Movable seats

Abstract

A construction machine for the treatment of ground surfaces includes a chassis carrying a machine frame, a driveable work drum supported from the machine frame and including an outer surface and exchangeable tools fastened to the outer surface, a working space defined within the machine adjacent the work drum, and at least one seat for an operating person, the at least one seat being movable into a working position in the work space adjacent the work drum so that the operating person can exchange the tools on the work drum.

         30 : A construction machine for the treatment of ground surfaces, comprising:
 a machine frame;   a driveable work drum supported from the machine frame and including an outer surface and exchangeable tools fastened to the outer surface;   a working space defined within the machine adjacent the work drum; and   at least one seat for an operating person, the at least one seat being movable into a working position in the working space adjacent the work drum so that the operating person can exchange the tools on the work drum.   
     
     
         31 : The construction machine of  claim 30 , wherein:
 the work drum has a working width; and   the at least one seat is movable across the working width of the work drum.   
     
     
         32 : The construction machine of  claim 30 , wherein:
 the at least one seat is movable in a substantially horizontal plane both parallel to the working width of the drum and transverse to the working width of the drum.   
     
     
         33 : The construction machine of  claim 30 , further comprising:
 front and rear track assemblies; and   wherein the at least one seat is mounted to at least one of the rear track assemblies behind the working drum.   
     
     
         34 : The construction machine of  claim 30 , further comprising:
 at least two articulated pivot arms supporting the at least one seat for pivotal movement of the at least one seat about at least two vertical axes.   
     
     
         35 : The construction machine of  claim 30 , wherein:
 the at least one seat includes two movable seats positioned to access different portions of the work drum within the working space.   
     
     
         36 : The construction machine of  claim 35 , wherein:
 the two seats are pivotally supported on pivot arms from the machine adjacent opposite ends of the work drum.   
     
     
         37 : The construction machine of  claim 35 , wherein:
 each seat is supported by two articulated support arms.   
     
     
         38 : The construction machine of  claim 35 , further comprising:
 two rear track assemblies for supporting the machine frame; and   wherein each of the rear track assemblies supports one of the two seats.   
     
     
         39 : The construction machine of  claim 30 , further comprising:
 a drum housing surrounding the work drum, the drum housing including a lid; and   wherein the working space is located behind the working drum and is accessible via the lid of the drum housing.
