NERM SERIES

ELECTRIC CHAIN HOISTS WITH
MOTORIZED TROLLEYS

The MR Series of electric trolleys further expand the capabilities of our NER line of electric
hoists. These trolleys feature an innovative side guide roller system that results in very
smooth travel along the beam.
Voltage (Power Supply) The Models shown on this page are 208/230/460 volts three phase.
For 115/230 volt single phase models click here:

FEATURES AND BENEFITS
UL® Listed Standard Count Hour Meter
Certified and listed to UL 1340 “Standard for Hoists.” 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.
Green Initiative
Built smarter without the use of harmful materials. Environmentally friendly. RoHS compliant.
Perpendicular Orientation
MR motorized trolley mount hoists are configured as
perpendicular to the beam. Parallel mount is
available as an option.
Notched Hook and Latch System
Provides positive closing and improves resistance
against lateral forces.
Dual Speed VFD
Limit Switches
Under-the-cover VFD standard for dual speed hoists.
Speed ratio is 6:1 with adjustability up to 12:1.
Low-profile upper and lower limit switches are
standard.
“The Guardian”: Smart Brake Technology
Extended Chain Life
A current driven electromagnetic brake does not
release unless the motor is energized. 10 year hoist
brake warranty.
Decreased chain wear as a result of a revolutionary heat
treatment process, improved material and chain size.
Contactors
Pendant Controls
Mechanically interlocked, heavy-duty contactors on
single speed models.
Ergonomic design for operator comfort. Red button
emergency stop is standard on all 2-button dual speed
pendants.
High Air Flow
Cooler motor and brake attributed to an engineered
motor fin, fan blade and fan cover design.
Easy Access Suspension
External pins allow for quick change from hook to
lug for trolley mount configurations on most models.
Unique Load Sheave
Increased number of pockets reduce chain vibration and
increase chain life. 5 pockets standard; 6 pockets on
smaller body hoists.
Friction Clutch and Load Brake
Friction clutch is standard on NERM models.
Carbon friction material provides consistent
performance over a wide temperature range.
