Description

The invention relates to raft timber rafting and can be used by forest-rafting enterprises when transporting round logs that have limited buoyancy, especially hardwood and larch, in the waterways of the country.

The aim of the invention is to eliminate the costs of sorting out wood products with limited buoyancy from coniferous in the points of melting.

FIG. 1 shows a raft, a top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The raft consists of several rulers 1 in width, made up of timber 2

The linkage and the upper parapets 8 are connected along the sides of the raft and in the spaces between the rulers 1 by means of cable ties 12.

To ensure transverse stability of the rulers, their height and, consequently, the height of the raft is set depending on the width of the ruler formed from the shortest timber in a raft or, which is the same, on their length. Under conditions of stability, the raft height should be no more than 3/4 the length of short timber.

Let, for example, timber of three lengths 4.0 m, 6.0 m and 6.5 m enter the raft. Accordingly, the width of the rulers will have the same values. The height of the raft of certain types of timber and wood products 3 will be limited to 15 buccane conditions of transverse stability, which are installed in the most narrow ruler (4.0 m) and should not be perpendicular and perpendicular to more than 3, 0 m. Stability over towing, as well as forming lines, will be respected during this rigging. The formed raft for the belaying 13,

Claims (1)

A raft containing rulers composed of softwood bundled together and timber with limited buoyancy installed across the towing direction, connected by rods and parapets, characterized in that, in order to exclude the cost of sorting timber with limited buoyancy from coniferous Fig. 1 max of the float, as well as reducing losses, increasing the strength of the raft and the lateral stability of the rulers, coniferous forest products bundled into bundles are located in the lower part of the raft and are connected rigging rigging, and timber with limited buoyancy laid on them and fixed with longitudinal berths in the upper part of the raft, with additional parapets laid evenly on the upper and lower parts along the entire length of the raft, the lower ones being attached to the corresponding bundles of the lower part of the raft with parapet sets, and the corresponding upper and lower additional paraphernalia are interconnected along the sides of the raft and in the spaces between the rulers with screeds.
