Harrington® NER003H-20 Electric Chain Hoist, 1-3/32 in Hook Opening, 500 lb Load, 20 ft Lift, 13-13/16 in Minimum Hook, 0.25 ton

Our NER/ER electric hoists are designed for peak performance -even on the toughest jobs in the toughest conditions. Quiet operation and minimal vibration lowers workplace noise pollution, helps reduce worker fatigue and extends the life of the hoist. The NER/ER's Guardian Smart Brake has an electrical fail-safe design that uses DC current to control brake activation. The fast activation drastically reduces wear on the brake discs, preserving the correct brake gap. The result is a maintenance-free braking system with a 10-year hoist brake warranty. Hoist performance is Increased through 60 minute duty rating, H4 classification, Class B insulation, cooling fins and standard thermal motor protection. This hoist offers higher horsepower than most competitors. Our NER/ER uses Harrington® world-class, super-strength chain. Its shorter and narrower link profile allows for greater surface area contact, giving it better wear resistance and overall tensile strength. External pins allow for a quick and easy change from hook to lug for trolley mount configurations on most models. Most models are certified and listed to UL 1340 “Standard for Hoists.” Our ER model has the same high-quality features as our NER hoist plus it has a secondary brake, our Weston-style mechanical load brake. The count hour meter records and displays the number of lowering starts and hoist on time which is valuable for preventive maintenance. This feature is integral to VFD on dual speed models. Harrington's dual speed models come with a standard "under-the-cover" variable frequency drive. This device works by varying the power to the motor, allowing you to adjust both the high and low speeds. The VFD also adds soft-start/soft-stop operation to reduce shock loads, swing and bounce, giving you more precise load control and increasing the life of the hoist. Harrington® offers a unique Smart Limit option on our NER three phase dual speed electric chain hoists. Unlike geared limit switches, this Smart Limit allows the user to add upper and lower limit positions that can be conveniently programmed at the pendant. The soft stop feature within the Smart Limit slows the hook down as it approaches each limit for smooth and very precise load positioning.
