Materials handling equipment is of vital importonce in the economical ond efficient performance of all modern industrial operotions where materials are handled and re-handled from their source, through monufacturing and proc-essing. In many cases, materials handling equipment is the only possible means of moving materiols becouse of their characteristics or for other reasons such as location, safety and capacity requirements. In fact, in many plants the pre-dominant operotion is the handling of materials from their raw sta te until they become flnished products.

Materials handling equipment, whether o single unit or a complex system, con link various processes together and synchronize them in a monner not possible b y any other means. Under certain conditions moterials handling units themselves ore often adapted to process materials.

Processing equipment includes such items as Link-Belt screens, d ryers, coolers, mixers, crushers and other related machines.

The successful applicotion of moteriols handling and proc-essing equipment requires a thorough basic knowledge of the capabilities and economies provided by eoch unit as o single machine or in combinotion to form a system. Knowl-edge of the industry ond of the process involved in eoch opplication is of vitol importonce.

producers Materials handling equipment is essential for ecanomical operation of the rapidly expand-ing metal producing industries-steel, aluminum, copper, and all other metal producing plants. Raw and processed ore, fuel and flux meterais for blast furnaces and smelting operations, must be unloaded from can, barges or vessels-and often must be stockpiled, reclaimed, screened, blended, mixed and weighed.

As the metal praducts proceed through vari-ous operations, they must be handled and re-handled in numerous forms, such as ingots, billets, slabs, coils, rods-and flnally, scrap. All equip-ment for such service must be designed for safety, economy and dependability for around-the-clock operation.

Link-Belt affers broad experience and a wide range of equipment for handling materials in all phases of the metal producing industries and is equipped to design, furnish and install com-plete systems for many of the required oper-ations.

bulk handling unloading equipment

unloading equ1pmen for bulk maerials

Unloading common carriers or other means of trans-portation is an important operation in most plants which consume or process bulk materials. Such ma-terials may be received in trucks, trailers, ships, boats, barges, and various types of cars such as mine ca rs, hopper bottoms, gondolas, and boxcars. Requirements may vary from one or two cars per week to sixty or more cars per hour.

Operation of unloading equipment may vary from seasonal or intermittent use at sorne mines, grain elevators, and small plants, to the severe " doy in, doy out" service at steel mills and large steam generating stations. Docks, piers, terminals and other bulk transfer stations require a high degree of dependability and usually high capacities for maximum economy.

Selection of the most effective and economical unloading equipment depends upon the type of carrier to be unloaded, the characteristics and con-dition of the material, the unloading rote, annual tonnage, the means of moving cars or barges to and from unloader, and, in the case of large ships, the cost of demurrage.

Unloading of free flowing materials seldom re-quires considerations other than those of capacity and appropriate type of equipment. Sluggish or sticky materials often require a car shaker for quick, clean discharge of hopper cars, or a rotary dumper for higher capacities. Frozen coal or ore may require thawing to free it from car sides, after which the discharge of moderate capacities of frozen lumps may usually be accelerated by a car shaker. Higher capacities of frozen material can best be unloaded with a rotary car dumper.

The average unloading rote, in cars per hour, in-cludes both the unloading cycle and the time required to move cars to and from the unloading operation. The most effective use of unloading equipment often requires haulage machines or car spotters to reduce the d elays of such movements. Also, feeding and conveying equipment is more economical when the hopper, into which the car is unloaded, is large enough to contain sufficient material to continuously feed the system while cars are shifted to and from the unloading operation.

Various types of bucket elevator unloaders are available for unloading ships of grain, barges of coal and other free flowing materials at capacities up to 2000 or more tons per hour.

Various standard types of unloading equipment are described on the following pages. Link-Belt has built many other types and sizes for unusual con-ditions and Link-Belt engineers are available for a ssisting in the selection of such equipment.

38 L 1 N K - B E L T

Haulage machin es (page 41) are of two types; capstan and drum. They are used for moving railroad cars and mine cars or performing other industrial pulling jobs. Capstan car spotters are compact, sturdy machines which pull b y means of a rape snubbed around the vertical capstan. Drum t ype pullers are generally used for heavier service and larger installations. Both can be arranged with a variety of cable sys-tems for intermittent or continuous op-eration to suit the track layout and the handling of cars at the site.

l / ., \

Fig. 4190

Car shake rs (page 50) are an ef-fective means of emptying hopper bottom railroad cars when the material fails to run out of the open hopper doors by gravity clone. The machine is set on the car after it has been spotted over the track hopper. A motor drives two eccentrically weighted flywheels. Rotation of these flywheels produces a vibration which is transmitted to the car. A short period of operation assists in dislodging material.

Mine car d umper

Rai lroad car du mper

Car dumpers (page 52) provide the most rapid and positive method of emptying all types of open top cars, by turning the enti re car upside down. They are of two forms, one for ra ilroad cars and one for mine cars.

The railroad car dumpers are so designed that when rotation is started, the transfer table supporting the rails moves laterally until the side of the car rests against a timbered side frame of the cradle. Simultaneously with this movement, overhead clamps descend to the top of the car to hold it securely. The cradle rotates until automatically stopped at the inverted position. Operation is then reversed. Rotary car dumpers have been built for dumping more than 60 cars per hour.

Mine car dumpers may b e furnished to dump single cars, coupled or un-coupled, or several cars in a train. Cars are automatically held in place. Dumpers may be designed to rotate through an angle sufficient for dumping and then return, or through a complete revolution. The frame includes a shield to direct and ease the fall of material. Completely controlled by one man, these dumpers are fast, smooth running, durable and foolproof.

Side-tilting type dumpers are also available for dumping refuse. This dumper is semi-automatic in operation and lifts the car vertically, then tilts it to one side to unload the contents.

Power unloading scoops (page 60) are used for unloading grain and other granular materials from boxcars and trucks into hoppers, and for other similar operations. They enable one man to perform tasks which would require the efforts of several men by manual methods. The operator draws the scoop back over the material a suitable distance, and then allows slack in the rape. This starts the winding mechanism, which pulls the scoop forward to push the material to the discharge point while the operator holds the scoop upright by its handles.

Boxear unloaders (poge 62)

Kor-Flo boxear unlooder, including spotting to unlooding, will handle up to 5 cars per hour of grain, chemicals, or other free-flowing bulk materials. The cor is moved on the self-contained unloader platform, ond is clamped hydraulically. The inner d oor of car is opened hydraulicolly.

One rail is instolled higher than the other to give o side tilt to the car. A drive unit creotes a unique rocking motion which conveys the material simultoneously from both ends toward the center of the car causing contents to flow smooth ly and continuously to a receiving hopper below.

One man controls the unlooding operation. Shallow pit and low overheod el ea ronce requirements keep instollotion costs ot o mnimum.

Tilting type boxear unlooder is o machine for dumping grains and other free-flowing bulk materiols from railrood boxcars by tilting the cars both loterally and longitudinolly. The unloader has o moin cradle ond clomps which hold and automatically center the car. The car supporting plotform mounted on the cradle is first tipped side-wise about l 5 degrees, while the inner door is forced inward. The car is then tilted endwise about 40 degrees in both directions, with a baffle plate inserted on the final tip to deflect the last remoining material.

lnstallotions are efficient and economical for extensive operations that involve up to 6 to l O cars per hour.

bulk handling haulage machines

machines For many years Link-Belt has designed and manufactured haulage machines and systems for handling a wide range of mobile loads. While commonly used for moving railroad cars, there are numerous other industrial applications where haulage machines are being successfully used for pulling heavy trucks into and out of shops, warping vessels through drawbridges and along docks, for mooring service on canal barges, for pulling cars of castings into and out of furnaces, and for moving cars into and out of core ovens and dry kilns. They are used in foundries for pulling flasks over roll tables, dragging heavy materials along the ground and wherever rope pulls up to the maximum capacity of the machines can be used advantageously.

These machines are economical to operate, as power is consumed only when they are in actual operation. Their use has resulted in marked savings due to elimination of switch-

Link-Belt haulage machines are of two types-car spotters which pull loods by meons of o rope wrapped around a vertical capstan, and drum-type pullers which exert pulling action through a rope wound upon a horizontal drum.

Car spotters

Link-Belt car spotters are made in two sizes and three types. A sturdy, compact gray iron housing completely encloses and protects the splash-lubricated gears and ball bearings. A capsta n made of hard iron, for use with manila or marline covere d wire rope, is pro-portione d to obtain maximum traction and pulling power. The capstan face is machine flnished to prolong life of rope. The worm and helical gears are precision cut to exacting speciflcations. The steel capstan shaft runs in bronze sleeve bearings. A ratchet and pawl can be furnished and installed within the capstan when the spotter is required to hold cars on an incline.

Accessories such as haulage ropes, car pulling hooks, sheaves and snatch blocks can be furnished.

Selection Calculation of rope pull for railroad cars To determine the rope pull required to move o roilrood cor using either o cor spotter or drum-type puller with ploin drum, it is necessory to consider the following foctors:

Weight of cor ond conlenls Curvoture of !rock Trock grade Trock ond roodbed condition Temperoture of surrounding otmosphere

Cors, other thon roilrood cors, will require speciol considerotion. Consult Link Belt.

Weight of car and contents The weight of cor ond contenls is the gross weight in tons.

Track curvature Trock curvoture is expressed in terms of rodius in feet, degrees of curvoture or by chordol fac tor A. The degree of curvoture is the included ongle in d egrees fo r o 1 00-foot chord ocross the center line of !he !rock. Factor A is !he chordol distonce for o 50-foot chord on the inside roil. To obtoin !he chordol factor, stretch o 50-foot line ocross !he curve ond meosure A os in Fig . 3704.

Rope pull for pulling railroad cars The sto rting rope pull is found b y the following formulo:

P = W (B+ C) Where P = storting ro pe pull in pounds

W = weight of cor ond contents, in tons B = factor from Table 1 C = factor from Table 2

Examples of rope pull calculations Problem 1 A roilrood cor ond its contents weighing 42.5 tons is to be moved olong o curved leve! !rock where A equols 9 '!4 ". The operoting tem-peroture is never lower !han 45F al ony time. The !rock is uneven ond has o soft bollost. Colculote the storting rope pull. Solution In Table 1, Factor B = 45 ond in Table 2, Factor C - 9.

storting rope p ull = 42.5 (45 + 9) = 2295 pounds Refer to !he selection tables on the following poge. A No. 50, 55 or 60 cor spotter is sotisfoctory . Problem 2 Four roilrood cors ond their contenls weighing 220 tons ore to be moved olong o curved !rock al obout 35 FPM where A equols 6 Y2". Trock rises 3 feel in eoch 100 feet. The operoting temperoture will foil below O F. The !rock is even ond has o firm bollos!. Colculote the storting rope pull.

Solution 3 X 100

grade = ---)() = 3% In Tab le 1, Factor B = 100 ond in Table 2, Factor C = 6.

storting rope p ull = 220 ( 100 + 6) = 23,320 pounds Refer to the selection tables on !he following poge. A No. 2024-20 drum-type puller, which operotes ot 36 FPM, is sotisfoctory.

The Link-Belt car shaker is an ideal medium for effectively and economically unloading hopper bottom railroad cars. lt produces a series of heavy, hammer-like blows on the top of the car sides, which loasen the contained material and accelerate its Aow through the hopper opening, re-sulting in broom-clean unloading.

This machine supplements our varied line of car dumpers and unloaders and offers an economical car emptying device for installations requiring moderate or small ca-pacities. lt is ideal for use at central power stations and industrial boiler houses, where the quantity of coal used does not require a rotary car dumper. lt is also suitable for unloading sand, coke, ore, cinders and other materials transported in hopper bottom cars.

Link-Belt car shakers can be appl ied to single or multiple track and single or double hopper installations.

Operation

The vibrator is located toward one end of the welded, stress-relieved frame and consists of two eccentrically weighted flywheels keyed to each end of a concentric shaH rotating in self-aligning roller bearings. Power for operating the unit is supplied by an electric motor driving through a multi -ple V-belt drive. Extreme vibration and impact shock is prevented from reach -ing the motor by means of a pivoted, rubber-mounted motor platform.

To unload , the cars are moved into place over conventional track hoppers in the usual manner by car hauls, car spotters, switch engines or other means . After the car gales hove been opened, the car shaker is lowered into place on the center portian of the car and the motor started. Operation of the machine causes the vibrator end of the frame to rise and fall and impart heavy blows to the car equal in number to the revo lutions of the vibra-tor shaft. The motor end pivots on the car top and acts as a guide to ho ld the shaker in place.

The action of the car shaker also causes lengthwise motion of the car, resulting in a conveying action on the hopper bottom. Upon completio n of unloading, the shaker is raised out of the way, the car doors closed, and another car moved into position. Ca rs need not be un-coupled while the shaker is in operation, permitting movement of cars through the unloading zone as a com -plete train . The shaker eliminates the destructive o r dan -gerous use of picks, augers, sledges or air hammers . W ith the vibrator shaft revolving ata comparatively moderate rote of speed, a much lower o perating sound level is ob-tained than with other machines operating at higher fre-quencies. Objectionable noise is correspondingly less, and damage to the cars is no more than that encountered in normal operation over roed bed .

Capacity The rote of car un loading will vary with the natu re of the material in the car, the design of the car, car switch-ing and stori ng facilities and the rote at which materia ls can be conveyed from the track hopper. Normally, a one to three minute operation of the shoker w ill completely empty the car. Sticky or frozen materials may require additional time. Extremely frozen cars should be partially thawed .

Hoists Where conditions permit, single-hook five- ton capacity stationary or power-propelled, motor operated hoists may be used for lowering the shaker into position . For ground levef control, twin -hook hoists a re preferred, as this type machine will lower the shaker onto the car without guidance. l t is recommended that hoists be equipped with lower l imit or slack line switches t o prevent operation of the shaker unti l it is properly p laced on the car. Yard cranes and similar hoisting equipment can be used to handle car shakers.

bulk handling car dumpers

car dumpers Link-Belt car dumpers rapidl y and economically unload all

types of open-top cars carrying bulk materials. They are used at power houses, mines, by -product plants, steel milis, rail- to-water transfer docks, cement mi li s, smelters, concentrators, aluminum plants and sugar reflneries, for unloading such materials as coal, coke, rock, ore, sugar beets and sugar cene.

Four types of car dumpers are available, each designed to unload a car by rotating, tilting, or over-turning and dumping the contents into a receiving hopper, in one operation. These four types are:

Rotary railroad car dumpers. Rotary mine car dumpers for single cars or multiple cars coupled in a train. Side tilting and transfer refuse car dumpers. Side discharge railroad car dumpers.

All types embody Link-Belt's valuable background of experience in the application of unloading equipment and the handling of bulk materials.
