Check/Assign Multi Lift ( Modeling )

Tool summary :

  • Lets you check liftability of a multi-lift and, optionally, assign the multi-lift to a crane's crane placement.
  • The Multi Lift window (shown below) opens in step 4 .
The Multi Lift window opens when you Check/Assign Multi Lift . It also opens for an " Edit " operation done using Manage Lifts when the selected lift is a multi-lift.
  • The multi-lift that you define using the window shown above can be for checking purposes only. You have the option, in step 5 , to actually assign the multi-lift to the crane placement .
  • Model > Crane options require a license. Without that license, crane options are not available in the SDS2 program.

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

You must be in Modeling and do either step 1 (preselection) or step 3 (in-tool selection) to perform this operation. Before Check/Assign Multi Lift , you should Open ( Ctrl + o ) a view that shows the crane placement you want.

1 (optional) : Select the crane placement that you want to select members from for inclusion in the multi-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 Multi Lift using any one (1) of the following methods:

Method 1 : Click the Check/Assign Multi 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 Multi Lift .

Method 3, 4 or 5 : Check/Assign Multi 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 .

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 Multi-lift window opens.

4a : Press the " Add " button to choose members that you want included in the multi-lift. Make any additional changes that you want on the 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 ).

Tip: For step 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.

Multi-lift

--- Included members ---------------

23B1[97]
26B1[116]
11B1[124]




A multi-lift is a lift that consists of multiple members that are lifted together but placed individually. The set point " Location " for a muli-lift is the center of gravity of the one member that is farthest from the crane.

FYI: An " Assembly " is also a lift that consists of more than one member, but the members in a multi-lift are set down together. The set point " Location " for an assembly is the center of gravity of the assembly's component members.

lets you select on the Select Lifts window those members that you want to include in the multi-lift. The Select Lifts window lists member lifts that have been assigned to the crane placement that you selected in step 1 or, if you didn't do step 1, step 3 . The members that you select will be shown in the list to the left of the " Add " button.

Note: If the crane placement you selected has no lifts assigned to it, when you press " Add " you will get a message that states, " There are no lifts to include in a multi-lift ." If you get this message, you should press the " Cancel " button to end this operation.

deletes the selected member(s) from the lift. Be aware that you cannot delete all the members that are listed. If you do, you will get a warning when you press the " OK " button, and you will not be allowed to leave this window until you add a member to the lift. To restore members you have deleted, you can press the " Reset " button.

Pick Location: No change or Select location or Enter location . You may want to move a lift closer to the crane to make it easier to lift.

' No change ' keeps the " Pick Location " where it is 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 a 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.

Key concept: When you open the Lift Configuration window by invoking Manage Lifts then selecting a multi-lift then pressing " Edit " then pressing " Edit Config ," the multi-lift may have non-auto settings (" AUTO " not checked). When you select the same members to open the same-named window using Check/Assign Member Lifts , all settings will initially be auto (" AUTO " checked).

  To close the Multi Lift window:

"OK" closes the Multi-lift window and saves any changes that you made to it.

For a Check/Assign Multi 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 Multi-lift window will be retained.

"Cancel" closes the window without making any changes.

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