CONTINUOUS HEAVY-DUTY APPLICATIONS
|
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.
7790 Series hoists come complete with 10 feet
(3m) of standard lift and 6 feet (1.8m) of pendant control.
7790 LINK CHAIN 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:
- - 2 113/16" 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.

7790 LINK CHAIN OPTIONS
|
SUSPENSION
- 7790 Series hoists are available with a
variety of suspension options - hook types, manual trolleys and power
trolleys to meet the needs of any operation. For added operator safety,
power trolley traverse speeds are set to gradually increase and decrease to
ensure safe load control with minimal load sway.
CONTROL
- ARO hoists are available with two easy-to-use
control options - pressure pendant or pull chain control. Both systems
provide the operator with total hoist control and the ability to confidently
inch loads into place. Pendant controls, when ordered with power trolley
systems, control both hoist operation and trolley movement.
SPARK RESISTANT
- Because of their operating characteristics,
air hoists are generally considered spark resistant. Standard 7790 Series
hoists come with steel snap-hooks and load chain and are regarded as safe
for Division 2 applications. Spark resistant models offer even more
protection in the form of stainless steel link load chain and bronze
snap-hooks, and are the only ARO hoists suitable for Division I applications
. ARO offers a variety of hoist options and accessories.
