Material Handling That’s Automated from Start to Finish Twin-Trak Power & Free Systems link all phases of the production process – from receiving to shipping. Total control is the foremost feature a McGinty conveyor system brings to your operation. Years of experience in overhead enclosed track conveyors enable McGinty engineers to tailor the system to your application, providing you with a conveyor installation that is compatible with existing systems and adaptable to future needs. The result is a materials handling system that enables you to precisely monitor and control the entire production and warehousing process from receiving dock to shipping dock. Because of its superior and accurate control capabilities, Twin-Trak systems are excellent for product finishing applications such as painting, chrome plating, and investment casting. Product is routed through the plant, switched into finishing areas or moved through ovens and dipping stations at precise speeds automatically or manually. This capability makes Twin-Trak ideal for situations involving multiple production lines that must merge into a common finishing facility.

Conventional Twin-Trak The conventional Twin-Trak power and free conveyor consists of two separate tracks – a power track and a free-running load track – mounted side by side. A universal link chain runs in the power track, driven by variable speed power units, and delivers power through pusher dogs mounted in the chain. The pusher dogs engage pusher bars attached to the trolleys on the load track and move them through the conveyor system. In the basic Twin-Trak system, carriers accumulate when the pusher arm is disengaged from the pusher dog by a change in the level of the power track. Carriers are then re-introduced one at a time back into the system, all through the use of carrier holdback and release devices.

Delatching Twin-Trak Carrier accumulation in a delatching Twin-Trak system is accomplished through the use of hinged pusher dogs and cam trails on each free trolley. Actuated by contacting a stop, the pusher dog is cammed out of the way. The dog is counter-weighted, so it will return to the normal position when the preceding carrier has moved out of range, or when it is released. Carriers in the delatching system accumulate automatically when one carrier stops. As the next trolley contacts the cam mounted on the rear of the first carrier, its pusher dog is disconnected from its pusher arm, and so on for each successive carrier. Pusher dogs then bypass all accumulated carriers. When the initial carrier is released, its pusher arm is picked up by the next available pusher do, re-entering the system.

Track The Twin-Trak power and free conveyor systems use two tracks, running in parallel side by side. The power track contains the continuous Zig-Zag chain, and the load track contains the free-running carriers. The track is a tubular section formed from straightened and squared plate steel. Two different weights of track are used. The load track, at 5 pounds per foot, the heaviest in the industry, provides added stability and greater rigidity over longer spans, requiring fewer track supports. The power track is lighter than the load track, weighing 3.5 pounds per foot. The lighter weight track reduces the “dead load” on track hangers and building support structures. Both tracks are available as painted or unpainted at 10’-0” lengths, or stainless steel at 5’-0” lengths.

Chain Designed for maximum flexibility, the Zig-Zag chain consists of a series of alternating vertical wheel and lateral roller units, with wheels on 6” centers, and a maximum chain pull capacity of over 600 pounds. Detachable at any point, this universal-joint like chain handles short radius vertical and horizontal curves with equal success. The vertical wheel units consist of two pressed steel frames connected by an axle and load bar. The lateral units consist of forged steel links fitted with pressed steel wheels. The units are connected by alloy pins and hardened steel rollers which take the tensile loads in all directions. Pusher Dogs Attached to the Zig-Zag power chain, pusher dogs are designed to propel the carrier and to prevent it from running away on slopes. Made of hardened, heat-treated steel and iron castings, pusher dogs may be removed or inserted in the Zig-Zag chain without removing it from the power track.

Drive Units Using the principle of variable frequency, the Twin-Trak multiple drive and single drive units are a dependable source of power which provides automatic load sharing of two or more drive units, while at the same time giving centralized remote speed control. A solid state variable frequency motor speed control (VFMSC) is used to convert 60 Hz. Plant power into variable frequency power. Motor speed is then directly proportional to the frequency supplied by the controller. Speed variation of approximately 5 to 1 can be provided within the capabilities of standard motors and controls. Load sharing between drives in multiple drive conveyors is accomplished through control features built into the VFMSC. Adequate protection is provided for reasonable momentary overloads, and the assembly is also equipped with a friction clutch for protection against excessive overload. All units have 600 pound capacity, with speed variables ranging from 6 to 60 inches per minute, up to 8 to 45 feet per minute.

Take-Up Assemblies Some type of tensioning is necessary on all chain conveyor systems to take up slack created by wear or temperature change. Framed Take-Up Assembly Factory made, ready to be hoisted and hung, this frame provides a rigid base for easy alignment. The frame is permanently mounted; only the actuator and conveyor track move. Tensioning is accomplished with your choice of hardware for screw, spring, or air cylinder operation. Maximum track spread of 10’-0”.

Screw Take-Up Assembly Screw-type take-ups should be used on practically every installation for maintaining the tension on the conveyor chain. The screw take-ups are designed to provide 1’-6” of total adjustment. Air/Spring Take-Up Assembly Air cylinder or spring take-ups are used where there is extensive fluctuation in slack chain caused by extreme temperature variations, and on level systems where the slack chain must be constantly and automatically controlled.

Carrier Insert Section The insert section of track is necessary in any closed loop system. This unit provides the only means for introducing carriers into the load track. For easy accessibility, we recommend that it be located in a low straight track section. Supports should be arranged at both ends of the section.

Inspection Section The inspection section facilitates inspection and maintenance at points other than the drive unit. The unit allows full inspection of the chain for proper lubrication, chain tension, and general condition. The inspection section also permits easy installation and removal of chain. The most desirable location is at the lowest point between the output of the drive unit and the take-up unit. Frog Switches Rugged, compact units with a full frog throw of 5/8”, provide smooth, unhampered carrier movement from one track to another. The die-formed frog plate allows a line-to-line fit of matching parts. Wide track gaps, present in most designs, are eliminated, giving the carrier wheels and load 100% support through the switch. Frog switches can be either manually or automatically controlled, through the use of pull chains, air cylinders, or electric solenoids. When used as an escapement switch, a throw control is not needed; the lateral carrier guide rollers contact the lead angle of the frog plate, shifting it automatically.

Available from stock, in right and left hand, as 12”R x 90° curves or universal radius for use with standard curves. A three-way frog switch is also available in stock.

Standard Carriers All carriers in the Twin-Trak system are equipped with machined steel wheels with a full compliment of steel ball bearings. Wheel pendants are drop-forged and equipped with hardened machined steel thrust rollers for durability and smooth action. Load bars are malleable iron castings complete with bumpers for long wear. The eyes are drop-forged and heat-treated. These carriers and trolleys are designed with jointed load bars. The resulting independent action of each pair of wheels permits a more even load distribution through switches and curves, reducing track and carrier wear.

Tandem Carriers A popular and space efficient application of the Twin-Trak system, tandem carrier movement is often utilized when the load is long and unwieldy. Two carriers, moving in unison at a fixed distance, support and convey the load. When a change of direction is required, parallel track spurs and synchronized frog switches execute 90° curves in as little as 2’-0”. Valuable floor space is saved and load sway is reduced by eliminating awkward swings around a single curve.

Parallel tracks and tandem carriers also enable the user to store a maximum amount of material in a minimum amount of floor space.
