Structural Design User Guide

Rung Ladder : Detail Mode

The Detail Mode is intended for use by structural designers to fully define the rung ladder, by selecting a default, an assembly and the specification references of the ladder components.

An rung ladder element created in Layout may be modified to a detailed representation without deleting and re-creating the element.

General Attributes

The functionality available for the General Attributes of the Rung ladder in the Detail Mode is identical to that described in the Layout mode, for more information refer to General Attributes.

Position and Elevation

The functionality available for the Position and Elevation of the Rung ladder in the Detail Mode is identical to that described in the Layout mode, for more information refer to Position and Elevation.

Ladder Assembly

The Ladder Assembly part of the Create Rung Ladder window is automatically populated with all of the available assemblies for selection that contain the selected exit type. A 3D graphical representation of the assembly is also displayed.

Select Next to display the Specifications part of the Create Rung Ladder window.

Select Back to return to the Position and Elevation part of the Create Rung Ladder window.

Specifications

The Specifications part of the Create Rung Ladder window displays all the available specifications for the rung ladder from the defaults.

Dependent upon the choices made by the user on previous parts of the Create Rung Ladder determines which specifications are available for selection.

From the Ladder Specifications part of the Create Rung Ladder window:


Rung:	The selected defaults determines which rungs that can be used for different width ranges. Once the user has selected the width of the ladder, the rungs available for selection are then filtered.
Stile:	The selected defaults determines which stiles that can be used for different height ranges. Once the user has selected the top and bottom elevations and the height of ladder has been calculated, the stiles available for selection are then filtered.

From the Cage Specifications part of the Create Rung Ladder window:


Hoop:	The hoop specifications available for selection are determined by the selected defaults.
Bar:	The bar specifications available for selection are determined by the selected defaults.

From the Gate Specification part of the Create Rung Ladder window, the gate specifications available for selection from the drop-down list are determined by the default specification. The default is None.

Select Next to display the Ladder Details part of the Create Rung Ladder window.

Select Back to return to the Ladder Assembly part of the Create Rung Ladder window.

Ladder Details

The Ladder Details part of the Create Rung Ladder window is populated with the selected and calculated values, most of these values are constrained by the specifications. Any of the ladder dimensions can be modified as long as the dimensions remain within the maximum and minimum tolerances of the associated standard.

If the user enters a dimension which is not within the maximum and minimum tolerances of the associated standard, an appropriate Error window is displayed.

Any of the dimensions displayed in the Create Rung Ladder window can be labelled in the 3D view. To label the dimension, click dimension alongside the dimension field.

Ladder Details

The Ladder Details part of the Create Rung Ladder window is populated with the selected and calculated values, most of these values are constrained by the specifications.

The SLH application endeavours to calculate the initial rung spacing to be as close to the associated standard and therefore makes the bottom rung spacing equal to the rung spacing.

If required the user can modify the rung spacing and as a result the bottom rung spacing. From the Ladder Details part of the Create Rung Ladder window, input the new rung spacing into the Rung Spacing field, then press enter.

To return the rung and bottom rung spacing back to that of equal spacing, click the = icon.

Stile/Cage Exit Width

The Cage Details part of the Create Rung Ladder window is only displayed if the Omit Cage or Omit Top Rung check box on the General Attributes part of the Create Rung Ladder window is selected.

The Cage Details part of the Create Rung Ladder window is populated with the selected and calculated values, most of these values are constrained by the specifications.

Other cage details are inactive dependent on the selections made by the user:

Flare Offset - only available if an assembly with a cage flare has been selected.

Cage Clearance (Side Exit) - only available for side ladders.

The SLH application endeavours to calculate the initial cage hoop spacing to be as close to the associated standard and therefore makes the top hoop spacing equal to the cage hoop spacing.

To return the cage hoop and top hoop spacing back to that of equal spacing, click the = icon.

Select Build Rung Ladder to create the rung ladder element, in the database and close the Create Rung Ladder window.

Select Back to return to the Specifications part of the Create Rung Ladder window.

Rung Ladder Summary

The Rung Ladder Summary part of the Create Rung Ladder window, is populated with the main attributes of the rung ladder. If required, before the creation of the rung ladder element the user can select the attribute by name and modify it from the displayed part of the Create Rung Ladder window.
