Five-brush Panda commercialvehicle washers from J. S. and L. Birch (Engineering) are said to require 20 per cent less space and to wash a vehicle in 20 per cent less time as compared with the concern's three-brush designs. The latest is the P61 which is capable of washing in a 22ft wash bay vehicles up to the length of a 1-ton van.
The Panda P61 will wash all sizes of c.v. from a Morris 1000 van up to a 14ft high pantechnicon; a maximum width of 8ft 6in. can be accommo„dated .
A steel gantry. incorporating water sprays and carrying one top and four side brushes runs On a simple track. The side brushes are designed to have constant contact with the vehicle
and brush pressure is applied by pneumatic cylinders. The top brush is the contour type and is designed to maintain contact with all horizontal surfaces; it will even wash underneath front and rear bumpers.
All control equipment is carried on the gantry and when the top brush is moving up or down, the gantry stops. This enables a fine wash to be achieved on the front and back of vehicles. Models are available for manual or fully-automatic operation and all units are fitted with overriding controls to enable ladder racks, light signs and the like to be washed without damage.
Brushes are spirally wound onto solid or tubular shafts, the ends being fastened with 0.25in. hook bolts. The PVC cruciform monofilm bristles are set in galvanized-steel strip and the bottom sections of the side brushes are replaceable without renewing the whole brush.
