Wire cutting machine tower crane lower chord joint
The tower crane's boom is one of the key parts of the tower crane. It is a structural weldment that is connected by a number of booms through the boom joints. The manufacturing quality directly affects the safety and life of the tower crane. In particular, the lower chord of the boom is the track of the force rod and the variable speed trolley. In order to make the car run smoothly, the two lower chords must meet the technical requirements of straightness, flatness, parallelism and verticality. Therefore, the manufacturing quality of the lower chord joint of the boom directly affects the manufacturing quality of the entire boom. This paper mainly introduces the use of wire cutting to process the lower chord joint of the boom, which provides a reliable guarantee for the improvement of the quality of the lower chord joint of the boom, while reducing the materials and simplifying the manufacturing process. 1.Proposing questions (1) The crane machine produced by our company (taking the QTZ80 tower crane as an example)
