Feedrail FRS100 & FRS200 Plug-In & Trolley Series
Overhead Electrification Systems for Movable Trolley or Stationary Plug-In Service
General Information:Feedrail® systems are capable of providing multi-purpose trolleys or stationary plug-ins for installations requiring a source of electrical power which can be reconfigured without rewiring. These systems provide moveable outlets for electrical power along their entire length. The systems are especially suited for use where conventional wire systems would be cumbersome and costly. Plug-in Jacks with stationary power take-offs, are available for all Feedrail® systems. The busway-supported outlets called “trolleys” (Feedrail® 60 system only) make contact with the enclosed bus bars and provide a continuous moveable connection for electrical devices. The trolleys are easily inserted and removed through door-busway sections. As additional outlets are needed, trolleys (Feedrail® 60 System only) or stationary plug-ins can be quickly and efficiently inserted, their numbers being limited only by the current-carrying capacity of the busway and the capacity of each outlet. Reliable design assures uniform contact pressure, limiting work stoppages due to electrical and mechanical interruptions in supplying power. Advantages of these systems include low installation costs with complete re-usability; ease of adding outlets as required; electrical and personnel safety; compactness; dependability and minimum maintenance expense. All “busway (track) sections” are factory assembled for ease in handling and rapid installation. No special tools are required. Systems are designed for indoor use in non-hazardous, non-corrosive, dry atmosphere. UL & CSA ListedFeedrail® is listed by Underwriter's Laboratories, Inc. (U.L.) under BUSWAYS AND ASSOCIATED FITTINGS (File E11348 for Feedrail® / File E165922 for Electro-Rail® ) and as a CRANE AND HOIST ELECTRIFICATION SYSTEM (File E31188 for Feedrail® ). Feedrail® is also listed by the Canadian Standards Association (C.S.A.) under WIREWAYS AND BUSWAYS (File LL-7907 for Feedrail® / File LL 103287-1 for Electro-Rail® ).

Plug-In Jack Rating: 15 amps continuous.
Voltage
300 VAC, 300 VDC
Track
Track sections consist of a one-piece streamlined 18-gauge zinc coated steel housing and the enclosed current carrying bus bars and insulators, all factory assembled in convenient lengths ready for easy, fool-proof installation on the job. No special tools required. The lower horizontal portions of the housing serve as smooth, rigid runways for the trolleys.
FRS100 & FRS200 Series Track sections are available in various types — Straight, Door, Sectionalizing and Transfer Track sections.
Bus bars are of hard-drawn copper. They are amply proportioned to carry the specified current of 60 amperes per pole continuously, 90 amperes per pole intermittently, without overheating. Bus bar connectors assure full current carrying capacity across the joints without interfering with the free travel of the trolley contacts.
Insulators are made of a high insulating and arc-resistant material. The are locked in place on 9-5/8” centers.
Track Supports
Steel clamp type track hangers for supporting track sections from strap or rod. Track may be supported on up to 10' centers at track joints when used with Duplex Track Hangers. Additional track hangers can be attached at intermediate points. Track should be supported by a minimum of two track hangers per section.
Trolleys
Feedrail® trolleys are designed to provide stable clean power; arcing and hot spots are essentially eliminated. Stable clean power is required for trouble free operation of today’s computer controlled equipment and machinery.
Trolleys are available in both fusible and non-fusible types.
All Feedrail® 2 and 3 Pole trolleys have a chassis-insulator contact assembly. The chassis is of heavy gauge steel. The trolley wheels and guide wheels are of the ball bearing type.
Horizontally mounted ball bearing guide wheels prevent slewing when running in the track. A substantially proportioned insulator block combines the best insulating properties with high arc resistance.
FRS100 and FRS200 Series 2 and 3 Pole trolleys are furnished with three types of contacts:
- COPPER GRAPHITE ROLLER CONTACTS for intermittent movement no in excess of 150 feet per minute
- COPPER GRAPHITE BRUSH CONTACTS for movement up to 250 feet per minute
- BRONZE BRUSH CONTACTS for stationary service
A polarizing tab on the chassis operating in conjunction with a stop in the door track section permits insertion of the trolleys only one way. Equipment grounding may be made through the trolleys. Weights in excess of 20 pounds per trolley are not recommended for moving applications.
Plug-In Jacks
Plug-in Jacks are designed for applications where the mobility of trolleys is not required, such as in some sewing rooms or for connecting lighting fixtures and small tools to Feedrail® track. They can be inserted into the track section at any point. A quarter turn after insertion makes electrical contact with the bus bars and locks the jack in place.
Grounding
For the safety of personnel, the track casings of the Feedrail® system may be used as an equipment grounding conductor for grounding equipment through the individual trolleys and plug-in jacks.
Equipment grounding may be made by using the screw on the underside of the trolley chassis or plug-in jacks or on trolleys or jacks having cabinets of boxes by using the grounding screw within the box. Track housing must be grounded through conduit or other suitable means.
FRS100 & FRS200 Series systems are designed for indoor service in essentially dry locations. Feedrail® systems are electrified tracks in which the current carrying components are enclosed in protective steel housings. Smooth riding internally track supporting trolleys or plug-in jacks take off current and provide electric power for crane and hoist or other types of electrification systems.
The FRS100 & FRS200 Series systems have been specifically developed to provide safe electrification for sewing machines, cloth cutting machines, cloth laying and inspection machines, silk screen printing and drying machines, monorail hoists, light duty cranes and stackers, book binding machines, portable tools on assembly and production lines, radio, TV and appliance test lines, lights for offices, stores, factories, etc.
The FRS100 and FRS200 Series systems are made up of standardized units, factory assembled for fast, complete installation without on-site fabrications. These 2 and 3 pole systems may be used to provide both power and control. They are ideally suited for use on control circuits where other standard Feedrail® systems supply heavier electrification requirements.

2. Insert trolley as shown. If trolley hits polarizing strip, remove, reverse 180° and reinsert. Close track doors. |
Preventative Maintenance
At all times Feedrail® equipment should be so protected and maintained as to be kept clean and dry.
Before the Feedrail® system is placed in operation, it should be thoroughly checked for horizontal and vertical alignment, adequate track support and free movement of trolley travel throughout the entire track run. All track, bus bar and feed connections should be mechanically tight. The system should be checked for possible grounds or short circuits. Any paint, grease, or other foreign matter accumulated during construction should be removed from the bus bars, insulation and track interior. Blow out all dust and other loose particles from inside the track.
Expansion sections, when used, must be properly adjusted, located and supported in accordance with installation instructions. Check bus bars and casing for accurate alignment.
Feedrail® is both an electrical and a moving mechanical system and therefore should be included as a part of your Preventive Maintenance Program.
Electrical Maintenance requires:
- Keeping the system dry and clean to prevent electrical leakage or “shorts” across the insulation.
- Maintaining electrical continuity by keeping bus bar contact surfaces clean and joints tight.
Mechanical Maintenance requires:
- Preventing excessive wear.
- Replacing parts showing excessive wear.
The following Preventive Maintenance procedure, periodically performed, is recommended:
- Remove, thoroughly clean all trolleys and lubricate the wheels. Feedrail® recommends Grade #1 Bearing Grease. This is softer grease than #2 and allows the grease to penetrate the bearings easier. Inspect contacts for excessive wear. Replace worn wheels and contacts.
- Clean bus bars with Feedrail® Bus Bar Cleaner.
- Blow out all foreign particles which have accumulated inside the track.
- Check trolleys for free movement within the track.
- Check all track supports, track joints, bus bar and feed connections for tightness. This procedure should be repeated at regular intervals, consistent with the severity of the operations and usage of the system. Plants operating two or three shifts will require more frequent inspection of the Feedrail® equipment.
Feedrail® is not normally recommended for installations subject to vibration, frequent electrical overload, corrosive fumes and other abnormal conditions. However, should such conditions exist, more frequent inspections and maintenance will be required.
Before additional electrical loads are added to the system, it should be determined that sufficient capacity is available.
