发明名称 Multi axial asphalt heating system with up and down, forward and reverse adjustments and fold up feature adjustment
摘要 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.
