UNIT TRAIN BATCH LOADING SYSTEM

PEBCO® Inc. in collaboration with FGR Automation & Controls has developed a fully Automated Train Batch Weighing and Loading System. This system has been successfully implemented on a variety of materials including coal and coke. Trains pass through the loadout at a pre-determined steady speed and do not stop as they are being loaded. Each batch is calculated based on the maximum gross weight and the empty tare weight. Individual car data is obtained either from a master database or via a radio frequency badge installed on each car. Actual weight loaded into each car is recorded in a database for the manifest, which is transmitted electronically for billing on completion.

The loading system structure consists of a surge bin directly over the rail loading point. The railcars are flood loaded based upon time, and a net weight is determined. When the unit train approaches the loadout, the track scale automatically weighs each empty railcar. The entire unit train less the locomotives are left on the siding. The locomotives then re-enter the main line and reattach to the last cars. The train is then loaded so that the last tare weight now becomes the first car to be loaded.

The track scale is located 1/2 car length from the loading point. Since the cars are being loaded based upon time, a key parameter is a loading system with fast acting gates and no transcient coal stored in the chute. The Uni-Load® chute was chosen for these reasons.

Since the Uni-Load® chute cutoff gate is located at the bottom of the chute, transcient coal is eliminated. Transcient coal often exceeds 10,000 pounds in convention loading systems.

PEBCO® is recognized worldwide as a manufacturer of powder and bulk solids equipment. Products produced range from truck, train, and shiploading equipment to gates, valves, diverters, mass flow feeders, Cascade® chutes, dustless loading spouts, and telescopic chutes. PEBCO® acquired Cleveland Armstrong® in 1983 to complement its line of equipment.

PEBCO®’s capabilities range from application engineering, CAD design, manufacturing, start-up services, and a complete customer support program.
