Sweeper Pronar ZM-28H
The Pronar ZM-28H sweeper – is used for cleaning the surface of roads, pavements and squares. It can be also used for technological cleaning of the substrate before laying the asphalt layer. The working element of this machine is a cylindrical brush with a horizontal axis of rotation, driven by a hydraulic motor built inside the shaft. The working width of the brush is 2.8 m. The working brush consists of rings applied to a metal shaft. As the brush is worn out, it is possible to lower it by adjusting the support wheels. The garbage or snow discharge is limited by a front cover with a stepweis adjustable height. Operating the machine from the desktop in the operator’s cab simplifies the work being done. Sweeper Pronar ZM-28H is a machine mounted on the front of the carrier (agricultural tractor, wheel loaders, specialized vehicles), equipped with a lifting device, e.g. 3-point hitch.
Sweeper Pronar ZM-28H – features:
The working brush consists of rings applied to a metal shaft. Depending on the needs, you can choose straight segments – layered with spacers or bent, which after folding they form a sweeping roller with structure of honeycomb. Brushes can be different materials. On request, polypropylene (PPN) with two hardness classes, metal wire and joining these two materials are available.
Hydraulic engine driving the brush built into the shaft
The hydraulic engine is placed inside the shaft, which prevents its damage when hit in obstacle and reduces the overall size of the machine.
It allows to reduce the throw of snow or pollution. In addition, the ejection can be limited by mounting a rubber apron.
