electric overhead crane

Calculating local bending moment caused by wheel pressure in the first quarter. When CHS center of gravity axis of the intersection point of the string section centroid eccentricity, double girder overhead travelling crane to calculate its impact. Check the strength of each bar, hydraulic components and the stability of the axial compression member and fatigue of the bar. The node must carry on the strength and fatigue calculation. To check girder crane beam and brake structure deformation. The slenderness ratio of member to conform to the requirements of the specification. Crane beam arch camber to reduce large span crane beam may arise when using large downward deflection phenomenon, electric overhead crane to avoid affecting the normal operation of the crane, and in the production of crane beam, beam arch up in advance. When deciding the arch since size, want to consider the convenience of crane rail laid.
