DETERMINATION OF THE COMPLIANCE OF CARGO WITH THE
DIMENSIONS IN RAILWAY TRANSPORT AND THE PERMITTED LOADS
FOR SEMI-OPEN WAGONS AND PLATFORM ELEMENTS

Keywords: Gauge, semi-open wagon, platform, permissible load, gauge limit,
rolling stock, technical specifications, fastening means.
Abstract: The article shows the determination of the compliance of the cargo
with the dimensions and the permissible loads on semi-open wagons and platform
elements in railway transport during the delivery of goods. Rolling stock for freight
transportation is studied, measures and proposals for their selection are developed. In
addition, the technical characteristics of the main models of wagons are analyzed, and
proposals are made on the permissible loads on semi-open wagons and platform
elements to eliminate the shortcomings of the existing system.
Introduction.
A load loaded into a single wagon or a combination of two
wagons is considered to be oversized if none of its parts, including packaging and
reinforcement elements, exceeds the limits of the basic loading dimensions and the
distance of the load, including packaging and reinforcement elements, from the
transverse plane of symmetry of the wagon (or combination) to its ends does not exceed
the values specified in Table 1.
Main part. Checking the compliance of the load with the gauge should be
carried out in conditions where the wagon is located on a straight and horizontal
railway section and its longitudinal vertical plane of symmetry coincides with the
railway axis.

It is not allowed to load the upper and middle lashing devices on the same
support at the same time.
Conclusion. It is not allowed to fasten the tensioners and ties to other parts of
the wagon div, including wooden brackets, fastening rings located on the upper
connecting beam of the semi-car, as well as to the rings on the outer surface of the
platform side sections. It is allowed to use wire tensioners and ties consisting of several
components or combined tensioners and ties consisting of various types of tensioners
and ties. The strength of the connecting elements of such tensioners and ties must not
be less than the strength of the individual components. Ties on the platforms are
fastened to the supporting brackets located opposite.
