Who Needs This Product

The MightyLite+ covers the vertical jobs shorter SRLs cannot: towers, shafts, silos, and high bays where the worker travels far below a fixed overhead anchor. It is light enough to carry to the mount point and engineered to live there permanently, with labeling that still reads after years of sun.

Features

Long-Reach Lengths

Stocked at 20, 30, and 130 ft, with the 130 ft unit covering full-height tower and shaft work from one anchor.

Quick-Activating Inertia Brakes

The brakes engage in inches, limiting free fall to under 2 ft anywhere in the travel.

Lightweight Corrosion-Proof Housing

Aluminum and stainless construction keeps a big unit carryable and durable outdoors.

UV-Resistant Labeling

Scratch-resistant, fade-resistant graphics keep capacity and inspection data legible for years.

Permanent or Portable

Easy to carry and install overhead for the day, or mount permanently at a recurring access point.

Galvanized Steel Cable

The cable takes the abrasion of long vertical runs against structure.

⚠

Long cable, long swing. The farther the worker moves from vertical under the anchor, the bigger the swing fall. Keep travel inside the working cone in the manual and check the load-indicating hook before every use.
