Voltage

600 volts A.C. - 250 volts D.C.

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.

Installing Sectionalized Track
Typical Feedrail InstallationSectionalizing 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.

Installing Expansion Track
Typical Feedrail Installation
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.

Length Settings for Standard 10' Expansion Track
Installation Temperature Distance in Feet *
100 200 400
100°F 9'11-3/16" 9'11-5/8" 9'11-1/4"

Mounting of Heavy Duty Trolleys
Typical Feedrail Installation(1) Press latch pins on bottom of door track section together and open doors.

(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® Heavy Duty 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.

NOTE: Basic dimensions of the Feedrail Heavy Duty System and various methods of mounting and supporting the system are given on page 82 and 84.

For Electric Cranes

5. Sketch giving number, location, length of crane runways and length of bridge. Show location of building expansion joints, if any.
6. How many conductors will be required on each bridge run? - How many for power? - for control? How much current must each conductor carry?
7. What is the maximum travel speed of the bridge? - of the hoist?
8. List of the crane’s motors — main hoist, auxiliary hoist, bridge travel, trolley travel — giving the type (D.C., wound rotor, squirrel cage, etc.) of each motor and its horsepower and full-load ampere rating.

For Electric Hoists

5. Plan view sketch of the rail system on which the hoists will travel, giving the length of run of straight sections, radii of any curves and dimensions of any switches. What is the minimum distance from Feedrail® to crane rail in order to clear hoist? Show location of building expansion joints or expansion joints in the structure from which the Feedrail® will be supported.
6. How many hoists will be used and what is the horsepower and full load current rating of each? Include horsepower and full load current rating of travel motors of any of the hoists that are motor propelled. What are the maximum travel speeds?

For Production Machines

5. Plan view sketch with dimensions showing the location of the Feedrail System.
6. Indicate the number of conductors required and give voltage and amperage requirement of each. Give horsepower and full load current rating of each motor.
7. List any other equipment that will be powered by the Feedrail® and give its full load current rating.

For Special Requirements

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, and
(2) maintaining electrical continuity by keeping bus bar contact surfaces clean and joints tight.

Mechanical Maintenance requires
(1) preventing excessive wear and
(2) replacing parts showing excessive wear.

The following Preventive Maintenance procedure, periodically performed is recommended:
(a) 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.
(b) Clean bus bars with Feedrail® Track Cleaning Tools.
(c) Blow out all foreign particles which have accumulated inside the track.
(d) Check trolleys for free movement within the track.

(2) 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.
