Edge Innovate has developed a new RTU2200 high capacity radial truck unloader, which will be showcased at the Hillhead exhibition (24 – 26 June 2014). The mounted unloader has been developed with feedback from dealers and end users and can be utilised in a variety of applications.

The RTU220 provides operators with a more efficient loading method, designed to allow continuous loading directly from trucks into train wagons or barges. The full HMI control panel and remote controlled functions provide operators easy control of the RTU functions whilst loading. The panel interface provides easy fine-tuning for accurate application performance while the HMI allows for automatic start/stop operation and provides visual data output, such as engine load, hydraulic oil temp and fuel consumption, while the machine is in use.

The RTU220 is an independent track mounted unit powered by a Cat 4.4 96 KW (129 BHP) diesel engine, offering huge torque whilst only consuming 12 – 15 l/h. Further cost savings are provided by a dual power option, allowing the loader to be tracked into position and then connected to an onsite 3-phase electrical supply to power conveyors at a higher level of efficiency.

The machine has a range of applications but is specifically designed to receive material from lorries and dump trucks. Its high torque drive system allows the speed of the conveyor belt to be adjusted, meaning the output of the machine can be regulated. Further applications include material stockpiling and loading of ships, containers and railway carriages.

Material is fed into the RTU220’s 23 m3 hopper and is carried to the radial conveyor via the 2200 mm wide heavy duty belt. Full-length impact bars prevent belt sag, reducing material roll back and prolonging the life of the conveyor belt. Variable belt speed via the HMI control panel controls the flow of material to the radial conveyor. The hopper capacity increases both cycle times and onsite production. With dual access hydraulic flared sides, the RTU220 hopper can be fed directly by wheel loaders and grab cranes – the sprocket and chain design ensure against belt slippage or stalling. It has the capacity to convey around 1000 tph with a maximum feed size of 600 mm.

Material is stockpiled via the 1200 mm wide radial product conveyor, which provides a discharge height of 6800 mm. The 140° radial function enhances the flexibility of the RTU220, allowing it to be utilised in a number of applications. The hydraulic folding head section allows for quick transition from transport to operating position.
