Description

Technical Field

[0002] The applicant's prior patent application with patent application number "202111549138.3" discloses a wire rod roll transfer vehicle, which limits the wire rod roll on the supporting seat by setting a front limit mechanism and a rear limit mechanism to prevent the wire rod roll from tipping forward or backward. The movable limit member in the rear limit mechanism can move along the length direction of the supporting seat, thereby adjusting the length of the accommodating area formed between the movable limit member and the rotating swing arm to accommodate wire rod rolls of different lengths.
