MANKATO, Minn. – Condux Tesmec 2-3 bundled conductor helicopter blocks are now available in 24- and 32-inch diameters, measured to the bottom of the groove. The one-piece cast aluminum frame is over 25% lighter, yet stronger and less likely to break compared to aluminum blocks with welded extruded frames.
The unit’s specially designed counter-weight fly-in gate allows for quicker and more secure rope installs, featuring a unique hinge for safer and more efficient cable removal during clipping operation. Specially designed polyurethane sectors for the 32-inch block are available for use with twisted pair, T2/VR2 conductor.
With a workload rating of 12,000 lbs, the Condux Tesmec 2-3 bundled conductor blocks are load tested to 60,000 lbs providing a 5:1 safety factor. Lightweight aluminum blocks are easier to handle and require less fuel when hanging by helicopter or shipping from jobsite to jobsite. Replaceable nylon sectors are also available.
