The Greenlee 441-5 feeding sheave is a top - notch tool for conduit cable installation. It has a weight of 26 lbs (11.8 kg), making it sturdy and reliable. When it comes to the capacity based on the angle of pull, it performs impressively. At 15°, 30°, and 45°, it can handle 6500 lbs (28.9 kN). At 60°, it can manage 6000 lbs (26.6 kN), at 75° it takes 5500 lbs (24.4 kN), and at 90° it supports 5250 lbs (23.3 kN). This sheave features a yoke frame that smoothly slides into the conduit end and holds the sheave firmly. This allows the cable being fed into the conduit to roll over the sheave without a hitch. The 5' (127 mm) wide aluminum alloy sheave comes with self - lubricating bearings, ensuring long - lasting performance with minimal maintenance. Additionally, the split tube design makes it incredibly easy to remove after the cable is installed.
Using the Greenlee 441 - 5 feeding sheave is a breeze. First, slide the yoke frame into the end of the conduit. Then, start feeding the cable, and it will roll smoothly over the sheave. When it comes to capacity, always make sure the weight of the cable you're pulling matches the angle - based capacity we've provided. Don't try to pull a heavier load than the sheave can handle, as this could damage the tool and pose a safety risk. For maintenance, since the sheave has self - lubricating bearings, you don't need to do much. But it's a good idea to check the sheave and yoke frame regularly for any signs of wear or damage. If you notice any issues, stop using the tool and get it inspected or repaired.
