In terms of how the unit deployed in Colombia has been designed, it was based on a proven standard developed by Telestack, then customized to meet the specific needs of the application.
The tipping point, for example, has been custom designed for the customer’s trucks to ensure that no spillage occurs during loading and that there is continuous feeding, resulting in a regular truck cycle time.
The SPRB unit also incorporates a dual power electric supply, which means operating costs can be kept low. Under normal circumstances, the barge-loader is driven around the site and operated via the integrated CAT 96.4KW diesel hydraulic engine. However, to minimize fuel consumption, an integrated electric system allows the conveyor belts to be driven electrically from an on-shore power supply.
Telestack’s engineers have also made sure the unit has been optimized to handle grain in the most efficient manner possible. So, chevron belts have been fitted to ensure the free-flowing of material. In respect of environmental protection, the unit offers integrated dust enclosure around the tipping area, as well as dust covers on the incline conveyor and a fully enclosed discharge chute to direct the material into the barge.
“Understandably, the harsh marine environment of Barranquilla Port was of concern to the customer. However, we have applied a 250 Micron (marine grade) paint finish with integrated zinc primer to the finish of the barge-loader, thereby ensuring maximum protection,” says Donnelly.
He points out that Barranquilla is very much a multi-purpose port, handling both dry bulk and containers, so the mobility of the barge-loader was critical, since the operator has to be able to move the unit off-site when needed and easily transport it from site to site as ro/ro (roll-on/roll-off) cargo load, if required.
Rather than fit conventional wheels to the barge-loader, the customer opted for tracks, which incorporate rubber pads. This has been done to ensure that no damage is inflicted on the asphalt or concrete surface of the quayside on which it operates, but allows easy movement of the equipment.
The use of the all-function radio remote control also allows the operator maximum flexibility when moving and operating the unit, especially when trimming out the barge. For example, the unit can be positioned at many different angles, depending on the size of the barge and discharge point of the trucks/wheel loaders.
Based on the use of 25-tonne trucks, this specific barge-loader has a loading capacity of 300–400tph (tonnes per hour) when handling grains at 0.7 tonnes per cubic metre.
Finally, in respect of Telestack’s after sales support, Donnelly, points out that the TU 515R barge-loader is being supported and maintained by a local representative on this project, Gestio´n y Gerencia de Proyectos Consultorias (GGPC), which is based in Barranquilla.
“This company is vastly experienced in this industry, currently supporting other, similar brands, such as Terex Gottwald and Kirow, in Colombia. Going forward, the equipment will be continually supported locally in terms of maintenance, operation and spares provision to ensure the effective long-term success of the project,” says Donnelly.
Telestack’s range of equipment is working in a variety of applications including coal, iron ore, aggregates, fertilizers and grain. They have reference sites across the globe in mines, ports, quarries, power plants, steel mills and cement plants and a team of specialists to support all projects.
Telestack specializes in the complete design, manufacture, installation and commissioning of mobile, bulk material handling systems.
Telestack have a global proven record in a range of applications including the coal, mining and quarry industries, stockyard management, ports and inland terminals, power stations, rail yards, steel mills, cement kilns and many other bulk material handling industries.
