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.
Claims12
1:
- A construction machine for the treatment of ground surfaces, comprising:
- 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 working space adjacent the work drum so that the operating person can exchange the tools on the work drum.
3 more elements
2:
- The construction machine of claim 1, wherein:
- the work drum has a working width;
- and
- the at least one seat is movable across the working width of the work drum.
1 more element
3:
- The construction machine of claim 1, 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.
4:
- The construction machine of claim 1, wherein:
- the chassis includes front and rear track assemblies;
- and
- the at least one seat is mounted to at least one of the rear track assemblies behind the working drum.
1 more element
5:
- The construction machine of claim 1, 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.
6:
- The construction machine of claim 1, further comprising:
- an auxiliary drive operably associated with the work drum so that the auxiliary drive can rotate the work drum when the work drum is in a raised condition;
- and
- a remote control for the auxiliary drive, the remote control being attached to the at least one seat for movement with the at least one seat.
1 more element
7:
- The construction machine of claim 6, wherein:
- the auxiliary drive includes a control unit activatable by the remote control, the control unit operable to limit rotation of the work drum to a predetermined maximum angular rotation upon activation of the auxiliary drive by the remote control.
8:
- The construction machine of claim 1, wherein:
- the at least one seat includes two movable seats positioned to access different portions of the work drum within the working space.
9:
- The construction machine of claim 8, wherein:
- the two seats are pivotally supported on pivot arms from the machine adjacent opposite ends of the work drum.
10:
- The construction machine of claim 9, wherein:
- each seat is supported by two articulated support arms.
11:
- The construction machine of claim 8, wherein:
- the chassis includes two rear track assemblies;
- and
- each of the rear track assemblies supports one of the two seats.
1 more element
12:
- The construction machine of claim 1, 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.
