2. The deviation of the plane elevation relative to the height of the two crane beams shall not exceed 10 mm at the column and 15 mm at other places; the elevation of the top surface of the crane beam shall be (10,-5) mm.
3. The deviation of the crane's centerline position to the design positioning axis shall not exceed 5mm. The reference centerline and column edge dimensions of each crane beam must meet the following requirements: lifting weight Q ≤ 50t, the size is b60mm; lifting weight Q is 50~100t, the size is b100mm, where b is the distance from the center of the track to the outer end of the crane .
4. The crane is the top level of the crane beam in the 400mm wide range of the bolts ≤25mm; the difference of the top surface height of each bolt in the 6m length of the beam is ≤±3mm; the height difference of the top surface of each bolt along the length of the workshop ≤±5mm; and check whether the reserved hole is skewed or blocked.
5. The concrete grouting layer between the concrete crane beam and the track of the crane should meet the actual regulations. The top surface of the crane beam should be washed clean before pouring.
