| 摘要 |
<p>The invention relates to a device for monitoring the safety of an articulated mast ( 22 ), especially of a concrete distribution mast, whose mast segments ( 23 to 27 ) are controlled via a remote control ( 50 ) and a control device ( 62 ) that is responsive to the remote control signals using a computer-assisted circuit arrangement ( 80 ). Safety monitoring is made possible by the provision of an interrupter element ( 112, 112 ') in the control device ( 62 ) which disrupts, via a delay member ( 116 ), the connection to the control inputs of the actuators ( 92, 94 ) associated drive units and/or the feed units ( 98, 100 ) for the purpose of power or pressured oil feed once the remote control elements ( 52 ) of the remote control device ( 50 ) are in the off-position.</p> |
