  • Patent number: 5785516
    Abstract: A conveyable heating apparatus which is operable in a working place of repairing a paved road and can be carried on a vehicle. An asphalt-reclaiming apparatus 1 embodying one example of the heating apparatus comprises a combustion chamber 2 having an open top, a holding frame 3 supporting the combustion chamber 2, an oil pressure motor for rotating the combustion chamber 2, a stand 5 pivotally supporting through the holding frame 3 the combustion chamber 2, and an oil pressure cylinder 6 for effecting the inclination of the combustion chamber 2. The holding frame 3 is composed of a rear frame 3a disposed behind the combustion chamber 2, a lower frame 3b extending downward from the both ends of the rear frame 3a, and a pair of lateral frames 3c horizontally extending respectively from the rear frame 3a toward both sides of the combustion chamber 2. The combustion chamber 2 can be rotated by the oil pressure motor 4 and inclined by the action of the oil pressure cylinder 6.
