Electric hoists are a mechanical unit that is designed to lift, lower or pull loads. Whether a manually-powered product for small loads or a heavy duty electrical motor driven version, an electric hoist can offer a load carrying capacity for companies and individuals, which no human alone could match. Electric hoists can be operated by electrical, manual, hydraulic or pneumatic power, but the most commonly used are electric hoists. Electric hoists are powered by an electrical motor that helps them lift or lower a load to a designated location. These types of electric hoists are typically mounted in one of three arrangements: lug, trolley or suspension mountings. For consumers who desire something besides off-the-shelf mounts, many companies additionally offer custom mounting configurations.
