Schmidt ｜Street Sweeper｜Wasa 300⁺
Sweeping technology
The sweeping unit of the Wasa 300+ consists of two towed disc brushes with brake-back protection and wear-free direct drive via an hydraulic motor. The hydraulic lifting and lowering of the disc brushes, and hydraulic brush ground pressure, can be controlled via the control panel. The Wasa 300+ has a rear-mounted roller brush and enables a wear-free direct drive of the roller brush via the hydraulic motor. An innovative, adjustable roller brush cover ensures optimum sweeping results.
Suction system
Two disc brushes mounted on the sides in front of the axle transport the debris to the centre; the roller brush located behind the axle transports the debris to the generously proportioned hopper via a broad elevator. The high throughput rate of the elevator is ensured by the 60° fitting position and the continuously variable transport speed control. The smooth running of the elevator is ensured by a top-mounted hydraulic motor.
Water system
The non-corrosive plastic water tanks, mounted left and right, have a total capacity of 1,100 litres, and can be swung outwards for cleaning and maintenance work. Meanwhile, the 12 spray nozzles of the sweeping unit are supplied by a hydraulic water pump with a flow rate of up to 36 l/min.
Sweeping material hopper
The Wasa 300+ has a steel hopper with a 3 m³ capacity. The discharge height is 1,750 mm. The hopper is tipped hydraulically, while an hydraulically extendible support additionally protects the vehicle from tipping over. The hopper’s conical shape is optimised to ensure safe and quick discharge.
Operation
All functions are conveniently operated from the vehicle cabin via a logically-arranged control panel. All relevant information is displayed on the graphic display.
Drive
The Wasa 300+'s hydraulic system is driven by the PTO (power take-off) of the towing vehicle. The oil temperature is monitored by sensors and a warning message is issued if the temperature is too high or too low.
Drawbar
For the Wasa 300+ both bottom or top coupling is available. A slim drawbar enables outstanding manoeuvrability and a large steering angle, while various drawbar eyes and an optional hydraulic swivel drawbar are also available.
