摘要
A high-level lighting tower has a generally ring-shaped illuminating lamp or floodlight supporting carriage device operatively supported from a tower head and releasable therefrom to be lowered by a winch-controlled cable system providing a multi-point carriage suspension. Lowering of the carriage to or adjacent to ground level is enabled. Individual adjustments of the carriage cables is provided for. Special adaptability for multi-leg generally tapering towers is afforded. An electricity supply and electrical control system for the lights has not only electrical connection signalling means but also over-load safety means. An attention-getting device such as a beacon light may advantageously be mounted upon a peak provided by juncture of sloping supporting head arms.
