Case Study: Custom-Manufactured Large Track Frames For Heavy Excavator

The excavation industry is constantly evolving, and so is the demand for heavy-duty machinery that can handle the toughest jobs. One of the most critical components of a heavy excavator is the track frame, which provides the necessary support and stability for the machine to operate effectively in challenging environments.

Recently, our company was approached by a customer in Africa who required custom-made large steel welded components - track frames for heavy excavators. The customer provided us with detailed drawings and specifications, and our team of skilled technicians went to work on the project.

The Manufacturing Process

The manufacturing process for the track frames involved several key steps, including custom-made steel plates, cutting, welding and assembly, machining (turning, milling, drilling), painting, inspection, and more.

  • Cutting and Forming: Firstly, custom-made steel plates were used to form the individual components of the track frames. The steel plates were carefully cut and shaped according to the customer's drawings to ensure that they met the required specifications.
  • Welding and Assembly: The next step was welding and assembly. Our skilled technicians used advanced welding techniques to join the individual components together into a single, large track frame. The welding was performed with utmost care and precision to ensure the structural integrity and durability of the frames.
  • Machining: Once the welding was complete, the track frames were then machined using specialized turning, milling, and drilling equipment. This process involved precise cutting and shaping of the components to ensure that they fit together perfectly and met the required tolerances.
  • Inspection and Painting: After the machining was complete, the track frames underwent a thorough inspection to ensure that all dimensions and tolerances were within the required specifications. Once the inspection was complete, the frames were painted to provide additional protection against corrosion and wear.

The track frames were shipped to Africa successfully, and our customer was extremely satisfied with the quality and reliability of the product. The frames were installed on heavy excavators, and they have been operating effectively in the toughest conditions, providing the necessary support and stability for the machines to do their job.
