Calculation of the transverse frame for horizontal loads

The frame is calculated by four independent loads from the action:

- horizontal wind load;

- cranes pressure in their disadvantageous position;

-horizontal force arising during cross braking of crane trolley;

-unit force P = 1 applied at the level of the crossbar in the horizontal direction.

Calculation of the transverse frame taking into account the spatial work of the frame

We make the final calculation of the frame with an endless stiffness crossbar for crane loads taking into account the spatial work of the frame. In this case, the flat frame is calculated under the combined action of crane loads and the equivalent force F applied horizontally at the crossbar level.

Design and calculation of enlargement units

The farm is delivered to the construction site in the form of two sending units connecting in nodes 7 and 14. Pre-assembly is carried out by welding the taurus of the upper or lower belt of one sending unit to the shape belonging to the second sending unit.
