30 Ton XE305D Cummins Engine Excavator high reliability
1. The research and development of buffer valve group and shunting
device reduces the pressure impact of the hydraulic system and
improves the control performance of the whole machine.
2. The use of high-performance silicon oil spring shock absorbers,
four-point support, effectively isolate specific frequency bands,
reduce the impact of the external environment, and improve driving
comfort.
3. Brand-new streamlined driving space design, car-level luxury
interior, wide field of vision and more comfortable.

More energy-saving and environmentally friendly
1. Cummins three-stage engine, 's proprietary power characteristic
curve, low speed and high torque, strong power and fuel economy,
can meet the construction requirements of 5000m above sea level.
2. More efficient returns
1. The Kawasaki hydraulic system imported from Japan is adopted,
and the hydraulic pipeline is upgraded to reduce the oil return
pressure loss, so that the composite operation of the front working
device is improved, the control performance of the whole machine is
improved, and the operation efficiency and coordination of the
whole machine are comprehensively improved. Sex and stability.
2. A new control system has been developed to realize the
reasonable matching of the power characteristics of the engine and
the main pump, and improve the power utilization rate and fuel
economy.
Three, more reliable and durable
1. For harsh working conditions such as heavy dust, the air intake
system is three-stage filtration, and dry or wet air pre-filters
can be selected.
2. The standard is equipped with an extended and enhanced chassis
system,
Four, more intelligent management and control
1. The advanced excavator intelligent management system adopts CAN
bus communication and Internet of Things technology, which
integrates the main control system, engine ECM, monitoring system,
control panel, GPS cloud control system and on-site diagnosis
system to realize the digital sharing of machine information and
improve Product intelligence level.
2. The autonomous controller collects the altitude of the vehicle
position and the engine intake pressure, automatically determines
the database, and prompts the operator to select the plateau mode
on the display.
Five, more comfortable and safe
