23 Ton Crawler Excavator

The full range of crawler excavators from 6 tons to 55 tons features the following outstanding performance characteristics: The power system is equipped with Cummins or Yanmar brand engines, fully meeting the Euro V emission standards, with strong power output and excellent fuel efficiency; The hydraulic system adopts a variable open circuit design and is equipped with imported high-quality hydraulic components to ensure rapid response and smooth operation of the system. The large excavator adopts an "H" -shaped integral rigid chassis structure as a whole, combined with high-strength steel welding technology. The key components have undergone heat treatment, significantly enhancing the structural strength and service life. In terms of intelligence, advanced functions such as remote control operation, intelligent weighing, and slope control can be optionally equipped. It is equipped with a quick connector, allowing for convenient replacement of various working attachments such as buckets, breakers and grabs. The product line comprehensively covers various tonnage specifications such as 6T, 7.5T, 15T, 23T, 30T, 37T, 40T, 50T, and 55T. According to strict manufacturing standards: crawler excavator main frame is made of high strength alloy steel plate (yield strength 690 mpa, or higher tensile strength of 790 mpa or higher); Wear-resistant steel plates (with a hardness of HB400 or above) are used for the key parts of the working device. The track chain link is forged and then subjected to induction hardening treatment (hardness HRC50-55). The manufacturing process includes: robot automated welding (ultrasonic flaw detection); Tempering heat treatment of the upper and lower arms The whole machine undergoes two coats of electrophoretic primer treatment (C4 anti-corrosion grade); Hydraulic tension bolt fastening of key components (precise control of preload).

Product Advantages

Engine

This large excavator is equipped with an engine of the well-known brand Cummins. This engine can improve fuel efficiency, reduce fuel consumption by about 15%, and increase power by 10%. It has significantly reduced the long-term usage cost. Moreover, the after-sales network is well-developed, maintenance is convenient and reliability is strong. Meanwhile, this engine can provide powerful and stable power to ensure the continuous and efficient operation of the crawler excavator.

Hydraulic System

This crawler excavator is equipped with an original imported hydraulic pump from Kawasaki, Japan, providing continuous and stable high-pressure hydraulic power output. The system adopts high-quality alloy steel hydraulic pipelines, combined with precise hydraulic control valve groups and high-performance sealing components, to form a highly efficient and reliable hydraulic transmission system. All components have been precisely matched and strictly tested to ensure excellent working performance under various working conditions, making excavation operations more efficient and smooth, and significantly improving construction quality and operational efficiency.

Hydraulic Pilot

This large excavator adopts an advanced hydraulic pilot control system, and the all-round operation of the entire machine can be completed through the carefully designed control lever. Whether it is forward and backward movement, left and right turning, or the precise extension of the large and small arms, excavation operations and platform rotation, all can be easily achieved through this system. The control lever is designed in accordance with ergonomic principles, with a light operation force. Even after long-term continuous operation, it will not cause fatigue, greatly improving work efficiency and operational comfort.

Walking Motor

We choose the traveling motor of the Doosan brand from South Korea. This brand enjoys a high reputation in the field of construction machinery, and both the product quality and after-sales service are reliably guaranteed. These high-performance motors can output strong torque and power, ensuring that crawler excavators can easily handle heavy-duty operations and various complex terrain challenges. Even in extreme working conditions such as construction sites and mining operations, Doosan motors can maintain stable and reliable operation performance, providing long-lasting power support for equipment.

Radiator

The engine radiator of this large excavator adopts water-cooled heat dissipation. The structure with large grids and extended pipelines can carry out heat dissipation work better and faster. And it is convenient for maintenance. It can provide continuous and stable working guarantee for the engine.

Hydraulic Cylinder Protection Sleeve

The specially developed high-strength composite material protective sleeve is tightly wrapped around the outside of the hydraulic cylinder. Its special coating treatment endows the product with excellent waterproof and anti-rust properties, and it can withstand harsh environments such as dampness and saline-alkali. The protective cover can effectively isolate the sand, stones and other impurities that splash during operation, preventing these substances from causing direct damage to the oil cylinder. This innovative design significantly reduces the wear rate of the cylinder, thereby effectively prolonging the service life of the cylinder.
