NER/ER Electric Chain Hoists
Forged Carbon Steel Hooks
Under excessive loads will open gradually
and not fracture. Ball bearings
produce smooth rotation.
Bottom hook will
swivel 360 degrees.
Heavy-duty hook
latches are standard.
Durable Push-Button Pendant
Easy to use, one-handed operation.
Rated IP65. Standard control voltage
is 110V. Strain relief wire is molded
to pendant cord for added support
and dependability.
Unique Chain Guide
Provides quiet and smooth guiding of chain.
Easily replaced without disassembly of hoist.
Heavy cast iron construction
for improved wear versus
stamped steel design
offered by many
manufacturers.
Extreme Duty Motor
Increased performance through 60 minute duty rating, H4 classification,
Class B insulation, cooling fins, and standard thermal motor protection.
Offers higher horsepower than most competitors.
External Motor Fan
Functions to quickly eliminate motor and brake heat. This
results in improved hoist duty rating and greatly lengthens
brake life. Motor is totally enclosed, fan cooled (TEFC).
Pull-Rotor Motor Brake
Extremely durable and
reliable, this advanced
design contains no
brake coil to fail like
conventional disc brakes.
Compact Aluminum Body
Die-cast body is lightweight
and offers low headroom—
one of the best in the industry.
Paint is electrostatically applied.

Superior
Quality Chain
Precision gauged,
Grade 80,
nickel-plated
load chain is heat
treated for wear
resistance and
extended life.
Single fall available
through 3 Ton.
Long Life Friction Clutch
Protects hoist from damage and prevents
overwinding. ER Series couples Weston-style
load brake with friction clutch.
Load Sheave
Deep-groove pockets fully support the load
chain during operation. Reduces vibration
and chain wear and provides a true vertical lift.
Completely Sealed Body
Suitable for both indoor and outdoor
applications, including harsh
environments. Gaskets throughout
the hoist provide for an IP55 rating.
Heat Treated Helical and Spur Gears
Precision machined for long life. Oil bath lubrication
results in a quiet, smooth, cool operation.
Count Hour Meter
This maintenance feature, supplied
as standard on the ER Series hoists,
tracks motor starts, running time and
usage history by instant digital display.
Meter operates independently of the hoist.
Easy Maintenance Control Panel
Simple layout of controls and a single
swing-out panel. Hinged controller
cover provides standard wiring diagram
and allows fast on-site access.
Plug-In Connections
Saves valuable time
on setup and
maintenance.
“Quick
disconnect”
replaces
typical
competitive
hard-wired
designs.
Operating
Conditions
Recommended
for –4° to +104°F
and humidity
of 85% or less.

NERM/ERM Electric Chain Hoists
With Motorized Trolleys
To further expand the capabilities of our NER/ER line of electric hoists, the MR Series
of electric trolleys was developed. They feature an innovative side guide roller
system that results in very smooth travel along the beam. Harrington’s MR trolley
provides the mobility needed in a wide variety of industrial applications.
Refer to pages 4, 5, 6 and 7 for features and benefits and page 8 for standard hoist specifications.
