(INVERTER FOR SMOOTH TRANSITIONAL SPEED) |
|
The
dual speed inverter delivers smoother movement than contactor control which
reduces load swing. The inverter
can be programmed to operate specific to the application, resulting in smooth
starts, improved control, improved
positioning accuracy and overall increased productivity. Standard lifting
speed ratio is 6:1. Standard traversing
speed ratio is 6:1 adjustable to 10:1.
A no-load high-speed function is a standard feature, allowing its hoisting
speed to move 1.3 times faster during no-
load operation. When the no-load condition is detected by the inverter,
this function is activated automatically
switching to high-speed operation, leading to improved work efficiency with
ease and safety. The function is easily
activated (ON/OFF) with the push button control.
EQ, EQM and SEQ inverter units are well-customized for lifting/traversing
applications including exclusive software,
and are also provided with measures against impact and heat, which were
verified through long-run tests. |

SEQ
Series single-phase dual speed (VFD Control) electric chain hoists are designed
for
easy installation and operation in medium- and heavy-duty industrial applications.
These
hoists have an extremely compact and lightweight body and are perfect for
any work station
application. The SEQ hoist includes a no-load high-speed function that automatically
increases hoist speed up to 130 percent when the load is less than 30 percent
of working
load limit. |

Features
and Benefits |
|
Pull-Rotor
Motor Brake - Extremely durable and reliable, this advanced design contains
no brake coil to fail like
conventional disc brakes.
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).
Precision Machined Helical Gears - Immersed in oil bath lubrication
results in quiet, smooth and cool operation.
Chain Container - Durable plastic containers are standard.
Corrosion Resistant Load Chain - Nickel-plated, Grade 80, DIN chain
for superb durability and strength.
Forged Carbon Steel Hooks - Under excessive loads will open gradually
and not fracture. Ball bearings produce
smooth rotation. Bottom hook will swivel 360°. Heavy-duty hook latches
are standard.
Optional Suspension Bar - For low headroom or enclosed track trolley
applications. Easily changed from top hook
to suspension bar.
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
Owners Manual for details.) Gaskets throughout the hoist provide for
an IP55 rating.
Variable Frequency Drive (VFD) - Dual speed controls via under-the-cover
variable frequency drive for both
single-phase and three-phase hoists. VFD includes count hour meter, load
limiter and no-load high-speed function.
Long Life Friction Clutch - Protects hoist from damage and prevents
overwinding.
Upper/Lower Limit Switch - Low profile upper and lower limit switches
provide excellent headroom.
Unique Chain Guide - Provides quiet and smooth guiding of chain.
Heavy cast iron construction for improved wear
versus stamped steel design offered by many manufacturers.
Durable Push Button Pendant - Easy-to-use, one-handed operation.
Rated IP65. Standard control voltage is 24V.
Strain relief wire is molded to pendant cord for added support and dependability.
E-Stop is standard on all pendants.
Extreme Duty Motor - Increased performance through 30/10-minute duty
rating, H4 classification, Class B insulation,
cooling fins and external thermal motor protection.
Load Sheave - Five deep-groove pockets fully support the load chain
during operation. Reduces vibration and chain
wear. Provides true vertical lift.
Operating Conditions - Recommended for -4° to +104°F and
humidity of 85% or less. |

HOIST CONTROL DESCRIPTIONS |
|
The
dual speed inverter delivers smoother movement than contactor control which
reduces load swing. The inverter
can be programmed to operate specific to the application, resulting in smooth
starts, improved control, improved
positioning accuracy and overall increased productivity. Standard lifting
speed ratio is 6:1. Standard traversing
speed ratio is 6:1 adjustable to 10:1. |
|
A
no-load high-speed function is a standard feature, allowing its hoisting
speed to move 1.3 times faster during no-
load operation. When the no-load condition is detected by the inverter,
this function is activated automatically
switching to high-speed operation, leading to improved work efficiency with
ease and safety. The function is
easily activated (ON/OFF) with the push button control. |
|
EQ,
EQM and SEQ inverter units are well-customized for lifting/traversing applications
including exclusive
software, and are also provided with measures against impact and heat, which
were verified through long-run tests. |
|

|

|
|
The
grade symbols are identical to those of ASME HST-1M. (Performance standard
for Electric Chain Hoist) |
