Bucket teeth are crucial components of an excavator and are also the most vulnerable to wear. They consist of a tooth base and a replaceable tip, connected by a pin. Since only the tip wears out, replacing it is sufficient, making the quality of the bucket teeth critical for cost-effectiveness.

Introduction
Excavator bucket teeth play a crucial role in the efficiency, durability, and productivity of excavation work. Choosing the right type of teeth and understanding their material characteristics can significantly impact the performance and longevity of your machine. In this guide, we'll explore the different materials used in bucket teeth, how to maintain them, and how to choose the right type based on your working conditions.
Excavator buckets are categorized based on their working methods into backhoe buckets and front shovel buckets, with the backhoe bucket being the most commonly used.
The Caterpillar 3406 engine, known for its high performance and widespread application in various heavy machinery and construction equipment, is recognized in the industry for its reliability and durability. However, even such an excellent engine can encounter some common maintenance issues during everyday use, one of which is the replacement of the crankshaft rear oil seal. This article will provide a detailed overview of the crankshaft rear oil seal of the Caterpillar 3406 engine, including its importance, material selection, replacement steps, and preventive measures, offering practical reference for mechanics and owners.
The forging tooth forming hydraulic press is the core machine in the forging tooth production process. By applying external force to the metal raw materials using this press, it causes plastic deformation of the metal, changing the shape and size of the billet while improving its internal structure and mechanical properties, resulting in the final formed forging tooth. Forging eliminates defects such as porosity generated during the metal smelting process, optimizes the microstructure, and since it preserves the complete metal flow line, the mechanical properties of forgings are generally superior to castings made from the same material. Therefore, although the forging tooth production process is costlier, it ensures the highest quality for the forged teeth. The forging tooth is a crucial component on excavators, similar to human teeth, and is an easily worn part, requiring continuous production and processing to meet demand.
The earthwork bucket, the most familiar type of bucket in daily operations, is almost a standard configuration for small and medium-sized excavators. This type of bucket typically uses standard thickness plates, and its design lacks significant reinforcement measures on the bucket body.
Excavator buckets come in various types and serve different functions. In daily operations, we often see buckets of different shapes and sizes, each carefully chosen according to specific working conditions. Let’s explore several common types of buckets and examine their unique functions and applicable scenarios.
A track is a flexible chain loop driven by the drive wheel, operating around the drive wheel, idler wheel, tensioning wheel, and support rollers. This chain loop consists of key components such as the track plate and track pin. The track pin connects the individual track plates, forming a complete track loop.
Tracks, as a unique method of mobility, are widely used in fields such as construction machinery, agricultural machinery, and military equipment. Compared to traditional wheel hub drive systems, tracks offer distinct advantages and are suitable for specific applications.
Mr. Zhang from Chaozhou, Guangdong Province, already owns four CAT® (Caterpillar) excavators, but he’s far from satisfied with his current fleet. He's aiming for further expansion—buying more equipment and taking on even more projects.
Amid the global shift toward greener and smarter construction machinery, Shandong Lingong (SDLG) continues to drive development through innovation. The ER6155H medium-sized excavator stands as a prime example of SDLG’s innovative capabilities. Combining intelligence, efficiency, safety, and environmental performance, the ER6155H builds on SDLG’s legacy of reliability. With powerful performance and intelligent technology, it sets a new benchmark for innovation in medium-sized equipment and marks the beginning of a new era in intelligent construction.
When you think of excavators, you probably imagine the powerful "steel giants" on construction sites. However, in many specialized scenarios—such as interior renovations, landscaping, or working in narrow alleys—the agile "small wonders" are the true efficiency champions.
Today, let's talk about the "small yet refined" members of the giant family of Hitachi Construction Machinery, especially the smallest models of excavators.
The launch ceremony, themed "Official Certification, Revitalizing New Life," marks a significant breakthrough in XCMG's global layout of the remanufacturing industry. It also injects strong momentum into the sustainable development of the global construction machinery industry through innovative practices.
"In Europe, for Europe, XCMG is committed to becoming an important participant and trusted partner in Europe's low-carbon, intelligent, and sustainable development." At the opening ceremony, Yang Dongsheng, Chairman of XCMG Group and XCMG Machinery, stated, "The German-Chinese saying, 'The fast walk alone, the far walk together' is a fusion of wisdom from both nations." He emphasized, "We always adhere to our mission of 'Engineering technology leads, equipment builds a better future' and our sustainable development strategy of 'globalization.' We are determined to create more value for customers and contribute to global sustainable development."
On April 7th, local time, the bauma 2025 exhibition kicked off at the New International Expo Center in Munich, Germany. At 10:28 AM, Mr. Zhan Chunxin, Chairman and CEO of Zoomlion, along with the executive team, launched the company’s theme exhibition titled “Green · Intelligent Manufacturing, Building a Beautiful World Together.” On the day of the event, new product releases from various sectors of the company continued, with intensive product sales and strategic cooperation agreements being signed, and global customers engaging in continuous discussions. At this prestigious industry exchange event where top global brands gathered, Zoomlion’s expanding global customer base not only showcased the results of the company’s global development but also highlighted the role of Chinese equipment manufacturing companies, represented by Zoomlion, in leading the trends of digital, intelligent, and green development in the industry.
Purchasing a used excavator is a process that involves multiple considerations. Below are detailed steps and important factors to keep in mind:
Many friends have asked me a question: What is the price difference between SANY excavators and CAT in the U.S. market?
I dropped out of high school in my first year. It was a private school in my hometown, and those who know, know—the learning environment was terrible. Instead of staying, I decided to help ease my family's financial burden. My family suggested I learn to operate an excavator, so I went for it. I went to the site with my father, who works as a formwork carpenter—a tough job. My brother found me a mentor… but I had to wait nearly a month and a half. During that time, I was frustrated and bored.
What I’m about to discuss is something industry insiders should already be aware of. Perhaps you know everything I’m going to say, or maybe just parts of it.
The primary function of the engine lubrication system is to prevent friction between parts that have relative motion.
Excavators are relatively cheap in the Chinese market, mainly due to China’s accumulation of a large number of excavators over the past 40 years. The used excavator market is very active, and the performance of used excavators is not significantly different from new ones.
Chinese and Non-Chinese excavators each have their own strengths and weaknesses, catering to different market demands and usage environments. Below is a comparison of the two:
The used excavator market in China has been developing rapidly in recent years. As demand for machinery in industries such as construction, mining, and transportation continues to grow, used excavators have become an important choice for many companies to save costs and improve work efficiency.
