YIJIANG is preparing to participate in bauma CHINA 2026 in Shanghai, where we will showcase our customized crawler undercarriage solutions and meet customers, equipment manufacturers, engineering companies, and industry professionals from around the world.
As a manufacturer specializing in custom crawler undercarriages, YIJIANG develops and supplies steel track undercarriages, rubber track undercarriages, and hydraulically extendable crawler undercarriages for a wide range of tracked machines and special equipment.
At the exhibition, visitors can learn more about YIJIANG's engineering approach to crawler undercarriage customization and discuss their specific machine requirements directly with our team.
What Custom Crawler Undercarriage Solutions Does YIJIANG Provide?
YIJIANG focuses on designing crawler undercarriages around the actual requirements of each machine rather than relying only on standard dimensions.
Depending on the application, the undercarriage can be customized according to:
• Track width and track length
• Overall undercarriage dimensions
• Load capacity
• Mounting interface
• Hydraulic travel motor integration
• Center frame design
• Ground clearance
• Rollers and front idler
• Drive sprocket
• Steel or rubber track configuration
• Hydraulic track-width extension
• Transport and working width
This allows the crawler system to be integrated with different types of upper machines and working platforms.
Steel Track Undercarriages for Heavy-Duty Equipment
YIJIANG's custom steel track undercarriages are designed for applications requiring high load capacity, durability, stability, and reliable mobility.
Typical applications include:
-
Mobile crushers
-
Aggregate conveyors
-
Drilling rigs
-
Tunnel construction equipment
-
Heavy-duty industrial machinery
-
Special tracked equipment
YIJIANG can customize the track system according to the required load above the undercarriage, machine dimensions, mounting structure, hydraulic drive, and operating environment.
The focus is not simply on producing a crawler frame, but on developing a complete undercarriage solution that can support and move the customer's specific machine.
Rubber Track Undercarriages for Low-Ground-Pressure Applications
For machines working on sensitive surfaces, uneven terrain, or applications where lower ground pressure and reduced vibration are important, YIJIANG provides custom rubber track undercarriages.
Rubber track systems can offer:
-
Lower ground pressure
-
Reduced surface damage
-
Lower vibration
-
Smoother mobility
-
Good maneuverability
-
Adaptability to compact equipment
These undercarriages can be developed for applications such as tracked dumpers, access platforms, agricultural machinery, demolition robots, firefighting robots, and other specialized machines.
YIJIANG also supplies replacement rubber tracks for different equipment and track systems. Rubber tracks are sourced from qualified suppliers according to the required specifications.
Hydraulic Extendable Crawler Undercarriages for Flexible Mobility
Some machines need a narrow configuration for transportation but require a wider stance during operation.
For these applications, YIJIANG develops hydraulically extendable crawler undercarriages.
The basic concept is:
Transport Width → Hydraulic Extension → Working Width
The crawler system can be engineered according to the customer's required transport dimensions, working width, load capacity, mounting structure, and hydraulic system.
This solution is particularly useful for equipment that needs to balance transportability, stability, and working access.
How Does YIJIANG Customize a Crawler Undercarriage?
YIJIANG follows a project-based engineering process to develop customized crawler systems.
1. Requirement Collection
Customers provide machine drawings, dimensions, load requirements, application information, or existing chassis details.
2. Engineering Analysis
Our engineering team evaluates the machine structure, load distribution, mounting requirements, track dimensions, ground clearance, drive system, and working environment.
3. 3D CAD Design
A customized crawler undercarriage is developed according to the confirmed technical requirements.
4. Drawing Confirmation
Technical drawings and key dimensions are reviewed and confirmed before production.
5. Manufacturing
After confirmation, the customized undercarriage is manufactured according to the approved design.
6. Testing and Delivery
The completed crawler system is inspected and prepared for delivery according to the project requirements.
This process allows YIJIANG to support both prototype development and batch production.
What Types of Machines Can Use a Custom Crawler Undercarriage?
A custom crawler undercarriage can be developed for many types of tracked and special-purpose machinery.
YIJIANG has experience with projects involving:
-
Tracked dumpers
-
Mobile aggregate conveyors
-
Drilling rigs
-
Tunnel trestles
-
Sugarcane harvesters
-
Firefighting robots
-
Demolition robots
-
Access platforms
-
Agricultural machinery
-
Special construction equipment
The final crawler configuration depends on the machine's dimensions, load, center of gravity, operating environment, required mobility, and mounting structure.
Real-World Custom Undercarriage Experience
YIJIANG's engineering experience comes from practical customized projects rather than only standard product production.
Previous projects have included a MOROOKA MST2200 tracked dumper rubber track undercarriage, custom rubber track undercarriages for sugarcane harvesters and firefighting robots, heavy-duty steel track undercarriages for mobile aggregate conveyors and drilling rigs, and multi-unit crawler systems for tunnel trestles.
These projects have involved different requirements for load capacity, track width, overall dimensions, hydraulic drive integration, stability, ground clearance, and operating conditions.
This project experience helps YIJIANG evaluate new crawler undercarriage requirements from both the engineering and manufacturing perspectives.
Why Discuss Your Undercarriage Project with YIJIANG at bauma CHINA?
For equipment manufacturers and engineering companies, developing a crawler undercarriage often involves more than selecting a track size.
The key questions may include:
-
What load must the undercarriage support?
-
What track width and length are required?
-
How will the undercarriage connect to the upper machine?
-
What hydraulic travel motor should be integrated?
-
How much ground clearance is needed?
-
Does the machine require steel or rubber tracks?
-
Is hydraulic track extension required?
-
What are the transport and working dimensions?
-
Can the design be manufactured as a prototype and then produced in batches?
These are exactly the types of technical questions that YIJIANG can discuss with customers during a project evaluation.
