Description: The lever hoists are outfitted with a load holding weather proof Weston Brake, an the gears are protected from contamination and debris. Given the many benefits of synthetic slings, it's easy to see why they're such a well-loved rigging and lifting choice. Unless the object is properly centered, it may swing off-balance and crash into people or property nearby. All of these applications require a slow and steady movement of equipment of components with ease. Lever hoists are designed to operate in tight spaces and low headroom. These special grades of alloy steel chain are ideal for overhead lifting due to their high strength and abrasion resistance, as well as their ability to stretch up to 20% before breaking when subjected to overloading. A load limiter on a hoist is going to ensure that an operator does not overload the hoist by attempting to lift more that the rated capacity of the hoist. When you pull down on the chain that is wound around the lifting gear, then the chain hoist will lower the load. Red button emergency stop is standard on all 2-button dual speed pendants. The Twin-Path® patented design provides the rigger with two connections between the hook and the load for redundant back-up protection.
