Crane capacity check

Crane capacity check


Field / button Description
Table view                                                                            This table shows a list of cranes including the crane name, visualization color of the crane and the number of assemblies/cast units currently assigned to the crane. Use the table to select the active crane for assigning assemblies or cast units to the crane, and for visualizing the crane lifting capacity.
Click the button to open the color dialog box to change the color of the crane.
Edit cranes Click this button to open the Crane properties dialog box. In this dialog box, you can edit the properties of the crane and/or create new cranes. The usage of the dialog box is explained in the next paragraph.
Add crane Click this button to open a dialog box where you can select one or more existing cranes to be added to the list in the table view. Notice that if you do not have any cranes defined, this button is disabled. In that case, click the Edit cranes button to define a crane.
Remove crane Click this button to remove the crane from the list in the table view. Select the crane or cranes in the list and click the button.

If any assembly or cast unit is assigned to the removed crane, the assemblies and/or cast units are unassigned from the crane.

Preview Click this button to see a preview of all selected cranes in the model view.
Select by crane Click this button to select the assemblies and/or cast units assigned to the cranes selected in the table view.
Assign to crane Click this button to assign the selected (in model view) cast units and/or assemblies to the selected crane (in the table view).
Unassign (selected) Click this button to unassign all selected (in model view) assemblies and/or cast units from any crane.
  From this list, you can select the current coloring scheme.
  • No coloring - no coloring in the model view
  • Color by crane - when this option is selected, the assemblies and/or cast units are colored with color of the crane
  • Color by utilization ratio - when this option is selected, the assemblies are colored according the utilization ratio. Colors from cyan to green indicate that the assembly can be lifted. An assembly with red color is either too far from the crane or is to heavy to be lifted at distance from the crane using the color 'scale' below. 

Note that the last option is coloring only assemblies/cast units assigned to the currently selected crane(s). The easiest way to select all cranes is to click the leftmost white box in the header row of the table view.

Delete the row by selecting the row and clicking the Delete button.

Preview Click this button to see the crane lifting diagram visualized in the model view (see the example below).


Custom template properties

This extension implements two new custom properties related to the crane lifting capacity.

Template field Description
CUSTOM.CRANE_CAPACITY This is the utility of the crane lifting capacity as a decimal number. When the value is in the range of 0.0 ... 1.0, the assembly/cast unit can be lifted with the given crane from the given crane location. A value greater than 1.0 indicates that the assembly/cast unit is either too far or too heavy.

A value -1.0 (negative) indicates that the crane name is not set or that the crane is missing.

The crane name is stored into the assembly/cast unit using the user-defined attribute:


The crane location is always taken from the crane file.

CUSTOM.CRANE_DISTANCE This is the distance between the center of the gravity point of the assembly and the location of the specified crane.

USimperial weights are given in kg in the model preview.

Thanks for the notice Robert. I created a defect about this issue to our development system, id: 132190.

by Jason Carpenter

Any chance you can add an option for inserting an item or reference model at the location of the crane specified in the dialog box?
This way we can show the actual crane with its correct radius's.

Thanks for your input, I added your request to our development list, id: TEX-3475.

Thanks Elja, this would be very helpful!

I tried to install version 2017.0.3 for TS 2017 using Extension Manager. A notification came out telling me that "Unable to import the selected extension as the package signature is invalid.". Any ideas what to do?

by Harri Niemi

Updated with new TSEP-installer for TS2017, which now installs correctly from extension manager.
