Available as trailers or for mounting on a carrier vehicle, Streumaster MC and TC binding agent spreaders from Wirtgen Group are designed for spreading efficiency and exceptionally precise results. The machines feature a high-speed filling device on both sides, self-cleaning dosing sluices and a new control panel.
The two large filling connectors at the rear of the units 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 or in moving traffic.
This enables filling to be carried out quickly and easily from either side of the binding agent spreaders. The combination of the improved high-speed pneumatic filling device and new container design enables filling at a rate of up to two tons-per-minute per connector while providing even distribution of the binding agent in the container. 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 is a standard feature that 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 provides precise discharge.
Thanks to the continuous comparison of the actual and target values during spreading, the spreading quantity is automatically readjusted in the event of a deviation from the required value. This almost eliminates the risk of operating errors.
The machines also feature self-cleaning dosing sluices in a cellular wheel design. These sluices incorporate a special housing with pressure and relief zones and flexible chambers that help keep the sluices clean.
A new multifunctional control panel design combines all control elements into one single unit and provides the operator with an overview of all machine functions at all times. The panel also offers 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 touch screen display.
This 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.
