Features and Benefits
UL® Listed (Most models shipped with UL® listing.)
Certified and listed to UL® 1340 "Standard for Hoists."

Green Initiative
Built smarter without the use of harmful materials. Environmentally friendly. RoHS compliant.

Heavy-Duty Hook Latches
Standard.

Limit Switches
Low-profile upper and lower limit switches are standard.

Extended Chain Life
Decreased chain wear as a result of a revolutionary heat treatment process, improved material and chain size.

Contactors
Mechanically interlocked, heavy-duty contactors on single speed models.

High Air Flow
Cooler motor and brake attributed to an engineered motor fin, fan blade and fan cover design.

Unique Load Sheave
Increased number of pockets reduce chain vibration and increase chain life. 5 pockets standard.

Friction Clutch and Load Brake
Friction clutch is standard on NER/ER models and friction clutch with mechanical load brake standard on ER models. Carbon friction material provides consistent performance over a wide temperature range.

Standard 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.

High Strength, Corrosion and Wear Resistant Load Chain
Grade 80, super strength, nickel-plated load chain, certified to DIN standards, uses unique technology to greatly increase resistance to fatigue and wear.

Dual Speed VFD
Under-the-cover VFD standard for dual speed hoists. Speed ratio is 3:1 with adjustability up to 12:1.

"The Guardian": Smart Brake Technology
A current driven electromagnetic brake does not release unless the motor is energized. 10 year hoist brake warranty.

Pendant Controls
Ergonomic design for operator comfort. Red button emergency stop is standard on all 2-button dual speed pendants.



Note
NER vs. ER Features
ER model has same high-quality features as NER plus the following:
  • Second brake - Weston-style mechanical load brake.
Image shown with optional canvas chain containers.

For Lifting Motor: Although both 208/230 & 460 Volts are shown together, the motors are NOT reconnectable.
