Check/Assign Load Lift ( Modeling )

Tool summary :

  • Assigns a load lift to a crane placement. Or lets you check a load lift's Lift Information .
  • The User-Defined Lift window (shown below) opens in step 4 .
The User-Defined Lift window opens when you Check/Assign Load Lift . It also opens for " Edit " operations done using Manage Lifts when the selected lift is a user-defined lift.
  • A load lift can be used to model the lift of an item, such as a piece of heavy equipment, that is not shown in the model.
  • When you select the crane placement, you select its associated crane and set the default Lift Configuration settings. Actually assigning the lift to the crane placement is optional, in step 5 .

   Check/Assign Load Lift (step-by-step instructions) :

You must be in Modeling and do either step 1 (preselection) or step 3 (in-tool selection) to Check/Assign Load Lift . Before Check/Assign Load Lift , you should Open ( Ctrl + o ) a view that shows the crane placement you want and the location where you want to place the load. Usually, you will want to open a plan view that is at the elevation of the set location.

1 (optional) : Select the crane placement that you want to set the default Lift Configuration settings and to which you can optionally, in step 5 , add the lift. There's multiple ways to do this.

Select Items bindings

Method 1 : Move your mouse pointer ( ) so that it hovers the crane placement that you want and so that it (the crane placement) is highlighted.. A balloon description (if that feature is turned on) will identify the crane placement's " Placement name ." Left-click ( Select ) to select the placement. Go to step 2.

Method 2 : Move your mouse pointer ( ) so that it hovers the crane placement that you want. Right-click ( Menu ), choose " Select Other " on the context menu , select the crane placement's name. Go to step 2.

Method 3 : In the Model Tree , click the [+] for the " Cranes " category, then click the [+] next to the crane name, then select the name of the placement you want to select. When you select the placement in the Model Tree , it is selected in the model. Go to step 2.

2 . Invoke Check/Assign Load Lift using any one (1) of the following methods:

Method 1 : Click the Check/Assign Load Lift icon. The icon can be taken from the group named ' Model -- Cranes ' and placed on a toolbar (classic) or the ribbon (lightning).

Method 2 : If " Modeling layout style " is ' Classic ', you can use the menu system to choose Model > Crane > Check/Assign Load Lift .

Method 3, 4 or 5 : Check/Assign Load Lift can also be configured to be invoked using a keyboard shortcut , the context menu , or a mode . For the lightning interface, this configuration is done using Customize Interface .

Method 6 : Right-click ( Menu ) and choose Crane > Check Load Liftability on the context menu .

3 . Skip this step if you already selected a crane placement in step 1.

Select One Item bindings

3a (if you didn't do step 1) : Select One Item mouse bindings become active, and the status line prompts you to " Locate crane placement ." Left-click ( Select ) one crane placement .

4 . The User-Defined Lift window opens.

4a : Enter the " Load weight " and other desired lift specifications that you want on the User-defined lift window, then press the " OK " button to continue.

4b (if you chose ' Select location ' for " Pick location ") : The status line prompts you to " Locate pick location ." Optionally select a Locate option (e.g. INCL ), then move your mouse pointer ( ) so that the point location target ( ) snaps to the point that you want to be the pick point, then left-click ( Locate ).

4c (if you chose ' Select location ' for " Set location ") : The status line prompts you to " Locate set location ." Optionally select a Locate option (e.g. INCL ), then move your mouse pointer ( ) so that the point location target ( ) snaps to the point that you want to be the set point, then left-click ( Locate ).

Tip: For steps 4a and 4b, the X, Y, Z display tells you the coordinates of a point.

5 . The Lift Information window opens. Most of the settings on the window are read-only. The window reports the calculations required to determine the " Status " of a lift.

Alternative 1 (add the lift to the placement) : Check the box for " Assign to placement ," then press the " OK " button. Tip: You can use Manage Lifts to confirm that the lift has been added to the placement.

Alternative 2 (keep the lift unassigned) : Press the " Cancel " button. Or, if you insist on pressing " OK ," uncheck the box for " Assign to placement " then press the " OK " button.

User-defined Lift

Load weight: The weight of the item to be lifted.

This is reported as the " Load weight " on the Lift Information window.

Description: The identity of the lift. For example, if the lift is a piece of machinery, you might type the name of the machine. If the lift is a material, you might type the material type.

This " Description " will be shown on the selection list for the Lifts for placement xxx window.

The " Description " is also reported as part of the " Description " on the Lift Information window.

Pick location: No change** or Furthest laydown point or Select location or Enter location . The ' No change** ' option appears for " Edit " operations done using Manage Lifts . The ' Furthest laydown point ' option appears for Check/Assign Load Lift operations. One reason to set a " Pick location " is to place a user-defined lift closer to the crane to make it easier to lift.

' No change ' keeps the " Pick location " where it is at. It is the default choice made for " Edit " operations done using Manage Lifts . The " X " " Y " and " Z " coordinates under " Enter location " are the point where the " Pick Location " is currently at.

' Furthest laydown point ' uses the furthest laydown point that is associated with the crane placement that was selected in step1 or, if you didn't do step 1, step 3 .

' Select location ' lets you locate a point in the model. Point location options such as INCL or AUTO or INCM can be used to locate the point.

' Enter location ' lets you enter " X " " Y " and " Z " global coordinates to define the pick point.

Set location: No change** or Select location or Enter location . The ' No change** ' option appears for " Edit " operations done using Manage Lifts .

' No change ' keeps the " Set location " where it is at. It is the default choice made for " Edit " operations done using Manage Lifts . The " X " " Y " and " Z " coordinates under " Enter location " are the point where the " Set location " is currently at.

' Select location ' lets you locate a point in the model. Point location options such as INCL or AUTO or INCM can be used to locate the point.

' Enter location ' lets you enter " X " " Y " and " Z " global coordinates to define the set point.

opens the Lift Configuration window for the individual lift. " AUTO " settings on that window apply the choices made to the Lift Configuration for the crane placement that you selected in step 1 or, if you didn't do step 1, step 3 .

VIDEO The " Lift Config " button on the crane edit window ( crawler or tower or truck ) sets the defaults for crane placements , which in turn sets defaults for individual managed lifts. On an individual managed lift , you can make choices that override the defaults. (Recorded in SDS2 Site Planning , v7.3.)

Key concept: When you open the Lift Configuration window by invoking Manage Lifts then selecting a user-defined lift then pressing " Edit " then pressing " Edit Config ," the user-defined lift may have non-auto settings (" AUTO " not checked). When you Check/Assign Load Lifts , all settings will initially be auto (" AUTO " checked).

   To close the User-Defined Lift window:

"OK" closes the User-defined Lift window and saves any changes that you made to it.

For a Check Assign Load Lift operation , proceed to step 5 of the step-by-step instructions.

For an " Edit " from the Managed Lifts window , any changes that you made on the User-defined Lift window will be retained.

"Cancel" closes the window without saving any of the changes you made.

"Reset" reverts the state of the window back to how it was when you first opened it.
