vMOTOR ERAKEWright rcclil ied D-C magnet-actuated disc brake has been proven inmi l l ions ot hours of in-serv ice operat ion. l t de l ivers rapid s tops wi thminimum to zero hook dritt. The motor brake assembly is seperatedfrom the gear housing for rapid cool ing. This mul t ip le co i l brake israted a min imum ot 150% ot lu l l load motor torque.Exclusive brake-sensing microswitch, standard on Work-Rated andWtight Ametican hoists, prevents molor from operating against theengaged brake. lt also prevents the motor from operating when brakerequires adjustment.

OVERLOAD CUTOFFExclusive palented Wright unit is standard on all Work-Rated andWtight-Way hoists except single line models. Protects load, hoist andoperator by in terrupt ing ra is ing c i rcu i t when hois t is over loaded. Theelect ro-mechanical device is designed to in terrupt the hois t l i f t ing c i rcuit if the load it senses exceeds the preset capacity of the cutoffdevice. When the l i f t ing c i rcu i t is in terrupted, the lower ing c i rcu i t re-mains in tact to a l low the load to be lowered and removed. When theover load is removed, the l i f t ing c i rcu i t is automat ica l ly restored.

MECHANICAL LOAD BRAKEAutomat ic Weston- type mul t ip le d isc brake can hold a tu l l capaci tyload independent of motor brake. This brake assures that load doesnot accelerate while being lowered. No wear compensation adjust-ment is reoui red.

MOTORStandard NEMA f lange, Class F Insulat ion, 3o-minute duty motor isprovided for standard commercial power supplies. The motor has astandard NEl t A shaf t extension.

DRUMThe large diameter steel drum has deep machined grooves and largef langes . A t leas t two fu l l tu rns o f rope remain on the drum a t thelowest hook position of rated l ift.

TROLLEY WHEELSOn the Wotk-Rated and Wright American hoists trolley wheels areforged steel with machined and hardened treads. On lhe Wright-Wayhoists wheels are cast iron with hardened treads. They come com-p le te w i th p re- lubr ica ted , sea led , heavy du ty ba l l bear ings .

H3General machine shop, fabricating, assembly, storage, and warehous.ing. Loads and uti l izat ion randomly distr ibuted. Total running t ime notover 25o/o of the work oeriod.

H4

Manual or automatic cycl ing operations of l ighter loads with ratedloads infrequently handled such as in heat treating and plat ing opera-t ions, with total running t ime frequently 50% of the work period.

H5Bulk hand l ing o f mater ia l in combina t ion w i th buckets , magnets , o rother heavy attachments. Equipment often cab operated. Duty cyclesapproaching continuous operation are frequently necessary. Usermust specify exact delai ls of operation, including weight ofattachments.

When ordering any tvtight hoist, the first place to start is its proper Acco product number. The productnumber is speci f ic for the tol lowing informat ion: capaci ty, headroom, reeving, suspension, l i f t , l i f t ingspeed, hoist control and motor horse power. For Wright-Way hoist it also specifies motor voltage (foiwork'Rated a d Wtight Ametican hoists the motor voltage must be supplied along with the hoiat pro.duct number).Product numbers lo( Wrightway hoists are found in "Wright Hoists" Bulletin No. PD-2000. l,y/grlAmerican product numbers are found in "Wright American Electr ic Wire Rope Hoists" Bul let in No.PD-2010.

Glossary of Terms

ACM (Accelerat ion Control Module) A sol id state electronic control that providesgentle accelerat ion and decelerat ion of a hoist trol ley or crane throughout the en.t ire operation cycle. ACM minimizes load pendulum swing more eff iciently thanballast resistors or f luid coupling by control l ing accelerat ion up to 5 seconds afterstart while providing ful l motor voltage for the whole cycle.AGMA American Gear Manutacturers Associat ionANSI American National Standard lnst i tuteBallast Resistors Inserted in the power l ines to an induction motor, bal lastresistors control trol ley accelerat ion for smoother starts by reducing the voltagewhile start ing; in turn reducing torque; increasing the motor accelerat ion t ime,al lowing the motor to come to speed smoothly. Bal last resistors are f ield ad-justable.

CMAA Crane Manufacturers Associat ion of AmericaEnd Approach The minimum distance that a hoist can travel to the end of a cranebridge or track without impacting a wall or some other obstruction. Crossmounted hoists have a lower minimum end approach than standard paral lelmounted hoists.Explosion Prool The property of an enclosure to contain internal sparking withoutcausing external hazard. Explosion proof hoists are used in operating en-vironments where f lammable gases are present.

FPM (Feet per minute) The standard measurement of hoist l i t t ing speed, trol leytravel and crane bridge travel.Headroom The distance from the bottom of the beam or monorai l on which thehoist travels to the bearing point of the load hook when the hook is raised to i tshighest posit ion. On a top running hoist, i t is the distance from the operating treadof the trol ley wheels to the hook high posit ion.
