Telestack Limited continues to excel in providing innovative mobile bulk material handling systems to its worldwide customer base. The success derives from achieving sustainable value for the client; using mobile bulk handling technology to enhance operational efficiency, minimize environmental impact and maximize flexibility.
Traditional ship-unloading in ports and terminals varies from the fully integrated ship to stockyard system incorporating grab cranes, hoppers, conveyors and stackers/reclaimers for fully dedicated berths. Alternatively, the system for multi-cargo berths operates grabs, hoppers, trucks to the specific stockyards. The main issue with the latter system, is how to efficiently stack the material in a safe and environmentally friendly manner? Telestack mobile stacking and truck unloading solutions are particularly effective when stockpiling multi-cargo in a remote stockyard which allow the customer to stockpile differing types and grades of materials in various locations.
For ports which operate multi-cargo berths/stockyards, Telestack’s unique mobile equipment can offer the flexibility to stockpile up to heights of 17 metres at a rate up to 2,500tph (tonnes per hour) using a range of truck unloaders and mobile radial telescopic conveyors. This automatic stockpiling system eliminates the segregation, degradation and compaction of the material within the stockpile, which ensures the material characteristics are maintained. Also, it can be used as a back-up stacking system in the event of failure or during statutory maintenance of a dedicated stacker/reclaiming system (see picture above and bottom left). This stockpiling unit can be installed with a crawler tracked dolly unit or wheeled dolly unit for full site mobility in harsh ground conditions. This site mobility ensures the operator can use this equipment anywhere within the stockyard when required. In many instances, these units are multifunctional, utilized for both stockpiling and shiploading applications up to Panamax-size vessels, with the radial telescopic features offering maximum manoeuvrability and flexibility during both processes.
In many applications, a fully automated integrated system would not be feasible to the particular port and inland terminal with lower capacities, which could not justify the high capital expenditure of the overland conveyor and stacker/reclaimer systems. As shown in the picture below, the popular method for multi-cargo berths would include grabs, hoppers, trucks to the specific stockyards. These trucks would transfer the bulk material directly to the stockyard. Primarily, these trucks would dump the material within the stockyard, then loading shovels or excavators would be used to stockpile the material, either with a loading shovels driving up and down stockpiles or a number of excavators used to achieve the required stockpile height and capacity, as shown in the picture below.
This is not an effective stacking method, with extensive contamination and double handling of the material, which leads to increased operational and production costs. The Telestack mobile solutions offer a range of mobile truck unloaders and stackers which can eliminate these common problems.
In specific stockpiling applications directly from trucks, Telestack offers a range of mobile truck unloaders which can transfer the load directly from the trucks to a stockpile. This unit can include a radial facility, which again allows maximum flexibility to stockpile up to 10 metres. This efficient stockpiling method eliminates the double handling of the material and allows the operator to stockpile directly from this single unit. Also, the mobility of this unit means it can be easily moved around the stockyard depending the requirements of the operator.
This range of truck unloaders can be used in conjunction with the radial telescopic stacker to achieve the greater stockpile height and capacity if required. The combination of these two mobile units for both stockpiling and shiploading, offer the customer complete flexibility, safety and efficiency, taking into consideration required stockpile heights, capacities and types/grades of materials within typical multi-cargo berths. The overall benefits of this range of equipment includes:
- dual functionality, both for shiploading and ship-unloading operations, which eliminates overhead costs for secondary equipment;
- ease of transport from stockyard to quayside; y range of truck unloaders utilized as a stacker/shiploader or feeding the radial telescopic stackers;
- wide range of dust suppression/containment and trimming facilities;
- operational movements range from in line, radial, parallel and many more;
- hatch changes normally only require parallel movement — no need to reverse out if the vessel is geared;
- cost-effective solutions compared to other competitors; and
- customized solutions to meets the needs of any application.
These mobile systems highlight Telestack’s aim to provide for the specific needs of each application to ensure the equipment is efficient and reliable during these types of operations, all from one experienced supplier.
Telestack will be exhibiting at the Bulk Ports,Terminals & Logistics 2012 conference and exhibition which will take place in Amsterdam, The Netherlands, from 20–22 May. Telestack’s factory sales team will be on stands 6 & 7, where they will be exhibiting the company’s full range of equipment of mobile bulk material handling solutions.
