TracVeyor® Conveyors

SSI TracVeyor® Systems are used for warehousing, manufacturing, painting and assembling processes.

The path configuration of TracVeyor® systems is almost limitless in design flexibility. The TracVeyor® may negotiate odd degree turns, cross over railroad tracks, proceed up and down ramps, and in many installations, incorporate special elevators for floor-to-floor transfer.

For added flexibility, the TracVeyor® system can be programmed for index and dwell, for accumulation, or for switching to spur lines.

In manufacturing operations, specially designed indexing stops are available for "work station" processes.

SSI TracVeyor® Chain

SSI X-658 chain assembly for TracVeyor® application features a special "ribbed" center link which circumvents bending and jamming of the chain. Additionally, it facilitates the "telescoping" of the chain in front of the drive unit. The chain's 60,000 lb. ultimate strength provides more than a 10 to 1 safety factor in all installations, and assures long life for the system.

SSI’s rivetless drop-forged steel chain can be assembled and disassembled without special tools.

4-wheel Pusher Dog Assemblies, 2-wheel Idler Assemblies, and other special trolley Configurations can be assembled to SSI’s X-658 chain on any centers of 1 ft. multiples.

SSI TracVeyor® Pusher & Idler Trolleys

SSI TracVeyor® pusher and idler castings are manufactured of malleable iron, providing strong durable units to withstand severe shock and corrosion. Precision ground, polished ball bearing wheels roll with less than 1.5% friction.

The basic 4-wheel trolley is made of malleable iron with a replaceable heat-treated through axle. The Silver Seal trolley wheels are swaged onto the axles for durability. Bolt on wheels are also available.

Three Available Types of Pushers

SSI No. 9009-1 Standard Pusher

Used on non-switching systems, light to medium duty.

SSI No. 9009-2 Switching Pusher

This versatile pusher has special "ears' to guide tow pin into spur lines and can be used on any system.

SSI No. 9009-3 Pusher with Pocket

Designed for non-switching systems for extra heavy duty. The pusher traps the tow pin in the body of the casting and uses the pusher pocket to help guide the tow pin.

SSI No. 9010-1 Standard Idler Trolley

The SSI 2-wheel Idler is available in both malleable iron and aluminum castings. The 2-wheel idler utilizes SSI famous "Silver Seal" large grease capacity rollers which are relubricated through an Alemite grease fitting.

The 2-wheel idler couples to the chain with extended chain pins directly over a standard side link. Idlers should be installed on a maximum of 36" centers to circumvent unnecessary chain sag and wearing of chain pins.

Automatic Lubrication

SSI can furnish automatic chain, chain pin, pusher and idler lubricators upon request. Generally, these lubricators are equipped with automatic timers so that the equipment is in operation for a predetermined period of time during regular preventative maintenance lubrication.

TracVeyor® Roller Turns

Roller turns are available in 48" radius or larger for 30°, 45°, 90°, and 180° configurations. All SSI turns are furnished with high alloy steel top bars, assuring long life and resistance to tow pin wear.

Since the TracVeyor® track is usually imbedded in concrete, long lasting precision ground "sealed-for-life" rollers are furnished as standard equipment on SSI turns.

To assure long life and smooth travel around standard tow line roller turn sections, SSI manufactures this unit with exacting, jig welded accuracy.  Only high carbon steels are used for these roller turns.

Special radii up to 30 ft., and special degree turns, are available. Requirements should be submitted to our engineering staff.

TracVeyor® Clean-Out Equipment

Three (3) types of clean-out boxes are available. A standard debris removal box, a combination clean-out and chain removal box, and a special type "B" clean-out which allows removal of debris while the TracVeyor® is in operation. The special "B" type clean-out has received wide acceptance in facilities where large amounts of debris must be contended with on a daily basis.

Inspection & Clean-Out Boxes

This unit serves as an effective collector of dirt and debris. The cover plate and short track sections are of single piece construction, providing easy access to the box when the cover plate is removed.

Chain Removal & Lubrication Boxes

This box is located on the tight side of the chain immediately prior to the drive unit. Both chain and trolleys may be lubricated at this unit. Additionally, the chain removal box also serves as a debris clean out box.

Type “B” Clean-Out Box

This box is especially suitable for TracVeyor® systems where a considerable amount of foreign debris and dirt continually enter the chain.

One of the many advantages of the type "B" clean out box is increased time between routine cleanouts, due to its greater holding capacity. Additionally, an ordinary shovel may be used to lift the debris.

The cover plates are designed in three (3) sections, facilitating easy removal by one individual performing routine maintenance, without the system being shut down.

TracVeyor® Drive Units

The heart of any conveyor system is its drive assembly.

SSI manufactures high efficiency Caterpillar drive units from 1 through 15 horsepower sizes, with speed ranges of 1 to 180 FPM.

These drives utilize a special heat-treated "Cat Chain Assembly" that engages the main TracVeyor® chain with several dogs simultaneously, assuring non-pulsating, smooth power transmission.  Additionally, the drive may be located on any straight run of the main TracVeyor®.

The drive section is of bolted construction, and may be lifted from the pit as a complete unit.

TracVeyor® drive units are normally limited to 6,000 lbs. chain pull.

TracVeyor® Drive Pits

SSI’s standard TracVeyor® drive pits are 7'-3" long x 5'-2" wide x 4'-0" deep. This economical design is especially appreciated by concrete contractors when pouring the pit. Additionally, the inherent design of the pit is symmetrical about the center line of conveyor and, therefore, either a right-hand or a left-hand TracVeyor® Caterpillar drive may be installed in the pit without modifications.

When desired, larger pits and deeper pits are available to suit an unusual requirement. Normally, SSI furnishes the curb angles to the concrete contractor to set in the forms when pouring the pit. All other work on the drive is handled by SSI’s own field crews.

TracVeyor® Track

SSI TracVeyor® track is available in both welded and bolted top bar construction. We recommend the welded construction because it is more economical, sturdier, and simplifies the installation. With conveyor clean-out and repair boxes strategically located along the path of the system, adequate access to all parts is maintained.

All SSI TracVeyor® Track is jig and fixture welded to assure the close tolerance required for smooth operation of TracVeyor® Systems.  Standard track lengths are 20 ft. sections with saw-cut square ends.

TracVeyor® Spurs

Non-Powered Spurs

The level, "non-powered" spur is the most generally used spur in the industry. The spur can accept conveyor speeds of up to 120 FPM. By utilizing a "spring steel" bumper on the front of the cart, the impact of the bumping action can readily be minimized. Like all other SSI spurs, the non-powered bump-off spur is equipped with a "lockout" safety switch to prevent an excessive number of carts from entering the spur.

Non-Powered Sloped Spurs

This type spur is normally used in a truck terminal operation where long spur lines are required for cart storage, and need to have each cart rolled to the end of the spur. This type of system has proved successful with speeds in excess of 112 FPM. To be completely functional, the tow carts utilized with this type of spur must be accurately maintained with free rolling wheels to accomplish the cart "coast" desired with the sloped spur design.

Partially Powered Spurs

Partially powered spurs are less expensive than fully powered automatic spurs. Generally, they are used when the length of the spur is longer than can be accommodated with a "non-powered" spur. Also accumulation of carts on the dead portion of the spur is accomplished without raising the tow pin or the pin lifting bumpers.

Automatic Spur Lines

Fully powered automatic spur lines are utilized when the less expensive "bump-spur" cannot be used, either due to conveyor system speed or the possibility of damaging the product being handled. Fully powered spurs may be equipped with independent drive motors for the ultimate in flexibility, or the chains may be slave driven from the main conveyor chain.

TracVeyor® Tow Carts

Carts may be a conventional 4-wheel vehicle with a wood deck, or a sophisticated stainless steel cart assembly for special process work. The loads on the cart may vary from a simple cardboard box to a jet engine. Many carts are equipped with special fixtures for product assembly and fabrication.

Many installations utilize existing customer tow carts. However, SSI is equipped to furnish carts, conveyor, wiring and piping for a complete "turn key" installation upon customer request.

Most installations utilize "standard type carts”. For special application, SSI designs and manufactures carts to fit the job requirements.

TracVeyor® Tow Pins

SSI tow pin assemblies may be adapted to existing carts, or furnished with new carts for the project. All tow pins feature free rotation and heat-treated pin assemblies that are both durable and economical.

SSI manufactures both standard and special Tow Pin Assemblies. SSI Part No. 9082 is the most economical pin available for normal TracVeyor® operation.

Special pins are available as depicted with SSI Part No. 9083. All SSI Tow Pins are made from alloy steels, and have rotation capability to prolong the life of the pin assembly. The basic Tow Pin may be replaced without replacement of the entire Tow Pin housing.

Special Pins are available for automatic disengagement and hand or foot releases. TracVeyor® Systems negotiating vertical curves utilize either spring or counterweighted Tow Pins.

TracVeyor® Installation Procedures

Southern Systems recommends that all TracVeyor® installations be performed by our own experienced field crews whenever possible. Our personnel are trained in the most economical and proper method of embedding a TracVeyor® system into concrete.

The following procedures are common for TracVeyor® installations:

1. We recommend a pre-job conference with the concrete contractor before any conveyor material is installed in the floor.
2. SSI's Engineering Department normally prepares the following drawings and specifications:
   1. Complete concrete specifications
   2. Complete path trench layouts
   3. Complete concrete block out layouts
   4. Complete concrete pit details
   5. Complete electrical wiring specifications
   6. Complete control panel diagrams
3. Concrete ditch preparations should be completed prior to arrival of SSI's field crews at the job site, using the drawings prepared by SSI's Engineering Department.
4. When SSI field crews arrive at the job site, they will attach "headers" to all straight track and turns and place in ditch. After the conveyor is leveled and aligned properly, the concrete contractor will make an initial pour to within approximately 2½" of the top of the trench.
5. After the concrete has hardened for approximately 48 hours, the leveling fixtures are removed and the conveyor is ready for the final pour.
6. Prior to final pouring, the track slot should be covered with "tape" to prevent entrance of concrete during pouring.
7. The final pour of concrete should include a hardening agent equal to Master Builders Master Plate to provide a durable, wear resistant floor for the tow carts to run on.  For heavier loads steel caster track should be used.
8. Special care should be exercised with the final pour of concrete to assure a level tow cart path.
9. The initial pours of concrete and the final pours can be properly coordinated with SSI field crews so that there is no "lost time" either by the concrete contractor or our crews.
