7740B Series Link Chain Hoists |
| |
The
7740B air chain hoist has been engineered for production and utility
applications for loads up to 300 lbs.
Incredibly light, compact and portable, these hoists have been designed
so that they can be moved between workstations to perform various
lift operations. Requiring only 28 scfm of air flow, the 7740B will
operate from compressors as small as 3 horsepower.
Key features:
• Light weight and compact design
for ease of movement to different work locations.
• Rotary
vane air motor.
• Self-adjusting brake holds loads securely.
• May be operated between 60 and 100 psi.
• Pull chain
control provides accurate spotting control.
• Standard lift
is 10 feet; additional lifts are available.
• Standard pull
chain length is 6 feet or 4 feet less than lift.
• Steel
snap hooks.
• Hook or eye bolt mounted available. |

7700 and 7790 Series Link Chain Hoists
- Standard and Power Trolley
|
| |
7700
Series Link Chain hoists have been designed
specifically for heavy-duty industrial applications where loads vary
between 275 lbs. and 2200 lbs. Simple, rugged, and reliable, these
hoists are constructed with few moving parts, for easy repairs and
less down time.
|
|
|
| |
Key features:
• Exceptional
slow-speed control provides superior spotting characteristics and
ability to confidently "inch" loads into position.
•
Ideal for high duty cycles and when operating loads are near maximum
capacity.
• Powerful, self-cooling rotary motors keep ARO
hoists at peak performance in high temperature situations.
|
7790 Series Link Chain hoists are ARO's
most powerful units. The larger motor and increased horsepower provide
greater operational speeds and productivity in the one ton single-fall
and two ton double-fall ranges. A key advantage of single-fall operation
is that both longer lifts and chain storage become easier to manage.
Built with the same high-quality construction as the 7700 Series,
these hoists also require fewer repairs with less down time.
|
Key features:
• Larger motor and gearing provides
increased horsepower for faster lift speeds.
• Larger link
chain – 5/16" diameter compared to 1/4" diameter on
7700 hoists, accommodates larger loads with longer chain life.
• Headroom advantage in one ton capacities:
– 2 13/16"
advantage over hook mounted 7700 models.
– 6 13/16"
advantage over manual trolley 7700 models.
– 4 1/2"
advantage over power trolley 7700 models.
• Pull chain or
pendant control provides superior spotting characteristics and the
ability to confidently "inch" loads into position.

7700 and 7790 Series Link Chain Hoists -
Spark Resistant
|
| |
7700 and 7790 Series Spark Resistant Hoists are designed for Division
1 applications where, under normal operating conditions, the atmosphere
contains hazardous concentrations of flammable gases, dust, or other
materials.
Specifically engineered for continuous heavy-duty industrial applications
– between 400 lbs and 1500 lbs – ARO 7700 Series Spark
Resistant Hoists are available with bronze top hook or trolley adapter
suspension.
|
|
|
| |
Spark Resistant Features:
•
Stainless steel load chain and solid bronze hooks to prevent accidental
sparking.
• Pendant control handles, when ordered, are covered
with an industrial-grade vinyl grip. Pull chain controls come standard
with zinc-plated pull chain.
• Hoist capacities are reduced
and speed adjustments are locked into place to maximize chain life.
• Trolley models are supplied with bronze wheels.
