Abstract (en)
[origin: EP0504867A1] In a computer-controlled system for lifting loads, particularly for stages and multi-purpose halls comprising - at least two independently controllable hoists (4a, 4b), - a control computer (1) for individually monitoring the system and controlling the individual hoists, which carries out an actual/nominal value comparison, - an operating terminal (5), - an operating computer (6) for administering the operating terminal (5) and transmitting travel commands to the control computer (1), - a network (2) for connecting control computer (1), operating computer (6), operating terminal (5) and the individual hoists (4a, 4b), it is provided according to the invention that - the network (2) is a ring network and that - the control computer (1) has a multi-channel structure with at least two channels (1a, 1b) and independently carries out the actual/nominal value comparison in each channel (1a, 1b) as well as alternately a monitoring of each channel (1a, 1b) by the other one (1b, 1a) and, when safety-relevant deviations are detected, stops the system for lifting loads via switch-off lines, which are designed to have at least two channels, the actual/nominal value comparison including at least a detection of the position and of the state of movement of the individual systems for lifting loads (4a, 4b, ...), a weight sensing, a monitoring for slack chains and a monitoring for the synchronous running of hoists (4a, 4b, ...) connected in a group. <IMAGE>
