Cracksealing machines 300l and 500l

Intended use:

  • Sealing bitumen mastic structure edges with bituminous crack and joint sealant, bitumen, etc.
  • Joints between bitumen mastic strips
  • Filling joint gaps in roads, airports, bridges and flyovers
  • Repair of bituminous and concrete pavement cracks
  • Sealing tram induction loops etc.

Materials used:

  • sealing compounds in solid form(cubes)
  • sealing compounds in liquid form
  • asphalt – also modified with polymers,
  • sealing compounds as Bornit etc.,
  • bituminous emulsions, etc.

Principle of operation:

  • safe and simple sealant loading through angled doors provides splash-proof loading.
  • mass is heated in oil-jacketed tank indirectly and dissolved into a working form without the risk of overheating or burning.
  • during the heating of the mass the manual lance with wire is initially heated in a starting chamber.
  • the heated in the tank sealing compound is given by the pump through a wire with manual lance into the gap.
  • amount of mass flowing out of the lance is adjustable by valve.
  • the machine can be equipped with a built-in compressor used for cleaning the cracks with compressed air before filling.
