Brushing and washing machine

A mobile brushing and washing machine for brushing and washing vertical and horizontal surfaces comprising:

• a base;
• means on the base for receiving the forks of a forklift truck;
• a vertically disposed cylindrical brush rotatable about its axis for contacting a vertical surface to be brushed and washed, said brush having an axle means mounting the axle of the brush to a frame so that the brush protrudes from the base;
• a tank mounted on the base for containing wash liquid carried by the base;
• a pump mounted on the base and having an inlet connected to said tank and an outlet connected to a line which returns to the tank and which is connected to the bottom of the tank through a fitting which agitates liquid in the tank as pumped liquid flows through the fitting;
• a plurality of spray nozzles disposed adjacent the brush and connected to the line for spraying wash liquid onto a vertical or horizontal surface to be brushed and washed;
• an adjustable valve in the line at a location between the fitting and the spray nozzles for adjusting the pressure in the line and in the spray nozzles;
• a hydraulic motor mounted on the framework and axially above the axis of the brush and directly connected to the upper end of the axle of the brush for rotating the latter, a further hydraulic motor drivingly connected to the pump;
• hydraulic lines connected at one end to the hydraulic motors and having opposite ends connectable to a hydraulic pump on a fork lift truck;
• said frame being pivoted at its lower end to said base, a hydraulic ram extending between an upper portion of said frame and said base so that the frame and brush can be pivoted from a vertical position to a horizontal position to wash the upper surfaces of a transport vehicle.
