摘要： The present invention relates to a ground sawing machine comprising a frame supported by rear wheels (34a, 34b) and front wheels (36a, 36b) arranged for moving the ground sawing machine over a surface (38). At least one motor (40, 6) and a saw blade (2) are mounted to the frame, at least one motor (40) being arranged to propel the saw blade (2) to cut against the surface (38). The pointing direction (80) relative the surface (38) of the rear wheels (34a, 34b) and/or the front wheels (36a, 36b) is adjustable by means of an electrically controlled actuator (56) which is controlled by means of control means (70, 71, 72) arranged to provide at least three different control signals, one for left turn, one for right turn and one for center. The control signal for left turn and right turn are arranged for adjusting the pointing direction (80) of the adjustable wheels (34a, 34b) correspondingly, and the control signal for center is arranged for adjusting the pointing direction (80) of the adjustable wheels (34a, 34b) to a predetermined value.
摘要翻译： 本发明涉及一种地面锯切机，其包括由后轮（34a，34b）和前轮（36a，36b）支撑的框架，所述前轮（36a，36b）布置成用于将地面锯切机器移动到表面（38）上方。 至少一个马达（40,6）和锯条（2）被安装到框架，至少一个马达（40）被布置成推动锯条（2）以切割表面（38）。 相对于后轮（34a，34b）和/或前轮（36a，36b）的表面（38）的指向方向（80）可借助于电控制的致动器（56）进行调整，该电致动器通过 控制装置（70,71,72）被设置为提供至少三个不同的控制信号，一个用于左转，一个用于右转而一个用于中心。 用于左转和右转的控制信号被布置用于相应地调节可调节轮（34a，34b）的指向方向（80），并且用于中心的控制信号被布置用于调节可调节轮的指向方向（80） （34a，34b）变为预定值。

摘要： Control system for a remote-controlled working machine (10) provided with caterpillar tracks (6) or the like for the travel thereof, e.g. a demolition robot intended for demolition work, etc., the said control system including a remote control (11) intended to be carried by an operator situated beside the machine (10), the said remote control (11) being connected wirelessly, e.g. via Bluetooth, or by means of a cable to at least one electronic unit in the machine, and having at least one control stick or joystick (12, 13) and a number of buttons, levers and/or knobs for operating the different travel and working functions of the machine. The machine furthermore has one or more different setting modes or positions, wherein its control sticks and/or certain buttons have different functions in different modes. In a travel mode, also referred to as a transport position, travel of the machine is handled entirely by one control stick (12, 13), advantageously the left control stick (12), such that the caterpillar tracks (6) of the machine are operated as follows: - if the control stick is moved forwards or backwards, both caterpillar tracks (6) are driven forwards or backwards so that the machine moves forwards or backwards; - if the control stick is moved straight to the left, the right caterpillar track is driven forwards and the left caterpillar track is driven backwards so that the machine turns to the left; - if the control stick is moved straight to the right, the left caterpillar track (6) is driven forwards and the right caterpillar track is driven backwards so that the machine turns to the right. The operator's other hand is thus free for other tasks during travel of the machine.
