SECTION I - GENERAL DESCRIPTION

H . GENERAL These CM AlRSTAR & All HoisIS are pre­c'Soon built chain Iype hoislS whK:t1ate buill in thfHcap'c­it)' SIZes: 1. 2 . and 3 Ion. AI model' use coil type load d'IaJn and have penclanllhronle conltols. Thefe are model varia· lions wllh hook or lug Iype suspensions. Hoists are also proviOed In sparll resrSlant modeb and corrosion res~lanl model'. (Nole: Sparll resiSlant models have capacity ral' Ings lower than standard models.)

1-2. BASIC CONSTRUCTION. All SiZes and model. 01 these CM AIRSTAR 6 Air HoislS are of lhe same basic: design, having many oommon and inl8fChanpeable pans. They con­srst pnmanIy of an aIurTw1um alloy flame and gearc.as.e COV8f

whd1 houses an alllomalic load !)rake and gN/' tram. An Ill/' moIor is mounled on the rear 01 the frame. An uwew hook or lug bnw:kel for suspending lhe hoisl is altached to the lop oIlheframe. An alloysleel coil load chIIln With lower block assembly is employed 10 rarse and lower loads. Up­per afld lower lImits of hook Iravel Ire limited by chain mounled limit aClualOl'$. Hoist operatIon Is controlled by a pendanlthrottle con trol assembly.

1·3. DIFFERENCES BETWEEN MODELS AND SIZES. The main dillerences between hoist mocIels are In lhe reeving 01 the 1000d c hain and the suspension employed. These ate described In Paragraphs a and b, below.

a. On Stilndard t ton capacIty holliS, the load chain is single rfleYed (one part 01 chain): on standard 2 Ion c.aPICllles, lhe cham Is double reeved (IWO parts 01 chaln~ on Slandard3loncapaclties, the chaIn is triple reeved (Ihree parts 01 chain). CoIl type chain Is fu ll. Ue~lng. electric welded, Unk chain: carburlzed steel on standard and corrosion flsis tant models and stain· lass steel on spark resistant models. Both types are especlatl~designed lor use In nolsl lng afld have spe· clal calibrated pitch. (HOle: On corrosion resIstant mooels. the load chain Is zinc plated.)

b. Suspension differences include a convenlJOnlI hook type mcx."Itll'lg and a lug type mounltng. Hook sus­perIIIOO allows portabitity pemtitung hotsiiO be eas­ily moved from JOb to joO. Lug susplnSlOl'l permits holst to be ngodIy mounled to overhead structure or attached 10 CM Rigid Mount Trolleys, affording un­''Sual headroom advantage.

1-4. OVERLOAD CLUTCH. eM AIRSTAR 6 Air Hoists are eqUIPped WIth an overload clutch that Is designed to help guurd against e~cessive overloads. The clutch Is buill Into the load brake gear. It is a cone·friction CtutCh that con· nects the lirst recluctl()fl gear (load brake gear) to tha load brake OUtput PInion shaft. A belleville dISC spring provides dutch pressure beIween the gear and its cone shaped gear cent.,. An eXCA$S"Ie 0YerbacI causes lhe load brake gear to rotale Wllhout lurnng the gear CIflIIf and output ~ snatt The clutch IS located betweeo the load bralle and the motor, thus allowIng load brake to luroction in 115 r ..... ,,1I1 manner. See Paragraph 3·5 for operation.

SECTtON II - INSTAlLATION

The frequency for lubricat ion services will depend on lhe type 01 holSllng service tNtt holslls subJecled 10 and .hould coincide with periodic prevenllve mainten­ance Inspection. See SECTION V - M.lntenance.

' ·2. SERVICE AIR LINE LUBRICATOR. servicing air line filler and lubricator unit Is of primary ImPOrtance since 1\'5 the only soorce of lubrication for con1rOI valves and air motor. Fill lubricator with a good grade ollighl spin­dle 011 or air powered tool 011. and follow the manulaclur· er's recommended service procedure.

4,3. LUBRICATE LOAD CHAIN. A small amount of lubri· cent will greally Increase load chain life, theretore, chain should not be allowed to run without lubricant. Chain shoold be cleaoed and lubricated as directed In Para· graph a. below. User shOOld set up a regular schedule for chain lubricatiOn afler ooservlng operating conditions for a few days.

a. Under ordinary conditions only weekly allention will be necessary. Under hot and dlfly conditions it may be necessary to clean chain at least once a day and lubricate It several times between clean. Ings. Thorooghly clean chain with an 011 solven! and relubrlcate by coaling II tightly with graphi te suspension Oil. Make sure that lubricant coatS wear aurlaces belween links.
