3 We recommend that youstudy its content thoroughly before putting your hoist into use. Then,thru proper installation, application of correct operating procedures,and by practicing the recommended maintenance suggestions you willbe assured maximum lifting SERVICE from the inspection, maintenance and overhaul SERVICE is availablefor Budgit Electric Hoists at Authorized Repair Stations. All are staffedby qualified factory-trained SERVICE men; have authorized testingequipment; and stock a complete inventory of factory approved Budgitreplacement replacement PARTS information is given in Section IX. It willlikely be a long time before PARTS information is needed, therefore,after you completely familiarized yourself with operation and preventivemaintenance procedures, we suggest that this instruction and partsmanual be carefully filed for future : Use only factory approved Budgit replacement PARTS , availablefrom Authorized Repair Stations or Budgit Hoist Accident Prevention MANUAL for Industrial operations (8th Edition)by the National Safety Council states: Employees who work near cranes or assist in hooking on or arrangingloads should be instructed to keep out from under loads.

4 Supervisorsshould watch closely to see that this rule is strictly safety standpoint, one factor is paramount: conduct all liftingoperations in such a manner that if there were an equipment failure,no personnel would be injured. This means keep out from under raisedloads! THE INFORMATION CONTAINED IN THIS MANUAL IS FORINFORMATIONAL PURPOSES ONLY AND BUDGIT HOISTS DOESNOT WARRANT OR OTHERWISE GUARANTEE (IMPLIEDLY OREXPRESSLY) ANYTHING OTHER THAN THE COMPONENTS THATBUDGIT MANUFACTURES AND ASSUMES NO LEGALRESPONSIBILITY (INCLUDING, BUT NOT LIMITED TOCONSEQUENTIAL DAMAGES) FOR INFORMATION CONTAINED INTHIS : Information contained in this book is subject to change without 3 SECTION I - GENERAL DESCRIPTION1-1. GENERAL. Budgit Portable Electric Hoists are precisionbuilt chain type hoists ranging in six rated load sizes from 1/4ton thru 3 tons with various lifting speeds and electrical powersupplies.

5 In addition to the capacities, there are model variationswith roller or link type load chains, hook or lug type suspension,and single or two speed. In addition to standard models, thereare four rated load sizes of Budgit Electric Hoists ranging from1/4 ton thru 2 tons suitable for plating hoist SERVICE with variouslifting speeds and electrical HOIST SERVICE CLASSIFICATIONa. Budgit electric hoists at the time of manufacture complywith our interpretation of applicable sections of ANSI Overhead Hoists , National Electric Code ANSI/ NFPA 70 andOccupational Safety and Health Act, OSHA places the burden of compliance for hoist installationson the user. The user must install the equipment in accordancewith the National Electric Code ANSI/NFPA 70 as well as otherfederal, state and local regulations which apply to the installationand application in your particular equipment is not designed or suitable as a powersource for lifting or lowering These hoists meet ANSI/ASME HST-1M PerformanceStandard for Electric Chain Hoists hoist duty class ratings asoutlined in the sales BASIC CONSTRUCTION.

6 All sizes and models of theseBudgit Electric Hoists are of the same basic designs, havingmany common and interchangeable PARTS . They consist primarilyof an aluminum alloy frame and gear case cover which housesan automatic load brake and gear train. An electric drivingmotor and external motor brake are mounted on the rear of theframe, Electrical control components are mounted on front ofthe gear case cover and encased by aluminum alloy end upper hook or lug bracket for suspending the hoist isattached to the top of the frame. Either a special nickel steelroller load chain or high strength low alloy coil load chain withlower block assembly is employed to raise and lower loads. Ablock and chain operated limit stop lever is mounted on theFigure 1-1.

7 Hoist operation is controlled by a pendant pushbutton DIFFERENCES BETWEEN MODEL AND SIZES. The maindifferences between hoist models are in the serviceclassification, type of load chain and the suspension are described in paragraphs (a) thru (d), below. Thedifferences between sizes of hoists are in the number of gearreductions used and the reeving of the load chain. Two-reductiongearing is used for 1/4 thru 1/2 ton rated load hoists; three-reduction gearing for 1, 2 and 3 ton rated hoists. On 1/4 thru 1ton rated load hoists, the load chain is single reeved (one partof chain); on 2 ton rated loads, the chain is double reeved (twoparts of chain); on three ton rated loads, the chain is triplereeved (three PARTS of chain).a. Two different types of load chains are used as the liftingmedium, roller chain and link chain.

8 The roller type chain is aspecial precision manufactured nickel steel chain. Link typechain is full-flexing electric welded link chain. Both are especiallydesigned for use in Budgit Electric Hoists and only factoryapproved chain of the correct size, pitch, hardness, and strengthcan be used with these Suspension differences include a conventional hook typemounting and a lug type mounting. Hook suspension allowsportability permitting hoist to be easily moved from job to suspension permits hoist to be rigidly mounted to overheadstructure or attached to Budgit Rigid Mount Trolleys, affordingunusual headroom Some hoists are adaptations of standard model hoists topermit use in some mildly corrosive atmospheres, high ambienttemperatures and high duty cycle operation. They are availableonly in link chain models in either hook or lug variations from standard models are as follows:(1) Load chain is zinc plated for corrosion resistance.

9 (2) All exposed aluminum PARTS are prime painted withcorrosion resistant paint.(3) Aluminum castings are specially MAN-GUARD OVERLOAD CLUTCH. Budgit Electric Hoistshaving a MAN-GUARD label on the sides of the electricalcompartment cover (fig. 1-2) are equipped with an overloadclutch that is designed to help guard against excessiveoverloads. The clutch is built into the load brake gear. It is acone-friction clutch that connects the first reduction gear (loadbrake gear) to the load brake output pinion shaft. A bellevilledisc spring provides clutch pressure between the gear and itscone shaped gear center. An excessive overload causes theload brake gear to rotate without turning the gear center andoutput pinion shaft. The clutch is located between the loadbrake and the motor, thus allowing both load brake and motorbrake to function in their normal manner.

10 See paragraph 3-5for On hook suspended hoists, select a suitable overheadsupport in area hoist is to be used (one capable of holdingweight of hoist and its rated load) and hang up hoist. Be certainupper hook is firmly seated in center of hook saddle. Upperhook is equipped with a spring type hook latch; it may benecessary to remove latch to attach hook to support. Replacelatch after hoist is On lug suspended hoists, select a suitable overhead supportin area hoist is to be used (one capable of holding weight ofhoist and its rated load). Mount hoist using thru bolts, ofappropriate size, to fit mounting holes in suspension lug at topof hoist frame. (See table below.) The structure used to suspendhoist must be of sufficient strength to withstand reasonableforces to which hoist and support may be subjected.
