  • Patent number: 4403424
    Abstract: A drier cabinet for drying fire-hoses of other similar hoses comprises an elongated horizontal receptacle (10), in which a plurality of hoses (19) may be placed side by side in extended positions to undergo drying in said receptacle. In order to permit a continuous operation of the drier cabinet, the receptacle (10) is divided into two parallel drying chambers (11), extending in side by side relationship along the length of the receptacle. At their upper ends, the drying chambers (11) have longitudinally extending openings which are individually closable by means of appurtenant covers (13). The two covers (13) are rigidly mounted on a common rotatable shaft (14), located between them and connected to a single driving motor (16). Additionally, the two covers (13) act as counterweights for each other to reduce the required driving power.

  • Patent number: 4348781
    Abstract: A hose cleaning plant comprises an elongated horizontal receptacle (10) in which a number of hoses (16) may be placed side by side in extended positions, washing equipment (13) provided at one end of the receptacle (10), and a transport device (18) which is movable along the receptacle to draw a hose (16) through the washing equipment and along the receptacle (10), above the same. In order to make it possible, upon completion of a washing operation on a hose (16), to have the hose laid down in proper position in the receptacle (10) without considerable manual efforts, said transport device is formed by a carriage (18) which is supported on rails (19), provided adjacent to the longitudinal upper edges of the receptacle (10), and which is provided with means (20) for releasably holding an end portion of a hose (16) in a selected position in the transversal direction of the receptacle (10).
