YIJIANG designed and manufactured two custom triangular rubber track undercarriages for a 5.5-ton sugarcane harvester used in Fiji. The crawler system was developed to provide stable mobility on soft and uneven agricultural terrain while maintaining suitable ground clearance and traction. The undercarriages use rubber tracks, hydraulic drive and a custom mounting interface to integrate with the customer's sugarcane harvesting machine.

Why Was a Triangular Rubber Track Undercarriage Used?
Sugarcane harvesting machines operate in fields where soil conditions can vary significantly. Soft soil, uneven ground and crop residue can make wheeled mobility more difficult.
The triangular rubber track configuration provides a longer track contact area and a raised front section, helping the harvester maintain stability and ground clearance when travelling across uneven agricultural terrain.
Rubber tracks also provide a larger contact area than conventional wheels, helping distribute the machine load over the soil.
How Was the Undercarriage Customized for the Sugarcane Harvester?
Triangular Track Frame
The undercarriage uses a triangular frame configuration developed around the dimensional and mobility requirements of the sugarcane harvester. The frame geometry provides the required track layout while maintaining suitable ground clearance.
Rubber Track Configuration
Rubber tracks were selected for the agricultural application to provide a large contact area and suitable traction on field surfaces. Track dimensions were customized according to the machine's load and installation requirements.
Hydraulic Drive
The crawler undercarriage uses hydraulic drive to provide powered movement of the harvester. The hydraulic drive configuration was integrated according to the machine's available hydraulic system and mounting requirements.
Custom Mounting Interface
The mounting interface was customized to connect the two crawler undercarriages with the existing sugarcane harvester structure. This allows the crawler system to be integrated into the customer's machine without redesigning the complete harvesting machine.
How Do Two Triangular Track Undercarriages Support the Harvester?
The sugarcane harvester uses two triangular rubber track undercarriages as its left and right travel units. Each crawler supports one side of the machine and transfers the machine load to the ground through its rubber track.
The two undercarriages work together as the machine's mobile foundation, providing powered tracked movement while maintaining the required machine width, ground clearance and stability.
Executive Summary
Client: South Korean Firefighting & Rescue Equipment Manufacturer
Application: Remote-Controlled Firefighting & Rescue Robots
Solution: Customized Triangular Rubber Track Undercarriage by Yijiang Machinery
Key Benefits: High ground clearance, exceptional obstacle-crossing capability, and enhanced operator safety.
The Challenge: Navigating Hazardous and Complex Terrains
Firefighting and rescue missions present some of the most treacherous environments for personnel and machinery. A leading firefighting equipment manufacturer in South Korea needed a mobility solution for their next-generation remote-controlled firefighting robot.
The robot required a high-stability mobile platform capable of carrying heavy payloads—such as high-pressure water cannons and industrial cooling fans—through debris-strewn, uneven, and hazardous terrains. Standard wheeled or flat-tracked platforms lacked the necessary ground clearance and traction to navigate stairs, slopes, and unpredictable collapse zones safely.
The Solution: Customized Triangular Rubber Track Undercarriage
To meet these rigorous demands, Yijiang Machinery engineered a customized Triangular Rubber Track Undercarriage specifically tailored for firefighting robots.
| Item | Specification |

| Customer | South Korean Firefighting Equipment Manufacturer |
| Undercarriage Type | Custom Triangular Rubber Track Undercarriage |
| Track Width | 320 mm |
| Undercarriage Length | 2170 mm |
| Load Capacity | 4 tons |
| Undercarriage Weight | 1.6 Tons |
| Travel Speed | 2–4 km/h |
| Gradeability | 30° |
| Track Type | Heat-Resistant Rubber Track |

Key Engineering Highlights:
Triangular Geometry Design: The elevated drive sprocket design significantly increases ground clearance, allowing the robot to easily climb over obstacles, debris, and steep inclines without high-centering.
Premium Rubber Tracks: Built with high-strength, heat-resistant rubber tracks reinforced with steel cords, ensuring excellent traction on slippery surfaces, mud, and rubble without damaging urban pavement.
Robust Structural Integrity: Utilizing expert manual welding and strict quality verification, the chassis delivers maximum structural durability under extreme heat and heavy loads.
Flexible Integration Interface: The top frame was custom-designed to seamlessly integrate with the client’s specialized fire-suppression systems, including high-capacity water cannons and smoke extraction fans.
The Results: Safer, Smarter Firefighting Deployments
The integration of Yijiang’s customized triangular chassis completely transformed the capability of the client's firefighting robot.
Enhanced Mission Safety: By deploying the remote-controlled robot into the heart of the fire zone, firefighting and rescue teams can now execute critical missions from a safe distance, drastically reducing human exposure to toxic smoke, explosions, and structural collapses.
Versatile Payload Delivery: The stable and rugged chassis allows the robot to steadily operate its water cannons for active firefighting or industrial fans for rapid smoke ventilation in complex environments like warehouses, tunnels, and chemical plants.
Client Satisfaction: The South Korean client highly praised Yijiang’s precise customization capabilities, robust craftsmanship, and reliable delivery, establishing a solid foundation for future partnership in smart rescue solutions.
