7700 SERIES HOISTS

LINK CHAIN (STANDARD AND POWER TROLLEY)


550 lb (250 kg) - 2200 lb (1000 kg) Capacity

CONTINUOUS HEAVY-DUTY APPLICATIONS

7700 Series Link Chain hoists have been designed specifically for heavy-duty industrial applications where loads vary between 1/4 and one metric ton. Simple, rugged, and reliable, these hoists are constructed with few moving parts, for easy repairs and less down time. 

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 LINK CHAIN 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.
  • Pendant or pull chain control responds immediately to operator's commands.
  • Brake control easily adjusts to meet specific load ranges.
  • Motor and gearing provides faster lift speeds with low air consumption.
  • Compared to roller chain, link chain lasts longer, handles heavier loads, and is better for high duty cycles.

7700 LINK 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.
