About Harrington ET525 Manual Push Trolley For Electric

The Harrington ET525 manual push trolley has a 525 lb. maximum capacity, has side plates and wheels made of steel for strength, and is suitable for use with a lug mount electric chain hoist. This hoist trolley fits I-beams with flange widths of 1.97 to 3.94 inches and a 23.6 inch minimum radius for curve. Hoists are devices that use relatively small amounts of force to lift, lower, and move heavy loads. Power hoists transfer a small, motor-generated force across a series of gears that multiply the force into one large enough to lift the designated load. Their lifting mechanisms consist of a motor; drive shaft and gear set; and a chain, rope, or wire, with a hook attached to it for lifting loads. Hoists are commonly suspended from structures by hook or trolley mounts, and are typically used in a variety of industries such as transportation, construction, manufacturing, mining, plumbing, foundry, and material handling. Load 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. Lifting speed describes, in feet per minute (fpm), how quickly the hoist can lift the maximum rated load. Lift is the maximum vertical distance the load hook can move a 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. Duty ratings describe the maximum amount of time a hoist can run and the number of times it can start over a given time period under various conditions such as intermittent use, or short and lengthy periods of operation. Harrington Hoists manufactures hoists and cranes. The company, founded in 1854 and headquartered in Manheim, PA, meets International Organization for Standardization (ISO) standard 9001.
