49 Ton XE490DK Hydraulic Crawler Excavator Heavy Duty
Performance advantages:
’s proprietary low-speed and high-torque engine, coupled with a large-displacement main pump, has a faster response speed, ensuring efficient operation and better fuel economy;
dedicated "full independent cooling technology" and high-power radiator, low fan energy consumption, suitable for high temperature environment of 50°C
Set N/P/T/B four operating modes for different working conditions
XE490DK adopts "load adaptive control technology", which can adjust the absorption power of the main pump in real time according to load changes to ensure that the engine always runs in the fuel consumption economic zone;
Adopt dedicated "self-optimizing control technology based on crushing conditions" to intelligently match the best engine speed and main pump power to reduce fuel consumption under the same crushing efficiency
More than 20%, more energy-saving and efficient;
One-key matching control of single pump/double pump combined flow, equipped with drain filter and broken filter
It adopts heavy-duty H-type short boom and short forearm, reinforced connecting rod and rocker, anti-collision beam, original car breaker pipeline, full guard rail clamp, etc., which is more suitable for the harsh working conditions of the mine;
Heavy-duty chain rails for mines, with a pitch of 226mm and a pin diameter of 47.2mm; strong and durable;
Heavy-duty double-tooth track shoes, thicker and higher grousers, good gripping ability, strong ability to pass impact, and more reliable mining operations.
