6 Ton Crawler Excavator

As a professional crawler excavator machinery, we offer a full range of crawler excavator from 6 tons to 55 tons, including various models and specifications such as 6T, 7.5T, 15T, 23T, 30T, 37T, 40T, 50T, and 55T.
This series of heavy excavator features five core competitive advantages: Firstly, the power units are equipped with international first-line engine brands such as Cummins and Yanmar, which not only offer strong output power but also have excellent fuel economy, fully meeting the requirements of Euro V emission regulations. Secondly, the hydraulic system adopts an innovative variable open circuit design. The core hydraulic components are all imported high-quality products to ensure that the system responds sensitively and operates smoothly. Thirdly, the entire machine adopts an "H" -shaped integral chassis structure, combined with a special high-strength steel welding process. The key load-bearing components have undergone special heat treatment, significantly enhancing the service life of the equipment. Fourth, the intelligent control system supports the optional installation of advanced functional modules such as remote operation, automatic weighing, and slope control. Fifth, it is equipped with a standard quick-change mechanism, allowing for convenient replacement of various working devices and truly meeting the multi-functional operation requirements of one machine.
The main frame of this series of crawler excavator is made of high-quality high-strength alloy steel plates, with a material yield strength of ≥690MPa and a tensile strength of ≥790MPa. The important load-bearing parts of the working device are made of special wear-resistant steel, and the hardness value is maintained above HB400. The track sections of the heavy excavator track system are formed through precision forging processes, and their surfaces undergo professional induction quenching strengthening treatment, with the hardness range controlled within HRC50-55. The manufacturing process strictly adheres to the following technological standards: Welding operations are completed by a fully automatic robot system, and ultrasonic flaw detectors are used in conjunction for weld quality inspection. The main structural components such as the large and small arms, etc. all need to undergo tempering heat treatment processes to eliminate internal stress and enhance structural reliability. The surface treatment of the entire machine adopts a two-coat electrophoretic primer process to ensure that it meets the anti-corrosion standard of C4 level. The assembly of key parts adopts the hydraulic tensioning bolt technology to achieve precise control of the preload.

Product Advantages

Comfortable Seat

The seat of this DX65PC-9 crawler excavator is made of comfortable, breathable and wear-resistant materials to enhance the comfort during long working hours. In addition, the adjustability of the seat is also very important. The driver can adjust the height, forward and backward, and tilt of the seat according to their own physical needs to achieve a comfortable working posture.

Hydraulic Pipeline Of Hammer

This DX65PC-9 crawler excavator reserves the hydraulic pipeline for the breaker at the boom. This makes it convenient for customers to directly replace the breaker hammer for operation. And the hydraulic pumps, valves and pipelines are all products of well-known brands. Quality is guaranteed and it is more durable. Higher-quality sealing rings ensure that the hydraulic system can stably and continuously output greater hydraulic power.

Cab

The cab of this heavy excavator adopts a special design and technology. The cab is made of materials formed by stretching and stamping, thus achieving higher structural strength. The electrophoretic baking varnish process has better waterproof and anti-rust functions. The optional cold and heat regulator makes the working conditions comfortable.

Hydraulic System

Equipped with a hydraulic pump of the well-known brand Kawasaki. It has stable and high-intensity hydraulic output power. It is combined with high-quality hydraulic pipelines, hydraulic valves, sealing rings with excellent sealing performance and hydraulic oil pipes made of high-strength alloy steel to form a stable and powerful hydraulic system. Ensure that the excavation work is completed efficiently, quickly and with high quality during work.

Hydraulic Pilot

The forward and backward movement, turning, extension of the upper and lower arms, excavation and rotation of this crawler excavator are all controlled by a hydraulic pilot control lever. The operation is simple, convenient and efficient. And the control lever is very light, allowing for easy operation. One won't feel tired even after operating for a long time.

Safe Lock

This crawler excavator is equipped with a safety lock beside the cab seat. If in the off state, all the hydraulic pilot joysticks will not perform the action. This can ensure that no accident occurs when the vehicle is docked due to encountering the hydraulic pilot and initiating the action. This safety valve has greatly reduced the occurrence of operational accidents.
