Overview
Harrington’s EQ Series three-phase dual speed (VFD Control) electric chain hoists are ergonomically designed for easy installation and operation in mediumand heavy-duty industrial applications. These hoists have an extremely compact and lightweight body, and are perfect for any work station application. The EQ hoists include 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:
- 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 MachinedHelical 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 Owner’s 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.
