Operating concept

One-man operation from the cabin

Easy and convenient operation is a key principle of the KMA 220 / KMA 220 i. Pure ergonomics on the operator’s platform: the microprocessor unit with clearly arranged controls and illuminated display gives the operator full control of the plant at all times. All he has to do is key in the added quantities of water, bitumen emulsion, cement or foamed bitumen. The rest happens almost automatically. His spacious, weather-protected cabin offers an optimum view of the entire production sequence.

The operator has a good overview of the entire plant and can control all plant functions from the air-conditioned operator’s cabin.

Displays keep the plant operator up to date on important production details, such as the quantity produced as part of a lot in batch production. The intelligent control system registers any malfunction or material shortage and stops the plant, if required. Functions relevant for loading – such as start /stop production, tilt /vibrate vibrating grids – can be carried out by means of remote control.

Intelligent functions facilitate work

Field operation confirms that handling of the mobile mixing plant KMA 220 / KMA 220i is extremely easy. Many prudent detail solutions provide the time-saving effects and efficiency that are valuable assets. The screens on the proportioning hopper, for instance, are easy to clean and can be tilted continuously. The connection for the addition of hot bitumen is in an extra low position to ensure that the binder is drawn in properly even when the tanker truck is nearly empty. The hose and all other components transporting hot bitumen for the production of foamed bitumen are, of course, heated. The take-off conveyor below the material hoppers is completely covered, which helps to prevent the development of dust clouds. The belt of the take-off conveyor is continuously cleaned automatically by means of scrapers.
