The invention relates to shipbuilding and can be used for the transport of large-panel tons of human cargo.

. A well-known barge for transporting large-panel tons of cargoes, comprising a hull, on the deck of which is dimensioned; the support structure, including longitudinal and transverse beams, is a disadvantage. The design drawback is the difficulty of loading and unloading. ;

The purpose of the invention is to simplify loading and unloading.

This goal is achieved by the fact that in a barge for transportation of large-panel tons of cargoes, comprising a hull, on the deck of which a support structure is placed, including longitudinal and transverse beams, the support structure is equipped with working platforms inclined to the horizontal and lower upper and lower ynopHj the angle oi of the slope of the platform is chosen from the condition

oi g arctg f - 3 - when the plasterboard tilts to the tip of the barge,

оС g, arctg f + 3 - when the platform is tilted to the middle of the barge, where f is the coefficient of friction of the load on the inclined platform. ....

FIG. Figure 1 shows schematically the proposed barge, a bolted version with two supporting structures and an inclination of the platforms to the extremities; in fig. 2 - the same view. from above; in fig. 3 - the same side view (a variant with two supporting structures and an inclination of the platform to the mid-section),. ..

The barge includes hull 1, on the deck of which a support structure 2 is installed, consisting of longitudinal and transverse beams. At the transverse edge of the supporting structure 2, there are inclined platforms 3, limited by the upper 4 and lower 5 stops, inclined to the horizontal at an angle determined by the conditions

(X, $ arctg f - 3 (when the platform is tilted to the tip, i.e.)

01 t arctg f + 3 (at inclination Sh1op; adki to the middle, i.e. x - agO), where f is the coefficient of friction of the load on the inclined platform:

X load shoulder from midsection: distance relative to

And midley to the bottom. edge of the front plane of the cargo installed on an inclined platform.

The handling operations are produced as follows.

When loading, the cargo in a vertical position is transferred by the crane to the area of the inclined platform, where its position is fixed by the stops 4 and then it is placed on the inclined platform 3 and lowered onto the supporting structure 2.

; When the ba; rye is unloaded, the load is lifted by the crane to the inclined platform 3. where its displacement is limited by the platform and the abutment 5 itself, and then set to a vertical position.

The effectiveness of the invention is to reduce the time of cargo operations, reduce energy costs and the number of staff.
