HAS ACCESS TO AREAS YOUR EMPLOYEES ARE NOT TO ENTER Rapid Conveyors transport your product through process areas such as washing and painting booths, furnaces and ovens, freeze rooms or booths where extreme hot/cold temperatures prevent personnel from entering. 2. ACCOMPLISHES WHAT YOUR EMPLOYEES CANNOT Where solvents, acids, or dust prevent the presence of your employees, your parts can be degreased, dipped, plated, coated or painted, all automatically. 3. ASSITS YOUR EMPLOYEES IN PRODUCTION OPERATIONS Rapid Overhead Conveyors carry your parts or assemblies to your employees where they can efficiently perform their task and then to the succeeding stages in the manufacturing process, all automatically and at a rate that YOU determine. 4. GREATER WEIGHT CARRYING CAPABILITIES THAN AN EMPLOYEE A Rapid Overhead Conveyor will carry continuously its maximum load suspended from each trolley over the entire route of the conveyor system. Each trolley may carry either single or multiple items depending on its shape and weight. 5. NEVER TIRES OR NEEDS BREAKS A Rapid Conveyor works 24 hours a day for weeks on end and automatic lubrication and minimal maintenance result in the enviable record. 6. SETS RATE OF PRODUCTION With variable speed drive, the system will permit you to control rate of travel of your parts or materials to maximize efficiency and production capabilities. 7. EFFICIENT USE OF SPACE Our system uses little or no floor space which is an important element in today’s competitive market. Often, a Rapid System can be installed where a floor conveyor would be precluded due to space limitations. 8. CONTROLLS QUALITY OF PRODUCTION A Rapid System eliminates most manual handling, loading/unloading and transporting of your product by your employees. With a reduction in the contacts of your product with personnel, quality is noticeably improved. 9. PRODUCTIVITY IS IMPROVED A system also delivers a continuous flow of material or parts to and from each production area. Your personnel become more efficient and productive because the parts or materials they need are there on schedule and easily accessible. 10. REDUCES PER UNIT COSTS A system eliminates most of the manual handling of parts or materials. By doing so, considerable lost motion is also eliminated resulting in a reduction of per unit costs. 11. EXPEDITES INSPECTION A Rapid System permits a continuous inspection process instead of a batch method where delays are inherent in the handling of item to be inspected. 12. MORE EFFICIENT PACKAGING AND SHIPPING Finally, a Rapid system will deliver to packaging equipment a steady flow of product or material at a predetermined rate compatible with capacity. Shipping will then receive a steady output of product that can be more readily accommodated. 4 GLOSSARY OF CONVEYOR TERMS ACCUMULATING AIR-OPERATED TAKEUP An assembly of the structural and mechanical parts which provides the means to adjust the length of the power chain by the use of an air cylinder to compensate for chain stretch, shrink, or wear and to maintain proper tension. ANTIBACKUP A mechanical safety device to prevent reversal of a loaded conveyor under action of gravity when forward travel is interrupted. ANTIRUNAWAY A safety device to stop a declining conveyor and thus prevent running away in event of an electrical or mechanical failure. AUTOMATIC LUBRICATOR Automatically lubricates chain, trolley wheels or other components as they pass. BACKSTOP Mechanical device used to prevent reversal of a loaded conveyor under action of gravity when forward travel is interrupted. An antibackup. BACKUP BAR Heat treated bar drive component used to back up the caterpillar chain dogs. BACKUP ROLLERS Series of rollers mounted in the drive to retain the conveyor chain in proper relation to the caterpillar chain dogs. BALANCED DRIVED Two or more drives on one conveyor chain each driving the conveyor with a predetermined share of the load with synchronized speed. BEAM CLAMP Device for gripping the flange of supporting beams or trusses for the purpose of suspending a conveyor frame or track. BEAVER TAIL Tail plate or after configuration of a free trolley that, when engaged with the duck bill or lever arm and bumper on successive trolleys, permits accumulation of the free trolleys. “B” / BOLT ATTACHMENT Trolley attachment with threaded rod projection for attaching load bar or various objects. “C” / PENDANT ATTACHMENT Trolley attachment projecting through chain having a single hole for supporting loads. CATERPILLAR CHAIN Short endless chain on which dogs or teeth are spaced to move a conveyor power chain. CATERPILLAR CHAIN DOG Dog or tooth attached to a caterpillar drive chain to provide the driving contact with the conveyor power chain. CATERPILLAR DRIVE Drive equipped with a caterpillar chain to propelling the conveyor power chain. CATERPILLAR TAKEUP SPROCKET Non-driving sprocket of a caterpillar drive which is adjustable to tension the chain. CENTER LINK Loop-shaped link of rivet less chain which provides the bearing surfaces for the pins and permits passage of the trolley load support members through the chain. CHAIN PIN Pin used to connect succeeding links of a chain about which the link pivots. CHANGE OF ELEVATION Vertical distance between the upper horizontal tracks of a vertical curve to the corresponding point on the lower horizontal track. CLEVIS PIN ATTACHMENT Forged chain pin with a clevis on one end used for supporting light loads from a trolley conveyor chain between trolleys. COMPOUND VERTICAL CURVE Assembly of two single vertical curves with connecting tracks that change the elevation. CONVEYOR GUARD Structure mounted below the conveyor path to protect personnel and equipment below. COUNTERWEIGHTED TAKEUP An assembly of the necessary structural and mechanical parts which provides the means to adjust the length of the power chain by the use of counter-weights to compensate for chain stretch, shrink, or wear and to maintain proper tension. DRIVE FRAME Structure which supports the drive shaft assembly and machine parts which contains the motive power or supports the assembly to which the motive power is connected. DRIVE SHAFT Main driving shaft on which the conveyor sprocket is mounted. 5 DRIVE SPROCKET Driving sprocket of a caterpillar drive or of a sprocket drive. DROP Vertical distance from the top of the I-Beam track to the centerline of the power chain. DROP SECTION A section of free track that can be lowered hydraulically, pneumatically or by electrical means, to pick up a load and return to the original elevation of the adjacent power and free track to permit the trolleys on the drop section to enter the rest of the overhead conveyor system. DUCK BILL Actuating lever on the forward end of a free trolley, that, when engaged with the beaver tail or after plate configuration of preceding trolleys, will retract the power dog on the free trolley, disengaging it from the power chain and permitting accumulation of the free trolleys. FROG The diversion mechanism in a switch that may be manually operated or powered. “H” / CLEVIS ATTACHMENTS A forked or clevis type trolley attachment to suspend a load. HANGER STEEL Structural members by which a conveyor is hung from supports. HEADER STEEL Steel framing supporting the overhead conveyor track with all trolleys, chain and the total load including product and hangers. “I” / IDLER ATTACHMENT An attachment used to complete the assembly of a no-load carrying trolley. KICKER A roller bank turn or traction wheel used to align the power chain to the centerline of the track in horizontal deviations of 45° or less. LINK A chain unit of one pitch length. LOAD BAR A device used to distribute a load over pairs of trolleys. MULTIPLE DRIVES Two or more motorized drives applied to a single conveyor for the purpose of reducing the chain tension in any given section. “C” / PENDANT ATTACHMENT Single bar trolley attachment projecting through the chain having a single hole for supporting loads. PICK-AND-PLACE The loading/unloading an overhead system using automated modules or robots. POWER & FREE Overhead conveyor incorporating multiple tracks, generally one over the other. The lower track supports the load carrying trolleys while the power chain is suspended from the upper track. POWER DOG The forward tooth or “dog” on a free trolley of a power and free conveyor that will place the free trolley in motion. POWER ONLY One track system with chain propelling the trolleys from which the product is suspended. PRESSURE ROLLER A hardened tubing with integral bearings used to align the power chain to the centerline of the track. Also known as a segment roller. PUSHER DOG A tooth or “dog” on the power chain of a power and free conveyor that, when engaged with the power dog of a free trolley, places it in motion.
