Abstract
A multi axial asphalt heater for re-heating and recycling of old and new asphalt for permanent joint free repairs and restorations. It is possible to adjust the heating elements mechanically up and down off the asphalt surface with the lever arm mechanism. The provision of rotational movement of the heating elements permits the device to be retracted into a transport configuration. Forward and reverse motion of the heating elements permits a graduate heating process to be performed. The fold-up design with radially shaped adjustable hinges provide various angularity adjustments not only for compact convenience but also for establishing specific heat clearances, avoiding shut down delays and overheating.
Claims9
A portable, walk behind, pavement heater, having a self-contained fuel source and a wheeled frame, the pavement heater comprising:
- A heating assembly having multiple heating elements pivotable about respective pivot axis from a retracted, transport configuration, to an extended operational configuration;
- as well as,
- A track rail extending along a longitudinal centerline of the pavement heater and a;
- Motorized trolley, connect to the heating assembly, and having a reduction gear mechanism, for selectively moving the heating assembly fore and aft, along the track rail;
- A track rail pivot assembly, to permit the track rail to be pivoted upwardly and rearwardly, into a retracted position, and pivoted downwardly into an operating configuration.
A portable, walk behind, pavement heater, having a self-contained fuel source and a wheeled frame, the pavement heater comprising:
- A heating assembly having multiple pivotable heating elements;
- the heating assembly further comprising:
- A pivotable track rail extending along a longitudinal centerline of the pavement heater;
- A motorized trolley, connect to the heating assembly, and having a reduction gear mechanism, for selectively moving the heating assembly fore and aft, along the track rail,
- At least one lever arm, operatively connected to the heating elements, and are manually manipulated to both raise and lower the heating assembly relative to the surface being heated.
