Wear Free Hydraulic Brake Mechanical Excavator Machines 1.1m3 Rated Bucket Capacity

23 ton 1.1 CBM Bucket Hydraulic Crawler Excavator With Cummins Engine With John Deer Technology

Engine

※ The original Cummins 6BTA5.9-C engine with unique design, it has 40% less parts and components comparing with other similar engine of the same kind so the failure possibility 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 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.

Hydraulic Component: Comprehensive Promotion

Main Pumps:

※ 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.

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 comb function- 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 machines and tools,expand the excavator operation function;

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.

Travel Mechanism:

※ Intelligent dual speed switchover- automatically sense the gradient resistance and adjust the speed;

※ Inner-mounted buffer starting valve set- smooth start and no impact; inner-mounted automatic changing-over slide valve- for immediate stop while traveling;

※ New closed wet disc brake device- increased slope packing safety.
