ABSTRACT:
Disclosed is a fire hose washing apparatus which comprises: a casing; a fire hose washing portion having rotary brushes and provided in the casing and along a path for feeding a fire hose; nozzles for supplying washing water to the washing portion; and first and second fire hose feeding devices disposed separately from each other for a predetermined distance at positions on the fire hose feeding path in the downstream side of the washing portion with respect to the fire hose feeding direction. The fire hose passed through the washing portion is pulled out by the first and second fire hose feeding devices. A plurality of sensors for detecting metal connectors of the fire hose is provided at different positions on the fire hose feeding path so that upon detection of a metal connector by one sensor, the fire hose is pulled out by the second fire hose feeding device while stopping the hose feeding by the first fire hose feeding device. Upon detection of a metal connector by another sensor, the fire hose is pulled out by the first fire hose feeding device while stopping the hose feeding by the second fire hose feeding device. Thus, the first and second fire hose feeding devices are alternatively and alternately operated upon detection of a metal connector so that the hose is cleaned continuously regardless of existence of the metal connectors.
