55 Ton Crawler Excavator

Our crawler excavator factory produces various types of crawler excavators, such as 6T, 7.5T, 15T, 23T, 30T, 37T, 40T, 50T, 55T, crawler excavators, etc.
Our crawler hydraulic excavator series has the following core advantages:
Powerful power system: Equipped with internationally renowned brand engines such as Cummins and Yangma, it has strong power, high fuel efficiency, and emissions that meet Euro V standards.
Efficient hydraulic system: Variable open hydraulic design, with imported hydraulic components to ensure rapid system response and smooth operation. Durable and sturdy structure: "H" - shaped fully rigid chassis design, high-strength steel welding, key components undergo heat treatment process to extend service life.
Intelligent control experience: Advanced functions such as remote control, intelligent weighing system, and slope control can be optionally selected to improve operational accuracy and efficiency.
Multi functional adaptability: The crawler hydraulic excavator is equipped with a quick connector, which allows for easy replacement of various attachments such as digging buckets, breaking hammers, and grab buckets, achieving multiple uses for one machine.
The main frame is made of high-strength alloy steel plate, with a yield strength of ≥ 690MPa and a tensile strength of ≥ 790MPa; Wear resistant steel plates with a hardness of HB400 or higher are used for key load-bearing parts of the working device; The surface of the forged chain rail joint of the track system is treated with induction hardening, with a hardness of HRC50-55.
Manufacturing process:
Welding process: Automated welding by robots and ultrasonic testing of welds to ensure welding quality.
Heat treatment process: The large and small arms undergo annealing heat treatment to eliminate welding stress, improve structural strength and fatigue life.
Surface treatment: The whole machine is treated with two layers of electrophoretic primer, which has strong weather resistance and a corrosion resistance level of C4 standard.
Assembly process: Key components are fastened using hydraulic tension bolt technology, with precise control of pre tightening force.

Product Advantages

Hydraulic Cylinder Protection Sleeve

The hydraulic cylinder is wrapped with a specially designed high-strength composite material protective sleeve on the outside, and its surface is treated with a professional waterproof and anti-rust coating, which can effectively resist the erosion of harsh environments such as moisture and salt and alkali. The protective cover can block the flying gravel, sand and other debris during operation, preventing them from causing direct damage to the surface of the oil cylinder. This protective design significantly reduces the wear degree of the oil cylinder, thereby effectively prolonging the overall service life of the oil cylinder.

Walking Motor

We have equipped the crawler excavator with Doosan brand traveling motors, which are renowned for their reliable quality and excellent after-sales service. These professional motors can provide strong torque and power output, enabling the equipment to easily handle heavy-duty working conditions and various complex terrain challenges. Even in extremely harsh working environments such as construction sites and mining operations, Doosan Motor can ensure the continuous and stable operation of the equipment, demonstrating outstanding performance.

Valve And Pump

Hydraulic valves and hydraulic pumps, as the core components of crawler excavators, often account for 30% or even more of the total maintenance cost of the entire machine. To ensure the stable and reliable performance of the equipment, we insist on choosing hydraulic valves and pump sets of international first-line brands. These high-quality components can not only significantly reduce energy loss and improve work efficiency, but also ensure the long-term safe and stable operation of the equipment. Meanwhile, high-quality components have significantly reduced the frequency and cost of daily maintenance, creating greater value for customers.

Hydraulic System

The core of the hydraulic system of this model adopts the hydraulic pump of the Japanese Kawasaki brand, combined with specially made alloy steel hydraulic oil pipes, high-precision control valves and imported sealing parts to form a complete hydraulic power system. All components have undergone strict screening and matching tests. The system's working pressure is stably maintained at 35MPa, ensuring that the hydraulic excavator can perform at its best under various working conditions, achieving efficient and precise construction operations, and significantly improving work efficiency and operation quality.

Engine

The Cummins engine equipped in this crawler excavator is renowned for its outstanding performance, achieving a 15% increase in fuel efficiency and a 10% boost in power, effectively controlling operating costs. Cummins' comprehensive after-sales service system ensures the timeliness of maintenance. The high reliability of the engine provides continuous and stable power output for the equipment, ensuring that the hydraulic excavator can maintain efficient operation under various working conditions and meet the long-term usage needs of users.

Hydraulic Pilot

This crawler excavator is equipped with a user-friendly hydraulic pilot control device. All operation functions, including travel control, action of the working device and rotational operation, can be easily accomplished through the control lever. The control system has been carefully tuned. The handle operation force is light and moderate, greatly reducing the physical burden on the operator. When working continuously for a long time, the operator can still maintain a comfortable operating state, which not only ensures work efficiency but also enhances work comfort.
