The control facility includes a control unit (10) which regulates operating elements (12,14,16), control devices (28,32,36) and control for a hoisting system (46) for auxiliary devices. An automatic switch (18) works independently from the other operating elements and is manually used to activate an automatic operational mode. Sensors (24,52) indicating operating speed and hoisting system position are connected electrically to the automatic switch, and enable auxiliary devices to be operated according to preset programmes, dependent on the speed and hoist position. The automatic mode can be overridden manually and supervisory and alarm functions are included (26,30,34,38). |
