A lighting winch in which the lighting barrel (2) is suspended by cables (4) from a cradle (8) which, in the event of the winch being overloaded pivots to actuate a switch to prevent operation of the winch motor (13). The winch also incorporates a respective slack cable detector (83) for each cable which, when actuated, also prevents operation of the winch motor. The winch may be of the self-climbing type (Fig. 9) in which the motor is carried with the lighting barrel. <IMAGE> |
