Jan Hofmann with some of the company's latest technology
Hofmann says its new Line Width Stabiliser for existing one and two component airless guns ensures consistent road marking lines during changes of application machine speed.
“With a normal airless road marking machine, pumps have to go at one speed to get straight lines,” says Jan Hofmann, managing director of Hofmann.
“If you go fast the line gets thinner and wider, and if you go slower it gets thicker and narrower. With the Line Width Stabiliser, there is a constant thickness and width regardless of speed. This gives a constant quality.”
The airless pumps on Hofmann road marking machines sees paint applied to the road with over 100 bar pressure through a small nozzle.
Another new feature on the German firm’s road marking machines being exhibited at Intertraffic 2012 is the easy transferrable thermal plastic extruder head.
The Hofmann rota-table and swivelling extruder head allows for it to be switched efficiently from one side of the road marking machine to the other depending on which side of a road is receiving road marking paint.
“When you do road markings, it can take ten minutes to change the extruder head from one side of a machine to the other. This saves time,” says Hofmann.
Hofmann is also showcasing its new design H25-4 road marking machine for two component sprayable cold plastics, with a mixing ratio of 98.2%. The latest machine is said to have an innovative steering concept, achieving better straight-ahead driving with simultaneously improved shunting performance option.
Of the company’s current commercial success, Hofmann adds: “Business is good. We are selling worldwide and 90% of our sales are exports. Now many countries are investing in infrastructure.”
