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 a speed ratio of up to 12:1. Key attributes include "The Guardian," a smart brake technology that utilizes a current-driven electromagnetic brake, which only releases when the motor is energized. The hoists come with a grade 80 nickel plated load chain, 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. Additional features consist of a five-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. These hoists are UL listed to UL 1340, environmentally friendly meeting RoHS requirements, and exceed the ASME H4 duty rating. Each hoist includes a test certificate confirming that it has been factory load tested to 125% of its rated capacity, in accordance with ASME B30.16.
