1. The conventional material is Q355B, and the enhanced version is Q460.
The plate is thin, high in strength, light in weight, and reduces the load of the excavator.
2. The bushing in the boom seat cover is made of copper (with self-lubricating carbon powder inside).
3. The oil pipes are all made of high-precision cold-drawn seamless steel pipes, which have undergone pickling and
phosphating treatment, with good material and high strength.
4. All the long arms are integrally bored after welding to ensure the concentricity between the pins and the quality.
