Lowering headframe masts allow the headframe to be lowered with a winch and are ideal for accessing headframes at ground-level when space around the mast is tight. These lowering headframe masts provide easy maintenance access at mast base and offer additional features such as optional headframe latching.Benefits include reducing risks of multiple internal cable-snagging problems by using a single multi-core electrical cable system for up to 12 floodlights.

High masts can be manufactured as single-direction, two-direction and circular multi-directional types according to floodlight orientation, depending on the customer’s requirements.
