Product Details
The NER Dual Speed series of electric chain hoists from Harrington features an under the cover variable frequency drive that provides exceptional load control and field-adjustable two speeds with up to a 12:1 speed ratio. Key attributes include "The Guardian" smart brake technology, which utilizes a current-driven electromagnetic brake that remains engaged unless the motor is energized. The hoists are equipped with grade 80 nickel-plated load chain, a variable frequency drive for speed adjustability, and integral hour count functionality that records and displays the number of lowering starts and hoist on time. Additionally, the design includes a 5-pocket load sheave to minimize vibration and extend chain life, a cooler motor and brake due to the fan-cooled motor, low-profile upper and lower limit switches, and plug-in pendant and power supply cords. The hoists are UL listed to UL 1340, built to be environmentally friendly meeting RoHS requirements, and exceed the ASME H4 duty rating. Each hoist comes with a test certificate confirming that it has been factory load tested to 125% of its rated capacity, in accordance with ASME B30.16.
