For most bulk material elevating jobs. . . there's a Link-Belt BucketElevator that will handle themefficiently and economically. Withover 100 years of proven experienceas a pioneer and leading producer ofbucket elevators, FMC Technologiesoffers a standardized line of Link-Belt™ elevators proven in thousandsof installations.

Standardization is a standout featureof Link-Belt Bucket Elevators. Link-Belt Type 1 and Type 7 BucketElevator designs are standardized soyou benefit from the economics ofmany stocked components.Manufacturing methods arestandardized through exactingproduction and fabrication to assurecompatibility of components.Engineering and order processingprocedures have also beenstandardized so that the selectedelevator will accommodate yourneeds with a minimum of time andcorrespondence.

Balanced design of components,manufacturing craftsmanship, andthe quality found in all Link-Beltproducts, have all helped the Link-Belt Bucket Elevator achieveuniversal acceptance.

Two basic designs of bucketelevators are available, and selectiondepends primarily on the material tobe handled.

The Centrifugal Discharge designhas spaced buckets that travel at arelatively high speed. It is a mediumcapacity unit, capable of handlingmaterials with small-to-medium sizelumps. The buckets dig the materialfrom the casing boot section anddischarge it by centrifugal force.

Type 1- Elevators of this type meetthe service requirements of themajority of installations usingcentrifugal discharge elevators. Thehead shafts are fixed, with the footshaft takeup being internal gravitytype. Buckets are designed for useon either chain or belt.

For most applications, chain isrecommended, however, belting isused when handling materials thatmust not be contaminated or formaterials that are extremely abrasiveand corrosive.

As an alternate to the standardType 1 centrifugal dischargedesign, Type 2 design isavailable. The head shaft isadjustable and the boot shaftfixed to maintain the relationshipof buckets to the inlet spout andcurved bottom plate. Type 2bucket elevators arerecommended when handlingfood products; for materials thattend to pack or build-up, or whenhandling materials having alarge percentage of lumps.

The Continuous Discharge Designhas buckets mounted continuouslythat travel at a much slower speed.The continuous discharge designelevator handles a variety ofmaterials from fines to large lumps.Materials that are difficult to pick inthe casing boot section or friable arenormally handled in this typeelevator. The buckets are fed directlyfrom a loading leg or chute and areemptied by gravity at the dischargepoint.

Type 7-This elevator is the mostfrequently used of the continuousdischarge design. The head shaftsare fixed, with foot shaft takeupsbeing internal gravity type. Bucketsare steel and spaced continuouslyon a strand of chain.

As an alternate to the standardType 7 continuous dischargedesign, the Type 8 design isavailable. The head shaft isadjustable and the foot shaft isfixed. Type 8 elevators are usedfor the handling of fine orcrushed materials with lumpsnot exceeding 1/2 inch. With theaddition of a loading leg and acorrespondingly higher inletspout, this type elevator canalso be used for handling lumpsup to 41/2 ".

The superior performance deliveredby the Link-Belt Bucket Elevator isthe result of quality components,and each component described inthis catalog has been developed asan integral part of a carefullyengineered elevator design. FMCTechnologies maintains a largeinventory of bucket elevatorcomponents to meet yourreplacement needs.

A centrifugal discharge bucketelevator-rugged construction withquality components-industry's leaderin the handling of free-flowing, fineand loose material with small tomedium size lumps.

Bucket spacing and speed isimportant for centrifugal dischargebucket elevators. The Link-Belt™Type 1 Bucket Elevator can be reliedupon to elevate and dischargematerials at rated capacities.

In selection of quality components,FMC Technologies engineers have,based upon laboratory tests, takeninto consideration the critical speedof operation that exists with bucketelevators. The critical speed ofoperation is the speed at which theactual capacity of the elevator dropsbelow the theoretical capacity, andexists when the centrifugal force atthe mass center of the material inthe bucket is equal to thegravitational force on the material. AllLink-Belt™ centrifugal type dischargebucket elevators operate below thecritical speed.

Years of dependable, service-provenperformance with built-in qualitydesign features-your assurance ofmaximum efficiency:• Properly spaced buckets, mountedon durable, strong chain or toughwear resistant belt, to provide themost efficient operation per dollarinvested. Belt elevators with Link-Belt™ wing-type pulleys arerecommended when handling bulkmaterials with abrasivecharacteristics, moderatetemperatures or excessive moisturecontent.

• Fixed head shaft with an internalgravity actuated takeup in the boot.Bearings on the takeup frame arehard iron, with the takeup shafthaving induction hardened journals.

• Boot section is totally enclosed withlarge inspection doors to facilitatebearing replacement or the removalof the entire takeup frame.

• Hood section is removable in twosections, and the use of waste packseals provide added protection forthe head shaft. •Standard drive is a shaft mountedspeed reducer with a built-inbackstop. Other drives are available.

• The rigid, strong, jig-built casingsare fabricated from steel plate foryears of rugged operation.• Continuously welded casings arealso available.
