Characteristics of DCC Trencher Chain

• Material

Made from high-strength alloy steel,it offers excellent wear resistance and impact resistance.This extends its lifespan,reduces replacement frequency,and lowers maintenance costs.

• Chain Structure Type

Standard chain,heavy-duty chain,multi-purpose chain.

• Chain Link Structure

The links are usually rectangular or trapezoidal in shape,with serrated edges designed to enhance cutting ability.The serrated design effectively breaks up soil and rock,improving operational efficiency.

• Connection Method

The links are connected by high-strength pins,resulting in a simple yet reliable structure.They are easy to install and disassemble,making maintenance convenient.The links are secured with bolts,providing high connection strength,making them suitable for heavy-duty chains capable of withstanding greater impact forces.

• Surface Treatment Process

Quenching and tempering:By heating and rapid cooling,the hardness and strength of the trencher chain are enhanced,followed by tempering to improve toughness.Surface hardening:Such as carburizing or nitriding,increases surface hardness while maintaining core toughness.

• Special Design Features

 Automated welding robots were used to weld the sleeves to the side panels, ensuring stability and uniformity at each weld point.

Specification Parameters

This series of transmission chain for trenchers is mainly used in dirty environment, and has high requirement on its performance in withstanding impact load. For optimized performance, we design this product based on simulated working environment. Also, we give special attentions to the design of each chain component so as to meet application demands perfectly. The design details are given below.
1. The product is designed with increased gap between the bushing and the pin, as well as the gap between the roller and the bushing. Thus, the flexible turning and rotation movements are ensured.
2. Due to the optimized clearance between the sidebar and the pin, as well as the clearance between the sidebar and the bushing, the connection firmness between the sidebars and the pin/bushing is largely enhanced.
3. The bushing with increased carburized depth helps extend the service life of the trencher chain.
4. Some wearing parts are hard chromium plated to avoid too quick surface abrasion.
 

Performance Indicators

• Service Life

Our trencher chains,which utilize automatic welding technology,high-frequency heating treatment,and corrosion-resistant surface processes,have a longer lifespan than ordinary chains,especially in environments with severe wear and harsh conditions.

• Operating Speed Range

Suitable for various operating speed ranges,it prevents chain damage or low transmission efficiency caused by speed mismatch.

• Temperature Adaptation Range

Designed for extreme environments,our trencher chains can operate across a wide temperature range,from -40°C to +300°C.

• Anti-corrosion Performance

Thanks to precise surface treatment processes,our trencher chains have excellent corrosion resistance,making them particularly suitable for environments with high humidity and strong corrosive conditions.

• Wear Resistance

Using high-frequency heating and surface reinforcement,long-term use ensures no significant wear or performance degradation.

• Noise Level

Precise welding techniques and stable structural design reduce friction and collisions between chains,thereby lowering mechanical noise and improving the working environment in factories.

Maintenance Information

• Lubrication Requirements

Although our trencher chain has good self-lubrication during operation,we recommend regular lubrication to further extend its lifespan. (It is suggested to check every 500 hours.)

• Maintenance Cycle

Our trencher chain design is simple and has a longer maintenance cycle, reducing the frequency of replacements and repairs compared to traditional chains (ensure maintenance effectiveness by using appropriate tools and lubricants).
