    ○  Pre-assembled

    ○  Each crane is pre-assembled to specifications before leaving the factory;

    ○  That is to pre-assemble on the pre-assembled special bridge frame, and use optical measuring instruments such as laser rangefinder, level, total station, etc. to test to ensure the correct span of the main girder camber, side bend, wheel alignment, diagonal line, etc. and positioning;
