Crane beam manufacturing method

The invention relates to a crane beam manufacturing method. The method comprises the steps of: (1) screening of raw materials; (2) manufacturing of a bed jig; (3) leveling of cushion blocks; (4) manufacturing of a T-shaped beam; (5) manufacturing of a semi-finished H-shaped steel beam; (6) manufacturing a finished H-shaped steel beam; and (7) manufacturing of a crane beam. The method is scientificand precise, and is clear and logic in production operation; and multiple detecting methods are applied in the checking process for cooperation, and are performed in sequence to prevent the detectionmissing risk so as to guarantee high precision of the produced crane beam. 本发明涉及种行车梁的制造方法。该方法包括，下列步骤，步骤：原材料筛选，步骤二：胎架制造，步骤三：垫块抄平，步骤四：T型梁制造，步骤五：半成品H型钢梁制造，步骤六：成品H型钢梁制造，步骤七：行车梁制造。该方法科学、严谨，生产操作条理清晰，检查过程中运用多种检测办法相互配合，有序进行，规避漏检的风险，确保生产出的行车梁精度较高。
