Described square tube 4 11, square tube 5 12 are X-shaped, and square tube 4 11, square tube 5 12 junctions are welded with liner plate 8.

Described square tube 29, square tube 3 10 are inverted V-shaped, and the junction of square tube 29, square tube 3 10 and square tube one is welded with liner plate 8.

The utility model is at first according to stress form and the direction of structure, structure has been carried out optimizing analysis, obtain a kind of truss structure form of optimum transfer path of power, optimizing on the results of analysis the further refinement of the size of structure and modification, obtain a kind of concrete version, carry out strength analysis, and with the contrast of the colligation bridge analysis result of conventionally form, stress cloud atlas and deformation pattern according to analysis result are made suitable adjustment to structure, thereby obtain a kind of the lightest and satisfy the colligation bridge form of performance requriements.Distortion of the present utility model and stress is all near allowable value, and less than allowable value, namely satisfies performance requriements, the most important thing is and can save about 20% material than the colligation bridge of conventionally form.

Principle of work of the present utility model is: operating personals such as lashing of container can arrive staircase 7 and climb up from first passage 6, second channel 5, arrive colligation passage 4 through manhole, one end of tie down system binding bar is connected on the colligation eye plate 2, the other end of binding bar is put the freight container container corner hole into, locking, freight container has just been pinioned.

The beneficial effects of the utility model are: structure is lighter, simple, and easy construction can better be satisfied operating needs.
