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.
