Construction machinery excavator

Features

Economically fuel-efficient,with enhanced power

• Adopting electronically controlled hydraulic system, reducing fuel consumption by 7% and pursuing efficient fuel economy.
• Hydraulic main pump main valve fully electric signal control, fast action speed, improved efficiency, and maximized customer revenue.
• Equipped with a Yanmar 4tnv98I engine, it has strong power and is efficient and fuel-efficient.

Large and small arm strengthening

• The high-efficiency engine combined with the large-capacity bucket and mine-type reinforced chassis comprehensively improves production capacity.
• Structural stability and durability of the large and small arms , and i can better adapt to harsh working condition ve the wThe integrater design of the large arm bottom plate reduces the welding points of the large and small arms , anstructure to avoid stress concentratio.
• At the same time  the plate thickness of key parts is reinforced to improve.

High quality and durable

• The whole machine adopts original imported engine, main pump, main control valve travel and rotary motor, with reliable performance.
• Structural parts have been proven by the global market, can meet all-round competent working conditions and are durable.

Comfortable cab

• The design concept of “driver centered” greatly reduces the noise and vibration inside the cab; At the same time, it has an air conditioning system to meet the needs of operations in the four seasons, improving the comfort and convenience of operations.

Product Details

Big and small arms

• The large and small arm links are strengthened the plates are thick ened, and the manufacturing process is improved. The welding type is replaced by the integrated casting type.

Cab protective cover

High-strength and thickened protective glass effectively provents stons from being splashed during mining operations,making operation and driving safe and reliable.

Oil cylinder

• The hydraulic oil cylinder with strengthened design and integrated design can reduce welding seams and prevent the oil cylinder fror breaking easily.

Reliable weight bracket

• The stronger counter weight bracket design can permanently protect the core components from damage, and the thickened cover plate and super-durable fixing bolts ensure its safety and stability.

Reinforced boom cylinder support

• The stronger counterweight bracket design can permanently protect the core components from damage, and the thickened cover plate and super-durable fixing bolts ensure its safety and  stability
