Harrington SEQM010SD-SD-20 User Manual

EQ/SEQ Electric Chain Hoists

Simple
Construction

Low maintenance due
to no transformer,
no magnetic contactor,
no brake contactor and
no brake coil.

Unique Load Sheave

Increased number of pockets
reduces chain vibration and
increases chain life. Five
pockets standard.

4

Optional
Suspension Bar

External connecting
shaft allows for quick
change from hook
mount to suspension
bar mount.

No-Load
High-Speed

Hoist speeds 1.3 times
faster when working
with less than 30% of
full load.

Limit Switches

Low-profile upper and
lower limit switches
are standard.

Dual Speed VFD

“Under-the-cover” VFD
standard. Speed ratio
is 6:1.

Unique
Chain Guide

Provides quiet and
smooth guiding of
chain. Heavy cast
iron construction.

Standard Count
Hour Meter

Records and displays
the number of lifting/
lowering starts
and hoist on time
which is valuable
for preventive
maintenance. Integral
to VFD.

the beam.

Certified

CSA listed to:
UL 508, UL 508A, UL 1004
CSA Std. C22.2 No 33-M1984 (R2004)
CSA Std. C22.2 No 14-13

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.

5

Friction Clutch

Friction clutch is standard
on EQ/SEQ models.
Provides consistent
performance over a
wide temperature range.

Pull-Rotor
Motor Brake

Extremely durable and
reliable, this advanced
design contains no
brake coil to fail like
conventional disc
brakes. 5-year hoist

brake warranty.

High Air Flow

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

Pendant Controls

Ergonomic design for
operator comfort. Red
button emergency
stop is standard on
all pendants.

EQ/SEQ Electric Chain Hoists

Compact Aluminum Body

Die-cast body is lightweight and offers low headroom – one
of the best in the industry. Paint is electrostatically applied.

Completely Sealed Body

Suitable for both indoor and outdoor applications, including
harsh environments. (Consult Owner’s Manual for details.)
Gaskets throughout the hoist provide for an IP55 rating.

Pull-Rotor Motor Brake

Extremely durable and
reliable, this advanced
design contains no
brake coil to fail like
conventional disc brakes.

Optional
Suspension Bar

For low headroom or
enclosed track trolley
applications. Easily
changed from top
hook to suspension bar.

6

External Motor Fan

Functions to quickly eliminate resistor,

motor and brake heat. This results
in improved hoist duty rating and

greatly lengthens brake life. Motor is

totally enclosed, fan cooled (TEFC).

Extreme Duty Motor

Increased performance through 30/10-minute
duty rating, H4 classification, Class B
insulation, cooling fins and external thermal
motor protection.

Chain Container

Durable plastic containers
are standard.

Corrosion Resistant
Load Chain

Nickel-plated, Grade 80, DIN
chain for superb durability
and strength.

Heavy-duty hook latches are standard.

Forged Carbon Steel Hooks

Under excessive loads will open

gradually and not fracture. Ball

bearings produce smooth rotation.

Bottom hook will swivel 360 degrees.
