Feedrail FH Heavy Duty Trolley Series

Heavy Duty Crane & Hoist Electrification Systems 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.

Track Supports

Supports are of heavy gauge steel. Two supports are required for each track section to provide support every five feet.

Track

Track sections consist of a brake pressed one-piece 13-gauge zinc coated steel housing and the enclosed current carrying bus bars and insulators, all factory assembeld in convenient lengths ready for easy fool-proof instalation on the job. The lower horizontal portions of the housing serve as smooth, rigid runways for the trolleys.

Heavy Duty track sections are available in various types - Plain, Door, Sectionalizing, and Expansion track sections.

Bus Bars are of hard drawn copper. They are amply proprotioned to carry the specified current or 225 / 375 / 500 amperes per pole continuously, or 300 / 500 / 575 amperes per pole intermittently, without over-heating.

Bus bar connectors assure full current carrying capacity accross the joints without interferring with the free travel of the trolley contacts.

Insulators are made of a high insulating and arc-resistant material.

Trolleys

Basically, all Feedrail® heavy Duty 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. A substantially proprotioned insulator block combines the best insulation properties with high arc resistance.

Feedrail® Heavy Duty trolleys are furnished with silver alloy BRUSH CONTACTS for movement up to 500 feet per minute. For rate of travel or conditions other than above please consult technical service group.

A polarizing tab on the chassis, operating in conjunctin 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 40 pounds per trolley are not recommended.

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.

Equipment grounding may be made by using the grounding lug within the box. track housing must be grounded through conduit or other suitable means.

Feedrail® Heavy Duty systems are designed primarily for indoor services 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-supported trolleys take off current and provide electric power for crane and hoist or other types of electrification systems.

The Feedrail® Heavy Duty systems have been specifically developed to provide safe electrification for crane bridges, monorail-hoist installations, test lines, machine tools and similar applications.

The Feedrail® Heavy Duty Systems are made up of standardized units, factory assembled for fast, complete installation without on-site fabrications.

CLOSE

Joining Straight Sections with Coupling Plate

1. Track sections must be placed so that the diamond match marks are on the same side. Fasten the two steel connection bars to the inside of the lower channel-shaped groove of the track housing so that the bars extend halfway out.

2. Bring the ends of the adjoining track sections together in horizontal and vertical alignment. Attach track connection bars.

3. Fasten the copper splice bars across the bus bar joints with the hex head locking screw as shown. (Use only locking screws provided.)

4. Hook bottoms of coupling plates into slots under edge of the track housing. Hold plates in position, put cover in place and fasten.



CLOSE

Mounting Reversible End Feed Box

1. Bolt positive pressure type solderless terminals to bus bars. Lugs should be up if power is to be brought in from top; down if brought in from the bottom.

2. Hook side plates into slots under edges of track housing. Attach end feed box frame to side plates so that conduit hole is at top or bottom to match position at which power will be brought in.

3. Connect power source to terminals. (Power supply cables should not put strain on terminals.) Fasten cover to end feed box.



CLOSE

Mounting Dead End Cap

1. Hook dead end cap side plates into slots under edges of track housing. Hold plates in position and fasten end cap in place. Mount top cover.



CLOSE

Coupling Sections with Center Feed Box

1. Join track as shown in steps 1 and 2 in Joining Straight Sections with Coupling Plate. Attach positive type solderless terminals to bus bars.

2. Hook bottom of feed box side plates into slots under edges of track housing. Place center feed box frame in place and attach to the side plates.

3. Connect power source to terminals. (Power supply cables should not put strain on terminals.) Mount the two cover plates to the center feed box frame.



CLOSE

Installing Track Hangers

1. Assemble two piece hanger set over the track section and attach to mounting bracket or other support. (Two hanger sets should be used for each 10 foot track section on approximately 5 foot centers.)



CLOSE

Installing Sectionalized 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 Straight Sections with Coupling Plate.

Note: The standard sections described in Sectionalizing Track 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.



CLOSE

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."

(2) Insert trolley. If trolley hits polarizing stop, remove, reverse 180° and reinsert. Close track doors.

(3) Mount drive bracket in a horizontal plane as shown below. Chains must be parallel with and on the center line of the track.

When wiring trolleys, a looped flexible wire cable should be used (not rigid or flexible conduit). The flexible cable should be attached to the trolley so no strain is placed on the trolley by the cable. Trolleys should be allowed to travel freely in the track run.

Installation Planning

Before a Feedrail® system can be planned or an estimate of the cost prepared, the electrical and mechanical requirements that the system must meet should be known. The following outlines list the basic data needed for all applications and the additional data required for various specific applications.

Basic For All

  1. Describe in detail the purpose of the Feedrail® Heavy Duty System. Will it be used with existing equipment?
  2. How many conductors will be required?
  3. What voltage and current is to be applied to each conductor? Where is the power source located?
  4. Details about any special requirements or conditions which the installation must meet such as moisture, corrosive fumes, high or low temperatures, etc.

For Electric Cranes

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:

  1. Keeping the System dry and clean to prevent electrical leakage or “shorts” across the insulation.
  2. Maintaining electrical continuity by keeping bus bar contact surfaces clean and joints tight.

Mechanical Maintenance requires:

  1. Preventing excessive wear.
  2. Replacing parts showing excessive wear.

The following Preventive Maintenance procedure, periodically performed is recommended:

  1. 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.
  2. Clean bus bars with Feedrail® Track Cleaning Tools.
  3. Blow out all foreign particles which have accumulated inside the track.
  4. 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 maintenance will be required.

Before additional electrical loads are added to the system it should be determined that sufficient capacity is available.

Trolleys

The same efficient engineering and clean-cut construction which is a hallmark of the entire Feedrail system is evident in the internally track supported Heavy Duty trolleys.

The chassis of these trolleys is of one piece heavy gauge steel. It is equipped with heavy duty enclosed ball-bearing wheels for support; horizontally mounted ball-bearing guide wheels running in the slot of the track to prevent slewing; and ball-bearing wheels on pivoted arms of the undercarriage to prevent upthrust. This wheel combination assures smooth, easy running trolleys.

The insulator-contact assembly consists of a substantially proportioned mechanically strong arc-resisting insulator block on which the contact brushes are mounted and held in true alignment. Spring keep the brushes in continuous firm contact with the bus bars. The insulator-contact assembly is fastened by machine screws and can be removed as a unit.

Specially designed heavy duty silver alloy brush type contacts assure full current carrying capacity. Brushes are individually spring loaded and maintain full contact pressure and alignment with the bus bars at all times.

A heavy gauge sheet steel terminal box with removabe side cover is supported by the trolley chassis. This box serves to enclose the solderless type pressure connectors which are used to make cable connections to the trolley.

Lugs take either aluminum or copper cables. Heavy duty cable grips prevent strain on the terminals.

Trolleys are designed for operation at speeds up to 500 feet per minute. A bracket and chain linkage is provied for connecting the trolleys to the powered equipment. Chains are factory adjusted for correct propelling of the trolley in the track run.

Cleaning Tools

These special trolley-mounted Dust Remover and Bus Bar Cleaners are quickly and easily used to keep a Feedrail "Multi-Conductor" System in prime working condition. Ther are inserted through the door track section, with the power off, and simply pulled back and forth along the length of a track run, cleaning all bus bars at the same time. Their frequency of use will depend upon the severity of foreign matter accumulations, although a regularly scheduled preventative maintenance program is highly recommended.
