Project Description

The main task of wagon liner – exclude cargo wetting and spillage!

Wagon liners aimed at the creation of such cover goods technologies in open wagons, which would isolate it from the external environment, and localize the load, excluding the product’s chemical reaction with the environment, its “natural” decline due to spillage or blowing. In addition, the liner is unpacked carriage way that prevents unauthorized access to the product and makes it difficult from the opened gondola car as well as it eliminates moisture under the influence of rainfall.
The reliability of the wagon liner use to prevent spillage, is shown in the video material “Protection from spillage K4”. We have been specially selected wagon with through holes at the bottom, the size of which reaches up to 300 mm wide and 1500 mm long. Efficiency of wagon liner “K4” was 100% (look at video)

Protection from spillage

In spite of the wagon liner successful construction, consumers more and more often complained of moisture through the liner. Despite the fact that the liner is made of a laminated polypropylene, which holds moisture, in the rainy weather the cargo becomes partly wet through the liner’s seams.
For wagon liner improving, our experts developed SEAM SEALING. Such sealing ais directed to avoid moisture penetration through the seams of the liner (Frequently moisture enters the space punched by needle in the manufacture of the liner) .Wagon liner with seam sealing is a guarantee of dry cargo during transportation.
This type of sealed seams has been successfully used to transport soil, oil meal and other fine-grained products!
The liner for the railway wagon is approved and widely used by shippers during bulk transport of such products as burnt lime, sodium silicate (silicate lump), mineral concentrate halite (salt). In accordance with the Rules of transportation of dangerous goods by rail, transportation of ammonium nitrate is permitted in open-top cars packed in covered wagons. But because of the impossibility of mass transportation of cargo in covered wagons it is necessary to transport it in a gondola wagon with additional safety tools – the wagon liner.

The company also produces a wagon liner that is equipped with upper loading valves using an internal all-welded polyethylene flask for 100% protection of the cargo against possible wetting and spillage.

Product unloading is made through wagon lower hatches using cut opening of woven liner material. Using this method significantly reduces the preparation time of wagon loading and does not require stripping it after discharge of the product.
“It was found that during the transportation of fertilizers in bulk corrosion speed of wegon walls may reach 0.1 mm per year.”
Upon request, the liner structure can be modified.

ADVANTAGES

image47
Using laminated liner with sealed seams, eliminates wetting of cargo and gives an advantage over the use of hopper wagons.
image49
Wagon liner is made of polypropylene and is completely suitable for the transport of foodstuffs.
image51
Using a liner in the wagon against the soft containers and big bags reduces the the bulk cargo transportation price, as eliminates the stage of product packaging, its handling and unloading of the gondola wagon.
image53
The liner in the wagon corresponds to the scheme of placing and securing shelters of bulk cargo in a 4-axle gondola wagons.
