50 Ton Crawler Excavator

We offer a full range of crawler excavator equipment solutions from 6 tons to 55 tons, and our crawler excavator product line comprehensively covers all tonnage requirements. This series of products features five core advantages: equipped with engines from internationally renowned brands such as Cummins and Yanmar, it complies with Euro V emission standards, offering strong power and high energy efficiency. The hydraulic system is designed as a variable open type. The main hydraulic components adopt imported brands to ensure rapid system response. The whole machine adopts an "H" -shaped fully rigid chassis structure, combined with high-strength steel welding technology. Key components have undergone heat treatment, significantly extending the service life. In terms of intelligence, advanced functions such as remote control operation, intelligent weighing, and slope control can be optionally equipped. The large excavator is equipped with a quick connector, which supports the rapid replacement of various working attachments. The specific models include various tonnage specifications such as 6T, 7.5T, 15T, 23T, 30T, 37T, 40T, 50T, 55T, etc.
Technical parameters: crawler excavator main frame is made of high strength alloy steel plate (yield strength 690 mpa, or higher tensile strength 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 subjected to induction hardening treatment after forging (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

Safe Lock

The innovatively designed safety lock beside the seat is an important safety feature of this large excavator. In the locked state, the system will automatically cut off the hydraulic pilot control circuit, rendering all operation instructions of the joystick invalid. This intelligent protection mechanism effectively prevents unexpected actions of the working device caused by misoperation when the equipment is parked, eliminating potential safety hazards at the source and significantly enhancing the safety performance of the equipment.

Radiator

This crawler excavator is equipped with an advanced water-cooled engine cooling system. It adopts a large-sized cooling grid design combined with an extended circulation pipeline structure, significantly enhancing the cooling efficiency. This optimized design can quickly and effectively reduce the engine temperature, and at the same time facilitate daily maintenance and care, providing a reliable guarantee for the continuous and stable operation of the engine and ensuring that the equipment can maintain the best working condition under various working conditions.

Walking Motor

The choice of Doosan brand walking motors is based on its outstanding product quality and perfect after-sales service system. These high-performance motors can continuously output strong power, ensuring that the big excavator maintains excellent performance even under heavy load operations and complex terrain conditions. Whether it is high-intensity construction or harsh mining environments, Doosan motors can work stably and reliably, providing long-lasting power support for equipment.

Valve And Pump

In the operating cost structure of crawler excavators, the maintenance costs of valves and pumps account for a considerable proportion, usually exceeding 30% of the overall maintenance cost of the machine. For this reason, we specially adopt hydraulic valves and pump sets produced by top manufacturers. These high-performance components not only have higher working efficiency and less energy loss, but also operate more safely and reliably. More importantly, high-quality components have a longer service life, thereby effectively reducing the overall maintenance cost of the equipment.

Cab

This crawler excavator features a panoramic cab design, offering a wide field of vision and spacious operating space, significantly enhancing driving safety and operational comfort. Equipped with a wide-angle rearview mirror system, it effectively expands the visible range and reduces the blind spot during operation by up to 40%. The cab can be optionally equipped with a top skylight to enhance air circulation and keep the indoor air fresh. In particular, a high-strength protective net can be installed in the front window area to effectively block the impact of flying stones and sand on the car window, providing comprehensive safety protection for the driver.

Comfortable Seat

The DX500PC-9 large excavator is equipped with a elaborately designed driver's seat, made of high-quality materials with high breathability and wear resistance, providing the driver with a lasting comfortable experience. The seat is equipped with multiple functions such as height adjustment, forward and backward sliding, and backrest Angle adjustment, allowing the operator to make personalized Settings according to their personal needs and find the most suitable driving posture for themselves, thus maintaining a comfortable state during long working hours.
