10 a cylindrical roller 11 and a roller support structure 12 although the truck 10 shown is of the dump type typically used in cities for snow removal and salt application and for road repair work no particular type is critical it is only essential that the particular truck be capable of bearing the loads created by the roller 11 and support structure 12 as described more fully below snow removal type trucks are advantageous in that such trucks already have much of the necessary framework and hydraulics for useful employment with the roller 11 and support structure 12 of the present invention thus the present invention provides a means for more efficient year round utilization of city work trucks the roller support structure 12 shown in greater detail in fig2 and 3 includes truss beams 13 and 13a and braces 14 and 14a which are attached to the truck frame 15 at the front end 16 and on each side of the truck 10 and which bear the loads during rolling additional reinforcement and integration of the structure 12 is provided by a u shaped angle iron framework 17 the corners 18 and 18a of which are joined to the truss beams 13 and 13a and the ends 19 and 19a of which are joined to the braces 14 and 14a flanges 25 and 25a at the corners 18 and 18a and the braces 14 and 14a at the ends 19 and 19a of the framework 17 project forwardly therefrom thereby supplying places for attachment.
