Laakson Metalli has been
manufacturing slurrytankers more than 40 years - and vacuumtankers for
almost 30 years.
Even if the models of the tankers
has been changed during the years, it is still possible to easily
get spareparts also for the older tankers.
Lame vacuumtankers fullfill the
requirements of 'Machine Directive' and 'Pressure Equipment Directive'
of European Union. Every single tanker is inspected by certified inspection
The certificate of the inspection is delivered together with the tanker.
The maximum discharge pressure of
the tanker is 1,0 bar.
The tanker is designed for full vacuum (-1,0 bar).
The vessel has been welded on both
sides and the walls of the pipes are welded through.
We use only certified materials in
Vacuumtankers are manufactured in several sizes;
4700, 5800, 6800, 7900, 10000
ja 12000 litres, with different axle options. Biggest sizes are 1600mm
and 1450mm in diameter. Smaller tankers are 1340mm in diameter.
Wall thickness is 5mm, except biggest 3 sizes are made with 6mm tanks
ends (sidewall is still 5mm).
Tankers are equipped with 5000l/min vacuumpump. Optional
pumps are 8000 and 12000 l/min.
The spreading nozzle
gives even spreading result to whole width. The spreading width is 8 to
