XCG Entelctrl remote intelligent service system

1. Supervise machine operation parameters in real time, knowing operating status of the equipment at a glance;

2. Remote diagnosis and failure pre-warning;

3. Automatic remind of scheduled maintenance;

4. GPS machine position allocation.

Computer power control

H__the engine throttle is at the max fuel supply position, the pump is set at the Max load output. Under this condition, the engine runs at the maxim speed, full power and the shortest working circle.

S__suitable for normal excavation and loading operation, short circle time, low fuel consumption, high working efficiency.

L__the engine is set at relatively lower speed, suitable for leveling after excavating work.

Power system

The original Cummins B5.9-C engine with unique design, it has 40% less parts and components comparing with other similar engine of this category so the failure rate greatly reduced. The daily maintenance is easy because no need of any special tools.

The engine is lighter, Euro II emission meets the environmental protection requirements, and yet powerful.

The unique radiation system enable an uniform cooling distribution. Even in hot summer condition it can maintain normal engine working temperature.

It adopts the direct-fuel-injection system, forced lubricating with full-flow oil filtration and the multistage dry air filter.

The automatic dust discharge valve and air filter jam indicator, make maintenance simpler and extend air filter service time.

Reliable hydraulic system

Main valve:

The newly incorporated inner-mounted fully automatic interlock system (comparing with original Series 7) increase the operation safety greatly.

Inner-mounted special oil inlet safety valve- overload protection and anti-cavity;

The fast response negative flow system guarantee it is in low flow when control level at neutral position to minimize power consumption.

The unique design of the new spool greatly increase the operation preciseness; The incorporated jet-flow sensor in the valve, swing priority, arm priority, boom priority, including the unique bucket flow combifunction- realize the interflow on every side (swing arm, bucket rod, bucket), straight travel;

Return oil regeneration- energy saving;

Adjustable stand-by valve- it can be fitted with various hydraulic machinery and tools, expand the excavator operation function;

Hydraulic pump:

The negative flow, dual-pump crossed full-power control system, has unique energy saving, rapid response;

KR3 series regulator- the flow reset automatically, start without load, effectively prevent the overload. The low flow instruction has the priority in control, the energy saving is prior;

The new oil way design, the integration of the pump is higher and the operation is more reliable.

Swing mechanism:

Wear-free hydraulic brake, mechanical delay lock- extend the lifetime.

Inner-mounted buffer starting valve set, pressure adjusting valve- smooth and no impact.

Inner-mounted main and secondary dual hydraulic anti-reverse valve- rapid, accurate swing positioning control, the working stability further improved.

The oil level gauge also has the function of air moisture absorption- fit in with the violent temperature change between day and night to resist damp air.

The integrated design of motor, planetary reduction- more compact structure and more convenient maintenance;

The hydraulic oil tank has unique metal magnetic rod for abstracting metal particles and maintain the cleanness of hydraulic oil.

The standard oil filling pump- provide maxim user convenience.
