Telestack Limited continues to excel in providing innovative mobile bulk material handling systems to its worldwide customer base. This has been emphasised in the manufacturing and development of fully mobile systems for loading barges and rail wagons directly from trucks, wheel loader and grabs. Telestack’s mobile unloaders are designed for a range of applications, with operators greatly benefiting from eliminating the double handling of the bulk material by unloading directly from trucks, wheel loaders and grabs to barges or rail wagons. These mobile solutions offer the performance in loading rates as well as the environmental qualities of a fixed installation. They also have the added bonus of greater flexibility and mobility on existing berths or rail yards, eliminating the need for dedicated infrastructure or civil requirements.
The complete range
The range of Telestack truck unloaders is extensive. All are customised to the needs of the particular client and operation, taking into consideration varying truck sizes, payloads, materials, cycle times, unloading rates etc. As with all Telestack products the mobility and flexibility of the units are the key features. The advantages of mobile systems are being recognised more and more in the industry, with port operators identifying the flexible mobile system as a viable option to replace expensive fixed installations which require civil work, planning permission and which are, in some cases, an ineffective loading procedure for both barges and rail wagons. The advantage of moving the mobile truck unloader off the site when it is not required is of great importance, especially when the port is not owned by the operator or it is a multi-cargo berth. Telestack’s mobile truck unloaders offer a range of mobility options for each individual requirement. The tracked mounted option, gives the operator unrivalled flexibility when moving around site as this unit is completely independent of all other systems. There is a diesel engine to drive all functions, with an optional dual power upgrade available. This allows the unit to be tracked into position and then plug in the three phase electrical supply to power the conveyor belts, limiting the diesel consumption of the units. There are also options for all-electric driven units for all functions, complete with integrated generator for a fully mobile unit. Rubber pads on the tracks and wheeled options are available to ensure that the concrete or asphalt surfaces are not damaged by the tracks. The greater mobility of these units also ensures they can be used in other applications within stock yards, mines and quarries if required, important considerations for possible re-sale value once contracts are finished. Wheeled options are available for a more basic unit which allows the operator or shipper to tow the unit around the site into each position. Telestack can also offer static versions, depending on the specific needs of the client.
Typically, the range of truck unloaders can handle trucks up to 50 tonnes payload (tipping or dump truck). The large hopper capacity increases cycle times which improves production rates. As there is such a wide range of trucks available in the market, Telestack can fully customise the hopper area to facilitate the most effective and efficient unloading area, including extended hopper sides, folding sides, flared designs, dual access, integrated fall break and many more tailored requirements. This ensures that the flow rate of each specific material and truck can be defined and taken into consideration during the design procedure. Also, the unloaders can be easily fed from wheel loaders and grab cranes for added flexibility. When handling dry bulk material, the dust suppression measures installed on the units ensure minimal dust emissions when unloading. The dust covers, dust extraction and telescopic discharge chute minimise dust emissions in the unloading area and discharge point to ensure a dust-free loading procedure.
All of the truck unloaders incorporate a heavy duty apron chain belt feeder, which ensures the surge of material discharging from the truck can be transferred and controlled onto the incline conveyor and barge, rail wagon or auxiliary equipment. Unlike other feeder conveyors who use rollers which would slip under the intense load in the hopper, the chain and sprocket driven belt, ensures there is no slippage and stalling of the feeder conveyor.
Mobile truck unloaders as part of mobile system
Telestack’s range of truck unloaders can also be used with their range of radial telescopic ship/barge loading conveyors. The combination of the mobile truck unloader and the mobile radial telescopic shiploaders offer the perfect loading operation directly from trucks to ship or barge. The radial telescopic technology offers unrivalled trimming capabilities without moving the truck unloading equipment.
