The Greenlee 441-3-1/2 feeding sheave is a top - notch solution for cable installation in 3 - 1/2 inch conduits. It has a weight of 17 lbs (7.7 kg), making it manageable for various work scenarios. When it comes to the capacity based on the angle of pull, it shows great performance. At a 15° angle, it can handle 6500 lbs (28.9 kN), and as the angle increases, it still maintains decent load - bearing capacity, like at 90° with 2500 lbs (11.1 kN). This sheave comes with some excellent features. Its yoke frame easily slides into the end of the conduit and holds the sheave firmly. This design allows the cable being fed into the conduit to roll smoothly over the sheave, reducing friction and ensuring a seamless installation process. The 5' (127 mm) wide aluminum alloy sheave is equipped with self - lubricating bearings, which not only extend the product's lifespan but also enhance its efficiency. Additionally, the split tube feature enables easy removal after the cable is installed, saving you time and effort.
Using the Greenlee 441 - 3 - 1/2 feeding sheave is a breeze. First, slide the yoke frame into the end of the 3 - 1/2 inch conduit. Make sure it fits securely. Then, start feeding the cable over the sheave. You'll notice how smoothly it rolls, thanks to the self - lubricating bearings. When you're done with the cable installation, simply take advantage of the split tube design to remove the sheave easily. As for maintenance, keep it clean from dirt and debris. Periodically check the self - lubricating bearings to ensure they're working properly. Avoid overloading the sheave beyond its specified capacity at different angles of pull. This will help you get the most out of your product and ensure it lasts a long time.
