Feedrail FR100 Series Trolley Service
Busway and Crane & Hoist Electrification System for Movable Trolley 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. |

FR100 Trolley Series (Feedrail® “100”) — What It Is and What It Does
Feedrail® “100” is the modern flexible “Trolley Busway System” and “Crane and Hoist Electrification System” for distributing electric power. Basically, it is an electrified track in which the current carrying components are enclosed in a protective steel housing. Smooth riding internally track-supported trolleys take off current and provide power outlets anywhere along the length of the run.
Superior to ordinary wiring methods in safety, convenience and adaptability, it provides a dependable power source for both stationary and moving equipment. Its uses in industry are myriad — from powering hoists and cranes to providing current for portable electric tools, from the electrification of moving test lines to the control of large machine tools and to supplying the current for electrically driven hangar doors.
The Feedrail® “100” system is made up of standardized units, factory assembled for easy, fool-proof installation in the field. Its basic units include:
Track sections — straight, curved, door, expansions, sectionalizing and transfer sections — enclosing current carrying bus bars.
Accessories — coupling plates for joining track sections; feed boxes for connection of bus bars to the electric power supply; dead end caps for closing the end of track runs.
Trolleys — available in several types to meet a wide range of requirements including fusible and non-fusible types, with and without receptacles — internally track supported to provide current takeoff wherever desired.
Track sections can be supplied to form runs of any required length or contour. Hence it is “tailored-to-fit” the electric power requirements of industry, whether for modernizing an existing plant or for installation in a plant under construction.
Feedrail® “100” operates with equal safety of any required level from ceiling to floor. While the majority of installations are overhead, numerous low-level installations have been made, including some along the base of production lines. All installations have proven entirely satisfactory in operation.
Designed primarily for indoor service in essentially dry locations.

Current Carrying Capacity
Current Carrying CapacityTrack rating 100 Amperes (continuous); 150 Amperes (intermittent) Trolleys rated 20, 30, 40, 60 and 100 Amperes (continuous).
Voltage
600 Volts A.C. — 250 Volts D.C.
Track Supports
Malleable iron clevis type for tie rod. Fits all track accessories.
Track
TrackTrack sections consist of a 13-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. The lower horizontal portions of the housing serve as smooth, rigid runways for the trolleys.
“100” Track sections are available in various types — Plain, Door, Sectionalizing, Transfer, Curved and Expansion Track Sections.
Bus bars are of hard drawn copper. They are amply proportioned to carry the specified current of 100 amperes per pole continuously, 150 amperes per pole intermittently, without overheating. Insulators are made of a high insulating and arc-resistant material. They are held in place on 9” centers by the casing.
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 fusible and non-fusible types.
Basically, all Feedrail® “100” trolleys have a chassis-insulator-contact assembly. The chassis is heavy gauge steel. The trolley wheels and guide wheels are of the ball bearing type. A substantially proportioned insulator block combines the best insulating properties with high arc-resistance.
The trolleys for the “100” track system are furnished with various types of contacts. Bronze ROLLER contacts rated 20 Amperes, Copper Graphite BRUSH contacts rated 30 Amperes and Silver Tungsten Brush contacts rated 30 and 100 Amperes.
All Feedrail® trolleys have a polarizing tab on the chassis, which, operating in conjunction with a stop within the door track, permits insertion of the trolley one way only, thereby maintaining the trolley polarity as first wired. Provision for equipment grounding is included on all trolleys.
Feedrail® “100” system Roller Contact Trolleys generally are for intermittent movement applications where speeds do not exceed 200 feet per minute. Feedrail® “100” system Brush Contact Trolleys are for more frequent moving application such as on cranes and monorails where speeds do not exceed 350 feet per minute. Where continuous movement is required at these speeds, or where low voltage (under 50 volts) or low current (under 1 Amp.) is required, consult technical service group for recommendations. Weights in excess of 40 pounds per trolley are not recommended.
Cranes and Hoists
|
Because it eliminates the dangers and susceptibility to damage inherent in open wiring, and lowers maintenance costs, Feedrail® “100” is widely used for powering electric cranes and hoists. As these photos show it is readily adaptable to all kinds of installations, including those with curves, switches and transfers. |

Installing “100” Track
Feedrail® “100” track, trolleys and accessories are designed for ready installation without field alteration. Any qualified electrician can do the job. No special tools are required.
Installation should begin at a transfer or switch point or at an expansion track section if these are included in a track run. Otherwise, start at the feed box (center feed or end feed) and proceed away from that point.
The following four steps should be performed in the order given:
- Install hanger rods or other supports to which Feedrail® “100” is to be attached.
- Assemble Feedrail® components. The illustrations on the following pages show the step by step procedure. In many cases the assembling of Feedrail® “100” can be facilitated by coupling two or more sections prior to rising into position.
- Attach Feedrail® to supports, making sure adjoining track sections are on the same level and in correct alignment before the track connecting bars and bus bars are secured.
- Connect electrical supply cables to terminals of feed box.
NOTE: Where Feedrail® equipment has been ordered to the job site in advance of actual installation, the equipment should be carefully stored indoors in a clean, dry area.
Feedrail® “100” is designed primarily for indoor service in essentially dry locations.
Installing Transfer Track
Transfer Track sections are similar to Plain Track sections except that one or both ends are flared and have a tapered insulator serving as a guide for entrance of the trolleys.
On installations having transfer points, (turntables, slide or tongue switches, hangar door tail-gates, etc.) the Transfer Track sections should be installed first so that proper gaps can be set. These gaps between Transfer Track sections should not exceed ¼ inch.
(Transfer Track sections for use on turntables and slide switches, are not stock items but are manufactured specifically to conform to given dimensions.)
Where motor propelled hoists are used on runs which include transfer points, it is necessary to use two electrically interconnected trolleys. The two trolleys must be spaced sufficiently so that current is maintained to one trolley while the other crosses the transfer point. Duplex Transfer Type Trolleys have been designed particularly for this application.
Transfer Track sections at transfer points must be aligned accurately, both horizontally and vertically. They must be supported at the transfer ends by an FR-124 Transfer Point Hanger Set. (Hook bottoms of Transfer Point Hanger Set into slots in the under edges of the track housing. Bring the plates together and fasten to support with bolts as shown).
In every case the mounting of Transfer Track sections should be designed to insure a rigid installation. They should be sway braced to maintain alignment.
Sections are installed and coupled to adjoining track sections as shown in Joining Sections With Coupling Plate Set FR-102.
Building Expansion Track
At least one Expansion Track section should be installed in each 400 ft. of track run to compensate for the cumulative differences in expansion and contraction between the steel casings and copper bus bars. Additional Expansion Track sections may be required if the installation is subjected to a wide range of temperature changes.
Expansion Track sections must be used wherever an installation is made across a building or structural expansion joint.
The standard 10' Expansion Track section is designed to provide 2” of expansion and 2” of contraction above and below the normal 10' length, at 75°F. At the time of installation, the length of the Expansion Track section must be set in accordance with the table below.
When used at points other than a building or structural expansion joint to compensate for unequal expansion or contraction between the steel track housing and copper bus bars, support the Expansion Track section by the coupling plates at each end and by the center support plates from suitable support brackets.
When used across a building expansion joint, center the Expansion Track section across the building expansion joint and support at each end from coupling plates and from the center support plates. Center support must be on the same side of the building expansion joint as the side of the expansion section stenciled “STATIONARY.”

To determine expansion (or contraction) of system casing (steel) or bus bars (copper):
Expansion = K x ΔT x L
K= Constant (from table above)
L= Length (in feet)
ΔT= Temperature change (°F)
A) A straight run of “100” track has sufficient freedom of movement between copper bus bars and steel casing to accommodate an expansion or contraction of 3/8 inch of the copper bus over and above that of the steel casing. Where a Feedrail® installation will be subjected to a high or low temperature, such that the expansion or contraction of the copper bus bars (from nominal 75 °F) will exceed the steel track casing expansion or contraction by 3/8 inch, an expansion section must be used.
Example: In a 250 foot run of “100” Feedrail® track which will be subjected to a low temperature of 15 °F, the difference in contraction between the copper bus bars and the steel track casing due to the 60 °F. temperature drop from a nominal 75 °F. will be
.0000348×250 ft. x 60 °F. temp
Difference = .522 inches
Since this is in excess of the maximum of 3/8 inch (.375”) permitted, an expansion section must be used in the run.
B) It is recommended that at least one expansion track section be installed in each 400 ft. of track run, even if only minor temperature fluctuations are expected in the area in which the Feedrail® is installed.
C) Expansion track sections must be used wherever an installation is made across a building expansion joint to prevent the building movement from causing undue stresses on the Feedrail® system.
D) The “100” Expansion joint is normally made to a nominal length of 10'-0'' and is designed to operate within the limits of 9'-10'' to 10'-2'' length of the steel casing. In addition to the above movement permitted by the steel casing, the copper bus bars are permitted 50% additional movement with respect to the casing so that the normal difference in expansion or contraction between the casing and bus bars can be accommodated be the expansion joint.
E) The air temperature at the time of the actual installing of a Feedrail® system will influence the setting of a Feedrail® expansion track section. They should be set in accordance with the table in the Building Expansion Track section directly above this section.
Elevated Temperature Use Of FR-100 System
Below is a data sheet giving the U/L approved temperature usage of Feedrail® 100 systems and the temperature restrictions based on the properties of the materials used in construction of the equipment.
The U/L approval does not apply to use in ambients over 40°C (104°F.)

In the event that the Feedrail® “100” equipment is subject to higher ambient temperature, the following information as to its operating life is offered as a guide:
A) “Rated life” based on insulation life vs. temperature is considered in excess of 100,000 hours (11.4 years) of service at rated Ampacity. (Not applicable to wearing parts such as trolley wheels and contacts).
B) Increasing the system temperature, either by increasing the ambient or the heating effect of the current through the bus bars, will shorten the life of the system by the following estimated amount:

The “100” system should not be operated so as to have any part reach 250°F (121°C). Consult factory for other conditions.
C) Factors which often accompany increased ambients (fumes, corrosion, etc.) contribute to the reduction of the service life of the equipment, often to a greater extent than temperature increases
D) Trolleys used in ambients over 104°F (40°C) should have “sealed” wheels and brush contacts, and use wire suitable for the maximum temperature expected.

Installing Sectionalizing Track
Sectionalizing Track sections are used to electrically isolate parts of a track run while permitting movement of the trolleys through that portion of the track.
All Sectionalizing Track sections are coupled in the same manner as Plain Track, shown in Joining Sections With Coupling Plate Set FR-102.
NOTE: The standard sections described have internal insulators of a size which do not prevent the interrupting of the current to the trolley. The current is not only maintained through the trolley but the circuits on both sides are electrically tied together through the trolley contacts as the trolley passes the sectionalizing insulator.
Other special sectionalizing track sections which are used in particular applications do break the current to the trolley. In these cases, two electrically connected trolleys must be used. They must be spaced sufficiently apart so that the contacts of one will be on the bus bars while the contacts of the other are passing the insulator. Unless connected in this manner, power will not be maintained to the trolley contacts as they cross the insulators and arcing at the trolley contacts will occur. Sectionalizing track sections must not be used as a circuit interrupting device.

Joining Curved Track Sections
For proper assembly of the curved track, the copper bus bar splice plates and steel track connection bars are required on either the right hand or left hand end of the curved track section.
Curved track sections are furnished with separate copper bus bar splice plates and steel track connection bars. They are supplied in a bag strapped to the track section. The above illustration shows them assembled to the right hand end of the curved track section.
Before putting the copper bus bar splice plates on to the curved track section, place the loose insulator (which comes in a cloth bag fastened to the curved track section) between the curved track end and the first insulator. (See illustration above).
The below illustrations show to which end the copper bus bar splice plates and steel track connection bars must be assembled.
If the straight track to be joined to the curved track has this type of end.
The copper bus bar splice plates and steel track connection bars must be attached to the curved track to form this type of end.
After copper bus bars and steel track casings have been connected, assemble coupling plate set to track by hooking bottoms of coupling plates into slots under edges of track casings, bring plates together, insert and tighten bolts. When complete the joint will look like the above.
If the straight track to be joined to the curved track has the above type of end, the curved track must have this type of end shown below.
The connection of the straight track to the curved track, as shown above, is made without the use of the copper bus bar splice plates or the steel track connection bars. (These are used at the other end of the curved track section.)

Mounting of Crane and Hoist Type Trolleys
Trolleys for use on Cranes and Hoists (Crane and Hoist Trolleys) are equipped with a pulling bracket with chain linkage. Brackets must be attached to the hoist or crane bridge in such a manner that the chains are on the center line of the track and the bracket is parallel to the track and 2” below the track. Flexible rubber covered cables must be used for electrical connection to each trolley.
Mounting of Special Service Trolleys
Special Service Trolleys for use on straight track runs are equipped with a pulling bracket with chain linkage. Brackets must be attached to the hoist or crane bridge in such a manner that the chains are on the center line of the track and the bracket is parallel to the track and 3” below the track. Flexible rubber covered cables must be used for electrical connection to each trolley.

- Weight of any equipment to be supported by the system.
- Fusing arrangements required.
- Number of outlets needed.
Preventive 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 inspection and main– tenance will be required.
Before additional electrical loads are added to the system it should be determined that sufficient capacity is available.
Basic Dimensions/Mounting Methods of Feedrail® ‘100’ Assembly
Examples of the methods commonly used for mounting Feedrail® “100” systems track runs are shown. These methods can be used in existing plants as well as in new buildings. Engineers and contractors will readily be able to devise other methods to suit special installations. In every case the mounting should be designed to insure a rigid installation in both horizontal and vertical alignment.
As an aid in planning mountings, the basic dimensions of the “100” systems are shown. These are offered as a guide only.
