Operating rules for bridge erecting machines
Six, after the erection of the bridge crane must be suspended hanging crane operation, but also can be used to test the concrete beam, bridge erection machine running in place to start the installation work.Seven, bridging machine installation work, we should pay attention to the safety inspection, each installation of a hole must conduct a comprehensive safety inspection, found the problem to stop working and timely processing to continue to work. Do not allow mechanical and electrical failure.Eight, the installation operation is not allowed to overload operation, shall not lift operation.Nine, connecting pin processing materials must be carried out according to the requirements of design drawings, shall not use the low grade instead of processing.
Three, bridging machine longitudinal movement to do all the preparatory work, requires a place, not allowed to stop halfway.Four. When the bridge crane carries the concrete beam, the front leg part of the bridge crane is required to be fixed by the hand pulling block (5T).Five, when installing the bridge with the upper and lower longitudinal slope, the longitudinal displacement of the bridge erecting machine should be prevented from sliding. For example: the triangle iron for protection on wheels before and after, especially in the leg from the beam end is near, shift to the attention of control.
The vertical height of the longitudinal running rail of the bridge erecting machine is corresponding to the height requirement, and is stable. Front, middle and rear legs of the horizontal running track requirements, and strictly control the spacing, the three tracks must be parallel.
Two, concrete skew bridge girder erecting machine installation, before, during and after a leg wheel position, left and right wheels to staggered around, the distance can be calculated according to the skew angle, so that the leg wheel can run on the same horizontal track (for details please contact with the manufacturer).
