Mountain heavy MC56-9 hydraulic excavator (fourth) - high reliability

MC56-9 excavator adheres to the design principle of high reliability, selects excellent parts, optimizes and strengthens the whole machine parts, so that the reliability of the whole machine can be greatly improved.

1, sturdy upper and lower frame

(1) The upper and lower frames adopt structural stress analysis technology to achieve a reasonable high-strength structure;

(2) The upper frame adopts modal analysis technology, which is sturdy and durable, effectively reducing machine vibration and reducing noise;

(3) The track frame adopts X type, which has high strength and strong bearing capacity;

(4) Robot welding process, flaw detection and quality assurance.

2, reliable walking device

(1) The Group cooperates with the four rounds, quality assurance, reliable and durable;

(2) The sprocket wheel and the roller are universal, the market service is more convenient and the reliability is higher;

(3) The carrier roller adopts the support structure at both ends, and the bearing capacity is stronger;

(4) The track link section width is increased and the reliability is improved (27mm-30mm);

(5) Standard reinforced blade, durable, durable and reliable.

3. Optimized and enhanced working device

(1) Through the CAE technology, simulate the maximum working condition of the boom stick, analyze the structure of the stress concentration area, and further optimize the structure to ensure its high reliability;

(2) The bucket side plate and the main blade are reinforced, the shape is optimized, the bottom of the bucket is not grinded, the measuring blade tooth is common with the D-type vehicle, and the market is verified;

(3) Optimized and strengthened the boom structure, the side plate thickness is increased to 8mm, the section is enlarged, and the strength is strengthened;

(4) The main body of the stick is U-shaped steel structure with few welds and good workmanship. The thickness of the stick is increased to 8mm and the strength is high.

4, beautiful and durable appearance

(1) All-metal sheet metal front and rear hoods and side doors made of full-mold, beautiful and rigid;

(2) All sheet metal parts are subjected to electrophoresis treatment and weather-resistant paint, which has good spraying effect and strong weather resistance.

(5) Remaining reliability improvement

(1) Adopt stable and reliable power and hydraulic system configuration, low failure rate and good market performance;

(2) Improve the stability of the electrical system by using well-known brand electrical components, such as HELLA lamps, horns, and Daojia wipers;

(3) The air-conditioning system adopts the structure of direct-loading compressor, which has high reliability and convenient tension adjustment;

(4) Optimize the hydraulic line of the whole machine, and at the same time, the boom hose is built in, which can effectively avoid the wear of the hose during deep drilling and turning operation;

(5) Adopting a parallel heat sink, the effect is good, the maintenance and cleaning is convenient, and the heat dissipation system has high reliability;

(6) Accessories such as hood locks are selected from proven market structures and are reliable and durable. (This article comes from the mountain reconstruction machine)
