What Can Be Customized?
YIJIANG customizes crawler undercarriages around your machine's dimensions, load requirements, mounting interface, track system and operating conditions.
| Track Width & Length | Track width, track length and track center distance can be customized to match machine dimensions, ground pressure requirements and stability needs. Compact configurations are available for restricted spaces, while wider tracks can provide greater stability on soft or uneven ground. | Load Capacity | The undercarriage can be engineered according to the machine's operating weight, working load and weight distribution. Frame structure, rollers, track components and drive systems can be selected to meet the required load and operating conditions. |
| Mounting Interface | Mounting plates, bolt patterns, connection dimensions and other interface details can be customized to match your upper machine. YIJIANG can work from 2D drawings, 3D CAD files, PDF drawings or dimensional information. | Hydraulic Drive System | Hydraulic motors and drive configurations can be selected according to your required travel speed, hydraulic pressure and flow rate. If you already have a hydraulic circuit, provide its specifications so our engineers can evaluate compatibility. |
| Center Frame & Cross Structure | The center frame and cross structure can be customized according to the upper machine's dimensions, mounting position and load distribution. Structural dimensions and reinforcement can be adjusted for different equipment configurations and operating conditions. | Track Type | YIJIANG provides steel and rubber track configurations for different applications. Steel tracks are suitable for heavy-duty and high-load conditions, while rubber tracks can offer lower ground pressure, reduced vibration and better surface protection. |
| Ground Clearance | Ground clearance can be adjusted according to terrain, machine dimensions and obstacle clearance requirements. The crawler structure can be configured to provide the required clearance while maintaining suitable stability and overall machine dimensions. | Hydraulic Extension | Hydraulic extendable crawler undercarriages can provide a narrow transport width and a wider working stance. This configuration is suitable for equipment such as access platforms, drilling machines and special machinery operating in restricted spaces. |

FAQs
Q1: Can you customize a crawler undercarriage?
A: Yes. YIJIANG can design and manufacture custom crawler undercarriages based on your machine requirements, installation dimensions, load capacity, operating conditions, and application. We can customize track width and length, mounting interfaces, center frames, hydraulic drive systems, ground clearance, hydraulic extension, and track type. Our engineering team can also develop the undercarriage according to your machine drawings or technical specifications.
Q2: What information do you need for a custom crawler undercarriage?
A: To design a suitable crawler undercarriage, we normally need the machine weight, required load capacity, overall dimensions, track width and length, mounting interface dimensions, ground clearance, travel speed, operating environment, and hydraulic system requirements. Machine drawings, 3D models, or photos with key dimensions are also helpful. Based on this information, we can recommend the appropriate structure, track system, and drive configuration.
Q3: Can you manufacture a crawler undercarriage according to our drawings?
A: Yes. YIJIANG can manufacture crawler undercarriages according to customer-provided drawings, technical specifications, or 3D models. Our engineering team reviews the mounting dimensions, structural requirements, load conditions, hydraulic configuration, and manufacturing details before production. If necessary, we can also modify or optimize the design to improve structural strength, installation compatibility, and operating performance.
Q4: Can I order one custom crawler undercarriage?
A: Yes. YIJIANG accepts orders for one custom crawler undercarriage. Our MOQ is 1 set, making us suitable for prototype machines, special-purpose equipment, machine modifications, R&D projects and small production runs. For larger quantities, we can also provide customized OEM production and long-term supply solutions.
Q5: How long does a customized crawler undercarriage take?
A: Customized crawler undercarriages typically take 25 - 45 days to manufacture, depending on the design complexity, hydraulic configuration, component availability and order quantity. After reviewing your technical requirements, YIJIANG will confirm the estimated lead time before production.
Q6: What is the load capacity of your crawler undercarriages?
A:The load capacity of a crawler undercarriage is determined by its frame structure, track size, roller configuration, drive system, ground conditions, and operating requirements. YIJIANG designs crawler undercarriages for different equipment weights and applications, including drilling rigs, excavators, mobile crushers, access platforms, demolition robots, and special machinery. We can calculate and configure the undercarriage according to your required static and working load.
Q7: Should I choose a steel or rubber track undercarriage?
A: The choice depends mainly on the operating environment, machine weight, ground conditions, and mobility requirements. Steel track undercarriages are generally preferred for heavy-duty applications, rough terrain, high loads, and demanding working conditions. Rubber track undercarriages provide lower ground pressure, reduced surface damage, lower vibration, and better suitability for sensitive or finished surfaces. YIJIANG can recommend the appropriate track type based on your machine and application.
Q8: Do you provide technical support after delivery?
A: Yes. YIJIANG provides technical support after delivery to help customers with installation, hydraulic connections, operation, maintenance, and troubleshooting. Our technical team can provide relevant technical documents and guidance based on the supplied undercarriage configuration. For customized projects, we can also support customers with installation and application-related technical questions to help ensure reliable operation of the crawler undercarriage.
