High-speed filling, new controls on updated binding agent spreaders from Wirtgen

New models of Streumaster binding agent spreaders from Wirtgen, designed as trailers or for mounting on a truck, feature a high-speed filling device on both sides, self-cleaning dosing sluices, and a control panel, all of which guarantee spreading efficiency and precision.

The two large filling connectors at the rear are fitted as standard equipment and allow silo trucks to drive up close to the machine to fill the container, even when space is limited. Filling can be carried out quickly and easily from either side of the new binding agent spreaders.

The combination of improved high-speed pneumatic filling device and new container design ensures fast filling and even distribution of binding agent in the container. The spreader can be filled at a rate of up to 2 tons per minute per connector. An optional automatic filter system can also be fitted to enable dust-free filling. The integrated OptiPower chain conveyor drive with automatic load control fitted as a standard feature increases the tensile force on the conveyor chain whenever necessary.

Fully automatic volumetric dosing of the spreading quantity, independent of the travel speed, enables consistently reliable discharge of the binding agent. At the same time, the optional WeighTronic weighing device guarantees correct and precise discharge. Continuous comparison of actual and target values during spreading allows for automatic readjustment if sensors detect a deviation from the required value. This automatic system reduces operating errors.

Thanks to a special housing with pressure and relief zones and flexible chambers, the dosing sluices are self-cleaning units. This guarantees consistently high spreading efficiency and accuracy. The spread rate can also be individually adjusted for each of the three partial spreading widths.

A new multifunctional control panel combines all control elements into one single unit that gives an ideal overview of all machine functions at all times, while also providing a customizable user interface with a split-screen function when using the camera/monitor system. Operators can set up and save individualized operating parameters and function keys on the user interface of the 12-inch touchscreen display.

The new generation of binding agent spreaders can be equipped with Wirtgen Performance Tracker - WPT. The system registers all relevant location-specific working parameters to provide a comprehensive database for the analysis and documentation of the job site.
