwork quantity, the efficiency will improve 7% and fuel consumption will reduce 10% compared with XE215D. In addition, it reduces the impacts like the start and stop of arm and boom, and greatly improve maneuverability. By adopting large-bore bucket cylinder and arm cylinder, the digging force will be increased by more than 5%.
Adopt the engine that conforms to the national III emission standard, andcustomize the low-speed and high-torque full-electronic control engine that conforms to the working condition of excavator, the torque reserve will be increased by 15%. With the full-electronic control high pressure common rail engine technology, the fuel efficiency will be improved by 5%, and it is more energy-saving and environmental riendly.
For the cracking problem of working equipment in excavator industry, the traditional way is to strengthen the structural parts, which leads to heavy weight of working equipment and high failure rate. XE215DA improves the service life ofstructural parts greatly by optimizing the hydraulic system. By way of reducing the no-load action to reduce hydraulic vibration impact, and at the same time adopting the new generation of reinforced "Caterpillar-type" bucket, the bucket capacity increases to 1.05m³, with stronger operating capacity and higher efficiency.
