37 Ton Crawler Excavator

Our 6T-55T full series of crawler excavator adopt an innovative structural design scheme: The whole machine adopts an "H" -shaped integral rigid chassis structure to ensure the stability of the equipment; The power system is equipped with Cummins or Yanmar brand engines, fully meeting the Euro V emission standards. The hydraulic system adopts a variable open circuit design, and the main hydraulic components are all imported high-quality products. Our crawler excavator have five core advantages: powerful performance, efficient hydraulic system, robust structural design, intelligent operation experience and multi-functional adaptability. In terms of intelligence, a variety of advanced functional modules can be optionally equipped. It is equipped with a standard quick connector, supporting the rapid replacement of various working attachments. The product line fully covers all tonnage specifications from 6T to 55T. Crawler excavator main structure with high strength alloy steel manufacturing, its yield strength is not less than 690 million mpa, tensile strength reached more than 790 million mpa. The key load-bearing areas of the working device are made of special wear-resistant steel plates, with a hardness index exceeding the HB400 grade. The track links of the crawler walking system are precisely forged and undergo surface strengthening treatment using advanced induction hardening technology. The final hardness is controlled within the range of HRC50-55. In terms of manufacturing processes: All welding procedures are fully automated by industrial robots, combined with ultrasonic non-destructive testing technology, to ensure that each weld seam meets the highest quality standards. Key structural components such as the large and small arms have all undergone professional tempering heat treatment processes, effectively eliminating welding residual stress and significantly enhancing the strength and fatigue life of the components. The surface of the large excavator has undergone two electrophoretic primer treatment processes, featuring excellent weather resistance and the anti-corrosion grade fully meeting the requirements of the C4 standard. The assembly operation of key components adopts a hydraulic tensioning bolt fastening system, which can precisely control the preload parameters.

Product Advantages

Rotary Motor

This crawler excavator is equipped with a hydraulic rotary motor of the Japanese Kawasaki brand. This motor adopts advanced hydraulic drive technology, enabling the body to rotate 360 degrees without blind spots and easily adapting to various complex construction environments. When the machine body is tilted, the operator can precisely control the rotary motor to quickly adjust the position of the machine body, ensuring that the equipment is always in the best working posture and creating favorable conditions for subsequent operations.

Valve And Pump

As key components of the hydraulic system of large excavator, the maintenance expenses of valves and pumps may account for more than 30% of the overall maintenance cost of the machine. We carefully select hydraulic valves and pumps from leading brands in the industry. These high-quality components can minimize energy loss and ensure the efficient and stable operation of the hydraulic system. At the same time, due to its outstanding durability, it significantly reduces the maintenance frequency and cost of the equipment, bringing long-term economic benefits to customers.

Comfortable Seat

In the design of the DX370PC-9 large excavator, the comfort of the seat is a key consideration factor. It adopts high-quality breathable and wear-resistant fabric, combined with ergonomic design, which greatly enhances the comfort of long-term work. The seat supports multi-directional adjustment function, allowing the driver to easily adjust the seat height, forward and backward position, and backrest Angle, ensuring that operators of different body types can achieve the best working posture and significantly reducing work fatigue.

Hydraulic Pilot

This large excavator is equipped with a precise hydraulic pilot control system, and all action instructions can be completed by operating just a few control levers. This includes the control of the overall walking direction of the machine, various actions of the working device, and the rotational movement of the upper body, all of which can be precisely accomplished through this intuitive control system. The control lever's force adjustment is just right, making the operation light and effortless. It significantly reduces the labor intensity of the operator and ensures the comfort and efficiency of long-term work.

Walking Motor

It adopts the original imported traveling motor of Doosan, which not only ensures the quality but also makes the after-sales service network more complete. These professional-grade motors feature outstanding power output characteristics, providing sufficient torque and power for large excavators, enabling them to handle heavy loads and complex terrains with ease. It is particularly suitable for harsh working environments such as construction sites and mineral mining, demonstrating outstanding adaptability and reliability.

Track

The track is the core supporting component of the overall body of an large excavator. The use of high-strength alloy steel material can cope with various complex terrains for operation. And more reinforcing ribs have been added to the tracks to ensure the strength of driving and support. It can ensure the stable and continuous operation of the walking system during operation.
