What are the installation steps for crane beams?
The crane beam and track shall be corrected after the main component is fixed. Fix immediately after correction, in order of fixation, bolt first and then weld.
Installation of crane beam elevation as a negative deviation, between surface and column bracket crane beam flange into the iron plate. But the shim shall not exceed three layers and shall be placed under the end of the crane beam or under the stiffener, and the area of the shim shall not be less than 60% of the part of the contact area between the crane beam and the bracket.
Crane operation is relatively dangerous, the installation of crane beam should be standardized to ensure the safety of crane operation. How many points should I pay attention to when installing the crane?:(1) the actual elevation of the corbel should be measured before the installation of the steel crane beam, so that the construction error of the elevation can be adjusted when the crane beam is installed, so as to prevent the error accumulation.The installation sequence of crane beam is as follows: installing crane beam, installing auxiliary truss and installing brake beam.(2) crane shall be used by slings, lashing or reliable clamps. The binding point shall be determined according to the weight and length of the crane beam. Generally, the angle of the sling shall be greater than 45 degrees at the ends of the center of gravity of the crane beam.(3) should be placed after the crane beam, the connecting plate is connected with the fixed edge plate and column crane girder structure, to prevent the crane hook loose after crane girder longitudinal and lateral movement of dumping.(4) crane beam correction should be performed in all bolts after installation, to prevent the installation of bolts when the crane beam shift change; prohibited welding in the crane girder under the flange and web on suspension and fixture.(5) adjust the elevation of the crane beam, correct the center line and span after titanium.
