Telescoping mast assembly with safety latch system
A safety latch telescoping mast system for a portable light tower having a towable trailer having a frame and an engine driven electrical generator and a light assembly for attachment to the uppermost end of a telescoping mast member, which includes a pivotable spring loaded safety latch assembly positioned to remain in a first, cocked, position wherein an idler roller is in rotational engagement with a hoisting cable and the latch is outside the opening in the stationary mast member when the first hoisting cable is under tension, which trips to a second, position wherein the latch passes through the opening in the stationary mast member and engages into a slot in the first telescoping mast member when the tension on the first hoisting cable is relieved.
