The Harrington LX lever hoist with hook mount is a compact, manually operated hoist featuring a die-cast aluminum body and steel frame for mobility, tight workspaces, and durability. Low headroom allows the hoist to fit in tight workspaces, a free-chain adjusting mechanism facilitates rapid adjustments, and a low pulling force requirement enables ease of use. The hook mount and load hook have notched tips to hold latches more firmly in place. In addition, a single-step reduction gear helps secure the load for added safety. The Weston-style brake is completely covered for protection from dirt, dust, and rain, and the grade 100 nickel-plated load chain is wear and corrosion resistant. The handle grip is made of rubber for comfort, while the load chain guide mechanism allows for smooth, quiet operation. The Harrington LX lever hoist is used primarily in transportation, construction, and plumbing applications to lift and move heavy loads in small spaces, and can be employed for similar purposes in other industries. This hoist is factory load tested to 125% of rated capacity in accordance with American National Standards Institute/American Society for Mechanical Engineers (ANSI/ASME) requirements. It also complies with ANSI/ASME B30.21 and ANSI/ASME HST-3M standards. When used according to manufacturer’s recommendations, this product is covered by a two-year warranty from date of shipment against defects in workmanship or materials.
Hoists are mechanical devices that use relatively small amounts of force to lift, lower, and move heavy loads. Manual hoists work by transferring a force exerted by hand across a series of gears that concentrate it into a force great enough to lift the designated load. The lifting mechanism consists of a pulley with a chain or cord and large wheel, or a ratchet lever attached to a large wheel; a drive shaft; gear set; sprocket wheel threaded with a load chain; and a lifting hook. The pulley or ratchet turns the drive shaft, which engages the gears; the gears interact to rotate the sprocket wheel and load chain, which pulls the hook up to lift the load. When the force used to turn the large wheel reaches the smaller sprocket wheel, it has become concentrated enough to lift the load. Friction disk brakes called Weston-style brakes are attached to the large wheel. These brakes hold the load in place while the operator’s hands are released to make the next pull, secure the load once it has been lifted, and control the descent of load as it is lowered. Hoists can be attached to structures such as cranes, ceilings, or walls by a variety of methods including hook, trolley, deck, base, wall, and ceiling mounts. They are used in a variety of industries including transportation, construction, manufacturing, mining, plumbing, foundry, and materials handling.
Capacity is the maximum rated load a hoist can handle. While manufacturers may indicate they have tested a hoist beyond its limits, operators should never attempt to lift a load heavier than the maximum rated load. Pull force describes the amount of force that needs to be applied to lift a load. If a 1/2 ton manual hoist specifies a pull force of 40 lbs., for example, the operator needs to be able to pull a 40 lb. weight in order to lift the maximum 1/2 ton (500 lb.) load. Headroom is the distance from the bottom of the load hook to the top of the hoist. This is the minimum amount of vertical space needed for the hoist to hang freely and operate correctly. Lift is the maximum vertical distance the load hook can move a load.
Harrington Hoists manufactures hoists and cranes. The company, founded in 1854 and headquartered in Manheim, PA, meets International Organization for Standardization (ISO) standard 9001.
