Hose reel system

In a system having a source of water under pressure and a vertically and horizontally movable boom, a hose reel system comprising:

• a hose reel mounted to rotate about a first axis, said reel being fixed relative to said movable boom;
• a hose attached to said source of water and wound onto said hose reel;
• a first fairlead assembly mounted adjacent to said hose reel for guiding said hose from and to said reel, said first assembly rotatable with respect to said reel to maintain said hose perpendicular to the axis of said reel during payout and rewind of said hose;
• a hose traction wheel mounted to rotate about a second axis and being movable with said boom and in contact with said hose;
• a first drive motor operatively connected to said hose reel for rewinding said hose onto said reel;
• a second drive motor operatively connected to said traction wheel for paying out said hose from said reel;
• and
• a second fairlead assembly mounted to said boom adjacent to said traction wheel for guiding said hose from and to said traction wheel, said second assembly rotatable with respect to said traction wheel to maintain said hose perpendicular to the axis of said traction wheel during payout and rewind of said hose.

In a sewer and catch basin cleaner disposed on a vehicle and having an extensible boom rotatable horizontally and vertically with respect to said vehicle, a debris chamber, a vacuum system and vacuum hose, said vacuum hose carried by said boom, and a source of water under pressure, a water hose system comprising:

• a hose attached to said source of water under pressure;
• a hose reel having said hose wound upon said reel;
• a hose reel bracket attached to said vehicle, said hose reel supported about a fixed axis by said bracket;
• a first drive motor disposed on said hose reel bracket and connected to said hose reel by a first overrunning clutch, said first drive motor for rotating said reel in a direction to wind said hose onto said reel, said first clutch permitting said reel to turn freely in a direction to payout said hose from said reel;
• a first fairlead assembly attached to said vehicle adjacent to said hose reel, said first fairlead assembly having a first pair of sheaves mounted such that the peripheries thereof cooperate to grip said hose along a first axis perpendicular to the axis of said hose reel, said first pair of sheaves mounted to freely rotate about said first axis wherein said hose from said reel is passed through said first fairlead assembly;
• a hose traction wheel assembly mounted to rotate about an axis on a distal end of said boom and movable therewith, said wheel assembly having a hose traction wheel for paying out said hose;
• a second fairlead assembly attached to said distal end of said boom adjacent said hose traction wheel assembly, said second fairlead assembly having a second pair of sheaves mounted such that the peripheries thereof cooperate to grip said hose along a second axis perpendicular to the axis of said hose traction wheel, said second pair of sheaves mounted to freely rotate about said second axis, wherein said hose from said first fairlead assembly is passed through said second fairlead assembly and over said hose traction wheel;
• and
• a second drive motor disposed on said hose traction wheel assembly and connected to said hose traction wheel by an overrunning clutch, said second drive motor rotating in a direction to cause said hose traction wheel to pull said hose from said hose reel via said first and second fairlead assemblies, said second clutch permitting said hose traction wheel to freely rotate in a direction to rewind said hose onto said reel.
