Associated Commands:         [Setup]

Trapeze Hangers consist of two separate hangers inserted at the same location. One is the trapeze member itself and its fasteners (trapeze hanger). The other is the hanger that fastens the pipe to the trapeze primary hanger.

If no hanger was previously set up, then the first time this command is selected, the Hanger Setup dialog box will appear. Make sure the Hanger Length is set as Specified Length and enter the elevation and other required criteria. Press OK to see the Trapeze Hanger Setup dialog box.

The Primary Hanger field shows which hanger was set up through the Hanger Setup dialog box. The Trapeze Hanger value corresponds to the available trapeze styles. There are three factory setups to choose from.

Type 17 uses angle iron for a support brace, type 17A uses a pipe and type 17B uses a Unistrut. All types include the clamps, brace, and other necessary hardware, as well as a standard #01 hanger. The #01 hanger specification, or another trapeze to pipe configuration, must be set through the Setup command before the trapeze is inserted. The size of the supporting trapeze member is determined by settings in the HydraLIST database, specifically in the Assembly area. Refer to the HydraLIST manual for more information on how to adjust these settings.

The Overhang value is the extra length required for the supporting angle iron or pipe on each end. For example, if the distance between the supporting steel joists is 5’, the brace for the trapeze should be longer than this ( e.g. 6”-12”).

The Rod Deduction is the length which the hanger rod must be reduced from the standard #01 hanger as specified in Setup, to accommodate the height taken up by the trapeze. The #01 hanger length must be Specified and not Computer Generated for Rod Reduction to occur.

To install a trapeze hanger, first setup the type #01 hanger with the Setup command. Next, select Trapeze from the toolbar and the Trapeze Hanger Setup box will appear. Below is a main ready for a trapeze hanger insertion. The steel joists are on 5’ centers.

The Trapeze Hanger Setup box is configured as shown. Press OK and HydraCAD will prompt you to pick the steel to hang from. Pick both of the joists.

All pipes between the two picked points will receive a trapeze hanger.

The trapeze tag is inserted as shown.

The tag actually represents two hangers. The hanger with no visible attributes contains the length of pipe, angle iron or Unistrut required for support. The other is the #01 hanger.

The attributes of both hangers will be picked up by the AutoList routine.

The HydraLIST stocklist report will include the correct hanger ring, beam clamps, threaded rod, and support brace. The correct rod lengths will be calculated and shown on the report.
