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’s 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.
Harrington’s dual speed NER/ER hoists 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.
The count hour meter records and displays the number of lowering starts and hoist on time which is valuable for preventive maintenance. Integral to VFD on dual speed models.
Most models are certified and listed to UL 1340 “Standard for Hoists.”
