PEBCO® began in 1977 designing and supplying equipment worldwide for controlling and loading dry bulk materials.

PEBCO®’s scope of supply and responsibilities include customized gates, valves, mass flow feeders, air slides dustless loading spouts, telescopic chutes, ship loading equipment, truck and train loadout systems.

PEBCO® is the owner of the North American Patent for the Cleveland Cascade® Chute. The design allows material to cascade from one cone to the next, minimizing dust generation for ship and barge loading.

PEBCO® designed and patented the Uni-Load® train and truck loading system for in motion loading of trucks and trains. This ground-breaking design allows for volumetric loading with accuracies approaching those of batching systems. In addition to engineering and building both volumetric and batch loading systems, PEBCO® has incorporated new innovative design modifications to our telescoping chutes.

PEBCO® has the experience of supplying over 40 in motion train loading systems worldwide ranging from rates of 2,500 tons per hour to over 12,000 tons per hour at speeds of between 0.5 mph to 1.5 mph. PEBCO® can custom design a loading system to meet our customer’s needs whether it be volumetric or batch loading with a telescoping chute or our patented Uni-Load® chute.

SOUTH AFRICAN TRAIN LOADOUTFully Automatic Volumetric 4,000 TPH Uni-Load® Loadout

Specified Accuracies: +2 tonnes / -1 tonne per railcar and +/- 1 tonne per railcar average for entire train

Located 90 miles northeast of Johannesburg, South Africa.•4,000 mtph volumetric loading system using a 60” square patented Uni-Load• ® chute delivery system to discharge and control flow into the railcars.A series of track scales monitor the weights of the empty and loaded railcars. This information is •provided in electronic format to the control system and used to make adjustments for the next railcar to be loaded in order to fine tune the loaded weight and centralize the load in the railcar.Loading an average of 3 trains per day with an average of 100 railcars per train. Due to rail restrictions, •railcars were required to be under loaded with the load centralized between bogie centers within +/-1,000 kg.

This mine is located in the Powder River Basin in the northeast corner of Wyoming near Gillette. This is a 7,000 TPH Batch Loading System using a (4) 60” square double-bladed slide gates to charge the weigh bin and a 60” square patented Uni-Load® chute to discharge and control flow of material into railcars. Average number of trains loaded daily is 6, average number of railcars per train is 120 and average load accuracies on 120 tons is +/- 500 lbs per railcar.

The control system incorporates a plc, pc, monitor, pedestal panel, automatic and manual controls as well as interface for network connections. The panels are laid out with ease of operation in mind. The Hydraulic Power Unit instrumentation is on the left, manual operation controls in the center and the automated controls and computer interface mouse and selection buttons are located on the right. An HMI screen provides the primary interface for the operator to monitor the overall process of loading a train.

For both volumetric and batching systems sensing the railcar height, railcar position and presence of the locomotive in the load out area are critical. These conditions and locations are verified by photo-eyes.

Wheel sensors are used to activate the track scales at the appropriate time to acquire railcar weights, trigger the Railcar Identification System and to generate a train speed indication.

An integral part of the system is the Railcar Identification System. This unit identifies the railcar number and allows the control system to associate the correct gross weight with the proper railcar.

Whether using a volumetric or batching system, a tare weight scale is used. Volumetric systems typically use a set of gross weight scales located at a position to establish the loaded weight of the railcar immediately after loading of the railcar is completed. This information is provided to the computer for adjusting the loaded weight of the railcar.

Electrical components are rack mounted in a control panel for ease of access. This allows for the use of plug in modular components.

The tare and gross scaleelectronic controls arehoused in a separate enclosure.
