NERM/ERM SERIES

ELECTRIC CHAIN HOISTS WITH
MOTORIZED TROLLEYS

The MR Series of electric trolleys further expand the capabilities of our NER/ER line of
electric hoists. These trolleys feature an innovative side guide roller system that results
in very smooth travel along the beam.

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 and trolleys. Hoist speed ratio is 6:1 with
adjustability up to 12:1. Trolley speed ratio is 6:1
with adjustability up to 10:1
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.
“The Guardian”: Smart Brake Technology
A current driven electromagnetic brake does not
release unless the motor is energized. 10 year hoist
brake warranty.
Contactors
Mechanically interlocked, heavy-duty contactors on
single speed models.
Pendant Controls
High Air Flow
Ergonomic design for operator comfort. Red button
emergency stop is standard on all 4-button pendants.
Cooler motor and brake attributed to an engineered
motor fin, fan blade and fan cover design.
Easy Access Suspension
Unique Load Sheave
External pins allow for quick change from hook to
lug for trolley mount configurations on most models.
Increased number of pockets reduce chain vibration and
increase chain life. 5 pockets standard; 6 pockets on
smaller body hoists.
High Strength, Corrosion and Wear
   Resistant Load Chain
Friction Clutch and Load Brake
Grade 80, super strength, nickel-plated load chain,
certified to DIN standards, uses unique technology
to greatly increase resistance to fatigue and wear.
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.

NER Dual Speed Electric Chain Hoists
Smart Limit Option

Our unique Smart Limit is available on NER three phase dual speed electric chain hoists. Unlike geared limit
switches, this Smart Limit allows the user to add upper and lower limit positions that can be conveniently
programmed at the pendant. The soft stop feature within the Smart Limit slows the hook down as it approaches
each limit for smooth and very precise load positioning.

*The NER/ER030LD listed is the previous hoist model (2 speed hoist & trolley via contactor control; trolley via VFD.
Consult us for VFD packages).
Specify hoist model and voltage. VFD Control is not reconnectable voltage.
Retrofit Smart Limit to existing NER Series hoist is not available.
Smart Limit can only be added to NER dual speed (VFD Control) units.
Infinitely Variable Speed - VFD Adder (Add to Dual Speed Prices)
• 2-Step infinitely variable - add $125.74 for each infinitely variable directional axis.
• 3-Step infinitely variable - add $440.10 for each infinitely variable directional axis.

(N)ER VFD HOIST CONTROL DESCRIPTIONS
Dual Speed Control
Uses a 2-step button and a VFD to control the speed. Pressing the button to the first step causes the hoist to
accelerate smoothly to the low speed. Pressing the button to the second step causes the hoist to accelerate
smoothly to the high speed. Releasing the button from the second step to the first step causes the hoist to
smoothly decelerate to the low speed. Releasing the button completely from any step causes the hoist to
decelerate quickly to a stop with the brake holding the load.
2–Step Infinitely Variable Control
Uses a 2-step button and a VFD to control the speed. The acceleration rate can be changed by changing
parameters in the VFD. The 2-Step Infinitely Variable differs from Dual Speed Control in that when releasing
the button from the second step to the first step it will maintain whatever the speed was at the instant before
the button arrived at the first step. This allows you to hold any speed between the low and the high speed.
If the hoist is operating at a speed that is less than high speed, and you wish it to operate at a faster speed,
press the button to the second step to accelerate the hoist. When you reach the desired speed, release the
button to the first step. Note that there is no deceleration function other than completely releasing the button.
3–Step Infinitely Variable Control
Uses a 3-step button and a VFD to control the speed. This control is similar to the 2-Step Infinitely Variable
Control with the added feature of a deceleration function. If the hoist is operating at a particular speed and
you wish it to operate at a faster speed, press the button to the third step to accelerate. When you reach the
desired speed, release the button to the second step to maintain that speed. If the hoist is operating at a particular
speed and you want it to operate at a slower speed, release the button to the first step to decelerate. When you
reach the desired speed, press the button to the second step to maintain that speed.
