standard and powered trolley 7700 and 7790 series link chain hoists continuous heavy-duty applications 7790 series 2200 and 4400 lb capacity 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 of standard lift and 6 feet of pendant or pull chain control 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 options continued spark resistant because of their operating characteristics air hoists are generally considered spark resistant standard 7700 and 7790 series hoists come with steel snaphooks 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 1 applications aro offers a variety of hoist options and accessories refer to the accessories page for additional information 7790 series specifications description rated capacity lbs control type suspension falls of chain lifting speed w/rated load variable from 1 to fpm lowering speed w/rated load variable from 1 to fpm air pressure psi air consumption at max rated load scfm air inlet size with 1800 swivel in recommended hose size in chain basket see chain basket chart in accessories load chain size link dia pitch weight of hoist lbs w/pull chain w/pendent power trolley performnce data beam type minimum-maximum beam height in standard minimum-maximum beam width in minimum turning radius ft traverse speed ft/min system weight lbs 7790a 2200 pull chain/pendent hook/trolley adapter 1 4-26 5-44 90 65-70 1/2 nptf 1/2 i.d canvas/metal .312 858 57 62 tapered/flat track 8-12 31/4-6 31 /2 70 110 7792a 4400 pull chain/pendent hook/trolley adapter 2 0-12 4-24 90 65-70 1/2 nptf 1/2 i.d canvas/meta .312 858 76 81 tapered/flat track 8-12 31/4-6 3 1/2 70 129 6 www.irhoist.com
