The Harrington ED dual adjustable electric chain hoist with hook mount has an ergonomic one-handed cylinder for greater load control, a single phase motor for 120-volt outlets, and a die-cast aluminum body with low headroom for tight workspaces and mobility. This hoist has a touch rocker switch above the handgrip to facilitate switching between low and high speed, and a finger turn knob that enables custom speed settings from 0 to 100 percent. The Harrington ED dual adjustable electric chain hoist has a dual-brake system with a Weston-style mechanical load brake and an electric regenerative brake, which generates electricity to help power the motor. An upper limit switch helps prevent over winding and over lifting. The load hook is removable, allowing operators to use a variety of below-the-hook material handling devices. This hoist includes a small direct current (DC) motor rectifier that converts alternating current (AC) to DC to reduce weight, generate less heat, and help maximize duty ratings (maximum run time and number of starts the hoist can perform in a given time period). The Harrington ED dual adjustable electric chain hoist is typically used to lift and move loads for industrial or commercial applications, but also may be used in residential workshops. This hoist is built in compliance with American National Standards Institute/National Fire Protection Association (ANSI/NFPA) 70, National Electrical Code. When used according to manufacturer’s recommendations, this product is covered by a one-year warranty from date of shipment against defects in workmanship or materials.

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.
