Monorail Trolleys can be furnished with any one of the load suspension fittings illustrated on this page. When use with two-wheel trolleys add extra to price of trolley. No. A-120 Hook and No. A-121 Eye are not recommended for use with hoists.

Special trolleys can be made up by combining standard parts with special equipment to meet the particular requirements in handling loads on racks or other carriers of similar nature.

Conductors bars for curves are cut to the exact length required and are wired to the rail on the side of the curve on which they are to be mounted.

Conductor bars and insulators are shipped knocked-down and must be assembled on the rail as installed.

Mounting of the curved conductors is identical with that of straight track. The splice point on the conductor bars is at the center of the rail splice except when curves enter electrified switches.

Any curve or those bent to special radius can be furnished with conductors.

Curves in this series are for use with the Electrified Tongue Switches. Complete dimensional data is offered in the drawing and table below which lists the various standard switch groups. Curves are accurately bent and, although occasionally sprung in shipment, they may be easily reformed to meet track layout requirements.

In order to provide against end thrust when using Monotractors on electrified No. D-401 track, it is necessary that track be rigidly braced at the curve and switch connections. This can be done by the use of a short Girder Rail section at the approaches to and in the Reinforced Curves shown on this page.

These curves are build up similar to Girder Rail with heavy steel web plates welded between the twin section of No. D-401 track. Short sections of heavy angle are welded to the top of the web at all support points.

With this rigid arrangement Monotractors are protected against excessive way when operating around curves and through switches.

Collectors are of the sliding-shoe, self-cleaning type. They are made of hard copper alloy, set head springs. This provides self-adjustments for irregularities in the conductor and assures correct alignment at all times. The head spring is mounted on standard American monorail collector brackets which carry double coil springs for proper contact with the conductors.

Contact face of the shoe is contoured to allow for any possible misalignment of conductors at entrance to a movable section of track such as at switches and crane interlocks.

Collector shoes can be easily removed for replacement by loosening two bolts and disconnecting the lead in wire.

Illustrations give operating features of the electrified track opener for horizontally hung fire doors. Special application drawing will be furnished for No. JH-1094 Track Opener for vertical doors.

Where electrified Monorail track runs through doorways, this track permits automatic or manual closing of doors with provision for return of track section when door is re-opened. Operation is extremely simple since, when the door strikes the lever arm releasing latch pin, the 6-inch swinging section turns on a hinge permitting door to close. When door is re-opened, the spring pulls the open section back into position where it is again latched to connecting track.

For use on 11" and 13-1/2" depth Girder Rail only.
