Detail
HarringtonÂ’s EQ dual speed VFD 3-phase electric chain hoists are designed for medium to heavy-duty industrial and workstation applications. These hoists include a unique no-load high-speed function that automatically increases hoist speed up to 130% when the load is less than 30% 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)
Precisions 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 degrees. 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 OwnerÂ’s manual for details.) Gaskets throughout the hoist provide for an IP55 rating.
Variable Frequency Drive (VFD):
Dual speed controls vis “under-the- cover” variable frequency drive for both single-phase and three-phase hoist. VFD includes count hour meter, load limiter and no-load high-speed function. Long life friction clutch protects hoist from damage and prevents over winding.
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 manufactures.
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.
Conditions:
Recommended for -4 degrees to +104 degrees F and humidity of 85% or less.
