21ton Cummins Eninge Kawasaki Pump Excavtor
1,Introduction:
Cummins engine (conforming to Ⅱ-stage emission regulations),
powerful, energy efficient, reliable and durable; advanced negative
flow hydraulic system, comfortable operation, high operating
efficiency, excellent cost performance; full power control, four
power modes to adapt to different work; reliable and accurate fuel
injection system, real-time control of fuel injection, making
combustion more complete, fuel efficiency; full 3D modeling and
finite element analysis technology to ensure the reliability and
stability of structural parts.
2. Characteristics:
Cummins new generation high-power engine with strong power, low
fuel consumption and high reliability
New hydraulic system, large displacement main pump, large flow main
valve, large flow area, small pressure loss, more reasonable flow
distribution, better coordination and easier operation
Equipped with a large-bore oil cylinder, optimizing the arrangement
of key hinge points, improving the digging force of the whole
machine, setting an automatic supercharging function, and
automatically increasing the digging force as the load increases;
large displacement slewing motor and slewing gear design with large
speed ratio Higher starting torque, better slewing braking effect.
Aiming at the extremely harsh mining operation conditions, the
heavy-duty reinforced boom, the mine-specific short stick and the
large-capacity rock bucket are standard, and the extended and
widened heavy-duty chassis is standard.
Equipped with high-resolution, high-brightness 5.7-inch color
anti-glare monitoring instrument, intelligent electronic monitoring
system, with vehicle maintenance information prompts, fault
self-diagnosis and alarm and other functions;
