400 lb (182 kg) - 1600 lb (727 kg) Capacity
CONTINUOUS HEAVY-DUTY APPLICATIONS
|
7700 Series Roller Chain hoists have been designed
specifically for heavy-duty industrial applications where loads vary between 400
lbs (182 kg) and 1,600 lbs (727kg). Roller chain models are recommended when
ultra-smooth lifting or pin point spotting is required. Roller chain is not
recommended for operations with high duty cycles or side loading requirements. Simple, rugged, and reliable, these hoists are constructed
with few moving parts, for easy repairs and less down time. Load capacities for
7700 Series hoists with roller chain have been reduced due to specific
load-bearing chain characteristics.
7700 Series hoists come complete with 10 feet
(3m) of standard lift and either 6 feet (1.8m) of pendant control or 5 feet
(1.5m) of pull chain control.
7700 ROLLER CHAIN FEATURES:
- Exceptional slow-speed control provides
superior spotting characteristics and ability to confidently
"inch" loads into position.
- Powerful, self-cooling rotary motors keep ARO
hoists at peak performance in high temperature situations.
- Motor and gearing provide fast lift speeds and
low air consumption.
- Responsive controls - pendant or pull chain -
react immediately to operator's commands.
- Roller chain hoists make ideal drive motors
with a continuous loop of roller chain. ARO "hoist rated" roller
chain size: 0.400"/0.625" (diameter/pitch).

7700 ROLLER CHAIN OPTIONS
|
SUSPENSION
- 7700 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 7700 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.
