Product Details
The NER Dual Speed series of electric chain hoists from Harrington features an under the cover variable frequency drive, providing exceptional load control and field-adjustable two speeds with up to a 12:1 speed ratio. Key features include "The Guardian" smart brake technology, a current-driven electromagnetic brake that remains engaged unless the motor is energized, a grade 80 nickel-plated load chain, and a variable frequency drive that allows for speed adjustability and includes integral hour counting functionality to record and display the number of lowering starts and hoist on time. Additionally, the hoists possess a 5-pocket load sheave designed to reduce 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 in accordance with RoHS requirements, and exceed the ASME H4 duty rating. Each hoist comes with a test certificate verifying that it has been factory load tested to 125% of its rated capacity, in compliance with ASME B30.16.
