| Abstract: | The longitudinal stability of the bridge erecting machine is directly related to the safety of the workers and the equipment at the construction site,and the longitudinal stability of the bridge erecting machine is directly related to its structure type,beam erecting technology and construction site. This paper analyzes the structural characteristics and beam erecting technology of DJ type bridge erecting machine,in addition,the longitudinal instability risks of beam erection,through hole and end hole erection are analyzed in depth,and the corresponding preventive measures are made for these risks,which is of great practical significance to ensure the operation safety of this type of bridge erecting machine. |
