Abstract
A construction machine for the treatment of ground surfaces includes a machine frame, a drive motor, a work drum supported from the machine frame and including exchangeable tools fastened to the work drum, a belt drive and an auxiliary drive. The belt drive includes a motor-side pulley connected to the drive motor, a drum-side pulley connected to the work drum, and at least one drive belt connecting the motor-side pulley to the drum-side pulley. The auxiliary drive may be permanently coupled to the belt drive, or the auxiliary drive may include an adjustment mechanism for moving the auxiliary drive between a coupled and an uncoupled position.
Claims20
A method of manufacturing a construction machine for the treatment of ground surfaces, comprising:
- (a) providing a machine frame;
- (b) mounting a drive motor on the machine frame;
- (c) mounting a work drum on the machine frame;
- (d) connecting the drive motor with the work drum via a belt drive so that the drive motor rotates the work drum at a first rotational speed when the drive motor is activated;
- and
- (e) coupling an auxiliary drive to the belt drive so that the auxiliary drive can rotate the work drum at a second rotational speed less than the first rotational speed when the work drum is in a raised condition out of engagement with any ground surface.
A method of operating a construction machine for the treatment of ground surfaces, the construction machine including a machine frame, a drive motor mounted on the machine frame, a work drum supported from the machine frame, a plurality of exchangeable tools mounted on the work drum, a drive line connecting the drive motor to the work drum, an auxiliary drive operably mounted on the machine, and a remote control mounted on the machine for controlling the auxiliary drive, the method comprising:
- (a) driving the work drum with the drive motor via the drive line and thereby rotating the work drum at a first rotational speed;
- (b) engaging the work drum with a ground surface and working the ground surface;
- (c) raising the work drum from the ground surface to a raised position;
- (d) replacing some of the exchangeable tools on the work drum;
- (e) actuating the auxiliary drive via the remote control and driving the work drum in the raised position with the auxiliary drive at a second rotational speed lower than the first rotational speed;
- (f) replacing some more of the exchangeable tools on the work drum;
- (g) again driving the work drum with the drive motor via the drive line and thereby rotating the work drum at the first rotational speed;
- and
- (h) lowering the work drum back into engagement with the ground surface and working the ground surface, all of steps (a)-(h) occurring with the auxiliary drive operably mounted on the machine.
