40 Ton Crawler Excavator

The engine complies with Euro V emission standards, is powerful and highly energy-efficient. The hydraulic system is designed as a variable open type and is equipped with imported high-quality hydraulic components. The big excavator responds quickly and moves precisely. 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 enhancing durability. In terms of intelligence, advanced functions such as remote control operation, intelligent weighing, and slope control can be optionally equipped. The crawler excavator is equipped with a standard quick connector, which supports the rapid replacement of various 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. In materials applications: the main frame is made of high strength alloy steel plate (yield strength 690 mpa, or higher tensile strength 790 mpa or higher); The key load-bearing parts of the working device are made of wear-resistant steel plates (with a hardness of HB400 or above). 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 Second coat treatment of electrophoretic primer for big excavators (C4 anti-corrosion grade); The key components are fastened by hydraulic tensioning bolts (with precise control of preload).

Product Advantages

Hydraulic Pilot

The innovatively designed hydraulic pilot control system is one of the core advantages of this crawler excavator. Through the carefully arranged control handles, the operator can easily achieve all functions such as equipment walking, turning, working device actions and rotating the platform. The system is highly responsive, and the control force has been optimized, significantly reducing the physical exertion of the operator. Even after working continuously for several hours, it can maintain a comfortable operation experience, truly achieving a perfect combination of efficiency and comfort.

Safe Lock

This model is equipped with a professional-level safety locking mechanism beside the cab seat. After the safety lock is activated, the control signal of the hydraulic pilot system will be completely blocked, temporarily rendering all joysticks ineffective. This protective measure fundamentally eliminates the accidental actions caused by accidentally touching the control lever during the equipment's parking period, providing a double guarantee for operational safety and significantly reducing the accident rate at the work site.

Hydraulic System

The big excavator equipped with Kawasaki's original hydraulic pump features an outstanding hydraulic system with excellent power performance and stability. The system is equipped with high-strength alloy steel hydraulic pipelines, precision hydraulic valves and high-quality sealing components, and is assembled through special processes. This advanced hydraulic system design ensures that the equipment can maintain the best working condition in various working environments, achieving efficient and precise excavation operations and helping users complete construction tasks quickly.

Engine

Crawler excavators equipped with Cummins engines have excellent fuel economy. It has been measured that fuel consumption can be reduced by about 15%, while power performance can be improved by up to 10%. This optimization significantly reduces the long-term usage cost for users. Cummins' extensive after-sales network across the country provides convenient maintenance services for the equipment. Coupled with the high reliability of the engine itself, it ensures that the equipment can continuously output strong power and maintain an efficient working state.

Hydraulic Cylinder Protection Sleeve

The cylinder protection sleeve made of high-strength composite materials has undergone a special surface treatment process and features excellent waterproof and anti-rust performance, fully adapting to various harsh working conditions. The protective cover can effectively block the flying crushed stones and sand during the construction process, preventing these impurities from causing wear and damage to the oil cylinder. This protective measure significantly reduces the wear of the oil cylinder, providing a reliable guarantee for extending the service life of the equipment.

Cab

The cab of this crawler excavator has been meticulously designed, featuring an oversized view window and ample interior space, ensuring that the driver enjoys the best operating field of vision and a comfortable experience. The wide-angle rearview mirror equipped can significantly reduce blind spots and enhance work safety. The optional sunroof design improves the air circulation inside the driver's cabin. In addition, the front window guard net, as an optional device, can reliably protect the driver from the impact of flying stones and sand on the cab, creating a safer working environment for the operator.
