There are three types of units that are widely used in China and local agencies in other country for Crack Sealing Machine. These include:
Trailer type unit;
Self-propelled unit;
Vehicular type unit.
In the trailer type unit, a dump truck pulls the trailer and feeds the aggregate through a modified tailgate into the trailer unit. At least two people, the truck driver and a person to operate the Crack Sealing Machine hose and nozzle are required. The Crack Sealing Machine operator works behind the trailer to control a delivery hose suspended from a boom on the rear of the unit.
With vehicular type unit, this eliminates the need for pulling a trailer, although the Crack Sealing Machine hose and boom are still operate from the truck.
As for self-propelled unit, the Crack Sealing Machine can walk along the operator instructions, which equipped with the imported brand engine, ensure the machine need the drive power.
