To add an anchor to a boom/gantry, choose a structure that can support anchoring equipment or edit an already placed structure so that it can.
To access the anchoring equipment, navigate to the ‘Wire Manager’ located in the Linear Draft toolbar and then click ‘Edit’ on the structure that you want to be an anchor.
The 'Configure' form will be displayed.
Enter the required configuration of the anchor by choosing 'Anchor' in the 'Support' drop-down menu. When 'Anchor' has been chosen the wire will be automatically updated to 'out-of-running'.
Messenger Wire, System Height and Contact Wire are all configurable at this point too. Once you have configured the wire point, tick the 'Equipment' checkbox. The configure form will expand to show the available attachment points.
Choose attachment point 'Gantry'.
SPS can now be selected. Click 'Add SPS' and the 'Add SPS' form will be displayed.
Select the SPS from the drop-down menu and input a value in either the 'Distance From Wire' field or 'Offset from Support' field - both fields work in conjunction with one another and when a value is updated in one field, the other is adjusted automatically, and vice-versa.
The distance input here should be the distance along the gantry from the mast that is identified in the 'Support' field on the 'Configure' form.
Some SPS will allow rotation on the gantry, if the selected SPS is required to be rotated, then input the rotation value in the 'Rotation' field.
Once confirmed, Linear Draft will automatically add a Droptube. To edit the Droptube, click 'Edit Droptube' at this point.
The SPS and Droptube will now be visible on the 'Wire Configure' form.
A bracket can now be added, click 'Add Bracket' and the 'Add Bracket' form will be displayed.
Select the bracket from the drop-down menu.
At this point, there will be two options for each type of available anchor, ‘Front’ and ‘Back’. This is to identify on which side of the mast the anchor equipment is to be placed.
‘Front’ is determined from looking at the structure in a forward facing cross sectional view and ‘Back’ is the reverse side. Once you have chosen the bracket, click ‘Confirm’.
The 'Configure' form will again be displayed. The live preview of your model will show the anchor equipment in the current arrangement.
To accept, and place within your model, click 'Confirm'.
